Area of a triangle = 1/2 x base x height

using the given information: area = 40 and base = 20

you now have 40 = 1/2 x 20 x height

divide both sides by 1/2

80 = 20 x height

divide both sides by 20

height = 80 / 20

height = 4 in.

Your electric bill has been as follows for the past six months:
kakasveta [241]

You want to find the monthly average over the past 6 months.


July: $78.56

August: $30.21

September: $81.20

October: $79.08

November: $66.18

December: $100.75


Add all of these up

(July) $78.56

(August) $30.21

(September) $81.20

(October) $79.08

(November) $66.18

(December) + $100.75

----------------------------------------------

(Total cost) $435.88


There are 6 months you are calculating for, therefore divide the total (combined) cost of 6 months with the total number of months (in this case, 6)


$435.88 (total cost of 6 months) ÷ 6 (months)


The average cost per month of over the past 6 months is $72.66.
