The bill for a person who uses 560 kWh in a month is (d) $74
<h3>How to determine the bill?</h3>
The function is given as:
- b(x) = 0.15x; x ≤ 360
- b(x) = 0.10(x - 360) + 54; x > 360
For a person who uses 560 kWh, it means that:
x > 360
So, we use the following function to determine the bill
b(x) = 0.10(x - 360) + 54
Substitute 560 for x
b(560) = 0.10(560 - 360) + 54
Evaluate
b(560) = 74
Hence, the bill for a person who uses 560 kWh in a month is (d) $74

Answer: average time in minutes that it will take to drive from campus to workplace
Step-by-step explanation:
The dependent variable refers to the variable that the researcher is testing or measuring in an experiment. Let's say for example, we want to know the impact of reading on the examination score of a student. In this case, the dependent variable will be the examination score of the student since that's what we're measuring.
With regards to the question, the dependent variable is average time in minutes that it will take to drive from campus to workplace.
2a) if 1 ft³ weighs 150 lb==>the TOTAL VOLUME =5,000/150 =33.334 ft³
2b) 1 ft³ 1,728 in³. So the TOTAL volume in in³ =33.334 x 1728 = 57,600 in³
c) Volume =(1/3)(πR²).H but R = H then V= (1/3)(πR³).plug V (=57600)
57,600 = 1/3 (πR³) ==> R³ = (3 x 57600) / π ==> R = 38 in
d) Area x thickness = Volume ==> Area x 2 in = 57600 in then:
Are =57600/2 & Area =28,800 in²
Answer:
The answer is 85
Step-by-step explanation:
The equation used to find the sum of an arithmetic series is: (n/2) * (a1 + an).
n in this case is 10 (the number of numbers in the series)
an is 22 (plug in 10 to the expression 3n-8)
and a1 is -5 (plug in 1 to the expression 3n-8)
so when you plug everything in to the final equation, you get
(10/2) * (-5 + 22)
5 * 17
85
