Answer:
8923 years
Step-by-step explanation:
Half life of C-14 = 5730yrs
decay rate= 34%
Halt life (t^1/2) = (ln2) / k
5730 = (ln2) /k
k = (ln2) / 5730
k = 1.209 * 10^-4
For first order reaction in radioactivity,
ln(initial amount) = -kt
ln(34/100) = -(1.209*10^-4)t
-1.0788 = -(1.209*10^-4)t
t = -1.7088/ -1.209*10^-4
t = 8923 years
Answer:
The product is 1.05
another pair of factors with the same product are 6/10 x 14/8
Answer:
Divide 12 by 4 first to figure out how many gallons are in each 1/4 of the tank.
12/4=3
So if I added another 1/4 to the capacity:
It could hold 15 gallons.
All you have to do to find how many half bottles can be filled is to times 15 by two since we are filling half gallon bottles.
15x2=30
30 bottles.
1: slope = 2/1 or 2
2: slope = 5/-5
3: slope = 3/2
4: slope = 7/-4
5: slope = 3/5
6: slope = 2/-8
7: slope = 6/2 or 3
8: slope = 2/-4
9: slope = 1/6
