1/2

Step-by-step explanation:

so if u do the waffalineneh times by arcimate it would equivently be the answer on top

Answer 2

Answer:

$\frac{1}{2}$

Step-by-step explanation:

The half life is the amount of time it takes a substance to decay to half of its original amount.

Since the radioactive substance has a half life of 1000 years, there will be half of it left after 1000 years.

So, the fraction that will be left after 1000 years is $\frac{1}{2}$
