Answer:
Step-by-step explanation:
One pump will fill 200l in 20 minutes
So the rate of filling per pump will be 10l/minute (200/20)
Let the number of minutes it will take to fill the 600l be x minutes
Now, since the rate of filling per pump is 10 l/minute
Then in x minute, they would have filled 10l/minute * x = 10x liters
So it is now this 10x liters that will be equal to 600
To find x, we simply divide
10x = 600
x= 600/10
x = 6 minutes
Answer:
1st box in justification is going to be subtraction property.
2nd box is multiplication property.
1 box in steps is going to be (2/3y)=-6
2nd box in steps (2/3y)*(3/2)=-6(3/2)
3rd box in steps y=-9
Step-by-step explanation:
you're basically trying to solve for y. trying to get it by it self.
if you want me to explain it further down, you can tell me.
and I hope that helped
Answer:
y=7x-6
Step-by-step explanation:
Use point-slope equation.
y-y1=m(x-x1)
y-8=7(x-2)
y-8=7x-14
y=7x-6
YWU ---> S (each time two letters down!)
BDF go two up, but they don't ask you about that. Nice problem!
Step-by-step explanation:
r=11cm
x=3.14
area of a circle =xr^2
3.14(11)^2
379.94
379.9cm^2
