Answer:
16 minutes
Step-by-step explanation:
If it takes 63 minutes to paint 9 walls then it means for every wall, it takes 63/9=7 minutes
Since it is 4 people working for 7 mins, the individual rate is 4/7 minutes per person
When we have 7 people, then the number minutes they take will be 7*4/7=4 minutes per wall
4 min per wall for 4 walls then total time will be 4*4=16 minutes
Answer:
G, the second option
Step-by-step explanation:
A triangle's degrees all adds up to 180.
45 + 60= 105 degrees
180-105= 75 degrees
<u>that in which makes </u><u>z=75 degrees.</u>
Since z is sharing a straight angle, which is 180 degrees
180-75= 105 degrees.
<u>Therefore, </u><u>w=105 degrees</u>

Answer:
6 months
Step-by-step explanation:
Gym1
12 + 20m
Gym2
22m
Set them equal
12 +20m = 22m
Subtract 20 m from each side
12 +20m-20m = 22m-20m
12 = 2m
Divide by 2
12/2 = 2m/2
6 =m
