Honestly? Just review your notes and try to work out the problems yourself before taking a look at the answer. You can also google specific topics that the test will cover and try the practice problems.

Answer:
8
Step-by-step explanation:
The formula for the number of degrees in the sum of the interior angles of an n-sided polygon is ...
sum of angles = 180°(n -2)
Filling in the given value and solving for n, we get ...
1080 = 180(n -2)
6 = n -2 . . . . . . divide by 180
8 = n . . . . . . . . add 2
The polygon has 8 sides.
Answer:
Rotations
Step-by-step explanation:
The orientation of the figure is how the whole shape appearance. You don't need to name vertice to determine the orientation of the figure. It will not change from translations and dilations, so these two are out of option.
The orientation of vertices, on the other hand, needs you to know the vertice name. It can be expressed as clockwise or counterclockwise. The orientation of vertice will be preserved for translations, rotations, and dilations so it should be one of them. Notice that translation and dilation already out of option so the answer will be rotations.
I believe its a 1/8 chance.
(-3 1/3) / (4/9).....turn -3 1/3 to an improper fraction
(-10/3) / (4/9)...when dividing fractions, flip what u r dividing by, then multiply
-10/3 * 9/4 ...now just multiply
-30/4 or if u need it back as a mixed fraction, it is - 7 1/2
