Can you upload a image for the question instead...you should pay attention to the units, know that meters (m) > centimetres (cm) > millimetres (mm)
So if you notice Mt. Waialeale, Hawaii it says 11.4m and assuming that is for greatest amount of rainfall that would be it. Do you get the idea?
We should convert them all to a certain unit, so maybe meters, or what ever you're most comfortable with. So you can get a clearer picture. \[1m = 100 cm = 1000 mm\]
I am trying to get an image now
Ah so it wants it in meters as well, that's great :)
Do you know how to put it in scientific notation?
It's basically counting the amount of zeros, so if we have |dw:1435190922191:dw|
Ok great :)
So can you show me what the scientific notation is for 11.4m?
4 x 11^1 ?
Pay attention to the decimal spots, so we have |dw:1435191229915:dw|
Does that make sense? https://www.khanacademy.org/math/pre-algebra/exponents-radicals/scientific-notation/v/scientific-notation use this site to learn scientific notation it will be able to explain it better than me
I think it's important you understand that first and we can move on then, we will have to convert the others to meters, so let me know whenever you're ready.
Ok I am viewing it now
Alright, take your time
25.6 = 2.56 x 10^1
That's right but wait a second, because notice that's in cm, not meters. We have to convert it to m first before we put it in scientific notation.
Remember as I showed above, there's 100 cm in 1 meter, so all we have to do is divide by 100 cm. |dw:1435191939372:dw|
That's how we convert it to meters, now we can put it in scientific notation
So go ahead and write that in scientific notation
0.256 x 10^-1
So now we have 57mm, know how to convert that to meters? Note: 1m = 1000mm
Do what I showed you above but with mm, and see what you get
5.71 x 10^1
Mhm, no that's not right, remember we have to convert it to meters first. It's in mm, those are different units than meters which is just m. |dw:1435192676440:dw|
I tried to post a drawing. is it 5.7 x 10^1
No, please go over my drawing and what I've said.
.57 x 10^1
Like I've said before, pay attention to the units.
Now use unit conversion for the next one, 160mm to meters.
160 mm = 1.6 x 10^2
You're not listening to me :\, you have to convert it to meters (m) first. The answer they gave you is in millimetres (mm)
0.16 x 10^1
For scientific notation we use numbers between 1 to 10
So it would be 1.6 x 10^(-1)
4.8 x 10-1
No, it's 480 centimetres this time not mm.
So convert that into meters, remember 1m = 100 cm, here you have 480 cm.
This one is a bit tricky for scientific notation, hint: we don't have to move the decimal at all (once you convert it)
4.8 x 10^1
Close, it's actually 4.8 x 10^0
4.8 x 10^1 = 48
Anything to the power of 0 is 1, so 4.8 x 10^0 = 4.8 since 10^0 = 1, I know it seems a bit silly, but that's how it works haha.
That was tricky
Lets put it in order now, so we can figure out which one has the greatest amount of rainfall and which has the least, and yes it was!
|dw:1435195556539:dw| that look good, please check
|dw:1435195796611:dw| maybe that will help you
Now which one is the greatest and which is the least
Least: Death Valley California.....Greatest Mt. W. Hawaii
|dw:1435196178636:dw| just so we have it in the drawing
Now the question wants a ratio for greatest/ least right?
So just make a ratio of it, you can use a calculator to divide/ long division, the questions are easy from here, since we now have the information :) so please try them and once you do post it here and I will check them for you!
Can you post the full question, because above wants greatest/ least
The answer also makes more sense if it's greatest/ least
11.4/0.057 = 0.005
Thank you for the help. : )
Np, but it says it wants a whole number right? So that means it has to be something like 1, 2, 3 etc...so we should get 11.4/0.057 = 200 (whole number) meaning the amount of rainfall in Mt. Walaleale is 200x more than in Death Valley, and makes sense, Death Valley is a very dry place if I recall right :P (name even says so!).
Good work explaining Astro! If your SS was a bit higher - we could use another Qualified Helper!
Hey, thanks :)
