Answer:
+38000
Step-by-step explanation:
All circles are similar.
If they were congruent, they would have the same radius's/diameter's.
Circle B = diameter of 6
Circle A = radius of 4
Diameter = 2 * Radius
Circle A = diameter of 4 * 2 = 8
So they have different diameter's, therefore they are not congruent. So they are similar only.
400+8x=800-6x.
Solving for x, you get 14x=400, and x is around 28.57
So it takes around 28.57 minutes for them to have the same amount of water.

1. 25% too because it wont change if they have the same amount of marbles.
2. 5% since there is very little gold marbles.
3. Take out 55 red marbles so it could be fair or just take out red marbles in general. That would be fair.
Hope I helped. Have a great day
