Answer:

A, D

Step-by-step explanation:

When we multiply the fractions, we can get:

$\frac{1}{5^{4} }$

This is also equivalent to:

$5^{-4}$

When looking at the answer choices, the only ones that equal $5^{-4}$ are A and D because:

$(5^{-2})^{2} =5^{-4}$

$5^{2}*5^{-6} = 5^{-4}$

Mr. Vestas sells electricity from a wind turbine to his local utility. He receives 3¢ per kilowatt hour for the first 500 kilowa

Grace [21]

Answer:

Step-by-step explanation:

We are expected to solve the weighted average price per kilowatt hour.

Step one:

The formula is

W =∑wX/∑w

W=weighted average

w=weights applied to x values

X=data values to be averaged

Step two:

given the total killowatt hour is 1800

the 1st = 500 at 3¢

2nd= 1000 at 2¢

3rd = (1800-1000+500) at 1¢ =(1800-1500) at 1¢ = (300) at 1¢

Step two:

Substituting into the expression we have

W =(500*3)+(1000*2)+(300*1)/500+1000+300

W=1500+2000+300/1800

W=3800/1800

W=2.11¢

The average price per kilowatt hour the utility paid to Mr. Vestas last month is 2.11¢
