X + y = 24....multiply by -3
3x + 5y = 100
---------------
-3x - 3y = - 72 (result of multiplying by -3)
3x + 5y = 100
----------------add
2y = 28
y = 28/2
y = 14 <== 5 pointers
x + y = 24
x + 14 = 24
x = 24 - 14
x = 10 <== 3 pointers
Given that the length of the arc of the circle is, 9.5 ft, thus, the radius of the circle would be: 4.5 ft.
<h3>What is the Length of an Arc?</h3>
Length of arc of a circle = ∅/360 × 2πr
Radius = r.
Given:
∅ = 120°
Length of arc = 9.5 ft
Radius (r) = ?
Thus:
9.5 = 120/360 × 2× 3.14 × r
9.5 = 2.09r
r = 9.5/2.09
r = 4.5 ft

Rewrite the full amount needed as an improper fraction:
2 1/4 = 9/4
Now multiply the full amount by the scale:
9/4 x 1/3 = 9/12
9/12 can be reduced to 3/4
The answer is B. 3/4
