when Mrs. Stewart makes pie dough, she uses 2/3 cup of shortening for every 2 1/2 cups of flour which proportion could be used t
Scrat [10]

Answer:

The amount of floor Mrs.Stewart needs for 5 cups of shortening =\frac{75}{4} =18\tfrac{3}{4} cups.

Step-by-step explanation:

Mrs.Stewart pie dough needs \frac{2}{3} cups of shortening for 2\tfrac{1}{2}=\frac{5}{2} cups of flour.

Now we assume that the shortening needed for x cups of flour is y cups.

Accordingly we can arrange the ratios.

\frac{cups\ of flour\ (x)}{cups\ of\ shortening\ (y)} =\frac{x}{y} =\frac{5/2}{2/3}

Plugging the value of y=5 as it is number of cups of shortening Mrs.Stewart have used.

And multiplying both sides with 5,we have

Number of cups of flour (x) =\frac{x}{y} =\frac{5/2}{2/3}

So (x) =\frac{5\times 3\times 5}{2\times 2} =\frac{75}{4} = 18\tfrac{3}{4}

The amount of floor Mrs.Stewart needed for 5 cups of shortening = 18\tfrac{3}{4}\ cups.

Hey can someone please help explain and answer this 1 question. There's a picture. Thank you!
Vilka [71]
The graph shown in the picture is a hyperbola. It can be shown that the center lies on the line of symmetry. In this case, it can be seen that center of the hyperbola is at (3,-5). A hyperbola has an equation of x^2/a - y^2/b =1. a and b are the units between the two curves. a and b are both equal to 4. SInce the center is (3,-5), the equation of the parabola is  (<span>x-3)^2/4 - (y+5)^2/4 =1.</span>
