Answer:
A = 0.75 gram or 1 gram
Step-by-step explanation:
The half-life of carbon 14 is years. How much would be left of an original -gram sample after 2,292 years? (To the nearest whole number).
We can use the following formula for half-life of to find out how much is left from the original sample after 2,292 years:
where:
<em>A</em> is the amount left of an original gram sample after <em>t</em> years, and
is the amount present at time <em>t</em> = 0.
The half-life of is the time <em>t</em> at which the amount present is one-half the amount at time <em>t </em>= 0.
If 1 gram of is present in a sample,
Solve for A when t = 2,292:
Substituting = 1 gram into the decay equation, and we have:
A = 0.75 g or 1 g
If you divide 5 over 3 you get the decimal 1.6, not 15.
the correct answer would be 45.
how do i get that? read below.
________________________________
to solve:
1.multiply each side by 3, to get the 3 on the left side to cancel out. so you get x = 15 times 3.
2. 15 * 3 = 45
the correct answer would be 45.
