- <em>It takes</em><u> 2.5 minutes </u><em>to fill the tank.</em>
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
Answer:
3) 4x² -1
Step-by-step explanation:
A quadratic equation is a 2nd-degree polynomial equation.
1) an exponential equation (the variable is in the exponent)
2) a cubic equation (degree = 3)
3) a quadratic equation
4) a linear equation (degree = 1)
Recall the relation:
8 oz =1 cup
so,
1 oz = 18cup
Therefore,
16 oz = 168cup
= 2 cups
Hence, she should measure 2 cups to get 16 oz.
Answer:
the answer is yes hope this helps you
