<span>Ending Amt = Bgng Amt * e ^-0.03t
In this equation, the "-0.03" is the decay factor or "k"
We can now solve for half-life by this equation:
</span>t = <span>(<span>ln [y(t) ÷ a]<span>)<span> ÷ -k (we can say beginning amount = 200 and ending amount = 100
</span></span></span></span>t = <span>(<span>ln [200 ÷ 100]<span>)<span> ÷ -k
</span></span></span></span>t = <span>(<span>ln [2]<span>)<span> ÷ -k
</span></span></span></span>t = 0.69314718056<span> ÷ --.03

. The closest number to this is 0.5 which is the same as 1/2
Answer:
5r + (5 x 6) = 84
looking for rice per pound.
Step-by-step explanation:
5r + (5 x 6) = 84
This shows an equation where we need to make r the subject to establish how many pounds a bag of rice weighs.
5r + (5 x 6) = 84
5r + (30) = 84
5r = 84-30
5r = 54/5
r = 10 4/5
r = 10.8 pounds
