1. The volume of an Olympic-size swimming pool is directly proportional to the cubic feet of water needed to fill the swimming pool. If 3 Olympic-size swimming pools need 270 000 cubic feet of water, how many cubic feet are needed to fill up 5 Olympic-size swimming pools?

If a fair 6 sided cube is rolled 60 times, theoretically how many times should you expect to roll a 4 or a 5?

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3
