Answer:
see below
Step-by-step explanation:
A percentage change is computed as follows:
percent change = ((new value) -(original value))/(original value) × 100%
For your first one, this looks like ...
percent change = ($25 -$75)/$75 × 100% = (-50/75) × 100% = -0.667×100%
percent change = -66.7%

When there are a lot of similar calculations to do, I like to use a spreadsheet. See below for the other percentage changes (rightmost column).
Two negatives is a positive so the equation is Z+3/4=13/2
-3/4
Z=26/4-3/4
Z=23/4
Answer:
sometimes
Step-by-step explanation:
We can consider the example of a cuboid.
It is a rectangular solid whose all faces are made of rectangles.

so we can get some solids whose faces are other than squares as well and some whose faces are squares.
Hence, we could say that:
The faces of a rectangular solid are sometimes square.
