Answer:
The number of pipes to be cut from total length of pipe is 10 pipes
Step-by-step explanation:
Given as :
Total length of pipe = l = 7 foot
i.e ' = foot
The length of pipe to be cut = l' = foot
Let The number of pipes to be cut = n pipes
<u>According to question</u>
The number of pipes to be cut =
i.e n =
Or, n =
Or, n =
or, n = 5 × 2
∴ n = 10 pipes
So, The number of pipes to be cut = n = 10 pipes
Hence, The number of pipes to be cut from total length of pipe is 10 pipes Answer
