We know the equation
gives the number of cups if we know the numbe rog gallons.
If we want an equation that gives the number of gallons if we know the number of cups we just have to solve hte equation for g, that is:
Therefore, the equation we are looking for is:
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
