how do I leave it in form ab?

- anonymous

3.2 * 3.4 is ab

- anonymous

oh okay, thank you!

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

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

- anonymous

Thank you for your help

- anonymous

um... how many years in a decade?

- anonymous

10

- anonymous

ok

- anonymous

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

- anonymous

Thank you! This is helping me a bunch

- anonymous

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

- anonymous

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

- anonymous

@Leong

- 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

- anonymous

oops sorry

- anonymous

and i forgot the 24

- anonymous

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

- anonymous

you forgot the 60 minutes

- anonymous

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

- anonymous

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

- anonymous

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

- anonymous

um no not like that....

- anonymous

I wish I was better at math this is really confusing

- 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

- anonymous

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

- anonymous

yes

- anonymous

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

- anonymous

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

- anonymous

no, not really :/

- anonymous

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

- anonymous

Im still confused

- 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|

- anonymous

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

- anonymous

okay, so 7,358,400,000?

- anonymous

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

- anonymous

Im confused, I dont really have a math brain

- anonymous

watch this for more information on scientific notation
https://www.khanacademy.org/math/pre-algebra/exponents-radicals/scientific-notation/v/scientific-notation

- anonymous

okay, will do

- 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

- anonymous

help me plzz

- anonymous

Oh okay, its just shorter

- anonymous

yes

- anonymous

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

- anonymous

no problem
