Because all 3 sides are given for both triangles you can use the SSS theorem
Answer is:
6162 years
Explanation:
The given equation to use is:
<span>N=Noe^-kt
First, we will need to define the variables of the equation as follows:
No : original amount of C-14 (at t=0)
N : amount of C-14 at certain time (t)
k : a constant equals </span><span>0.0001
t : the time in years
Now, we are given that:
The skeleton contains 54% of it's original amount of C-14. This means that:
N/No = 54% = 0.54
Substitute with this given in the equation given, we will find that the only unknown is the time (t). We can now solve for t as follows:
</span><span>N=Noe^-kt
This can be rewritten as:
N/No = </span>e^-kt
Now,
N/No = e^-kt
0.54 = e^(-0.0001t)
Take ln for both sides:
ln (0.54) = -0.0001t
-0.61618 = -0.0001t
t = 6161.86 years which is approximately 6162 years
Hope this helps :)
Answer:
the required ratio is 1 : 10
Step-by-step explanation:
1 hour = 60 min
so,
=》 6 min : 1 hour
=》 6 min : 60min
=》1 : 10
Taylor needs to roll a 4, 5, or 6 to win. (3rd option).
A dice has six numbers that might come up in any roll. Taylor needs one of the three named above in order to win.
She has three chances to win the game with the sides 4, 5, or 6. This is half the amount of all the six sides of a dice that she rolls (1, 2, 3, 4, 5, 6).
