Open pipe fills a storage pool in 24 hours A second pipe feels the same pool in 12 hours when a third pipe is added and all three are used to fill the pool it takes only six hours Find how long it takes the third pipe to do the same job

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
