Answer: 80 minutes
Step-by-step explanation:
Hi, to answer this question we have to write an equation for each tank:
An empty 1200 gallon tank is filled with water at a rate of 6 gallons of water per minute.
So, the amount of water of the tank is equal to the filling rate, 6 liters per minute (6m)
- Tank 1 =0 (empty )+ 6m =6m
The second 1200 gallon tank full of water is being drained at a rate of 9 gallons per minute.
So, the amount of water in the tank is equal to the amount of water already in the tank (1200 g), minus the draining rate (9m)
Since both tanks will have the same amount of water:
6m = 1200-9m
Solving for m (minutes):
6m+9m= 1200
15m = 1200
m= 1200/15
m= 80 minutes
Feel free to ask for more if needed or if you did not understand something.
Answer:
78
Step-by-step explanation:
X+y+z = 3063
y-79=x
z-376=y
z-455=x
z + (z-455)+ z-376 = 3063
3z-831= 3063
z = 1289
y = 913
x= 834
Answer:
the answer that 3.45 should be as a percent should be 345% because you mutliply 3.45 times 100 getting an answer of 345% and if you want to convert into a mixed number the percent 3 45/100 or simplified to 3 9/20 so hopefully that is the correct answer.
Step-by-step explanation: :DDDDDD hope this helps and mark me brainliest please.
