Alright, draw both rectangles next to each other and write down the given for both ^_^: We have the following given for the big rectangle which is: L = 20 ft W = 20 ft and the general formula for the area of a rectangle is : \[A = lw = (20)(8) = 160 ft^2\] is it clear now? ^_^
anonymous
  • anonymous
do you want x and y = sides of the smaler rectangle?
anonymous
  • anonymous
yes

Starica my life saver yes i want the sides of the smaller rectangle
anonymous
  • anonymous
Hmm, okay, I think I have found a relationship between the 2 rectangles, I hope this helps. A1 = xy A2 = Lw Since both rectangles are similar then they are proportional , so yu'll have the following relationship: \[A2/A1 = lw/xy = 160/20 = 8\] so : A2 = 8(A1) does this help? :)
anonymous
  • anonymous
I dont get what your saying. I have to fine what x and y equals. it has to do witch similar figures
anonymous
  • anonymous
lol, I have showed you the relationship between both rectangles. I'm not sure how to solve it, but I have given you a relationship, can you figure that out from here?
anonymous
  • anonymous
To find the sides, you have to know the proportionality of the sides and areas
anonymous
  • anonymous
here what my problems looks like

  • anonymous
Like I have said, since they are similiar then the sides are proportional so you'll have :\[x/y = 8/20\] cross multiply and solve for x or y, I'll solve for x first and you'll get : 8x = 20y x = (20/8 )y x = (5/2)y plug this x in the area of the smaller rectangle: A1 = xy 20 =[ (5/2)y ] y \[20 = (5/2)y^2\] \[y = \sqrt{40/5}=\sqrt{8}= 2\sqrt{2} ft\] now plug this y in the equation we have found which is : \[x = (8/20) y =(8/20)(2\sqrt{2}) = (4\sqrt{2})/5 ft\] Correct me if I'm wrong please ^_^
anonymous
  • anonymous
I guess I'm wrong since it's not equal to 20 ft^2 :(
anonymous
  • anonymous
yes gosh i hate geometry
anonymous
  • anonymous
lol, don't say that, give it a one more try, I'll try again :)
anonymous
  • anonymous
if you cant im just not going to do it i get a50 or something
anonymous
  • anonymous
angoo can you help out a bit please? :)
anonymous
  • anonymous
Lol, I didn't say I can't, I still didn't stop thinkin, I'm going to give it a one more try
anonymous
  • anonymous
okay, thank you
anonymous
  • anonymous
np :)
anonymous
  • anonymous
hmm... both rectangles are supposed to be simmilar, right? so the ratio of their width to lenght is the same
anonymous
  • anonymous
yes
anonymous
  • anonymous
ok, so the first rectangle is 20ftsq = x * z the second is 160ftsq = 8 * 20 so...
anonymous
  • anonymous
160/20 = x/8 * z/20
anonymous
  • anonymous
so what does x and y equal of the smaller square
anonymous
  • anonymous
How is geometry going to help me in my life anyways
anonymous
  • anonymous
so, we have to find the ratio first, which is, 160/20=8
anonymous
  • anonymous
life is geometry martin, everything around us is made up of geometric measurements ^_^
anonymous
  • anonymous
which means that x of the smaller triangle is 8 times smaller than x of the big triangle, and same goes for z
anonymous
  • anonymous
so..
anonymous
  • anonymous
x = 8/8 = 1ft z = 20/8 = 2.5ft
anonymous
  • anonymous
am i wrong mimi?
anonymous
  • anonymous
hmm, still not equal to 20 ft^2 angoo, but you were close though!
anonymous
  • anonymous
excellent :)
anonymous
  • anonymous
WHAT???
anonymous
  • anonymous
im confused
anonymous
  • anonymous
You got the ratio idea right
anonymous
  • anonymous
oh, i see now :D
anonymous
  • anonymous
martin the area of the smaller rectangle is : A = xy and the area is given which is = 20 ft^2 so (x)(y) must be equal = 20.
anonymous
  • anonymous
yes i know
anonymous
  • anonymous
And you must know the ratio between both rectangles since both are similar :) which is 8 just like andy has said. Did you get that part?
anonymous
  • anonymous
so x = 4 and y = 5
anonymous
  • anonymous
exactly! :)
anonymous
  • anonymous
since: A2 = 8 A1 then A1 = A2/8 just like what you have done! excellent ^_^
anonymous
  • anonymous
i am SOOOOO bad at maths :( *crying out loud desperatelly and emmotionally*
anonymous
  • anonymous
LOL! angoo, you were close ^_^, but martin that doesn't give 20 ft^2 either. X is correct, but what about y?
