Answer:

The midpoint is (5/2, -15/2)

Step-by-step explanation:

The x coordinate of the midpoint is the average of the x coordinates

(1+4)/2 = 5/2

The y coordinate of the midpoint is the average of the x coordinates

(1+-16)/2 = -15/2

The midpoint is (5/2, -15/2)

Answer:

The number of girl dogs are $42$

Step-by-step explanation:

The animal shelter only houses cats and dogs.

The proportion of cats = $\frac{9}{23}$

Therefore, the proportion of dogs = $\frac{14}{23}$

And $\frac{1}{4}$ of each animal type is a boy.

If there are 27 girl cats, that means 27 represents $\frac{3}{4}$ of the cat population.

So we can now find the number of boy cats in the shelter,

$\frac{27}{\frac{3}{4} }*\frac{1}{4}$

= $\frac{27*4}{3*4}$

= $\frac{27}{3}$

= $9$

So the total number of boy cats are 9.

Total number of cats = Number of girl cats + Number of Boy cats

= $27+9$

= $36$

36 cats represents $\frac{9}{23}$ proportion of the total animals.

Therefore, we can find the total number of dogs in the shelter,

$\frac{36}{\frac{9}{23} }*\frac{14}{23}$

= $\frac{36*23*14}{9*23}$

= $\frac{36*14}{9}$

= $\frac{4*14}{1}$

= $56$

So the total number of dogs are 56.

Out of this 56 $\frac{3}{4}$ of the dogs are girls.

Therefore,

The number of girl dogs = $56*\frac{3}{4}$

= $42$
