1. nick bought a large cube of cheese to feed his 100 rats. one side of the cube has an area of 16 square inches. what is the volume of the cube?

64

Step-by-step explanation:

The area of one side of a cube = s*s where s is the length of one of the sides.

s^2 = Area

Area = 16 which is given

s^2 = 16    take the square root of both sides.

sqrt(s^2) = sqrt(16)

s = 4

Volume = s^3

Volume = 4^3

Volume = 64 cu in

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
