What does this problem mean :)

It's asking about the unit rate.

Step-by-step explanation:

If she can by 8 gal. of gas for 28$, we need to know how much she spends on 1 gallon of gas. So simply divide 28 by 8. That number is how much it is per gallon. So then multiply the number you got by 9 and see if it is 30$. If not, it is false.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
