We are given the electricity cost as 5 cents per
kilowatt-hour. We should notice that the cost is actually in the form of:
electrical cost = cost / (power * time)
Therefore to get a number which is in terms of cents
alone (cost alone), therefore we should multiply the given electrical cost
value with the power and time.
Power = 80 watt = 0.08 kilowatt
Time = 24 hours
Therefore the cost is calculated as:
cost = electrical cost * power * time
cost = [5 cents / (kilowatt hour)] (0.08 kilowatt) (24
hour)
cost = 9.6 cents
Answer:

Answer:
X=2y-6
Step-by-step explanation:
Y = 1/2 X+3
Y = X/2+3
Y = X+2•3/2
Y = X+6/2
2y = X+6
2y + (-6) = (X+6) + (-6)
2y-6 = X+6-6
2y-6 = X
Answer: X = 2y-6 I hope it helps....
Answer: 161, 25,-10,-31,-32,-301
Step-by-step explanation:
Answer:
Step-by-step explanation:
The -intercept of a line is the value when . In the equation , we can solve for its equation when we plug in .
Solving for when :
.
So the -intercept of the equation is .
To find what equation has the same -intercept, we can do the same process for each equations given by the choices. However, I can see that the equation, , has the -intercept. If in doubt, you can check for the solution below or solve each equations for yourself.
Solving for when :
Answer:
No.
Step-by-step explanation:
The whole numbers are 0, 1, 2, 3, ... (3/4)^2 is 9/16, which is not a whole number.
