That is exactly 8 half lives.
After 8 half - lives only (1 / 2^8) or (1 / 256) of the original 30 grams will remain.
(1 / 256) =
<span>
<span>
<span>
0.003906250
</span>
</span>
</span>
So, 30 * <span>
<span>
0.003906250 = </span></span>
<span>
<span>
<span>
0.1171875 grams will remain.

The answer would be 22.33 hope this helped
5! Is the same as 5x4x3x2x1 and 4! Is the same as 4x3x2x1 because 4! Is in the denominator it cancels the 4x3x2x1 in the numerator and you are left with 5x(3!) witch is the same a 5x3x2x1. The answer=30
With the concept of first in, first out method, then we
can use the formula below to solve for the number of equivalent units of
production for that period.
number of equivalent units of production
= Total number of units completed during that period (A) –
Number of units completed in process at the beginning of the period (B) +
Number of units completed at the end of the period (C)
= A – B + C
We know that,
A = 9000 units
So we solve for B and C.
B is 60% of the 500 units, therefore:
B = 0.60 * 500 = 300
C is 30% of the 600 units, therefore:
C = 0.30 * 600 = 180
Substituting the values into the equation:
number of equivalent units of production = 9000 – 300 + 180
number of equivalent units of production = 8880 units
Answer:
A. 8880
