Me with this question. renee is making a scale diagram of her mp3 player. the length of her scale drawing is 8 inches, and the width is 14 inches. the actual length of the mp3 player is 4 centiimeters, and the width is 7 centimeters.

The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). the mean maximum oxygen uptake for elite athletes has been found to be 60 with a standard deviation of 7.2. assume that the distribution is approximately normal.

What percent of the circle below is shaded?

How do i start to solve? would appreciate a walk-thru! a bird sitting 16ft above the ground in an apple tree dislodges an apple. after how many seconds does the apple land on the ground? (assuming that no branches will interfere with it's fall)
