Answer: A. preserves length, angle measures and distance between points
Rigid motions or isometries are any of the three transformations below
- translation (aka shifting)
- rotation
- reflection
Any of those three transformations will keep the figure the same size and shape. That means distances between any two points are kept the same, and angle measures are kept the same as well. Everything is kept the same. The only difference is that the figure is in a different location, is rotated somehow, or it is reflected some way. You can use a series of transformations to undo everything to get the original figure back.
If you wanted to change the size of the figure, then you would apply dilation, which isn't an isometry.
Answer:
Step-by-step explanation:
How many questions is 90% of 20? That's the question we need to answer. Algebraically, the equation looks like this:
x = .90(20) so
x = 18
If she only answered 16 correctly, she did not get the A. She needed to answer 18 correctly, because 18 is 90% of 20.

Answer:
8864.73
Step-by-step explanation:
A=p(1+r)^t
A future value ?
p the principle 6000
r interest rate 0.05
t time 8 years
A=6000×(1+0.05)^8
A=8864.73
2/6 divided by 4/12
First, make 2/6 have a denominator of 12 to complement the fraction 4/12
2/6=4/12
4/12 divided by 4/12 is 1
So, 1 would be your answer.
Hope I helped!
