Your bill for a car repair is $166.50 The mechanic worked on your car for 15 hours What Is the hourly charge for labor? Set up the equation and solve

The hourly charge for labor is $11.10.

Step-by-step explanation:

Assuming there is no flat rate

166.50/15 = h

h represents the hourly charge

h = 11.10

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
