Other answers:

which ones do you need help on?
um, all of them except number one on page b
do you know the formula for the area of a square?
no,i dont remember
l x w = a, remember? but for a square, since the length and width are equal, you can just say s^2 = a
Ohhh.
yes. i was wondering however about the problems at the top of page b
oooh i misread what you said. sorry, i'm tired
its alright
tnx for taking a look

so 7^2 + 2^2 = ?
is that no one on page b?
yea. number 1, page b
thanks:)
do you know what the answer is? or what you think the answer is?
yup,7.2
about
ehh, i'd put 7.3 unless your teacher asked you not to round?
well, i am allowed to use a calc, and it said 7.2......
7.2801..., that's why i said 7.3, but put 7.2 if you want :)
ill put 7.3:)
ok, another one i need urgent help on
number two on page b
mmk, which one is that?
and then, number two on page a., plus number three on page a
my most urgent four.

but i doubt it
since ur tired
we're doign the same thing as the other one i posted
1 Attachment
doing*
whic one is that?
that's number 4 on page a
so 13^2 + 12^2 = ?
well, 11.48 144
155.48?
remember Pythagorean theorem... a^2 + b^2 = c^2 so 13^2 + 12^2 = c^2 169 + 144 = c^2
oh
313 = c^2, so what does c equal?
are a and b aleeady squared?
o square 313
right, so what's the square of 313?
9769
from google cqlculator
i meant square root, sorry
o
i entered '313^2' into the search engine
yea, i know what you did, but this is what you need to do: \[\sqrt{313}\]
ohhh duh. *hits own face*
17.69
yup
yay:) *writes*
thatd be which 1?
that was 4 on page a
tnx,and http://assets.openstudy.com/updates/attachments/5088ba01e4b0524190915d7e-aripotta-1351139613752-capture4.png ?
that was what you used to get the answer to number 4
Ari, srry, im having trouble with number 2
o
ok
tnx:)

Ari, the one you just hlped me on, was that the one withbthencoordinate points listed or the one about george?
so the hypotenuse is 17...do you see how i got the the lenght of the one leg?
and tnx
with the coordinates listed
tnx,let me look at ur most recent snapshot
ok.mcan you explain what x is?
yea, i was just asking you if you knew how i got 15 for the length of the one side? because if you know this, you can basically do any question similar to this
oh.no. how?
did you notice how the area of that square was 225? how can we find the side length of a square?
sq root oof area
yep, and that's how we got 15, does that make sense?
15
yes,ma'am
so if we know the hypotenuse is 17, and a leg is 15...how can we go about finding the other leg length?
15+x=17?
what's the Pythagorean theorem?
a^2+b^2=c^2
15^2+b^2=17^2?
yep
yay so i solve?
if you know how to. show me what you think you do
3.8-4.1
you're doing the square root again!
ii mean the other way around
don't! lol
srry :s im addicted to sqnroots i think
lol
er,sobhow then?
what's 15^2?
oooh 225
and what's 17^2?
289
right, so 225 + b^2 = 289. what do we do now?
subtract
289-225
=64
so b^2 = 64...what does b equal?
8
yep
:0 lol all that for 8
yea lol
tnx:)
ok, so one more
the one after this one
3 on page a?
yes
i think all you have to do for that is \[\sqrt{89}\]
it has answer choices
i know, what's the square root of 89?
9.43
9.43 matches which answer choice...?
d:0
yup
one more and tnx so much!
argh i thought that was our last one lol
plz explain what to do on number two
2 on page a?
i thought we already did that one?
yes
rlly?
i lostmtrack,whatnwasn it?
i believe it was 8, remember?
u knw which one im talking about?
yea...2 on page a? we already did it?
i lost track. k then,tnx so much!!!
that's it then?
not rlly, but i suppose thats all i mcan get help on,so...
wll, you should be able to do it by yourself now. how about you try to do one by yourself, and i'll check
well*
which one
whichever one we didn't do already and that you feel comfortable doing
umm..let me c
6 pg b
doing it...
"as the crow flies" i have no idea what that means lol
oh wait! that's the hypotenuse!
same:0
the hypotenuse is your answer
oh
explain plz?
well crows can fly over water and stuff. we'd have to walk around it. so "as the crow flies" is through the water or whatever, so it's the hypotenuse
ok.tnx the kms i just draw on the plane?
him going south then east?
south is down, east is right
ok,so i draw that and thats it?
the hypotenuse, c, is the answer
