Answer:
The value of S(50) is 22 in means the amount of sodium iodine in the mixture is 22 when 50 milliliters of the 20% solution used.
Step-by-step explanation:
It is given that a chemist working on a flu vaccine needs to mix a 20% sodium-iodine with a 60% sodium-iodine to obtain a 70-milliliter mixture.
Let x be the number of milliliters of the 20% sodium-iodine.
Number of milliliters of the 60% sodium-iodine = 70-x
The amount of sodium iodine in the mixture is 20% of x and 60% of (70-x).
Therefore,the required function is .
Substitute x=50 in the above equation.
The value of S(50) is 22 in means the amount of sodium iodine in the mixture is 22 when 50 milliliters of the 20% solution used.
Let the shortest side = X and the longer = 4X
perimeter = (length + width) ×2
30 = (4X + X)×2
30 = 8X + 2X
30 = 10X divide 10 to both sides
3 = X
the longer side = 4X = 4 × 3 = 12 cm
the shortest side = X = 3 cm
area = length × width
area = 3×12 = 36 cm^2
do you understand ?
