Answer: 12

Step-by-step explanation:

For this counting question, we need to figure out the possible choices for each selection.

For main protein, there are four options, so we can make four slots

_ _ _ _

For beans, there's three options, so we can make three slots
_ _ _

Doing some casework, we know that 4*3 = 12, which is the answer.

Once upon a time, there was a former whose family raised pigs and chickens. One morning, the farmer's wife looked into the barny
Fed [463]

Using a system of equations, it is found that:

  • There are 8 chickens in the yard.
  • There are 16 pigs in the yard.

-----------------------------------------

This question is solved using a system of equations. I am going to say that:

  • x is the number of chickens.
  • y is the number of pigs.

-----------------------------------------

  • A chicken has 1 head, as do a pig.
  • There are 24 heads.

Thus:

x + y = 24 \rightarrow y = 24 - x

-----------------------------------------

  • A chicken has 2 feet.
  • A pig has 4 feet.
  • In total, there are 80 feet.

Thus:

2x + 4y = 80

-----------------------------------------

Number of chicken:

Since y = 24 - x

2x + 4y = 80

2x + 4(24 - x) = 80

2x + 96 - 4x = 80

2x = 16

x = \frac{16}{2}

x = 8

There are 8 chickens in the yard.

-----------------------------------------

Number of pigs:

y = 24 - x = 24 - 8 = 16

There are 16 pigs in the yard.

Find the exact values of sin A and cos A. Write fractions in lowest terms. (5 points) A right triangle ABC is shown. Leg AC has
swat32

sin\ A = \frac{4}{5}\\\\cos\ A = \frac{3}{5}

<em><u>Solution:</u></em>

Given a right triangle ABC

The figure is attached below

From given,

AC = Base = 33

BC = Perpendicular = 44

AB = hyptotenuse = 55

We know that,

Sin\ A = \frac{perpendicular}{hypotenuse}\\\\Sin\ A = \frac{44}{55}\\\\Sin\ A = \frac{4}{5}

Also,

cos\ A = \frac{base}{hypotenuse}\\\\cos\ A = \frac{33}{55}\\\\cos\ A = \frac{3}{5}

Thus the values are found
