Answer:
16 men would be needed to paint the room in 2 hours
Step-by-step explanation:
We can use proportion to solve the problem given, but first we need to determine whether it is a direct or indirect proportion.
If the number of men are increase, the time taken to do the work will decrease, If the number of men are decrease, the time taken to do the work will increase. Therefore, this is an indirect proportion.
We are going to arrange the data inversely.
Let x be the number of men needed to paint the room in two hours
8 hours = 2 hours
x = 4 men
Cross-multiply
2×x = 8×4
2x = 32
Divide both-side of the equation by 2
2x/2 = 32/2
x = 16 men
16 men would be needed to paint the room in 2 hours
Answer:
Answers are 3 AM ; 10 , 54
Step-by-step explanation:
We are given a graph.
Recording of temperature starts from 9 PM.
So from Graph,
Temperature ate 9 PM = 59°F
Temperature ate 11 PM = 54°F
Temperature ate 1 AM = 51°F
Temperature ate 3 AM = 50°F
Temperature ate 5 AM = 51°F
Temperature ate 7 AM = 54°F
Temperature ate 9 AM = 59°F
So, At 3 AM the water is at its lowest temperature.
and
After 10 hours passed, the temperature of the lake is 54°F.
Therefore, Answers are 3 AM ; 10 , 54
