Answer:
The number of students in the school band = 70
40% of students in the school band are sixth graders.
20% of students in the school band are seventh graders.
We have to find the number of band members that are sixth graders.
The number of sixth graders in school band are:
![40\% of 70](https://tex.z-dn.net/?f=40%5C%25%20of%2070)
![0.40 \times 70](https://tex.z-dn.net/?f=0.40%20%5Ctimes%2070)
![28](https://tex.z-dn.net/?f=28)
Therefore, there are 28 band members that are sixth graders.
The transformation that can be used to show that ABCDE and its image are congruent is a 90° counterclockwise.
<h3>How to depict the transformation?</h3>
It should be noted that when we rotate a point through 90° counterclockwise, the mapping will be: (x, y) to (-y, x).
In this situation, it van be deduced that the x and y coordinates swapped positions. This illustrates a 90° counterclockwise rotation about the origin..
In this situation, since the rotation is a rigid motion, the two shapes are congruent.
