Answer:
The inequality represents the scenario is .
Step-by-step explanation:
Given:
Number of minutes used to make cookie written on box = 30 minutes.
Number of minutes used to make cookies =
We need to write inequality represents the scenario
Solution:
We can say that;
Number of minutes used to make cookies should be less than or equal to Number of minutes used to make cookie written on box.
framing in equation form we get;
Hence The inequality represents the scenario is .
Everyday about 200 people visited the store Because you would divide 2744 by 14 and get 196 and round that to 200
Answer:
The age of the spear head to the nearest year is 1845 years
Step-by-step explanation:
We know that
half life time of C-14 is 5730 years
so, h=5730
we can use formula
now, we can plug value
an archaeologist in turkey discovers a spear head that contains 80% of its original amount of C-14
so,
we can plug it
now, we can solve for t
So,
The age of the spear head to the nearest year is 1845 years
