You need to spackle a hole on the outside of your house that is 24 feet off the
ground. You want to place the bottom of your ladder 7 feet from the wall. How tall
does the ladder need to be to reach the hole?
OA) 23 ft
OB) 25 ft
OC) 14 ft
QD) 20ft

The ladder needs to be 25 ft tall

Step-by-step explanation:

You can use the pythagorean theorem for this:

a²+b²=c²

a = 7, b = 24, c = ?

We need to solve for c:

7²+24²=c²

49+576=c²

c²=625

c=25

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.
