Answer:
A=73
B=107
Step-by-step explanation:
since the angles are across from eachother they would be the same, the total angle of all 4 added together would be 360, and 73+107 would be 180, so 180+180 is equal to 360
remember that when total value is used a negative number is turned positive so it equals to 282 feet

y=-5/2x+3
Step-by-step explanation:
Answer:
d = 13.8 feet
Step-by-step explanation:
Because we are talking about cubic feet of water, we need the formula for the VOLUME of a cylinder. That formula is
![V=\pi r^2h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2h)
We will use 3.141592654 for pi; if the tank HALF filled with water is at 20 feet, then the height of the tank is 40 feet, so h = 40; and the volume it can hold in total is 6000 cubic feet. Filling in then gives us:
![6000=(3.141592654)(r^2)(40)](https://tex.z-dn.net/?f=6000%3D%283.141592654%29%28r%5E2%29%2840%29)
Simplify on the right to get
![6000=125.6637061r^2](https://tex.z-dn.net/?f=6000%3D125.6637061r%5E2)
Divide both sides by 125.6637061 to get that
![r^2=47.74648294](https://tex.z-dn.net/?f=r%5E2%3D47.74648294)
Taking the square root of both sides gives you
r = 6.90988299
But the diameter is twice the radius, so multiply that r value by 2 to get that the diameter to the nearest tenth of a foot is 13.8
