When estimating the number of spheres contained in a prism we should account for the empty space between the spheres. to do this we find 190% of the volume of the sphere and use that value in our estimation.
if gumballs have a 2 inch diameter, what should we use as the volume of each gumball in our calculation? (round your answer to the nearest tenth)
a. 4.2 cubic inches
b. 8.0 cubic inches
c. 33.5 cubic inches
d. 5280 cubic inches

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.
