Answer:

162

Step-by-step explanation:

Note that you can split the given shape into a triangle and a rectangle.

Area of rectangle = base x height

base = 12

height = 9

Plug in the corresponding numbers into the corresponding variables:

Area of rectangle = 12 x 9

                             = 108

Area of triangle = (base x height)/2

base = 12

height = 9

Area of triangle = (12 x 9)/2

                          = (108)/2

                          = 54

Next, add the two areas together to get the full area:

108 + 54 = 162

162 is your answer.

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:

<h2>  2.11¢</h2>

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¢
