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:
<span>9.6 cents</span>
For this case we can make the following rule of three:
23000 -------> 100%
x --------------> 180%
Clearing the value of x we have:
x = (180/100) * (23000)
x = 41400
Answer:
you would expect about:
a) 41,400 responses
Hello!
To write the equation of the function y = x with a vertical compression by a factor of 1/4, we need to use the formula: y = a · x.
In this equation, y = a · x, a is the vertical compression/stretch. Since a = 1/4, we can substitute 1/4 for a.
Therefore, the answer is D, y = 1/4x.
Answer:
6 inches
Step-by-step explanation:
basically, first write an equation
2x^2 = x^2 + 5x + 6
then simplify this into
x^2 = 5x + 6
then use sum-product pattern and factor
(x - 6)(x + 1) = 0
then split into two equations
x - 6 = 0, x + 1 = 0
so, you have x = 6 and x = -1
because it can't be negative, 6 is your answer
Yes its correct you did well :)
