Answer:
7
Step-by-step explanation:
number of diagonals in a regular polygon = number of sides - 2.
A nonagon is a polygon having 9 sides.
Total number of diagonals in a regular nonagon
= 9 - 2
= 7
Answer:
61 markers
Step-by-step explanation:
41+20=61 markers
The first step to calculate the APR is to calculate the interest rate per $100
Here Interest rate = 11%
Term or time of repayment = 18 months
interest per $100 =
$100 × 11% × 
= $16.50
Now we should calculate the interest part for $3400 for 18 months
× 
= $31.12
So $ 31.17 is the interest part of the repayment amount
Now lets calculate the principal part which would be $ 3400 divided equally for 18 months

Now to find the final payment we add the interest and the principal part
$31.17+$188.89 = $220.06
Hence option D is the right answer
Answer:
C) never
Step-by-step explanation:
It means the system of equations is true for all values of the variables that satisfy one of the equations. The other equation is identical, so any values that satisfy the first equation will also satisfy the second equation.
There will be an infinite number of solutions. There will never be no solution.

<u>Example</u>:
x + y = 4
-x -y +4 = 0
Adding the two equations gives ...
(x +y) +(-x -y +4) = (4) + (0)
4 = 4
The solutions to this system are all values of x and y such that x+y=4. There are an infinite number of such solutions.
