Answer:

9 days

Step-by-step explanation:

He sets his watch 12 seconds behind

For every day that passes it falls back another 1 second

So once it is 21 seconds behind all you have to do is subtraction to find the amount of days past

21 - 12 = 9

Since its 12 seconds behind already itll take 9 days to be behind 9 more seconds.

Answer: 27/36

Step-by-step explanation: It says there are 36 bikes (18 pairs), meaning that there are 2 bikes per pair because 18 multiplied by 2 is 36.

1 pair (2 bikes) are yellow.

3 pairs (6 bikes) are red.

For purple, add yellow and red together: 2 + 6 = 8. Subtract the total number of bikes from this: 36 - 8 = 28 purple bikes.

If you take out 1 purple bike, this leaves you with 27. The probability of choosing a purple bike out of the total (36), is 27/36.

Please let me know if this is correct or wrong.
