Help and i will give brainiest if you answer them all if random will report

The equation for finding CoP is y=kx.

We know what k is. Since 'k' stands for constant, the Cop must be 36.

(Let c be how much Sophie spent, and m be the price of the car rental.)

Sophie paid for one half of the car rental, represented by 0.5m

Sophie also pays $25 for gasoline, represented by 25

By combining all of these you find how much Sophie spent, represented by c

I hope this helps, let me know if you have any questions about my response. Have a good rest of your day, and good luck with the rest of your work!

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

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
