Answer:
The length of the blue ribbon is approximately 8.333 inches
Step-by-step explanation:
The given information are as follows;
The given length of the red ribbon = 2 1/12 inches
The length of the blue ribbon is given as 4 × The length of the red ribbon
Therefore;
The length of the blue ribbon = 4 × 2 1/12 inches = 25/3 inches = 8 1/3 inches
The length of the blue ribbon = 8 1/3 inches ≈ 8.333 inches.
We have 89 ounces of 47% iodine.
We will add "x" ounces of 14% iodine to get a 29% iodine solution.
89 * .47 + .14x = .29 * (89 + x)
41.83 + .14x = 25.81 + .29x
16.02 = .15x
x = 106.80
So, we must add 106.80 ounces of 14% iodine to get a 29% iodine solution.
(for a total of 195.80 ounces)
