So firstly, you're gonna replace the T variable with 2.2, which is the time given to us. And so the equation is gonna look like this:
![2.2=2*3.14* \sqrt{ \frac{L}{32} }](https://tex.z-dn.net/?f=2.2%3D2%2A3.14%2A%20%5Csqrt%7B%20%5Cfrac%7BL%7D%7B32%7D%20%7D%20)
and we will be solving for L.
The next thing you wanna do multiply 2 and 3.14 together, so your equation should look like this:
![2.2=6.28* \sqrt{ \frac{L}{32} }](https://tex.z-dn.net/?f=2.2%3D6.28%2A%20%5Csqrt%7B%20%5Cfrac%7BL%7D%7B32%7D%20%7D%20)
After that, you're gonna want to square all the terms in this equation (2.2, 6.28, and
![\sqrt{ \frac{L}{32} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%5Cfrac%7BL%7D%7B32%7D%20%7D%20)
) to remove the square root. Your equation will look like this
![4.84=39.4384* \frac{L}{32}](https://tex.z-dn.net/?f=4.84%3D39.4384%2A%20%5Cfrac%7BL%7D%7B32%7D%20)
Next up is you're gonna multiply 32, the reciprocal of 1/32, on each side so that the equation looks like this
![154.88=39.4384*L](https://tex.z-dn.net/?f=154.88%3D39.4384%2AL)
After, you're gonna divide 39.4384 on each side, and your equation should end up at
![3.927=L](https://tex.z-dn.net/?f=3.927%3DL)
. And assuming from your options, they are gonna want you to round to the nearest whole number, so the best option is 4 feet.
A : B : C = 5 : 8 : 10
A+ B = 5x + 8x = 13x
13x - 10x = 60
3x = 60
x = 20
Total = 5x + 8x + 10x = 23x
23x = 23(20) = 460 <========= answer
