Subtract 4 from both sides, y = 5
Answer:
62.8
Step-by-step explanation:
V = πr²h
V = 3.14 × 2² × 5
V = 3.14 × 4 × 5
V = 3.14 × 20
V = 62.8
Answer:
Option 1
Step-by-step explanation:
12x²+2x-4
2(6x²+x-2)
2(6x²+4x-3x-2)
2(2x(3x+2)-1(3x+2))
2(3x+2)(2x-1)
Our water faucet leaked 3 2/6 liters of water every 3/5 of a hour.
We are to find the rate in liter per hour at which the water faucet leaked.
First, use the number of liters the water faucet leaked in 3/5 of a hour.
This is 3 2/6 = 20/6
Therefore, the number of liters of water faucet leaked in 1 hour is
(20/6) / (3/5)
Before we solve this, we should simplify,
20/6 can be simplified to 10/3
3/5 cannot be simplified
Then, we should modify our problem to use reciprocation instead of a complex fraction,
(10 • 5) / (3 • 3)
This equals 50/9
Now, solve 50/9 for 5.555555555556
This rounds to 5.6
Thus, the required rate at which the water faucet leaked is 5.6 liters per hour.
