If 5 bags of apples weigh 12 1/7 pounds, how many pounds would you expect 1 bag of apples to weigh?

  2 and 3/7 pounds

Step-by-step explanation:

Convert the mixed number to an improper fraction

12 1/7 becomes 85/7

This represents 5 bags, so divide it by 5 to see what one bag should weigh...

(85/7)/5 becomes (85/7)/(5/1)

which becomes

(85/7)*(1/5)      (division is the same as multiplying by the reciprocal)

   85/35  

     17/7      (reduce the fraction by factoring out a 5 from top and bottom)

       2 and 3/7 pounds

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
