If the longest wall in the living room is referring to the side that I have drawn over in white and red in the attached image, or if it is the leftmost wall, then that wall is 36 feet long. For every half inch, it is 6 feet, so because there are 6 'half inches' in 3, you multiply 6 feet by the 6 half inches there are, and get 36. There are simpler ways to solve it but I can't take a picture of my work, so I hope this helps. Good luck.

, Ohio in 1990, the number of residents has decreased by 5% every 5 years. In 1990, there were 182,000 residents in Dayton, Ohio

Answer:

133,787 residents

Step-by-step explanation:

First thing we need to do here is calculate the number of 5 years between 2020 and 1990

That would be 2020-1990 = 30/5 = 6

Now to estimate the present population, we will be needing an exponential equation

P = I(1-r)^n

where P is the present population at 2020

I is the population at 1990 which is 182,000

r is the percentage decrease every 5 years which is 5% or simply 5/100 = 0.05

n is the number of 5 years between 1990 and 2020 which is 6

Plugging all these values we have;

P = 182000(1-0.05)^6

P = 182000(0.95)^6

P = 133,786.724

To the nearest whole number, P = 133,787 residents
