THE QUESTION IS INVALID. THE HALF-LIFE OF FLUORINE-20 is 11.07 SECONDS.
There will be about 0.92 of of an isotope with a half-life of 114 seconds remaining after 14 seconds.
The equation for half-life decay is AT = A0 2(-T/H) where T is time and H is half-life.
2(-14/114) is equal to about 0.92.
In the case of fluorine-20, 2(-14/11.07) is about 0.42.

To determine the age of the artifact, you can use the formula for exponential decay of radioactive elements: (N = N_0 \times (1/2)^{t/T}), where N is the final amount (3.1% of the original), N0 is the initial amount (100%), t is the time passed, and T is the half-life (5730 years). By substituting the values, you can solve for t, which will give you the age of the artifact.
Carbon dating measures the amount of carbon halflives that an object's carbon-14 has seen. A halflife is the amount of time it takes for half of the C-14 present to decay into a different element (N-14). A carbon halflife is 5730 years so you wouldn't be able to tell with such a small amount of time.
The halflife of 235U is 704 million years. 1420 million years is approximately two halflives, so about 24.7% would be remaining.
After 4 days, only 1/16 of the original amount of gold (198/16 = 12.375) will remain.

To determine the half-life of the substance, you can use the fact that after one half-life, the substance will be reduced to half of its original amount. In this case, after 40 days, the substance is reduced to one sixteenth of its original amount, which represents 4 half-lives (since 1/2^4 = 1/16). Thus, each half-life of this substance is 10 days.
the amount of an original investment is called
The original amount was 1214.12
The amount of minutes that are there in 28,000 seconds is 466.666667 minutes. The amount of hours that are in twenty-eight thousand seconds is 7 7/9 hours.
new amount minus original amount over original amount
percent increase=(new amount-original amount) _____________________ original amount
Greater than 100 if the original amount is positive. Less than 100 if the original amount s negative.

You multiply the amount of minutes by the amount of seconds in a minute. 27*60 The answer is 1620
