Answer:

It takes 2.5 minutes to fill the tank.

Explanation:

The net speed or net rate for filling the 10-liters tank is equal to the speed the tap is filling less the speed the water is leaking through the hole located at the bottom of the tank:

Net rate = rate of filling - rate of leaking

Net rate = 5 liters/minute - 1 liter/minute

Net rate = 4 liters/minute

Thus, consiedering the tank is empty at the beginning, the time is:

Time = Volume of the tank / net rate of filling

Time = 10 liters / (4liters/minute)

Time = 2.5 minutes ← answer

Azizah got 1 for the slope of the line through 2 points (1,2) and (4,-1). Explain to her the mistake she made and how to find th

ololo11 [35]

(1,2)(4,-1)
slope = (y2 - y1) / (x2 - x1)
slope = (-1 - 2) / (4 - 1) = -3/3 = -1

the slope is -1......I am not sure of the mistake.....unless she just added (-1 - 2) and got 3 instead of -3.......or when dividing -3/3....she maybe forgot about the negative sign
