The total number of students in rolled at Berkmar middle school is 1400 students the ratio of boys to girls is 3 to 4 for the school how many students are boys and how many students are girls at Berkmar Middle school

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

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
