The lengths of the legs of a right triangle are 7.5 inches and 10.0 inches. What is the length of the hypotenuse of this right triangle?

12.5 inches

Step-by-step explanation:

To find the hypotenuse of a right triangle, you have to use pythagoreans theorem, which is

a and b represent the length of the legs, and c represents the hypotenuse.

So, all we have to do is plug in the numbers 7.5 and 10 for the lengths of the legs, and we get this equation:

Just solve the equation, and you end up with a hypotenuse of length 12.5

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
