Find the angular displacement of 12.2 revolutions. Use π=3.14. Round the answer to the nearest tenth.

1 answer:

3 0

The angular displacement may be solved using the concept that each revolution is equal to 2π rad. Since the problem asked for the angular displacement of 12.2 rev, multiply 2π by 12.2. This operation gives an answer of 122π/5 which is approximately equal to 76.6. Thus, the answer is the third choice.

Answer:

see below

Step-by-step explanation:

10 are blue, 30 are yellow, 20 are red, and 40 are green.

There are 100 marbles in the bag

The color that has the most marbles is green

P( green) = 40/100 = 40%

P( yellow) = 30/100 = 30%

P( red) = 20/100 = 20%

P( blue) = 10/100 = 10%

You will be more likely to pick a green marble
