Answer:
approximately 27 grams
Work Shown:
Half life formula
y = A*(0.5)^(x/H)
where,
A = starting amount = 30 grams
H = half life period = 90 years
x = number of years that pass by = 12
y = amount left over after x years
Let's plug the values for x, A and H into the formula to find y
y = A*(0.5)^(x/H)
y = 30*(0.5)^(12/90)
y = 27.3516746567466
y = 27 .... rounding to the nearest whole number

If you would like to solve the equation a/b = c for b, you can do this using the following steps:
<span>a/b = c /*b
</span>a = c * b /c
b = a/c
The correct result would be <span>b = a/c.</span>
4.672 x 10^10, I got this simply by multiplying the two numbers by each other.
