Answer:
8 ft
Step-by-step explanation:
the ladder will make a right angle triangle with the house. The hypotenuse of the triangle is the ladder, 20 ft, and the height of the triagnle is 18 ft.
Solve for the base of the right angle triangle using pythagorean's theorem:
c=20, a=18, b=?



round to the nearest foot,
b = 8 ft
First find 7% of 2,500 which is 175, then you add 175 plus 2,500 and you get 2675. So, Mr. Osmund paid $2,675 for his computer! Hope that helps!
All things being equal; demand decreases, as price increases.
The quantity supplied when price is $4 is 28
From table 4.4 (see attachment).
When price = $4, we have the following supplies:
- <em>Firm A = 6</em>
- <em>Firm B = 6</em>
- <em>Firm C = 8</em>
- <em>Firm D = 10</em>
<em />
So, the total supply at $4 is:


Hence, the quantity supplied when price is $4 is 28

y-intercept is -3 so it must pass the vertical line -3.
Now start from point (0,-3) and rise up by 3, then go right by 1 since the slope is 3/1 or 3.
It should look like this:
