Explanation:
The time it takes for 1g of strontium-90 to decay to 250 mg is; 57.6 years
<h3>What is the half life of an element?</h3>
The formula for half life is;
A(t) = A₀ * (¹/₂)^(t/t_1/2)
Where;
A(t) is amount left after t years
A₀ the initial quantity of the substance that will undergo decay;
t_1/2 is the half-life of the decaying quantity.
We are given;
t_1/2 = 28.8 years
A₀ = 1 g
A(t) = 250 mg = 0.25 g
Thus;
0.25 = 1 * (¹/₂)^(t/28.8)
log 0.25 = (t/28.8) log (1/2)
-0.60206 = (t/28.8) * -0.3010
t = 2 * 28.8
t = 57.6 years

Answer:
Farrah: 5 pieces of (3/4) blue yarn, 1 piece of (1 3/5) red yarn, and 1 piece of (2 1/2) green yard
Alice: 3 pieces of (3/4) blue yarn, 2 pieces of (1 3/5) red yarn, and 1 piece of (2 1/2) green yard
Pia: 9 pieces of (3/4) blue yarn
Explanation: Farrah: (0.75*5)+1 3/5+2.5 = 7.85 ft
Alice: (0.75*3)+(1 3/5*2)+2.5= 7.95 ft
Pia: 0.75*9 = 6.75 ft
A). Food and Drug Administration (FDA)
-The FDA was established around the early 1900s (06') after health problems between production and regulations of factory processed food [and drugs], mostly on the process of meat. (I remember learning this in US History, they blended rats along with human fingers in some of the meat, selling it to people. The book: "The Jungle" also caused this act to come in place)
-I didn't mean to go into history of this lol
The other answers would not make sense as their mission focuses on other regulations.
Hope this helps :)
