Answer: (-3,6)

Step-by-step explanation:

We know that the standard equation a circle is given by ":-

(x-h)^2+(y-k)^2=r^2, where r is the center of the circle and (h,k) is the center of the circle.

The given equation of the circle : (x +3)^2+ (y - 6)^2 = 24

which is equivalent to (x -(-3))^2 + (y - 6)^2 = 24

It implies the coordinates of the center of the given circle =(-3,6)

There are 7 girls and 9 boys on a playground.
Anon25 [30]

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:

  • Ratio  = 7 : 16
