Answer:
It is (6,4)
Step-by-step explanation:
If x is the number of sides of the regular polygon, then the sum of the interior angles is (x - 2) * 180 = 56 * 90. Solving for x gives 30 for the number of sides of the regular polygon.
To get the central angles measure, divide 360 by 30 to get 12 degrees for the measure of one of the 30 central angles.
Answer: 12 degrees
Answer:
Nico invest at 7% and at 3%
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
<em>At 7%</em>
substitute in the formula above
<em>At 3%</em>
substitute in the formula above
The total interest is equal to
I=I1+I2
I=$174
substitute
therefore
Nico invest at 7% and at 3%
The area is 33.3in squared
Answer: $53
Step-by-step explanation:
17+ .09m = 9 + .11m
8 = .02m
m = 8/.02= 400 minutes for the two plans to cost the same
9+.11(400) = 9+ 44 = $53 when they cost the same
17+.09(400) = 17 +36 = $53
