Answer:

Option A

Step-by-step explanation:

The complete question is shown in the attachment.

The sum of angles in a triangle is 180 degrees.

This implies that:

$m\angle A+85+53=180$

m<A+138=180

m<A=180-138=42

Now we use the sine rule to find AC=b

$\frac{b}{\sin 85}=\frac{85}{\sin 42}$

This implies that:

$b=\frac{85}{\sin 42}*\sin 85$

$b=126.5$

Two important ingredients for baking bread are yeast and flour. To make a loaf of bread of at most 30 servings, maintain a yeast

IceJOKER [234]

Answer:

If 0.25 oz of yeast is used, then 50oz of flour is needed.

It would require 0.5 oz of yeast for 90 oz the flour.

Step-by-step explanation:

We know that the proportion of yeast (y) and flour (f) is 1: 200 when a maximum of 30 servings of bread is made. This is:

$\frac{y}{f} = \frac{1}{200}$

So if we use 0.25 oz of yeast:

$y = 0.25\\\\y = (f)\frac{1}{200}\\\\0.25 = (f)\frac{1}{200}\\\\0.25 * 200 = f\\\\f = 50\ oz$

if 0.25 oz of yeast is used, then 50oz of flour is needed.

If you make 60 servings of bread with 90 oz. Of flour, then you should keep the following ratio:

$\frac{y}{f} =\frac{1}{180}$

So, if we use f = 90 0z of flour:

$f = 90\ oz\\\\f = 180y\\\\90 = 180y\\\\y = \frac{90}{180}\\\\y = 0.5\ oz$

It would require 0.5 oz of yeast.
