Answer:
B. The charge per kilowatt-hour.
Step-by-step explanation:
We have been given that an electric company charges a certain rate per kilowatt-hour of electricity used and an administrative fee of $3.50. The company charged Zhao $63.25 for using 800 kWh of electricity.
The equation represents the total amount of bill charged by electricity comapany to Zhao for 800 kilowatts of electricity use.
Since total bill is $63.25, administrative fee is $3.50 and total use of electricity is 800 kilowatts, therefore, r represents the charge per kilowatt hour and option B is the correct choice.
Answer:
Total Area = 68
Step-by-step explanation:
Comment
There is 1 square at each end.
There are 2 congruent trapezoids in the middle
Draw a 7 inch line across the widest part of the middle
Area of the squares
Area = s^2
s = 3
Area = 3^2
Area = 9
But there are 2 of them 18
Area of the 2 trapezoids
Area = (b1 + b2)*h / 2
b1 = 3
b2 = 7 Notice that 7 was the line you drew
h = 5
Area = (3 + 7)*5/2
Area = 50 / 2
Area = 25
But there are 2 of them <u> 50</u>
Total Area 68
First part is Southwest. Easiest thing is to look at a map.
