Answer:
Number of sides are 12.
Step-by-step explanation:
Given that smallest angle of rotational symmetry for a regular polygon is 30°.
we have to find the number of sides does the regular polygon have.
If we can rotate a figure around a center point by fewer than 360° and the figure appears unchanged, then the figure has the rotation symmetry.
Now as at the centre the angle is 360 and all the angles at the centre formed equal i.e
Hence, 12 number of sides the polygon have.
The steps are:
In the first step you subtracted 5 from both sides, in the second step you divided both sides by 3.
Answer:
a) $225.29
Step-by-step explanation:
We are given
Adan has decided to purchase an $9000 car
he plans on putting 20% down toward the purchase
so,
loan amount = 80% of 9000
financing the rest at 7.9% interest rate for 3 years
so,
r=7.9%=0.079
now, we can find i
i=0.00658
t=3
we can use formula
now, we can plug values
now, we can simplify it
So,
His monthly payment is $225.2765
The answer is 5/7 . 30/2=15 42/2=21 15/3=5 21/3=7
