The cost to replace a water pump in a sports car was $483. This included $305 for the water pump and $89 per hour for labor. How many hours of labor were required to replace the water pump?

2 hours

Step-by-step explanation:

483-305(total cost - water pump cost) =179

179/89 (price per hour for labor) = 2

3

Step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
