The true answer is <span>t ≥ 49</span>
The part of the solution that is incorrect is (5). This is because -10 -8 = -18. :)
Solution-
Capacity of the spherical tank = 800 gallons.
1 gallon = 0.1337 ft³,
Volume of 800 gallons = 800 × 0.1337 = 106.96 ft³
Formula for the volume of sphere
Equating both the volumes
⇒ 
= 106.96
⇒ 
= 25.53
⇒ ![r = \sqrt[3]{25.53}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B3%5D%7B25.53%7D)
⇒ r = 2.94
∴ Radius of the sphere is 2.94 ft
37 and 29 won't work because these numbers are prime numbers, which can't be divided equally. This problem is basically saying which one of these are prime numbers.
548yds(3ft/yd)(mi/5280ft)=137/440 miles
You have a typo in your answers or maybe there is an E. none of the above :)
