Answer: 1,800 ft.³
Step-by-step explanation: To find out how much water is needed to fill the pool, we need to find the volume of the pool. It's also important to understand that the swimming pool is a rectangular prism so we are finding the volume of a rectangular prism.
To find the volume of the pool, we use the formula shown.
<em>Volume = length × width × height </em>
Since the length of the pool is 20 feet, the width is 15 feet, and the depth or height is 6 feet we can plug this information into the formula.
Volume = (20 feet) (15 feet) (6 feet) = 1,800 ft.³
Therefore, it will take 1,800 cubic feet of water to fill the pool.
Multiply tvs sold by cost of the warranty:
17 x 20 = $340
Subtract the total warranty from total made and divide by number of TVs.
1360 - 340 = 1020
1020/17 = 60
He earns $60 per tv
Let suppose there are two functions that satisfy the equations
f ' +2f =0
and g' + 2g =0
If we add both of them
f' +g' + 2f + 2g =0
Grouping both the sides
(f+g) ' + 2 (f +g) =0So, if both g and f satisfies it then their sum also satisfy it, So there is a subspace and their sum satisfy them too.
