LUCKY_DIMON [66]
Answer:
job estimate = $60.1875

Explanation:
1- labor payment:
The hourly rate is $7.5 and the job will take around 2.5 hours. This means that:
labor payment = 7.2 * 2.5 = $18.75

2- Overhead value:
The overhead value is 85%.
This means that:
its cost would be = 85% * labor payment 
                           = 0.85 * 18.75 
                           = $15.9375

3- Retail cost:
We are given that the retail cost is $25.5

4- getting the job estimate:
job estimate = labor payment + overhead cost + retail
job estimate = 18.75 + 15.9375 + 25.5
job estimate = $60.1875

Hope this helps :)

If the lengths of the legs of a right triangle are 5 and 12, what is the length of the hypotenuse?
kondor19780726 [428]

Answer:

13

Step-by-step explanation:

If we have a right triangle, we can use the Pythagorean theorem to find the hypotenuse

a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

5^2 + 12^2 = c^2

25+144= c^2

169 = c^2

Take the square root of each side

sqrt(169) = sqrt(c^2)

13= c
