An old campfire is uncovered during an archaeological dig. Its charcoal is found to contain less than 1/1000 the normal amount of 
. Estimate the minimum age of the charcoal, noting that 
Answer:
57300 years
Step-by-step explanation:
Using the relation of an half-life time in relation to fraction which can be expressed as:
here;
N represents the present atom
represents the initial atom
t represents the time
represents the half - life
Given that:
Its charcoal is found to contain less than 1/1000 the normal amount of .
Then ;
However; we are to estimate the minimum age of the charcoal, noting that
so noting that , then:
If
Then
Therefore, the estimate of the minimum time needed is 10 half-life time.
For , the normal half-life time = 5730 years
As such , the estimate of the minimum age of the charcoal = 5730 years × 10
= 57300 years
Answer:
the answer is 16mph
Step-by-step explanation:
So first add all of the marbles together: 3+2+6+9=20
Because there are 20 marbles together, that would be your denominator.
All of the other numbers would be your numerator. So you would have:
3/20 green marbles
2/20 yellow marbles
6/20 blue marbles
9/20 red marbles
So your answer would be the probability of picking a red marble from the bag is 9/20 or 45%
Answer: 2 × 3 × 5 × 11 = 330.
Step-by-step explanation: Since, the prime factors of 6600 are 2, 3, 5, 11. Therefore, the product of prime factors = 2 × 3 × 5 × 11 = 330.
Answer:
the slope is 2 I am pretty sure
