Step-by-step explanation:
Answer:
20.05 kilowatt-hour
Step-by-step explanation:
Total electric bill = $84.21
Charges per kilowatt-hour = $0.14
Days in April = 30 days
Number of hours = x
Total electric bill = Charges per kilowatt-hour × Days in April × Number of hours
84.21 = 0.14 * 30 * x
84.21 = 4.2 * x
84.21 = 4.2x
Divide both sides by 4.2
x = 84.21 / 4.2
= 20.05
x = 20.05 kilowatt-hour
Therefore, Luke use 20.05 kilowatt-hour per day during the month of April

Step-by-step explanation:
The volume of the cube is 1
Answer:
No
Step-by-step explanation:
Given:
Volume of cone = 144 in³
Diameter of 12 inch
Find:
Volume of cylinder[Same height and radius] is 144 in³ or not
Computation:
Volume of cone = [1/3][π][r²][h]
144 = [1/3][3.14][(12/2)²][h]
144 = 37.68 h
Height of cone = 3.82
Volume of cylinder[Same height and radius] = [π][r²][h]
Volume of cylinder[Same height and radius] = [3.14][6²][3.82]
Volume of cylinder[Same height and radius] = 431.81
Volume of cylinder[Same height and radius] = 432 in³
So,
Volume of cylinder[Same height and radius] is not 144 in³
