Answer:
D
Step-by-step explanation:
you get 150 by taking the product of 50 and 3, this eliminates answers 'a' and 'b'
since the question states the cost per mile driven is $1.50 and 'x' represents miles driven, D is the answer
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:
The complement is 50 and the supplement is 140
Step-by-step explanation:
Complementary angles add up to 90. Supplementary angles add up to 180. We simply need to subtract to find the difference to fill the gap.
90-40=50
180-40=140
The complement is 50 and the supplement is 140

Answer:
4
Step-by-step explanation:
Written in standard form, the quadratic is ...
x^2 -2x -3 = 0
This can be factored as ...
(x -3)(x +1) = 0
so the solutions are ...
x = 3, x = -1 . . . . . . values of x that make the factors zero
The difference of interest is ...
3 -(-1) = 4
Answer:
I believe The first one is 1.5 and the second one is 12
Step-by-step explanation:
3 divided by two is 1.5
If we multiply 1 by 1.5 we get 1.5
If we multiply 8 by 1.5 we get 12
