Answer:
60*0.8 raised to the t power where t is time
Step-by-step explanation:
60*0.8³=30.72
60*0.8∧4.25=23.24254578
<span> half life i= 78 hours
amount after 78 hours is 395 kg:
395 = 790e^(k*78)
Dividing by 790 and taking natural log
ln (395/790) = (k*78)
-0.6931 = 78k
-0.00888 = k
lets calculate how much is left after 18 hours:
Amount(18)
= 790e^(-0.00888*18)
Amount = 673.301 kg

It depends on how many sides it has
If it has 2 then 50 percent
If it has 4 then 25 percent
If it has 5 then 20 percent
You divide the amount of sides by 100
x / 100 = percent
Example 2 / 100 = 50.
