there are 4 red and 9 total you can pick 4 red total and that means 4/9 is the ratio

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

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
