Mr. Fulton bought 12 1/2 pounds of ground beef for the cookout. He plans on using 1/4 pound of ground beef for each hamburger. H
vekshin1

Answer:

Mr. Fulton can make 50 hamburgers.

Step-by-step explanation:

Given:

Total amount of ground beef = 12\frac{1}{2} \ pounds

12\frac{1}{2} can be Rewritten as \frac{25}{2}

Total amount of ground beef = \frac{25}{2}\ pounds

Amount of beef used for each hamburger = \frac{1}{4}\ pound

We need to find the number of hamburgers could he make.

Solution:

Now we can say that;

number of hamburgers can be calculated by Total amount of ground beef divided by Amount of beef used for each hamburger.

framing in equation form we get;

number of hamburgers = \frac{\frac{25}{2}}{\frac{1}{4}} = \frac{25}{2}\times \frac{4}{1} = 50

Hence Mr. Fulton can make 50 hamburgers.

Yuri thinks that 3/4 is a root of the following function.
sineoko [7]

Given:

The polynomial function is

q(x)=6x^3+19x^2-15x-28

Yuri thinks that \dfrac{3}{4} is a root of the given function.

To find:

Why \dfrac{3}{4} cannot be a root?

Solution:

We have,

q(x)=6x^3+19x^2-15x-28

If \dfrac{3}{4} is a root, then the value of the function at \dfrac{3}{4} is 0.

Putting x=\dfrac{3}{4} in the given function, we get

q(\dfrac{3}{4})=6(\dfrac{3}{4})^3+19(\dfrac{3}{4})^2-15(\dfrac{3}{4})-28

q(\dfrac{3}{4})=6(\dfrac{27}{64})+19(\dfrac{9}{16})-\dfrac{45}{4}-28

q(\dfrac{3}{4})=3(\dfrac{27}{32})+\dfrac{171}{16}-\dfrac{45}{4}-28

q(\dfrac{3}{4})=\dfrac{81}{32}+\dfrac{171}{16}-\dfrac{45}{4}-28

Taking LCM, we get

q(\dfrac{3}{4})=\dfrac{81+342-360-896}{32}

q(\dfrac{3}{4})=\dfrac{-833}{32}\neq 0

Since the value of the function at \dfrac{3}{4} is not equal to 0, therefore, \dfrac{3}{4} is not a root of the given function.
