the problem is a pattern that multiplies by two and subtracts one each time. 
3x2=6 6-1=5 5x2=10 10-2=9 9x2=18 18-1=17 17x2=34 34-1=33
 
        
                    
             
        
        
        
Answer:
60.39 inches
Step-by-step explanation:
Given that:
A Pac-Man poster which is having three fourth of a circle and there are two sides.
Diameter of circle = 18 inches
Sides of Pac-Man poster = 9 inches
To find:
Perimeter of the Pac-Man poster.
Solution:
Perimeter of a figure is nothing but equal to the periphery i.e. the outer area of the circle/figure.
Perimeter of a circle is given by the formula:
Perimeter = 
 is the radius of the circle.
 is the radius of the circle.
Radius is half of perimeter.

Perimeter of the Pac-Man poster = Perimeter of  circle + 2 sides
 circle + 2 sides
Perimeter of the Pac-Man poster =  + 9+9 = 42.39+28 = <em>60.39 inches</em>
  + 9+9 = 42.39+28 = <em>60.39 inches</em>

Answer:
Step-by-step explanation:
60 sec= 1 min
60min=1hour
24hours=1day
7days=1week
52 weeks =1 year
24x7= 168hours in a week
168hours x 52 =8736 hours in a year
8736x60=524160mins
524160mins=  1 year
the heart beats 103680 in a year
the heart will beat 524160/103680=5.05555555556 in a minute
