A scientist does an experiment with 12 plants he gives each plant exactly the same amount of water 1/5 liter how much water does he give the plants in all

If a scientist does an experiment where he puts 1/5 liters of water in 12 plants, and you want to see how much water he has put in all the plants together.

You would take 1/5 times 12

1/5*12=12/5

12/5 reduced would be 2 and 2/5 liters

2 and 2/5 liters of water in all plants

Hope this helps ;)

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)
