Question

This question... help me and you'll be rewarded with a metal and a side of fries

Answer 1

Brian is creating a collage on a piece of cardboard that has an area of 120r3 square centimeters. The collage is covered entirely by pieces of paper that do not overlap. Each piece has an area of sqrt(r^5) square centimeters. Use the given information to determine an expression for the total number of pieces of paper used.

Answer 2

i think you need to compute
\[120 r^3\div \sqrt{r^5}\]

Answer 3

or
\[\frac{120r^3}{\sqrt{r^5}}\]

Answer 4

if i read it correctly
start with
\[\sqrt{r^5}=r^2\sqrt{r}\]

Answer 5

they really reach for these word problems, don't they?

Answer 6

can i have pepper on the fries?

Answer 7

Yes, thank you! I understand it. It looks like I was right up until dividing which I have to remember :)

Answer 8

yw

Answer 9

WAIT. Don't forget your fries!

Answer 10

ooh pepper and mayo!!

Answer 11

;)

Answer 12

oh crap, i have to give the fries back, i made a mistake!
there is no 2 in the denominator, so it is just
\[120r\sqrt{r}\]

Answer 13

let me try this again

Answer 14

\[\frac{120r^3}{\sqrt{r^5}}=\frac{120r^3}{r^2\sqrt{r}}\]
\[=\frac{120r}{\sqrt{r}}=120\sqrt{r}\]
that's better!

Answer 15

i have no idea where i got the 2 from, it was just a dumb mistake on my part

Answer 16

Its fine, thank you and at least you caught it :)

Answer 17
