Answer:
Step-by-step explanation:
Since 15 liters of water flow through a water pipe and enter a tank within 4.5 minutes, the same amount of water would flow through a similar pipe at the same time. Therefore, if two similar water pipes are used, the volume of water that would flow into the tank in 4.5 minutes is 15 × 2 = 30 liters
Therefore, the time it will take to pump 727.5 liters of water into a water tank using 2 similar water pipes is
(727.5 × 4.5)/30 = 109.125 minutes
Step-by-step explanation:
parallelogram area is:h×base
10×14=140
we have two so
140×2=280
traingle is:h×base/2
18-10=8=h
8×14/2=56
56×3=168
168+280=448
36-9
-9+36
1 (36-9)
36-(3×3)
