Answer: The value of cos(0) is 1. This is because when the angle is 0 degrees, the adjacent side of the right triangle is equal to the hypotenuse, and the cosine of 0 is the ratio of the adjacent side to the hypotenuse. Therefore, cos(0) = 1.

 
Explanation: First, we need to understand some basic concepts about trigonometry. Trigonometry is the branch of mathematics that deals with the relationships between the sides and angles of triangles. In particular, the trigonometric functions sine, cosine, and tangent are used to describe these relationships.
 
The cosine function is defined as the ratio of the adjacent side to the hypotenuse of a right triangle. In other words, if we have a right triangle with one angle measuring θ, and the adjacent side to that angle is a, and the hypotenuse is h, then cos(θ) = a/h.
 
Now, let's consider the special case where θ = 0. In this case, the adjacent side to the angle is 0 (since there is no angle to the right of the hypotenuse), and the hypotenuse is simply the length of the hypotenuse. Therefore, cos(0) = 0/h = 0.
 
So, in conclusion, the value of cos(0) is 0. This makes sense, since when θ = 0, the adjacent side of the triangle is 0, meaning there is no horizontal displacement from the origin, which corresponds to cos(0) = 0. This is also reflected on the unit circle, where the x-coordinate of the point where the angle intersects the circle is 1, which corresponds to cos(0) = 1.

## Conversions between Quarts and Gallons

It is possible to convert between any quantity of quarts of gallons using the ratio of gallons to quarts, which is 1: 4

<Snippet ribbon="Example">
<Question tag="Example 1. "> How many Quarts in half a Gallon?</Question>
<Answer tag="Answer:">
Using simple ratios we can find:

$$
1 \text{ Gallon} : 4 \text{ Quarts}
$$

$$
\frac{1}{2} \text{ Gallon} : \frac{4}{2} \text{Quarts}
$$

$$
\frac{1}{2} \text{ Gallon} : 2 \text{ Quarts}
$$

So, half a gallon is equivalent to 2 quarts.
</Answer>
</Snippet>

## Formula for Quarts and Gallons

The formula that can be used for the conversion is:

$$
\text {Volume in Quarts} = \text {Volume in Gallons} \times 4
$$

To find the number of gallons given the volume in quarts, rearrange the formula with “volume in gallons” as the subject,

$$
\text {Volume in Gallons} = \frac {\text {Volume in Quarts}}{4}
$$

<Snippet ribbon="Question">
<Question tag="Question 1. ">Convert 12 Quarts to Gallons.</Question>
<Answer tag="Solution:">
Step 1. Obtain the relevant conversion formula

To determine the volume in gallons, we can use the formula:

$$
\text {Volume in Gallons} = \frac {\text {Volume in Quarts}}{4}
$$

Step 2. Substitute the known quantity in the formula

Substitute 12, for the volume in Quarts in the formula

$$
\text{Volume in Gallons} = \frac{12}{4}
$$

$$
\text{Volume in Gallons} = 3
$$

So, 12 Quarts is equal to 3 gallons.

<Question tag="Question 2. ">How many cups are in a quart?</Question>
<Answer tag="Solution:">

$$
1 \text{ Pint} = 2 \text{ Cups}
$$

$$
2 \text{ Pints} = 2 \times 2 \text{ Cups}

$$
2 \text{ Pints} = 4 \text{ Cups}
$$

$$
\text{The volume of 2 pints is equivalent to 1 quart.}
$$

$$
\text{Therefore,}
$$

$$
1\text{ Quart} = 4 \text{ Cups}
$$

![A visual demonstration of the conversion between cups and quarts step by step](/questions/gallons-to-quarts/pints-cups-quarts.png)

Hence, there are 4 cups in a quart and the ratio between quarts to cups is 1:4.

</Answer>
</Snippet>

<Snippet ribbon="Question">
<Question tag="Question 3. ">Convert 4 quarts to cups.</Question>
<Answer tag="Solution:">
Using the ratio 1:4 between quarts and cups we can determine how many cups are equivalent to 4 quarts in volume.
$$
1 \text{ Quart} = 4 \text{ Cups}
$$

$$
4 \text{ Quarts} = 4 \times 4 \text{ Cups}
$$

$$
4 \text{ Pints} = 16 \text{ Cups}
$$

Therefore, 4 quarts is equal to 16 cups by volume.

![35 c to f](/questions/35-celsius-to-fahrenheit/thermometer-35-c-to-f.png)
 
Explanation: The Celsius scale, named after the Swedish astronomer Anders Celsius, is the most widely used temperature scale across the globe. It defines the freezing point of water at 0 degrees and the boiling point at 100 degrees under standard atmospheric pressure.
 
The Fahrenheit scale, devised by German scientist Daniel Gabriel Fahrenheit, is primarily used in the United States and its territories. This scale sets the freezing point of water at 32 degrees and the boiling point at 212 degrees under standard atmospheric pressure.

### The Formula for Conversion

To convert a temperature from Celsius to Fahrenheit, you can use the following formula:
 
F = (C × 9/5) + 32
 
Where:

F = temperature in Fahrenheit

C = temperature in Celsius

### Step-by-Step Conversion of 35 Degrees Celsius to Fahrenheit

Let's apply the conversion formula to our example of 35 degrees Celsius:
<NumberedList>
<li>
Identify the temperature in Celsius: 35°C
</li>
<li>
Multiply the Celsius temperature by 9/5: (35 × 9/5) = 63
</li>
<li>
Add 32 to the result: 63 + 32 = 95
</li>
</NumberedList>
The result is 95 degrees Fahrenheit. Therefore, 35 degrees Celsius is equal to 95 degrees Fahrenheit.

### Conclusion

Converting temperatures between Celsius and Fahrenheit is a useful skill in a variety of situations, from travel to scientific research. By following the simple formula F = (C × 9/5) + 32, you can easily convert any Celsius temperature to its Fahrenheit equivalent.
