Answer:
The school C shows the greatest rate of change between male and female students
Step-by-step explanation:
Let
x -----> the number of female students
y ----> the number of male students
we know that
The ratio of male students to female students is
we have
<em>School A</em>
<em>School B</em>
----> the slope of the linear equation
<em>School C</em>
so
therefore
The school C shows the greatest rate of change between male and female students
Answer:
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
we have
----> the radius is half the diameter
substitute the values
From the given information, we get the value of ABC = 120°.
<h3>How to estimate the value of ABC?</h3>
Given: In the figure, O exists the center of the circle and OABC exists as a parallelogram.
Now, the radius of the circle exists
OA = OB = OC
Opposite sides of a parallelogram are equal
AB = OC and OA = BC
In ∆OAB,
OA = OB = AB and,
In ∆OCB,
OC = OB = BC
Therefore, ∆OAB and ∆OCB exist in equilateral triangles.
All angles of an equilateral triangle are equivalent to 60°.
Hence, ∠ABC = ∠OBA + ∠OBC
∠ABC = 60° + 60°
∠ABC = 120°
Therefore, the value of ∠ABC = 120°.
