Answer:
It will take 4 hours and 48 minutes with both pipes.
Step-by-step explanation:
Add their rates of filling
1st pipe's rate = ( 1 tank ) / ( 12 hrs )
2nd pipe's rate = ( 1 tank ) / ( 8 hrs )
Let, t = hrs to fill tank using both pipes
(1 / 12) + (1 / 8) = (1 / t)
Multiply both sides by 24t
2t + 3t = 24
5t = 24
t = 4.8
0.8 x 60 = 48
It will take 4 hours and 48 minutes with both pipes
Answer:
2 / 5.
Step-by-step explanation:
The slope is the rise over the run.
In this case, the rise is 2 - (-6) = 2 + 6 = 8.
The run is 4 - (-16) = 4 + 16 = 20.
So, the slope is 8 / 20 = 4 / 10 = 2 / 5.
Hope this helps!
So then what is the problem u need help with? I'd be happy to help.
Answer:
slope = -1
Step-by-step explanation:
parallel lines have the same slope,
y = -x – 4
=> y = -1(x) -4
↑ slope
y = mx + b
↑ slope
