It takes 42 minutes for 6 people to paint 7 walls
<em><u>Solution:</u></em>
It takes 54 minutes for 4 people to paint 6 walls
To find: Minutes required for 6 people to paint 7 walls
If 
men can do 
work in 
days working 
hours per day and 
men can do 
work in 
days working 
hours per day, then
M = Number of men
D = Number of days
H = Number of hours per day
W = Amount of work
Here in this sum,
<em><u>54 minutes for 4 people to paint 6 walls</u></em>
<em><u>Minutes required for 6 people to paint 7 walls</u></em>
<em><u>Substituting the values in formula, we get</u></em>
Thus it takes 42 minutes for 6 people to paint 7 walls
I feel like it would be mean or median, because there is no outlier, making it so that all of the numbers are closely put together.
Put the set into order.
25, 26, 27, 28, 29
So, we know that this is all in order, making it so that we know for sure that there is no outlier.
If you find the mean, it'll represent the data nicely.
We know that both the mean and median represent the data set nicely, because it just does. It's one of those things that are extremely painful and hard to fully explain and have someone understand, but don't worry, it makes sense.
So, it can't just be the mean only or the median only.
It also can't be the mode only, because THERE IS NO MODE!
So, our final answer is mean or median :)

The Lewis family and the Perry family each used their sprinklers last summer. The water output rate for the Lewis family's sprinkler was 15 L per hour. The water output rate for the Perry family's sprinkler was 40 L per hour. The families used their sprinklers for a combined total of 65 hours, resulting in a total water output of 1850 L . How long was each sprinkler used
Answer:
Hours of use of sprinkler by Lewis family is 30 hours.
Hours of use of sprinkler by Perry family is 35 hours.
Step-by-step explanation:
Let W = hours of use by Lewis family
65 - W = hours of use by Perry family
Then;
15W + 40*(65 - W) = 1850
15W + 2600 - 40W = 1850
(15 - 40)W = 1850 - 2600
-25W = −750
W = 750/25 = 30
Therefore;
W = 30
65 - W = 65 - 30 = 35
Hence,
Hours of use by Lewis family is 30 hours.
Hours of use by Perry family is 35 hours.
