## anonymous one year ago THE DECIMALS ARE ACTUALLY NEGATIVE EXPONENTS HELP PLEASE??? The weight of a newborn baby chicken weighs 3.2 pounds. If an adult chicken can weigh up to 3.4 times more than a newborn chicken, how much does an adult chicken weigh? Leave your answer in the form ab.

1. anonymous

3.2 * 3.4

2. anonymous

10.88

3. anonymous

multiply the baby weight by the multiplier

4. anonymous

how do I leave it in form ab?

5. anonymous

3.2 * 3.4 is ab

6. anonymous

oh okay, thank you!

7. anonymous

Can you help me with another @peachpi I cant ask another question without verifying me email and I dont have time

8. anonymous

keep going i'm watching

The world population is increasing about 140 people per minute! At this rate, how much will the population increase in a decade? Put your answer in Scientific Notation. SHOW ALL OF YOUR WORK, THIS INCLUDES USING NUMBERS AND WORDS! Put your answer in Scientific Notation

10. anonymous

11. anonymous

um... how many years in a decade?

12. anonymous

10

13. anonymous

ok

14. anonymous

so... $3.4\times10\times365\times60~~~ is~the~answer~i~think~$

15. anonymous

Thank you! This is helping me a bunch

16. anonymous

Can you show me how you got the numbers? I need to show all of my work

17. anonymous

and then try to make it into sciencitific notation so it makes #.##*10^#

18. anonymous

@Leong

19. anonymous

right idea, but you missed a conversion. and I think the 3.4 is for the previous problem. you basically need to find the amount of minutes in a decade and then multiply by 140. 60 minutes in an hour 24 hours in a day 365 day in a year 10 years in a decade

20. anonymous

oops sorry

21. anonymous

and i forgot the 24

22. anonymous

okay, so first I do 24*365=8760 then I 8760*10=87600 Then 87600*140=12,264,000?

23. anonymous

you forgot the 60 minutes

24. anonymous

so I multiply the 60 minutes too? or just mention it?

25. anonymous

no you have to multiply it, because then you have to take the result into scientific notation

26. anonymous

Okay, so all I have to do is 60*24=1440 1440*365=525,600 525,600*10=5,256,000

27. anonymous

um no not like that....

28. anonymous

I wish I was better at math this is really confusing

29. anonymous

yes that's right. there are 5,256,000 minutes in a decade. Now multiply by 140 to find the population increase over the decade

30. anonymous

okay, so 5,256,000*140=735,840,000

31. anonymous

yes

32. anonymous

so the final answer is 735,840,000? Thank you!

33. anonymous

It says put the answer in scientific notation. Do you know how to do that?

34. anonymous

no, not really :/

35. anonymous

so basicially... 321000000 turns into 3.21*10^8

36. anonymous

Im still confused

37. anonymous

in scientific notation, the decimal needs to be behind the first number that's not 0. If the decimal point moves left, the exponent on 10 is positive. If it moves right the exponent on 10 is negative. The number of the exponent is the number of spaces the decimal moved|dw:1440736531983:dw|

38. anonymous

It moved 8 spaces left, so the exponent is 8|dw:1440736701759:dw|

39. anonymous

okay, so 7,358,400,000?

40. anonymous

no. 7,358,400,000 is decimal notation. They want the scientific notation above

41. anonymous

Im confused, I dont really have a math brain

42. anonymous

43. anonymous

okay, will do

44. anonymous

$$7.3584 \times 10^8$$ is scientific notation 7,358,400,000 is decimal notation two different ways of writing the exact same number

45. anonymous

help me plzz

46. anonymous

Oh okay, its just shorter

47. anonymous

yes

48. anonymous

Thank you, sorry I took up so much of your time

49. anonymous

no problem
