A robot can complete 5 tasks in 2/3 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. 8 Minutes  

B. 7.5 Tasks

Step-by-step explanation:

A. Since 2/3 of an hour is 40 minutes. We can divide 40 by 5 to get the answer of 8 minutes per task.

B. An hour is 60 minutes. So 60 divided by 8 minutes would be 7.5 Tasks.

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
