Answer:
Volume of cube = 2.33 cubic feet
Length of side of cube = 1.325 feet
Step-by-step explanation:
Given
Weight of each sphere = 350 pounds
Density of each concrete = 150 pounds per cubic foot
Volume of cube = 350 pounds / 150 pounds per cubic foot
Volume of cube = 350/150 cubic feet
Volume of cube = 2.33 cubic feet
Length of side of cube = Cubic root of 2.33
Length of side of cube = 1.325 feet

Answer:
0.625
Step-by-step explanation:
Given the points :
(0, 4) and (-8, -1)
x1 = 0 ; y1 = 4
x2 = - 8 ; y2 = - 1
Slope, m = rise / run
Rise = y2 - y1 = - 1 - 4 = - 5
Rise = x2 - x1 = - 8 - 0 = - 8
The slope, m = - 5 / - 8
Slope, m = 0.625
