To find out how long it will take to clean each fish tank, we can use the formula:
Time = Amount of water / Rate of emptying
For the clownfish tank:
Initial amount of water = 175 gallons
Rate of emptying = 15 gallons per minute
Time = 175 / 15
Time = 11.67 minutes
So, it will take approximately 11.67 minutes to clean the clownfish tank.
For the red lionfish tank:
The equation representing the amount of water in the tank is:
y = 145.75 – 35.5x
We need to find out when the tank will be completely empty, in other words, when y = 0:
0 = 145.75 – 35.5x
35.5x = 145.75
x = 145.75 / 35.5
x ≈ 4.11
So, it will take approximately 4.11 minutes to clean the red lionfish tank.
Marco works at an aquarium shop. He is asked to clean two fish tanks. The clownfish tank begins with 175 gallons and empties at a rate of 15 gallons per minute. The amount of water in the red lionfish tank is represented by the equation y = 145.75 – 35.5x, where x is the number of minutes the pump has been emptying the tank.
