I would say its A but I'm not 100%
Answer:
0.2
Step-by-step explanation:
11,15,19,23
an = 11 + 4(n-1)
an = 11 + 4n - 4
an = 4n + 7
The increase of volume = volume of the cube = 1 cubic foot = 1728 cu ins
Area of the base = 12 sq ft = 12 * 144 = 1728 sq ins
The height of increase = 1728 / 1728 = 1 inch Answer
N = 13/20 or 0.65
25.5n - 3 = 5.5n + 10
Add 3 to both sides of the equation.
25.5n = 5.5n + 13
Subtract 5.5n from both sides.
20n = 13
Divide both sides by 20.
n = 13/20 or 0.65
