For the general case, the n-gon, you got
degrees. The 13-gon thus has 1980 degrees in total.
Angle of fire in degrees: 90° + 30° = 120°
Angle of fire in radians: 180° = π
120° * π/180° = 120°π / 180° OR 4π/6 OR 2π/3
Answer:
s = -3
Step-by-step explanation:
1 = 4s + 13
rewrite
4s + 13 = 1
4s = 1 - 13
4s = -12
s = -3
<span>Each ticket costs $10. He bought "x" tickets. Ticket cost = 10*x
Each bag of popcorn costs $5.
He bought "y" bags of popcorn.
Popcorn cost = 5*y
Service fee: $3
Total cost = 10x + 5y + 3 <= $75 is the inequality.
10x + 5y <= 72
If x = 4,
then 40 + 5y <= 72
5y <= 32
y <= 6.4
So y = 6 bags of popcorn.</span>
