(Note that water weighs 8.345 pounds per gallon). a. Define a formula that determines the weight of the water that has drained from the tub, h, in terms of the number of gallons of water that have drained from the tub, g h 8.34 Preview b. 9. Preview syntax error: this is not an equation c. How much does the tub weigh when there is no water in the tub? Preview d. If the weight of the tub and water is 566.935 pounds, how many gallons of water are in the tub? Preview

Explanation / Answer

a)

h=8.345g

b)

w=875.7-h

=>w=875.7-8.345g

c)

weight of tub with no water = 875.7-(8.345*60)

=>weight of tub with no water = 375 pounds

d)

amount of water in tub = 60-g

w = 566.935

=>875.7-8.345g=566.935

=>8.345g=875.7-566.935

=>g=37

=>amount of water in tub = 60-37

=>amount of water in tub = 23 gallons
