height. If she can jump 87.72 inches, how
tall is she?

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

5/12

step-by-step explanation:

give them both a common denominator so you get 9/12 and 4/12. subtract 9/12 from 4/12 to get 5/12.
