in a box of stones, the ratio of red marbles to total marbles 2:5. The ratio of green stone to total stones is 3:10. If the stones that are neither red nor green is blue, how many blue stones are the box if there are 40marbles in the box?

12 blue marbles

Step-by-step explanation:

multiply 2:5 by 8 to get 16:40

multiply 3:10 by 4 to get 12:40

add 16 to 12 to get 28

Subtract 28 from 40 to get 12

Ultimately, you have 12 blue marbles

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
