To solve this problem, let's set up a proportion, letting x represent the unknown number of gallons the faucet loses in 48 hours.
5 gallons / 20 hours = x gallons / 48 hours
To solve this proportion, we are going to use cross-products. This is the products of numerator of one fraction and the denominator of the other fraction set equal to one another. It results in the equation:
5 * 48 = 20 * x
Next we simplify by performing the operations.
240 = 20x
Finally, we divide both sides by 20 to get x alone on the right side of the equation.
12=x
Therefore, 12 gallons of water will be lost in 48 hours.

an unknown amount of trumpeters.
the answer is 40.
Answer:
use pythagorean's theorem; x=6
Step-by-step explanation:
a^2 + b^2 = c^2
a=length; b(x)=height; c= hypotenuse (longest side)
8^2 + b^2 = 10^2
64 + b^2 = 100 (subtract 64 from each side)
b^2= 36
6 x 6 = 36 so b=6
x=6
Answer:
The answer is B.
