We can draw this as:
We can use the Pythagorean theorem to find the length of the cable, as it is the hypotenuse of a right triangle:
![\begin{gathered} c^2=7^2+8^2 \\ c^2=49+64 \\ c^2=113 \\ c=\sqrt[]{113} \\ c\approx10.63 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20c%5E2%3D7%5E2%2B8%5E2%20%5C%5C%20c%5E2%3D49%2B64%20%5C%5C%20c%5E2%3D113%20%5C%5C%20c%3D%5Csqrt%5B%5D%7B113%7D%20%5C%5C%20c%5Capprox10.63%20%5Cend%7Bgathered%7D)
Answer: the cable length is 10.63 m.

Step-by-step explanation:
Answer:
12/5hours=2.4 hours
Step-by-step explanation:
Sam:6hours
Tom:4hours
This is a rate problem
Sam's rate is one job completed in 6 hours which is 1/6
Tom's rate is one job completed in 4 hours which is 1/4
Together, they could complete 1/4+1/6 of the job in y hours
We are trying to find the rate at which Sam and Tom could complete the job together, or one job in x days, for a rate of 1/y
1/4+1/6=1/y
The least common denominator is 12y
Multiplying through by the LCD which gives:
12y(1/4)+ 12y (1/6)= 12y (1/y)
3y + 2y=12
5y = 12
y=12/5 hours=2.4hours
Therefore it will take 12/5 hours or 2.4 hours to complete the job if they work together
