A bag contains 9 marbles: 3 are green, 2 are red, and 4 are blue. Bob chooses a marble at random, and without putting it back, c

kvasek [131]

Answer: 1/18

Step-by-step explanation:

9 total marbles

2 red

so the first time he picks it would be a 2/9 chance of the marble being red

the second time there would be 8 total marbles and 2 red, so it would be a 2/8 or 1/4 chance.

the probability is found by doing 2/9*1/4 which equals 2/36 or 1/18.

"Rebecca walks 100 feet in a straight line. She then turns 20 degrees to her left and walks another 100 feet, and then turns 20

iragen [17]

Answer:

1,800 ft

Step-by-step explanation:

Rebecca will walk in the pattern of a regular polygon with 'n' sides and internal angles of 160 degrees (180 at a straight line - 20 degrees from each turn).

The equation that describes the internal angle of a regular polygon is:

$A = \frac{(n-2)*180}{n}$

For A = 160 degrees:

$160n=(n-2)*180\\(180-160)n=360\\n=18\ sides$

If each side is 100 ft long, the total distance that Rebecca has walked is:

$d = 18*100\\d=1,800\ ft$

She walked 1,800 ft.
