Answer:
It will take 2.5 minutes to reach 27 gallon .
Step-by-step explanation:
He is filling it at a rate of 6 gallon per minute
suppose it takes x minutes to reach 27 gallon
water filled in x minutes =
water already present + volume of water at the rate of 6 in x minutes
12 gallons + 6 gallon . minute 8 x minutes
12 + 6x
This should be equal to atleast 27
12+ 6x = 27
let us subtract 12 from both sides
6x = 27-12
6x = 15
divide both sides by 6
x= 2.5
Answer
It will take 2.5 minutes to reach 27 gallon .
When He start to fill the water
Answer: 2.10
Step-by-step explanation: 2.10 * 4 + 6
Answer:
(3, 2)
Step-by-step explanation:
y = 3x - 7
2x + 5y = 16
Solve for x:
2x + 5(3x - 7) = 16
2x + 15x - 35 = 16
17x = 51
x = 3
Solve for y:
y = 3(3) - 7
y = 9 - 7
y = 2
Answer:
(3, 2)
Answer:
1.
Step-by-step explanation:
I am assuming you want to simplify this.
cos^2 x + sin^2 x = 1 and
csc^2 x = 1 + cot^2 x so csc^2x - cot^2 x = 1
So the answer is 1/1 = 1.
