The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. starting with 130 grams of a radioactive isotope, how much will be left after 5 half-lives?

use the calculator provided and round your answer to the nearest gram.

= 4 grams

Step-by-step explanation:

The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass.

Therefore, using the formula;

N = O × (1/2)^n ; where N is the new mass, O is the original mass, and n is the number of half lives.

In this case;

N = 130 × (1/2)^5

   = 130 × 1/32

   = 4.0625

   ≈ 4 g

step-by-step explanation:

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
