In cross-country, a team's score is the sum of the place numbers of the first five finishers on the team. The captain of a team placed second in a meet. The next four finishers on the team placed in
consecutive order. The team score was 40. In what places did the other
members finish?

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

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

y - 25 = 2 ( x - 10 ) should be the answer
