Alright, so for AB and CD to be parallel, CX and DX would have to be equal, as is with AX and BX. In addition, for CD and AB to be parallel, all sides in both triangles are either equal or not all sides in even one triangle are equal. Therefore, CD is not 3. In addition, two sides of a triangle combined must be greater than the third, so that leaves 5, 4, and 2 for CD. If it was 5, that would mean that all sides are equal, so that leaves 4 and 2. However, I don't see anything to prove either one right, sorry:/

How many 3/4 foot lengths of pipe can be cut from a 7 and 1/2 foot pipe?
stiks02 [169]

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\frac{1}{2} foot

i.e ' = \frac{15}{2}  foot

The length of pipe to be cut = l' = \dfrac{3}{4} foot

Let The number of pipes to be cut = n pipes

<u>According to question</u>

The number of pipes to be cut = \dfrac{\textrm Total length of pipe}{Length of pipe to be cut}

i.e n = \dfrac{l}{l'}

Or, n = \frac{\frac{15}{2}}{\frac{3}{4}}

Or, n = \frac{15\times 4}{3\times 2}

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
