The ratio of the number of girls to the total number of children is 7 : 16.
<h3>
Ratio is defined as follows:</h3>
- It is a comparison between two or more numbers that measures sizes in relation to each other
- It describe how much of a thing is compared to another.
The number of girls in the playground = 7
The number of boys in the playground = 9
The total number in the playground is the sum of the number of girls and the number of boys.
Therefore,
total children in the playground = 7 + 9 = 16
The ratio of the number of girls to the total number of children can be express as follows:

Answer:
Domain → (-∞, -1)∪(-1, ∞)
Range → (-∞, ∞)
Step-by-step explanation:
Given function is,
This function is not defined when the denominator is zero.
2x + 2 = 0
2x = -2
x = -1
Therefore, x = -1 is not in the domain of this function.
And the domain will be,
(-∞, -1)∪(-1, ∞)
For all values of x (except x = -1) we get some output values (value of 
).
Therefore, range of the function will be (-∞, ∞).
Circumference = r * 2 * pi
Circumference of track 1 is 376.8
A and F are true. because A is y=2x+7, and F is y=2x+7.
We know that the equation y=2x+7 has a point 0,7 and with the slope being 2, rise over run would make another point 1,9. And because these are linear equations if the equation y=2x+7 goes through 1,9 then it will go though -2,3 as well.
