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
Divide both sides by 7.
Now,
Number of boys
Number of girls
Therefore, the number of boys is 600 and number of girls is 800 in the Berkmar Middle school.

Step-by-step explanation:
A triangle with angles of 30-60-90 will always have sides that measure in the following proportions:
The side opposite the 30* angle = a
The side opposite the 60* angle =
The side opposite the 90* angle = 2a
(I used "a" here because your question uses "x" and I don't want to confuse things, but usually people use "x" rather than "a")
They gave us that the hypotenuse (the side opposite the 90* angle) is 10, from there we can figure out the other sides:
Since the side opposite 90* is 2a, and 2a = 10, divide 10 by 2 and you get a = 5.
Once we know what "a" is, we can fill in the rest:
30* = 5
60* =
90* = 10
