Dale and 2 friends share 1/4 of a cake. Each piece is the same size. Dale believes each piece of cake has an angle measure of 45 degree. Is sale correct explain

Dale is not correct (see the explanation)

Step-by-step explanation:

step 1

Divide 1/4 by 3 ( Dale and two friends)

step 2

we know that

The complete circle (cake) have a central angle of 360 degrees

Divide 360 degrees by 12

That means----> Each slice of 1/12 has an angle measure of 30 degrees

therefore

Dale is not correct

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.