anonymous
  • anonymous
LOL :D, just kidding, but my exams to university are approaching, in ONE week
anonymous
  • anonymous
well thank you guys i really appreciate what you guys have really helped me. I hate high school math and my teacher who cant even teach
anonymous
  • anonymous
work hard and good luck!
anonymous
  • anonymous
np :), but did you get the idea martin?
anonymous
  • anonymous
yes. I hope i get it right its really late and i have a to study for world history and do this homework
anonymous
  • anonymous
the problem is, I have no idea what to study... there are hundreds of topics :( well, not a big deal anyway, if I fail, I will just join the military...
anonymous
  • anonymous
study the history then wake up early in the morning when your brain is fresh and you'll figure what (y) is ^_^
anonymous
  • anonymous
on i cant im not a morning person
anonymous
  • anonymous
don't say that andy, you must have high hopes and ambitions.
anonymous
  • anonymous
i have to wake up in 3 hours
anonymous
  • anonymous
damn it, I would really love to have your optimism
anonymous
  • anonymous
well you've got to, it has been proven scientifically that the brain mostly absorbs between 4 am - 7 am :) try to wake up during these times :)
anonymous
  • anonymous
you're a great computer -user, you can do anything!
anonymous
  • anonymous
just have faith in yourself :)
anonymous
  • anonymous
and trust your abilities ^_^
anonymous
  • anonymous
highschool math must of been a breeze for you guys
anonymous
  • anonymous
well, I could start OpenStudy2, or even FaceBook 2 for that matter :D
anonymous
  • anonymous
well, I got an A in my final maths exam in high, but forgot half of everything now, just half a year after finishing
anonymous
  • anonymous
you have no idea martin, I wasn't even that good in math during high school, but I worked hard in my last 2 senior years and have aced the subject ^_^ . I didn't do good because I didn't get it, but when you fully start to understand mathematics, every mathematical problem will seem simple and clear to you :)
anonymous
  • anonymous
well i hope college isnt this bad, i hope the teachers actually teach
anonymous
  • anonymous
Don't say that andy, it's there sometwhere in your head but you've got to refresh you mind that's all ^_^, nothing can be forgotton, everything is stored up in the unconscious :)
anonymous
  • anonymous
they do martin, but try not to outsmart them, they don't like it :)
anonymous
  • anonymous
well good, cause my teacher cant teach to save her life she ignores our questions
anonymous
  • anonymous
especially you andy, with your great computer skills, they'll consider you as a threat, just do your work and keep quite ^_^
anonymous
  • anonymous
I don't trust a WORD that business subject teachers are teaching me
anonymous
  • anonymous
lol, in school, you can control the teacher :) but in college you can't
anonymous
  • anonymous
I want to major in some type of computer thing
anonymous
  • anonymous
AWESOME! :) what are you most into to?
anonymous
  • anonymous
into*
anonymous
  • anonymous
because, if they are so good in business, how come they are still teaching and not living in a private island?
anonymous
  • anonymous
I love ....... :)
anonymous
  • anonymous
lol, that's the first step in getting a job andy
anonymous
  • anonymous
im really good at computers like i like to learn about technology and things of that nature
anonymous
  • anonymous
you love? what? programming ! we know lol
anonymous
  • anonymous
not exactly.....
anonymous
  • anonymous
computers and stuff?
anonymous
  • anonymous
I love something that most people dont understand and think that it is bad and stupid...
anonymous
  • anonymous
you will martin, set that as your goal and you'll reach it and you'll never fall on your knees in times of hardships, you'll fall standing because you have a dream :)!
