The population is the amount of people, so there would be \[1.3*10^4\] people. Which is the same as 130000.

  • anonymous
Should I divide or subtract since its asking how many "more" people are there in algeville ?
skullpatrol
  • skullpatrol
subtract to find the difference between the two populations

@skullpatrol since its subtracting scientific notation it would be 5.6×10³ - 1.3×10⁴ ?
skullpatrol
  • skullpatrol
yes
anonymous
  • anonymous
You should subtract 1.3×10⁴-5.6×10³
skullpatrol
  • skullpatrol
but change the numbers so they are easier to work with

Can you handle it from here?

@skullpatrol I never actually thought of doing that until now because at schooll my math teachers taught me to move the decimal which makes the exponent decrease by one for example instead of 1.3 it would be 13. Because the decimal is moved to right then you would subtract 1 from the ³
skullpatrol
  • skullpatrol
yes you can do it that way too :-)

I subtracted 130000-56000 and I got 7400

@skull patrol since it's a word problem my answer would be - "there is 7,400 more people in algeville than Mathville" ?
skullpatrol
  • skullpatrol

Thanks for asking :-)

@skullpatrol can you help me with one more problem ?

\[1.3*10^4-5.6*10*3=1.3*10*10^3-5.6*10^3=\left( 1.3*10-5.6 \right)*10^3\] \[=\left( 13.0-5.6 \right)*10^3=7.4*10^3=\frac{ 74 }{ 10 }*1000=7400\]

@skullpatrol can you help me with this one ~ total health care costs in the United states in 2003 was $1.3 trillion . The U.S population was $290.9 million . What was the average amount spent per person on helthcare ?
skullpatrol
  • skullpatrol
Any ideas?
anonymous
  • anonymous
Sorry typo i meant 290.9 million
skullpatrol
  • skullpatrol
I see np :-)
anonymous
  • anonymous
I was thinking of turning 1.7 to 17,000,000,000,000
skullpatrol
  • skullpatrol
What does " the average amount spent per person on healthcare" mean to you?
anonymous
  • anonymous
Um I think it means like the the amount spent on each person
skullpatrol
  • skullpatrol
|dw:1442761950976:dw|
anonymous
  • anonymous
So it would be 1.7 trillion ÷ 290.9
skullpatrol
  • skullpatrol
Yes, but you missed the million on 290.9 million
skullpatrol
  • skullpatrol
Also a trillion is $$\Huge 10^{12}$$
skullpatrol
  • skullpatrol
|dw:1442762338080:dw|
anonymous
  • anonymous
Alrighty so it would be 290.9×10^6 ÷ 1.3 × 10^11 ?
skullpatrol
  • skullpatrol
10^12
anonymous
  • anonymous
Yeah 10^12 my bad
skullpatrol
  • skullpatrol
np
anonymous
  • anonymous
When I divided 290.9 by 1.3 I got 223.769231
skullpatrol
  • skullpatrol
yes
anonymous
  • anonymous
But isn't it too large ?
skullpatrol
  • skullpatrol
nope
anonymous
  • anonymous
Kk so when I subtracted my exponents I got -6
skullpatrol
  • skullpatrol
|dw:1442762966778:dw|
skullpatrol
  • skullpatrol
check the word "trillion"
anonymous
  • anonymous
Alrighty so the average person payed $223 ?
anonymous
  • anonymous
Wait isn't the 290.9 supposed to be on top ?
anonymous
  • anonymous
Are you there @skullpatrol?
skullpatrol
  • skullpatrol
you want dollars per person
anonymous
  • anonymous
Yeah so it's $223 per person or $23.30 ?
skullpatrol
  • skullpatrol
what about the powers of 10?
anonymous
  • anonymous
223×10^-6 because 6-12 = -6
anonymous
  • anonymous
I got it now
anonymous
  • anonymous
Thanks again @skullpatrol
