ILL GIVE BRAINLIEST. It’s simple I’m just dumb! If you could help thank you! (If you could explain too that’d be nice, you don’t have to though)

D

Step-by-step explanation:

There is only one variable in this situation which means you can rule out A and C, B is wrong because it said it wants Y, so D is your answer!

The answer would be 'D': y=6.5x

Step-by-step explanation:

Since y would be the total amount, it'd be weird if it was x=6.5y since the part would be more than the total. Plus, for every roll, it sells for $6.50, and when it multiplies by x (the amount sold) you would get y (the total).

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
