PLEASE HELP A conical tank, vertex down, is being filled with water a rate of 18pift^3/min. if the tank has a height of 30 ft and a radius of 15 ft at the widest point how fast is the water rising when it is 12 ft deep please show work!

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
