Answer: 15
Step-by-step explanation:
By the trapezoid midsegment theorem,

Step-by-step explanation:
The equation is given by :
63.25=800r+3.50
Here,
63.25 is the electric company charges
3.5 is an administrative fee
800 is charge per kilowatt hours
r is rate per kilowatt hour
In this proble, we need to tell that what does r represents. Hence, r shows kilowatt per hour.
We can solve it as follows :
63.25-3.5=800r+3.50-3.50 (Subtracting 3.50 to the both sides)
59.75=800r

Step-by-step explanation:
The tax rate is $3.78/$100 assessed

Cancel the $100 assessed.
612 × $3.78 = $2313.40
Angela's real estate tax will be 
(3a^4 * b^-2) * (2a^7 * b^-1)
= 6*a^(4+7)*b^(-2-1)
= 6*a^11*b^-3
