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%
Step-by-step explanation:
here's the solution :-
1.) =》f = 90°
( because angle made by diameter on circumference of the circle measures 90° )
2.) =》here,
g + f + 56° = 180°
( because the sum of all interior angles of the triangle measures 180° )
=》g + 90° + 56° = 180°
=》g + 146° = 180°
=》g = 180° - 146°
=》g = 34°
3.) h = 56°
( since, they form alternate interior pair which are equal )
Answer: 
Step-by-step explanation:
The complete exercise is: "The circumference of a circle is 47.1 and the diameter of the circle is 15. Which best represents the value of π? "
In order to solve this exercise, it is important to remember that the circle can be calculated with the following formulas:
1. 
Where "C" is the circumference of the circle and "D" is the diameter of the circle.
2. 
Where "C" is the circumference of the circle and "r" is the radius of the circle (Remeber that the diameter is twice the radius).
In this case, the exercise gives you the circumference of the circle and its diameter. These are:

Then, knowing those values, you can substitute them s into the first equation
, as following:

The final step is to solve for
:

(37 1/2) /100
37.5/100
anything divided by 100 means you move the decimal point to the left two spaces
answer=0.375