anonymous
  • anonymous
what is it andy? :)
anonymous
  • anonymous
Be yourself because you were born this way
anonymous
  • anonymous
I am afraid you will condemn me if I tell you
anonymous
  • anonymous
exactly :)
anonymous
  • anonymous
haha (gaga)
anonymous

oh come on, you know me, what is it? ^_^
anonymous
  • anonymous
who cares we are who we are
anonymous
  • anonymous
I never judge ppl , I accept them as they are :)
anonymous
  • anonymous
yes
anonymous
  • anonymous
^_^
anonymous
  • anonymous
ok, well one of my passions is Hacking
anonymous
  • anonymous
I dont like highschool because people pick on you for the dumbest things
anonymous
  • anonymous
that's great :)
anonymous
  • anonymous
its so materialistic
anonymous
  • anonymous
you can help out with security if a hacker hacks, or you can hack a system down if they want to ^_^, hacking is not bad if you don't mis-use it :)
anonymous
  • anonymous
it is bad, if you use it badly :)
anonymous
  • anonymous
that is what I tell everyone
anonymous
  • anonymous
I dont use it for evil materialistic gains, I dont steal ppls money and info
anonymous
  • anonymous
I just break into some company for the thrill of it, it is like an ultimate puzzle, to outsmart a security system, but once I get in, i NEVER steal info or do any harm
anonymous
  • anonymous
how were you guys highschool experience
anonymous
  • anonymous
few times I even took my time to write them anonymous letters and explain how they can fix up the security holes
anonymous
  • anonymous
hacking is not bad, they way you use it defines if it is being used properly or not, and you care about what ppl think? Listen, it's none of our business to know what ppl think of us, let them make their own judgements, it's their words and not ours, we are us and they are not in us, so they don't know who we are, but we do, that's why wenever get affected by the cruel words that surrounds us. When we're not affected we become successful and valuable to all beings. That's what makes us all special ^_^
anonymous
  • anonymous
the*
anonymous
  • anonymous
you have good intentions andy, remember that :)
anonymous
  • anonymous
and show ppl that you do ^_^
anonymous
  • anonymous
how were you guys highschool experience
anonymous
  • anonymous
my high school experiance was ok, just boring, I use to hate IT lessons
anonymous
  • anonymous
honestly, I had my dark years then bright years :)
anonymous
  • anonymous
because the teacher had no clue what he was talking about
anonymous
  • anonymous
ughh i hate im a loner but i know in the future im going to be somebody
anonymous
  • anonymous
I used to dislike math and physics, but they are my passion right now . I refused to use the methods they used for teaching, same goes with chemistry.
anonymous
  • anonymous
don't say that word "hate" it's too powerful >_< , you'll be somebody, and you'll see martin :)
anonymous
  • anonymous
yes i know, people in my school thinks it cool to smoke and drink. HOw is taking your life away slowly cool?
anonymous
  • anonymous
has any of you read the Hacker Manifesto written by The Mentor? he wrote about his feeling in highshcool, as a hacker.
anonymous
  • anonymous
http://www.mithral.com/~beberg/manifesto.html
anonymous
  • anonymous
nope, then you do recognize their foolishness and understand it better than them to not think of it as cool martin :)
anonymous
  • anonymous
nope, but will check it now andy ^_^
anonymous
  • anonymous
yes i know, I dislike people who pick on other people. Its like leave them alone what are they doing to you. nothing.
anonymous
  • anonymous
^_^ I wish you the best of luck, both. I'm thinking of switching from IT college to Engineering. It's my passion and when this semester ends, I'll transfer :)
anonymous
  • anonymous
great
anonymous
  • anonymous
good luck
anonymous
  • anonymous
yep, thank you ^_^, but now I'll have to convince both my parents why I love engineering lol
anonymous
  • anonymous
well thanks for the help, igot to go it late school in 3 hours.
anonymous
  • anonymous
wait starica what do you do in engineering
anonymous
  • anonymous
what kind of engineering? Nanoengineering? BioEngineering? Mechanical engineering? any other type of eng?
anonymous
  • anonymous
They are all as different as ppl
anonymous
  • anonymous
martin how many years do you have until you graduate high school?
anonymous
  • anonymous
Chemical Engineering , and you are welcome martin ^_^
anonymous
  • anonymous
2 years
anonymous
  • anonymous
WOW, Chem Eng.... damn
anonymous
  • anonymous
I used to love it
anonymous
  • anonymous
especially explosiives making
anonymous
  • anonymous
lol, it's not abt making explosives, it's about creating new sources of energies that'll fight global warming and stop the depletion of the ozone layer and so much more ^_^
anonymous
  • anonymous
lucky me chemical stores only sell Potassium and Sodium to companies :) because i would have probably blown myself up already trying to make Astrolite
anonymous
  • anonymous
LOL! don't even think abt it andy . Control yourself =D
anonymous
  • anonymous
you used to love it? why? what happened?
anonymous
  • anonymous
well bye going to go study, thanks for helpiing me
anonymous
  • anonymous
I dont have time for it anymore, got lo love hacking even more....
anonymous
  • anonymous
ok, good luck martin
anonymous
  • anonymous
np and good luck martin :)!
anonymous
  • anonymous
I can't stop thinking about it, I'm all excited when someone opens a discussion abt it :)
anonymous
  • anonymous
I was forced to choose between something I love and something I need. I chose the thing I need, thought about it for a year, and I'm going back to follow what I love :)
anonymous
  • anonymous
oh, and if you want to save the planet, sstarica, why dont you study green energy production courses, well you know what I mean,
anonymous
  • anonymous
yep I do, I've been researching about the whole thing last year's summer :) before entering college.
