A little above 7. This can be seen because 7 squared is 49 and 8 squared is 64. With this being said 52 is closer to 49 rather than 64 so the square root of 52 is a little above 7.

Hope this helps.

At a shelter, 15% of dogs are puppies. There are 60 dogs at the shelter.How many are puppies?

Ostrovityanka [42]

It is important to look at all the information’s already given in the question. Those information’s will come in handy while solving the question.
Number of dogs in the shelter = 60
Percentage of puppies in the shelter = 15%
Then
Number of puppies in the shelter = (15/100) * 60
= 900/100
= 9
So there are a total of 9 puppies in the shelter. I hope the procedure is clear enough for you to understand. I am glad to have helped you.
