Answer:
Step-by-step explanation:
Assuming each person gets the same amount of work done, each wall in the first scenario takes 8 minutes to paint. If 3 people paint 4 walls, then each person is painting 1 1/3 of a wall. We can use that to find out how long it takes one person to paint 1 1/3 walls:
. Interpreting that, it takes each person 10 2/3 minutes to paint 1 1/3 walls.
If 4 people paint 7 walls, that means that each person is painting 7/4 walls, or 1.75 walls each. Using the fact that it takes 10.66666 minutes to paint 1.33333 walls, we can find out how many minutes it will take to paint 1.75 walls:
Cross multiply to get
18.666655 = 1.3333x so
x = 14.000 minutes
Y / (-25) = -100. Mult. both sides by -25, we get y = 2500 (answer)
since 1.5 is half of 3.0 all ouj havr t o do is multiply by 2 2.4*2=4.8 answer
Answer. Mass is a measurement of how much matter is in an object; weight is a measurement of how hard gravity is pulling on that object.