anonymous
  • anonymous
isn't it physical/mechanical eng that deals with alternate/clean energy production?
anonymous
  • anonymous
I did that already, I've read abou all types of energies to have a background about the topic and got clear to what to do :)
anonymous
  • anonymous
like production of things like solar panels, wind turbines and so on
anonymous
  • anonymous
nope, it's chemical engineering :)
anonymous
  • anonymous
:o really??? wow, never knew it.... i just dont see how making an efficient wind turbine links to chemistry
anonymous
  • anonymous
Chemical Engineers develop and control processes in general. Since remediation and environmental treatment are processes, Chemical Engineers are actively involved. However, Chemical Engineers are also tackling the Environmental issues from a different angle, namely clean technology. That is to develop processes (and alternative products) that would not produce the pollutants from the first place, or at least improve the operation in order to reduce the produced pollutants. Beside that Chemical Engineers work in other operations not related to the environment.
anonymous
  • anonymous
ok, got it
anonymous
  • anonymous
that's the answer I got after asking a professor in college ^_^ he ahs helped me alot!
anonymous
  • anonymous
has*
anonymous
  • anonymous
oh, have you ever heard of Nikola Tesla?
anonymous
  • anonymous
hmm? nope, who is she?
anonymous
  • anonymous
:o He is the scientist because of whom we have wireless comunications, AC electricity, AC generators/motors, and hundreads of other things without which 21st century would not be as we know it (it would look more like 19th century)
anonymous
  • anonymous
wait, it's a guy LOL
anonymous
  • anonymous
that guy is a legend
anonymous
  • anonymous
googled him ^^" =P
anonymous
  • anonymous
from just being a village boy to a legend, how awesome is that?
anonymous
  • anonymous
he made some stuff in 1940s that scientists are not able to reproduce even now
anonymous
  • anonymous
it is pretty awesome
anonymous
  • anonymous
ever heard of Philadelphian experiment? LOL
anonymous
  • anonymous
lol, no, what is it? :)
anonymous
  • anonymous
googled it, something that had to do with military lol :)
anonymous
  • anonymous
omg, is it me or am I getting more and more attached to google nowadays? =D
anonymous
  • anonymous
wikipedia for more info, but in short, in 1943, an experiment that tried to make a ship inwisible
anonymous
  • anonymous
=D
anonymous
  • anonymous
LOL! I did check wikipedia
anonymous
  • anonymous
and, ppl that were in the ship during experiment, all became either insane or died, and some had some pretty bizare stories to tell of what happened there
anonymous
  • anonymous
you should read it some time it is interesting
anonymous
  • anonymous
I sure will :)
anonymous
  • anonymous
I havefavored both the manifesto and this experiment to read later :)
anonymous
  • anonymous
anyways, does your intelligent soul believe that there is such thing as multiple universes, time travel (LOL LOL LOL), and spiritual reality (another dimention?)
anonymous
  • anonymous
actually, you've brought up the topic I was thinking about yesterday :) and I have written a theory about it.
anonymous
  • anonymous
can you send it to me?
anonymous
  • anonymous
yet I need consultancy in proving my theory :)
anonymous
  • anonymous
be glad to
anonymous
  • anonymous
so, if you send it to me, I can see if I can find some logical problems... :) i used to study LOTS of metaphysics, quantum physics and theories like that... so..
anonymous
  • anonymous
I've sent it to a couple of professors in college , who work in the math field, but none could answer the question. I'm sending it ot my high school physics + maths teacher this sunday and see what he'll say :)
anonymous
  • anonymous
seriously!? oh this is GREAT andy! how can I send it to u?
anonymous
  • anonymous
he is one of the great ppl I've met in my life, a genius of his type :)
anonymous
  • anonymous
you can either upload the file to DARPA SAT 45 (one of the GPS sattelites I have access to and use as my file server, LOL), or you can send it to my email, which is naitreid@gmail.com
anonymous
  • anonymous
I'll choose the email, lol :)
anonymous
  • anonymous
when do you think you could send it?
anonymous
  • anonymous
now! you've got me excited :)
anonymous
  • anonymous
:)
anonymous
  • anonymous
^_^
anonymous
  • anonymous
did you get it? :)
anonymous
  • anonymous
yes
anonymous
  • anonymous
it's more about whether space is finite or infinite
anonymous
  • anonymous
got it
anonymous
  • anonymous
so, can I give you a HARSH and uncensored review?? :D
anonymous
  • anonymous
lol, I'll listen to any judgements :) and take it into consideration
anonymous
  • anonymous
oh, too bad but skydrive has removed your file
anonymous
  • anonymous
do you have it on your PC hd?
