Gary gets 4 marbles, because 12/3 is 4. So for the ratio 3:1 to apply, Jo gets 12 marbles and Gary gets 4.
Answer:
5.00
Step-by-step explanation:
Radius = 15
side = 6.215
a^2 = 15^2 - 6.215^2
a = 13.65
Area = a × p
Area = 13.65 × 99.44
Area = 1357.356
3x +2y= 11 ----1
x -2 = -4y ---- 2
Equation 2 times by 3
3x -6 = -12y
Subracting 2-1
3x-6=-12y
3x-11=-2y
Leaving
5=-10y
y= -1/2
Hence
B. is the solution
