Answer:
A rectangle has rotational symmetry of order 2.
Step-by-step explanation:
The rotational symmetry involves rotation.
The rotational symmetry of order is the number of times a shape is mapped onto itself during a 360° rotation.
A rectangle has rotational symmetry of order 2.
When a rectangle is rotated on 180° or 360° it is mapped onto itself.
The answer would be option A "Statement: 60 = 3x + 15; Reason: substitution." Remember that substitution means replacing something with something else. In this case you would be replacing variables separating the term and the variable in two different equations to get your answer.
Therefore your answer is indeed option A.
Hope this helps.

Answer:
$311.20
Step-by-step explanation:
Here we are required to use the Compound interest formula for finding the Amount at the end of 9th year
The formula is given as
Where ,
A is the final amount
P is the initial amount = $200
r is the rate of interest = 5% annual = 0.05
n is the frequency of compounding in a year ( Here it is compounding monthly) = 12
t is the time period = 9
Now we substitute all these values in the formula and solve for A
Hence the amount after 9 years will be $311.20
