below is a data table showing the amount of water remaining in a swimming pool. find and interpret the rate of change.

40 gallons per second

Step-by-step explanation:

every second, a set number of gallons is emptied from the pool. to find this amount, you essentially have to subtract the one number From one on top of it. Example: 300 - 260 = 40

You can either stop there or continue until you are confident you have the right answer

300 - 260 = 40

260 - 220 = 40

220 - 180 = 40

180 - 140 = 40

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

if e is the midpoint of bd, then bd is 14.
