A biscuit recipe calls for 2 pounds of all purpose flour and .75 pound of butter, what would be the baker’s percentage for butte
Goryan [66]

Answer: 37.5%


Explanation:


Percentage is defined as parts of an amount  in 100 parts of a basis. This must be stated mathamatically for better understanding and for calculations. It is the ratio:

             % = (parts / base) × 100.


In this case you need to express the amount of butter as a part in 100 parts of all purpose flour, which, using the above definition, is:


        % butter = (0.75 pounds of butter / 2 pound of flour) × 100

         % butter = 0.75 × 100 / 2 = 75 / 2 = 37.5


The answer is expressed as 37.5%.

In a right triangle the side c opposite the right angle is called the hypotenuse, and the other two sides a and b are
RSB [31]

Answer:

The hypotenuse of the triangle measures 13 inches.

Step-by-step explanation:

Since the Pythagorean theorem states that in any right triangle the lengths of the three sides are related by the equation A ^ 2 + B ^ 2 = C ^ 2, to determine the length of the hypotenuse in a right thangle with legs 5 inches and 12 inches the following calculation should be performed:

5 ^ 2 + 12 ^ 2 = X ^ 2

25 + 144 = X ^ 2

√169 = X

13 = X

Therefore, the hypotenuse of the triangle measures 13 inches.
