12R - 4W ≥ 400

Step-by-step explanation:

If he get R correct will get 12R points

if he get w wrong will loss 4w points

so when she answered w+ r answers she will get 12R - 4W points

12R - 4W ≥ 400

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
