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.

4c^2-8c-1=0 complete the square round to nearest hundredth
olga55 [171]
Move constant to other side
add 1
4c^2-8c=1
divide by 4 to make leading coeficient 1
c^2-2c=1/4
take 1/2 of linear coeficient and square it
-2/2=-1, (-1)^2=1
add that to both sides
c^2-2c+1=1/4+1
factor perfect squaer and add
(c-1)^2=5/4
square root both sides
c-1=+/-(√5)/2
add 1
c=1+/-(√5)/2

c=2.12 or -0.12
