6.665 grams of the 13 grams remain after 8 hours.
<h3>How much of a 13 gram sample of iron-52 would remain after 8 hours?</h3>
The decay equation for the 13 grams of iron-52 is:
Where N is the amount of iron-52, and t is the time in years.
Where we used the fact that the half-life is exactly 8.3 hours.
Now, the amount that is left is given by N(8h), so we just need to replace the variable t by by 8 hours, so we get:
So 6.665 grams of the 13 grams remain after 8 hours.

Answer:
-12p-20
Step-by-step explanation:
{-12-6p-(-2)}−12−6p−(−2)
-12-6p+2−12−6p+2
-12p-20
Answer: x=13
explanation:
-2x+6=-20
subtract 6 from both sides
-2x=-26
divide -2 by both sides
two negatives equals a positive
x=13
(750m) - 1050 = b
1800 - 1050 = 750 dollars lost.
So (750m) - 1050 = b will give you the balance.
