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.

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