Area = 18 = 1/2 x 6 x (h+1)
h=5
Answer:
5.54 feet.
Step-by-step explanation:
Let h be the height of the pool and r be the radius of the pool.
We have been given that volume of cylindrical pool in Sunny Days Apartment building is 1200 cubic feet.
We have been given that the radius of the pool is 1.5 times its height. We can represent this information in an equation as:
Substituting equation (1) in volume formula we will get,
Substituting the given volume of pool in formula we will get,
Let us divide both sides of our equation by 2.25 pi.
Let us take cube root of both sides of our equation.
Therefore, the height of the pool is approximately 5.54 feet.
Answer:
40 miles
Step-by-step explanation:
Let's set <em>x</em> to the number of miles driven, and <em>t</em> to the number of hours it took to drive.
We know that 40<em>t</em> is equal to <em>x</em>.
We also know that 40<em>t</em> is equal to 30(<em>t</em> + 1/3).
Solve for t:
40t = 30(t+1/3)
40t = 30t + 10
Subtract 30t from both sides:
10t = 10
Divide 10 from both sides:
t = 1
40t = 40 x 1 = 40 miles
