Let's solve ~




I hope you understood the procedure, please let me know if you have any doubts
A geologist in South America discovers a bird skeleton that contains 80% of its original amount of C-14
We use formula 
N0= initial amont of C-14 (at time t=0)
N= amount of C-14 at time t
t= time, in years
k= 0.0001
N is 80% of N0 that is 


Divide both sides by N_o

Take ln on both sides

ln(0.8) = -0.0001t ln(e)
ln(0.8) = -0.0001t
Divide both sides by -0.001
t = 2231.435513
The age of the bird skeleton is 2231 years old
Answer:
- 9°C is less than -4°C
Step-by-step explanation:
The reason that why these temperatures are related because when we start counting the numbers from left, it becomes smaller. For ex- 3 is on the left of 5. So, 3 is smaller than 5. That's how when we start counting from the left in negative numbers, the negative numbers gets smaller.
Answer:
30
Step-by-step explanation:
You already have 40 points and every movie is two points. 100-40=60. 60 divided by 2 is 30, so you still need to watch 30 more movies.
