Over the course of a year, the population of rats in Memphis increased from 350000 to 406000.
madreJ [45]
It is very important to look at all the details that are already given in the question. Only then the problem should be started for solving.
Initial population of Memphis = 350000
population of Memphis after 1 year = 406000
Then
Increase in population of Memphis in a year = 406000 - 350000
                                                                       = 56000
Then
Percentage increase in the
population of Memphis in a year = (56000/350000) * 100
                                                    = (56 * 10)/35
                                                    = 560/35
                                                    = 16 percent
So there is a 16% increase in the population of Memphis in a year.

Solve for y please I have no clue I am so lost thank you

In the Triangle ABD, Using Pythagoras theorem we can write

AB^2=BD^2+AD^2\\ \\ AB^2=9^2+y^2\\ \\ AB^2=81+y^2\\ \\

In the Triangle ACD using Pythagoras Theorem

AC^2=AD^2+CD^2\\ \\ AC^2=y^2+7^2\\ \\ AC^2=y^2+49\\

Now in the larger Triangle ABC, we can write

AB^2+AC^2=BC^2

Now substitute the values from the above equations we get

81+y^2+49+y^2=(9+7)^2\\ \\ 130+2y^2=16^2\\ \\ 130+2y^2=256\\ \\ 65+y^2=128\\ \\ y^2=128-65=63\\ \\ y=\sqrt{63} =3\sqrt{7} \\
