So first add all of the marbles together: 3+2+6+9=20
Because there are 20 marbles together, that would be your denominator.
All of the other numbers would be your numerator. So you would have:
3/20 green marbles
2/20 yellow marbles
6/20 blue marbles
9/20 red marbles
So your answer would be the probability of picking a red marble from the bag is 9/20 or 45%
Answer:
57.6159 round if needed
Step-by-step explanation:
We know the length of the triangle which is 298. We know the base of the triangle which is 189.
We need to find angle of elevation so we must use tangent function.

Use inverse tan function

Round if needed.
I hope this helps you
3 same angle one same side

When that equation is graphed, it produces a straiught line. The slope
of the line is 5, and the line intersects the y-axis at y=6.
14×2÷7-3+9=10
Worked it out myslef and enjoy doing math.
