Question

A family refers to a group of two or more people related by birth, marriage, or adoption who reside together. In 2000, in Country A, the average family net worth was $480,000 and there were about 8.3x10^7 families. Calculate the total family net worth in Country A in 2000.

Answer 1

Well, one family makes $480,000.
And if there are 8.3*10^7 families, that would move the decimal from 8.3 to:
83,000,000.
After you figure that out you would multiply that by $480,000 to figure out how much net work was in country A.

Answer 2

39,840,000,000,000 is the right answer or too many zeros?

Answer 8

Its all good, This is only my second year and things like this used to stump me as well,
Alright, (-4p)^2
Whats a negative squared?
A positive because a negative * a negative = a Positive,
So what's 4^2?
16,
Just add the varible p with it and you get
16p

Answer 9

you make it look so EASY! ..when I read the steps. :)

Answer 10

Haha, I know its a bit confusing but you'll get there, everyone does.

Answer 11

(9m)^-2 is my last one, so if I was to try it ...it would be
-18m?

Answer 12

oh...

Answer 13

-81m?

Answer 14

i think.. lol

Answer 15

Alright, Is that a negative 2 for an exponet?

Answer 16

yes

Answer 17

Alright, Haven't had to deal with a negative exponet in awhile, but that does look correct.
9 * -9 would = -81
It may be a positive 81 though because you're squaring a positive number.
But don't forget the m!
Not sure, but its either -81m or 81m
I'm thinking -81m
