If the half-life is t, then every t days, the amount of the radioactive isotope will be cut in half.
(1/2)^(number of half-lives) = 3%
number of half-lives = ln(0.03) / ln(0.5)
This gives the number of half-lives as 5.06.
Then 300 days = (5.06)(length of 1 half-life)
length of 1 half-life = 300 / 5.06 = 59.29 days

The question is incomplete :
However, assume Number of cups of flower 10
Number of flour cups for each pie 1/4
Answer:
8
Step-by-step explanation:
Number of cups of flower = 10
Number of flower cups per crust pie = 1/4 cups
Since, the cups of flower was divided equally into to 5 containers;
Number of flower cups per container :
10 / 5 = 2
Each container has 2 cups of flower each.
1 container was used in making crust pie :
The number of crust pies made is:
Cups of flower in container / cups of flower per crust pie
= 2 ÷ 1/4
= 2 * 4 /1
= 8 crust pies
This is a special 60-30-90 triangle, and the angle measure of x is
