Which solid has exactly five of planes of symmetry?

  Square Prism

Step-by-step explanation:

The cone has infinitely many planes of symmetry through its axis.

The Square Pyramid has 4 planes of symmetry, each one intersecting the apex and one of the 4 lines of symmetry of the square base.

The (isosceles) Triangular Prism has a plane of symmetry through the altitudes of each triangular face, and another bisecting and perpendicular to the long edges. (2 planes total)

The Square Prism has 4 planes of symmetry through the lines of symmetry of each square end (each of those planes contains the corresponding lines in both faces, so is perpendicular to the square end). It has a 5th plane of symmetry that bisects all of the long edges of the prism (and is parallel to the square ends). (5 planes total)

The Square Prism

Step-by-step explanation:

See attached graphic.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

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.
