Hel pleas A robot can complete 4 tasks in 10/3
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?

a. 3 hours and a half

b. wont be able to finish 1 task

Step-by-step explanation:

Robot will take  hour to complete each task.

The robot can complete  tasks in one hour.

Step-by-step explanation

We have been given that a robot can complete 8 tasks in 3/10 hour. Each task takes the same amount of time.

To find the time taken by robot to complete each task we will divide total time taken to complete 8 tasks by 8 as:

Now we will convert division problem into multiplication problem by flipping the 2nd fraction.

Therefore, robot will take  hour to complete each task.

To find tasks completed by robot in one hour we will use proportions.

Therefore, the robot can complete  tasks in one hour.

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
