Answer:
It would take 27.5 minutes the element to decay to 154 grams.
Step-by-step explanation:
The decay equation:



Integrating both sides


When t=0, N=
= initial amount





Decay equation:

Given that, the half life of of element X is 11 minutes.
For half life,
, t= 11 min.





[
, since ln|1|=0]
N=154 grams,
= 870 grams, t=?



=27.5 minutes
It would take 27.5 minutes the element to decay to 154 grams.
Answer:
alternate interior angles
Step-by-step explanation:
The angles are alternate interior angles
They are between the parallel lines and on opposite sides of the transversal
Answer:
m=10.5
Step-by-step explanation:
For this equation you could do the long or simple way, I will be using the easier way, you can take the 17 and 6.5, subtract the 17 by the 6.5 and you get 10.5.
m=10.5
I hope that this has helped you, have an great day.
Answer:
