One pump can fill a swimming pool in 6 hours. A second pipe drains the pool in 9 hours. If the the pool starts empty, what part of the pool will be filled if the first pipe works for 5 hours and the second pipe works for 6 hours.

1/6

Step-by-step explanation:

5/6=150/180

6/9=120/180

150/180 - 120/180 = 30/180

30/180=1/6

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

9 x 8 divided by (5-3)=36
