The half-life of uranium-235 is 700,000,000 years. The half-life of uranium-238 is 4.463 × 1011 years longer. What is the half-life of uranium-238? The answer should be in decimal form. (1 point)

Question

11,463,000,000
4.4637 x 1011
516,300,000,000
447,000,000,000

Answer 1

To find the half-life of uranium-238, we need to add the half-life of uranium-235 to the additional time given for uranium-238.

The half-life of uranium-235 is 700,000,000 years, and uranium-238 has a half-life that is 4.463 × 10^11 years longer.

First, let's convert 4.463 × 10^11 into decimal form: 4.463 × 10^11 = 446,300,000,000 years

Now, we add the half-life of uranium-235 to this value: 700,000,000 + 446,300,000,000 = 447,000,000,000 years

So, the half-life of uranium-238 is 447,000,000,000 years.

The correct answer is: 447,000,000,000
