## anonymous one year ago Use the table to determine the location with the greatest amount of rainfall and the location with the least amount of rainfall. a.Using complete sentences, identify the location with the greatest amount of rainfall and the location with the least amount of rainfall, and express the ratio of their respective rainfalls as a whole number. b. Describe what this ratio tells you. Needles, California 0.1173 m Mt. Waialeale, Hawai'i 11.4 m Puako, Hawai’i 25.6 cm Death Valley, California 57 mm Mojave, California 160 mm Hilo, Hawai'i 480 cm

1. Astrophysics

Can you upload a image for the question instead...you should pay attention to the units, know that meters (m) > centimetres (cm) > millimetres (mm)

2. Astrophysics

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?

3. Astrophysics

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. \[1m = 100 cm = 1000 mm\]

4. anonymous

I am trying to get an image now

5. Astrophysics

Ok

6. anonymous

7. Astrophysics

Ah so it wants it in meters as well, that's great :)

8. Astrophysics

Do you know how to put it in scientific notation?

9. anonymous

yes

10. Astrophysics

It's basically counting the amount of zeros, so if we have |dw:1435190922191:dw|

11. Astrophysics

Ok great :)

12. Astrophysics

So can you show me what the scientific notation is for 11.4m?

13. anonymous

4 x 11^1 ?

14. Astrophysics

Pay attention to the decimal spots, so we have |dw:1435191229915:dw|

15. Astrophysics

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

16. Astrophysics

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.

17. anonymous

Ok I am viewing it now

18. Astrophysics

19. anonymous

25.6 = 2.56 x 10^1

20. Astrophysics

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.

21. Astrophysics

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|

22. Astrophysics

That's how we convert it to meters, now we can put it in scientific notation

23. Astrophysics

So go ahead and write that in scientific notation

24. anonymous

0.256 x 10^-1

25. Astrophysics

So now we have 57mm, know how to convert that to meters? Note: 1m = 1000mm

26. Astrophysics

Do what I showed you above but with mm, and see what you get

27. anonymous

5.71 x 10^1

28. Astrophysics

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|

29. anonymous

I tried to post a drawing. is it 5.7 x 10^1

30. Astrophysics

No, please go over my drawing and what I've said.

31. anonymous

.57 x 10^1

32. Astrophysics

|dw:1435193272246:dw|

33. Astrophysics

Like I've said before, pay attention to the units.

34. Astrophysics

Now use unit conversion for the next one, 160mm to meters.

35. anonymous

160 mm = 1.6 x 10^2

36. Astrophysics

You're not listening to me :\, you have to convert it to meters (m) first. The answer they gave you is in millimetres (mm)

37. anonymous

0.16 x 10^1

38. Astrophysics

For scientific notation we use numbers between 1 to 10

39. Astrophysics

So it would be 1.6 x 10^(-1)

40. anonymous

4.8 x 10-1

41. Astrophysics

No, it's 480 centimetres this time not mm.

42. Astrophysics

So convert that into meters, remember 1m = 100 cm, here you have 480 cm.

43. Astrophysics

This one is a bit tricky for scientific notation, hint: we don't have to move the decimal at all (once you convert it)

44. anonymous

4.8 x 10^1

45. Astrophysics

Close, it's actually 4.8 x 10^0

46. Astrophysics

4.8 x 10^1 = 48

47. Astrophysics

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.

48. anonymous

That was tricky

49. Astrophysics

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!

50. anonymous

Pusko Hawaii

51. Astrophysics

|dw:1435195556539:dw| that look good, please check

52. Astrophysics

53. Astrophysics

Now which one is the greatest and which is the least

54. anonymous

Least: Death Valley California.....Greatest Mt. W. Hawaii

55. Astrophysics

Nice :)

56. Astrophysics

|dw:1435196178636:dw| just so we have it in the drawing

57. Astrophysics

Now the question wants a ratio for greatest/ least right?

58. Astrophysics

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!

59. anonymous

0.057/11.4= 0.005

60. Astrophysics

Can you post the full question, because above wants greatest/ least

61. Astrophysics

The answer also makes more sense if it's greatest/ least

62. anonymous

11.4/0.057 = 0.005

63. anonymous

Thank you for the help. : )

64. Astrophysics

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!).

65. Preetha

Good work explaining Astro! If your SS was a bit higher - we could use another Qualified Helper!

66. Astrophysics

Hey, thanks :)

67. TheSmartOne

So, I was helping someone with this same question, for the ratio part, I got confused too. But I read the question and it said "respectively" so the ratio of least to greatest, so 0.005 would be correct btw, nice work Astro <3
