In this situation, you have to use the equation
T = 2π√L / 32
We need to find L so we have:
T / 2π = √L / 32
(T / 2π) ^ 2 = L / 32
L = 32 * (T / 2π) ^ 2
Substitute the values:
L = 32 * (8.72 / (2 * (3.14))) ^ 2
L = 61.69694511 feet
L = 62 feet
So the Answer is
L = 62 feet
If 476 miles equates to 14 gallons, to find the gallons needed for 578 miles, you multiply 578 * 14 which is 8092, then divide that by 476 = 17
17 gallons of gas.
<h3><u>The variable x is equal to (p + 11)/5.</u></h3>
P = 5x - 11
<em><u>Add 11 to both sides.</u></em>
p + 11 = 5x
<em><u>Divide both sides by 5.</u></em>
(p + 11)/5 = x
So for this one all you have to do is find the average. Simply do 25 divided by 2 to get 12.5 miles per hour.
