2 inches
Step-by-step explanation:
36 divided by 6= 6
So 12 divided by 6 is 2
Answer:
3.05 yards
Step-by-step explanation:
Arc length= 2π(r)(Θ/360)
given: 7 yards is diameter, 50 degrees
radius= diameter/2 = 3.5
plug in
2π(3.5)(50/360) = 3.05 yards
This is a fairly easy half-life problem
Each half-life reduces the radioactive material by one half.
So after 72 hours the radioactive material would have undergone 6 half-lives.
2^6 = 64.
So, there will be one sixty-fourth of the material left.
520 / 64 = 8.125 grams will remain.
radioactive decay is an exponential decay function.
