Let h be the height. Then:
1/2  (22h)=7500
22h=15000
h=15000/22=681.8181 yds

Catherine has $54. She plans to spend more than $20 of the money for a painting canvas. The rest will go toward paints. Each tub
Serga [27]

Answer;

4 or more tubes or paint.

Step-by-step explanation:

54- 8.50x > 20

-54               -54

 

-8.50x > -34

now you have to divide by -8.50 on both sides to get x alone.

-8.50x/-8.50 > -34/-8.50

x=4

Two pipes are used to fill a 300-gallon tub with water. The wide pipe can fill the tub in x hours. The narrow pipe can fill the
Hoochie [10]

Answer:

\frac{6}{x}-\frac{7}{y}=\frac{7}{12}

Step-by-step explanation:

#We know that the filling taps will run for a cumulative 4hrs each while the draining hole will empty for a combined 7hrs.

Let x be the rate of the first filling tap, and 2x of the 2nd filling tap and y be the rate of the hole.

#The rate at which the tub fills per hour is :

V_{tub}=\frac{1}{x}+\frac{1}{2x}-\frac{1}{y}\\\\=\frac{1}{x}(1+\frac{1}{2})-\frac{1}{y}\\\\=\frac{3}{2x}-\frac{1}{y}

#The volume of the tub at the instant moment the leak is repaired is expressed as:

V_{tub}=\frac{3}{2x}t_1-\frac{1}{y}t_2=\frac{7}{12}, \ \ \ \ \ \ t_1=4,t_2=7\\\\\\\frac{3}{2x}\times 4-\frac{1}{y}\times7\frac{7}{12}\\\\\\\frac{6}{x}-\frac{7}{y}=\frac{7}{12}

Hence, the volume of the tub after the leak is repaired is expressed as \frac{6}{x}-\frac{7}{y}=\frac{7}{12}
