Answer:
36 Days!
Step-by-step explanation:
So A barrel contained 60 gallons of water. Water leaked out of the barrel at a rate of 5 gallons every 3 days. The question is “At this rate, how many days did it take for all 60 gallons of water to leak out of the barrel”? So What I did to find this out is multiplyed 3 by 12 to get 36 days. But When I was doing that I was also paying attention to that 5 gallons of water leak out of the barrel in 3 days, that’s why I multiplyed by 3.
If this doesn’t make sense to you I could explain it better if you need more explanation.
Hope This Helps!

Step-by-step explanation:
If she bought 3 of something that costed $8 then it would be 8 x 3
Using the mean concept, it is found that we will need 15 more points to bring up his average up to 90%.
The mean of a data-set is the <u>sum of all observations divided by the number of observations</u>.
In this problem:
- In the first 5 observations, total of 21 out of 25 points, hence the mean for these observations is
. - In the next n observations, mean of 1.
Hence, the mean is:
We want the mean to be of 0.9, thus:
3 more testes are need, each worth 5 points, hence, 15 more points are needed to bring up his average up to 90%.
