A robot can complete 8 tasks in
3 and a fourth hour. Each task takes the same amount of time.

5/6 hour = 5/6 × 60 = 300/6 = 50 minutes

8 tasks in 50 minutes

1 task = 50/8 = 6 1/4 minutes

a. robot completes task in 6 1/4 minutes

b. #tasks per hour =

#of tasks × time takes to do task < or = 60

n × 6.25 = 60

6.25n = 60.

n= 60/6.25 = 9.6

robot can complete 9 tasks in one hour

Step-by-step explanation:

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
