13. a robot can complete 8 tasks in 5/6 hour. each task takes the same amount
of time.
a. how long does it take the robot to complete one task?

b. how many tasks can the robot complete in one hour?

5/6 x 60 minutes = 50

Step-by-step explanation:

50/8 = 6.25 minutes per task

60/6.25 = 9 tasks with some left over minutes

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
