The plutonium isotope has half life

Mathematics
1 answer:
ratelena [41]3 years ago
6 0

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.

2) 15.3 + 11.22x > -14.25 - 10.2x - 24

3) 15.3 + 11.22x > -38.25 - 10.2x

4) 11.22x + 10.2x > -38.25 - 15.3

5) 21.42x > -53.55

6) x > -2.5

Alternate forms

The measurement of the width of a garden plot is 44 m. Its actual width is 45.5 m.
romanna [79]
Answer:  -3.3%

By not knowing how i did it, means you will still not know how to do it next time you encounter a similar problem.

Knowing how to solve a problem is just as important or even more important than just knowing the solution.

Marcus spent 2 hour reading,1 hour playing Rocket League,and took a 2 hour nap. What percent of the total time did he read?
Alona [7]

Answer: He read 40% of the total time.

Step-by-step explanation:

As per given,

Total time he spent = 2 +1+2 = 5 hours

Number of hours he spent on reading = 2 hours

The percent of the total time he read = \dfrac{\text{Number of hours read}}{\text{Total time spent}}\times100

=\dfrac{2}{5}\times100\\\\=40\%

i.e. The percent of the total time he read  = 40%

Hence, he read 40% of the total time.
