Answer:
Ending Amount = Beginning Amount / 2 ^ n
where 'n' = number of half-lives n = 65 / 29 = 2.2413793103
Ending Amount = 25 g / 2^2.2413793103
Ending Amount = 25 / 4.7284892286
Ending Amount = 5.2871009727 g = 5.29 g (rounded)
Step-by-step explanation:
Divide both sides of -105=-5g by -5. You'll get g = -105 / (-5), or g = 21.
Hey there!
Here is your answer:
The proper answer to this question is "44" .
Reason:
Think of it like this:
| | <---- This represents a car wash
When you add a positive or negative number in between the lines it represents a car going through the car wash.
So if...
|-44| (goes through the car wash)=44
|44| (goes through the care wash)=44
Therefore it would equal 44.
