82. The area required to keep 20 bees in a box is 4786 X 10 km. How much area will be required to keep 900 bees​

2 153 700 km

Step-by-step explanation:

Find how many boxes are needed for 900 bees.

900 ÷ 20 = 45 boxes

Find how much area of each box.

4786 x 10 = 47860

Find how much area are needed for 45 boxes.

step-by-step explanation:

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.
