Answer: the movie was 1 hour and 35 minutes and Amar got home at 6:15 P.M.
Step-by-step explanation:
to find out how long the movie was you have to find the distance between the time frames 3:55 and 5:30.
3:55+1 hour= 4:55
4:55+5 minutes= 5:00
5:00+30 minutes= 5:30
Add the times to find how long the movie was.
This is how I found how long the movie was.
To find out when Amar got home you have to do the same thing as well.
5:30+30 minutes= 6:00
6:00+15 minutes= 6:15
Hope this helps!
Answer:
The mammoth died 17.190 years ago.
Step-by-step explanation:
Given information:
- Half-life of C-14 is 5.700 years.
- Living elephant bones commonly contain about 40% C-14.
For every 5700 years, the elephant's bones losses a half-life of C-14. And supposing that the living mammoth bones had the same percentage of C-14.
If the mammoth when living has 40%, then:
- After 5.730 years, the mammoth bones will contain 20%.
- After 11.460 years(2 half-lives), the mammoth bones will contain 10%.
- After 17.190 years(3 half-lives), the mammoth bones will contain 5%.
