3.2 * 3.4
multiply the baby weight by the multiplier
how do I leave it in form ab?
3.2 * 3.4 is ab
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
Thank you for your help
um... how many years in a decade?
so... \[3.4\times10\times365\times60~~~ is~the~answer~i~think~\]
Thank you! This is helping me a bunch
Can you show me how you got the numbers? I need to show all of my work
and then try to make it into sciencitific notation so it makes #.##*10^#
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
and i forgot the 24
okay, so first I do 24*365=8760 then I 8760*10=87600 Then 87600*140=12,264,000?
you forgot the 60 minutes
so I multiply the 60 minutes too? or just mention it?
no you have to multiply it, because then you have to take the result into scientific notation
Okay, so all I have to do is 60*24=1440 1440*365=525,600 525,600*10=5,256,000
um no not like that....
I wish I was better at math this is really confusing
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
okay, so 5,256,000*140=735,840,000
so the final answer is 735,840,000? Thank you!
It says put the answer in scientific notation. Do you know how to do that?
no, not really :/
so basicially... 321000000 turns into 3.21*10^8
Im still confused
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|
It moved 8 spaces left, so the exponent is 8|dw:1440736701759:dw|
okay, so 7,358,400,000?
no. 7,358,400,000 is decimal notation. They want the scientific notation above
Im confused, I dont really have a math brain
watch this for more information on scientific notation https://www.khanacademy.org/math/pre-algebra/exponents-radicals/scientific-notation/v/scientific-notation
okay, will do
\(7.3584 \times 10^8\) is scientific notation 7,358,400,000 is decimal notation two different ways of writing the exact same number
help me plzz
Oh okay, its just shorter
Thank you, sorry I took up so much of your time
