Samantha is creating concrete spheres for a weight-lifting competition. One of the spheres needs to have a weight of 350 pounds.
loris [4]

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

What is the slope of the line passing through the points (0, 4) and (-8, -1)?
Bas_tet [7]

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
