Answer:
Reflective symmetry over the line y=-x
Step-by-step explanation:
This trapezoid is symmetrical around an axis defined by the line y=-x.
It is not, symmetric with an image of itself rotated by 90 degrees. Neither is it symmetric to an image obtained by reflection around -7x+1. These two statements can be easily verified by transforming one of its corner points and realizing they do not belong to the set of corners of the original trapezoid.

Because I said so
Answer:
100 students
Step-by-step explanation:
1. Create a proportion
![\frac{60}{500} =\frac{12}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B60%7D%7B500%7D%20%3D%5Cfrac%7B12%7D%7Bx%7D)
2. Cross-multiply
500×12 = 60x
3. Simplify
6000 = 60x
4. Divide
100 = x
The volume of the shaded region is 1650 cubic feet.
