There is no such thing as a "kilowatt per hour". If that's actually what the question says, then it's a defective question, and you should put it away before it makes you any more confused.
A 120 watt light bulb uses exactly 0.12 kilowatt when it's turned on.
In one hour, it uses
(0.12 kilowatt) x (1 hour) = 0.12 kilowatt-hour of energy.
If energy costs $0.20 per kilowatt-hour, then the cost is
(0.12) x (0.20) = 2.4 cents. (0.024 dollar)
Here is the solution:
0.59 * 10 = $5.90
0.99 * 5 = $4.95
$5.90 - $4.95 = $0.95
You would save 0.95$ if you bought
10 candy bars at the sale price
rather than at the regular price. I am hoping that this answer has
satisfied your query and it will be able to help you in your endeavor, and if
you would like, feel free to ask another question.

Answer:
51 square units
Step-by-step explanation:
Area of a parallelogram = base x height
⇒ area = 4 x 3 = 12 square units
Area of a rectangle = width x length
width = √(2² + 3²) = √13
length = √(9² + 6²) = √117
area = √13 x √117 = 39 square units
Total area = 12 + 39 = 51 square units
Answer:
n = 2
Step-by-step explanation:
Given
(n - 4) - 3 = 3 - (2n + 3)
Multiply through by 2 to clear the fraction
n - 4 - 6 = 6 - 2(2n + 3) ← distribute
n - 10 = 6 - 4n - 6 ( add 4n to both sides )
5n - 10 = 0 ( add 10 to both sides )
5n = 10 ( divide both sides by 5 )
n = 2
