This is a pretty easy half life problaem.
There are formulas for calculating this using "e" but I have a simpler formula which you can find here:
http://www.1728.org/halflife.htm
Ending Amt = Beginning amount / 2^n
where n is the number of half-lives
n = 1
Ending Amt = Beginning amount / 2^1
Ending Amt = 1,000 / 2
Ending Amt = 500 grams
5x>/ 45
at least means it can be 45 and up
So it becomes greater than or equal to
<span>Just find the distance from -3 to 4. That's 7.
It is 7 units to the left of -3. Subtract 7 from -3. That's -10</span>
Answer:
numerator = 3
denominator = 4
