The plutonium isotope has half life

Mathematics
1 answer:
ratelena [41]3 years ago

Answer:

Step-by-step explanation:

The different isotopes have different "half-lives" – the time it takes to lose half of its radioactivity. Pu-239 has a half-life of 24,100 years and Pu-241's half-life is 14.4 years. Substances with shorter half-lives decay more quickly than those with longer half-lives, so they emit more energetic radioactivity.

6 is added a number x.then the result is multiplied by 9. the final answer is greater than 99
drek231 [11]

So this inequality is going to be written as 9(x + 6) > 99


Firstly, you want to foil 9(x + 6), which will look like this: 9x + 54 > 99


Next, subtract 54 on both sides of the equation: 9x > 45


Lastly, divide both sides by 9, and your answer will be x > 5
