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.
Answer:
Option 3
Step-by-step explanation:
All equations are in slope-intercept form.
The 'm' is the slope.
The 'b' is the y-intercept.
The slope is also known as the rate of change. So, we would have to look at what replaces 'm' and select two equations that have the same rate of change.
<em>Let's look over the equations:</em>
<h3>Equation A:</h3>In this equation, 0.3 replaces 'm', so the rate of change for this equation is 0.3.
<h3>Equation B:</h3>In this equation, 3 replaces 'm', so the rate of change for this equation is 3.
<h3>Equation C:</h3><h3>In this equation, 0.3 replaces 'm', so the rate of change for this equation is 0.3.
<h3>Equation D:</h3><h3>In this equation, 0.03 replaces 'm', so the rate of change for this equation is 0.03.
Equation C and equation A have 0.3 as the slope. Since the question asks for two equations that have the same rate of change, the answer would be Equations A and C, or Option 3.