anonymous
  • anonymous
you didn't receive it?
anonymous
  • anonymous
ok, I think I know what happened
anonymous
  • anonymous
wait.
anonymous
  • anonymous
you did not attach a file itself, but only a link to it, but the link is to your personal file which is protected by your live pasword
anonymous
  • anonymous
oh hold on lol
anonymous
  • anonymous
done
anonymous
  • anonymous
ok, got it, :)
anonymous
  • anonymous
:) nice quick last moment touch before sending :)
anonymous
  • anonymous
what touch lol?
anonymous
  • anonymous
never mind... You mention Quaran there, are you muslim?
anonymous
  • anonymous
I'm kind of slow, did I mention that before? ^^" Yep :)
anonymous
  • anonymous
ok, another very important question, are you a true muslim, obiding ALL the rules and laws of Quran?
anonymous
  • anonymous
Lol, if I were not to obide the rules of the Quran and the rules by which the prophet has mentioned, then I'm not a muslim am I? Ofcourse I am.
anonymous
  • anonymous
well, many call themselfs Muslims, Budhists, Christians, and many other religions/movement's believers, but many of those many, do not fully follow, study, examine, and believe what is written in their scriptures. That is why I asked.
anonymous
  • anonymous
Now worries :) Those who don't go with the rules of their religions are those who have no religion at all. :)
anonymous
  • anonymous
no*
anonymous
  • anonymous
exactly, but religion is a very dangerous and usually wrongly interpreted and understood word
anonymous
  • anonymous
that's why people have made up different religions, doesn't that get you curious?
anonymous
  • anonymous
well, I it VERY hard to fully determine which religion is the true one, VERY hard
anonymous
  • anonymous
I'm not praising my religion, but the Quran is the book that beholds God's words of how he created the universe and Earth in 6 days, how life began in earth, mentioned the diseases and their cures, relationships between a husband and wife , politcal polices, everything. People , scientists and scholars have found answers to mysterious questions now, but the Quran had the answer almost 2000 years ago :) If you read it , you'll understand what I'm talking abt ^_^
anonymous
  • anonymous
all of your questions, have answers in that book and they make sense. I myself was taken aback :)
anonymous
  • anonymous
well, I read many scriptures like Quran, Bible and others.... ALL of them have answers to many question in life... that is not enough to prove the religion the right and only one. I think the only way we can 100% know if the religion we follow is correct is by experiancing a supernatural happening.
anonymous
  • anonymous
I agree ^_^
anonymous
  • anonymous
There are stories about people who have faced the worse in life, you can read about and also, the prohpet's sayings that existed more than 1,400 years :)
anonymous
  • anonymous
anyway, I will carefully read your theory, and will send a response to you to the same email, but just to start, the including of religious facts/beliefs should not be mixed with science. Why? Because you believe in it but other scientist do not. Also, because scriptures simply give a statement about something, like "The universe is spherical..." but it does nothing to explain why that statement is correct, even if it is correct.
anonymous
  • anonymous
does it make any sense?
anonymous
  • anonymous
That's why I've mentioned the predictions of other scientists :) if you have noticed.
anonymous
  • anonymous
like perelam who proved hirbel's work?
anonymous
  • anonymous
hope I have spelled his name correctly ^^"
anonymous
  • anonymous
or he won't forgive me lol
anonymous
  • anonymous
Perelman proved the Hilbert's work *
anonymous
  • anonymous
:), yes I know, but still, i don't see how quran will help your theory to get accepted. You could simply add that piece of info at the very bottom, list it as a text that also predicted/stated that universe is sperical.
anonymous
  • anonymous
Quran is another proof to support my theory. That's why I have put 3 and not only 1. You can exclude the one that has Quran and move on reading lol :)
anonymous
  • anonymous
ok, =D, i will move on, (btw there is a great difference between proof and suggestion, Quran, nor any other holy text, can NOT ever prove ANYTHING unless, it is proven to be true itself, which it hasn't, like any other religion, since religion can not be proven physically), ok i am moving on
anonymous
  • anonymous
lol, okay okay I GOT YOU =D :) silly
anonymous
  • anonymous
I'll hit the showers now ^_^
anonymous
  • anonymous
ok, I will checkout the rest of the letter and tell you if I find any other logical problems (just personal opinions of course)
anonymous
  • anonymous
sure, thank you ^_^
