The exterior angle is equal to the 2 remote interior angles. For example, #7 is 80 degrees because the two remote angles(54 and 26) added together equal 80 degrees. Also, #9 would be 100 because the exterior angle is given to you. Since the 2 remote angles equal the exterior, all you do is 158+58=100
It would take 93.33 hours to use 14 kilowatt hours of electricity.
Step-by-step explanation:
Given,
Electricity used in one hour = 3/20 kilowatt hours
Ratio of time to electricity = 1 : 3/20
Let,
x be the number of hours to use 14 kilowatt hours electricity.
Ratio of time to electricity = x : 14
Using proportion;
Ratio of time to electricity :: Ratio of time to electricity
Product of mean = Product of extreme
Multiplying both sides by 20/3
It would take 93.33 hours to use 14 kilowatt hours of electricity.

PVAO=820[(1-(1+0.05/2)^(-2*14))/(0.05/2)]
PVAO=16371.21
If you multiply the number of students times 8 you get 96, but if you multiply the students by 8 you need to multiply the adults by 8 as well. Which leaves you with 16 adults. Is there more to this equation? I feel like this is only part of it.
