If the number of hours left in the day is half the number of hours already passed, what time is it?
The time is 4:00 PM.
8 hours left in the day and 16 hours already passed.
To solve,
Hours left is a, so hours already passed = 2a.
We know a + 2a = 24
3a = 24
a = 8
2a = 16
So, time is 4 PM.

How many half-lives have passed?
To determine how many half-lives have passed, you would need to divide the total time passed by the half-life of the substance. The result would give you the number of half-lives that have occurred.

How much of an 848 g sample of potassium-42 will there be left after 62.0 hours?
To determine the amount of potassium-42 left after 62.0 hours, we need to use the half-life of potassium-42 which is 12.4 hours. Calculate the number of half-lives that have passed (62.0 hours / 12.4 hours) = 5 half-lives. Each half-life halves the amount, so 1/2^5 = 1/32. Therefore, there will be 848 g * (1/32) = 26.5 g of potassium-42 left.
