Before the new kids the ratio of girls to boys is 15:12 because there are 15 girls and 12 boys now you can simplify by dividing 15 by 3 and 12 by 3 to get 5:4 as your simplified ratio. As far as after the new kids. Since there is 1 new girl you do 15+1 to get 16 and there are 3 new boys so you do 12+3 to get 15 now 16:15 is already in simplest form so your answer is:
Before: 15:12 simplified as 5:4
After 16:15
Hope this helps.
Answer:
It is to represent the area of the park.
Step-by-step explanation:
The length and width of the park would be inches, miles, or meters to describe the linear aspect of the park.
If the park was, for example, 2 miles long and 3 miles wide, you would say the park is 6 miles squared. This is to describe the square area of the park. Square units could be replaced by squared acres, miles, or meters depending on the size of the park. This is to represent the area of the park.
The circumference of this circle to the nearest tenth is equal to 43.1 feet.
<u>Given the following data:</u>
To determine the circumference of this circle to the nearest tenth:
Mathematically, the circumference of a circle is given by the formula:

<u>Where:</u>
- C is the circumference of a circle.
- r is the radius of a circle.
Substituting the given parameters into the formula, we have;

Circumference = 43.1 feet.

Answer:
D) 0.35
Step-by-step explanation:
The table gives the area between z=0 and the given magnitude of z. That is, the area between z = 0 and z = -0.6 is 0.23, as found in the 0.6 column of the table. Similarly, the area between z = 0 and z = 0.3 is 0.12, as found in the 0.3 column of the table.
The area between z = -0.6 and z = +0.3 is the sum of these areas:
p(-.6<z<.3) = 0.23 +0.12 = 0.35
