Answer:
x = 4.56
Step-by-step explanation:
57 + x + 25x + x = 180
27x + 57 = 180
27x = 123
x = 4.56
300(at least or < + =)12n+175
and No because he would have only climbed 295 steps.
6.665 grams of the 13 grams remain after 8 hours.
<h3>How much of a 13 gram sample of iron-52 would remain after 8 hours?</h3>
The decay equation for the 13 grams of iron-52 is:

Where N is the amount of iron-52, and t is the time in years.
Where we used the fact that the half-life is exactly 8.3 hours.
Now, the amount that is left is given by N(8h), so we just need to replace the variable t by by 8 hours, so we get:

So 6.665 grams of the 13 grams remain after 8 hours.
