Anna [14]

Given:

Total number of students = 1400

The ratio of boys to girls is 3 to 4 for the school.

To find:

The number of boys and girls.

Solution:

We have,  Boy : Girls = 3:4.

Let number of boys be 3x and number of girls be 4x.

Total number of students = 1400

3x+4x=1400

7x=1400

Divide both sides by 7.

x=200

Now,

Number of boys =3\times 200=600

Number of girls =4\times 200=800

Therefore, the number of boys is 600 and number of girls is 800 in the Berkmar Middle school.

7billion = 5 {e}^{15r} \\ 1.4billion =  {e}^{15r}  \\ ln(1.4 \: billion) = 15r \\ 21.0597 = 15r \\ r = 1.404

4) \\  t = 0  \: y= 200 \\200 = a {e}^{0}  \\ a = 200 \\ 800 = 200 {e}^{8k}  \\ 4 =  {e}^{8k}  \\ ln(4) = 8k \\ k = 0.1733
