Answer:
B) 4 tablespoons of salt
Step-by-step explanation:
Here is the correct question: Scott used 1/3 tablespoons of salt to make 1/4 liters of beans. If Scott's recipe is for 1 liter of beans, how much salt will he need to make triple the recipe?
Given is the ratio of salt and beans to make recipe for 1 liter of beans.
Ratio given for 1 liters of beans; .
Now, simplifying the ratio
∴ Ratio for salt and bean in a recipe for 1 liter of beans is .
Next, finding the proportion of salt to make triple the recipe.
Triple the recipe means 3 times of 1 liter of beans, which is 3 liters of beans.
∴ The proportion of salt in 3 liter beans=
Hence, 4 tablespoon of salt is required to make 3 liters of beans or triple the recipe.

Answer:
is standard equation of hyperbola with vertices at (0, ±9) and foci at (0, ±11).
Step-by-step explanation:
We have given the vertices at (0, ±9) and foci at (0, ±11).
Let (0,±a) = (0,±9) and (0,±c) = (0,±11)
The standard equation of parabola is:
From statement, a = 9
c² = a²+b²
(11)² = (9)²+b²
121-81 = b²
40 = b²
Putting the value of a² and b² in standard equation of parabola, we have
which is the answer.
