Use the formula F = 1.8C + 32 to convert 45 degrees Celsius into Fahrenheit.

Use the formula F = 1.8C + 32 to convert 45 degrees Celsius into Fahrenheit.

The Correct Answer and Explanation is:

To convert 45 degrees Celsius to Fahrenheit using the formula F=1.8C+32F = 1.8C + 32F=1.8C+32, we follow these steps:

Step 1: Write the formula

The formula to convert Celsius to Fahrenheit is:F=1.8C+32F = 1.8C + 32F=1.8C+32

Step 2: Substitute the Celsius value

We are given 45°C, so substitute C=45C = 45C=45 into the formula:F=1.8(45)+32F = 1.8(45) + 32F=1.8(45)+32

Step 3: Perform the multiplication

Now multiply 1.81.81.8 by 454545:1.8×45=811.8 \times 45 = 811.8×45=81

Step 4: Add 32

Now add 32 to the result:F=81+32=113F = 81 + 32 = 113F=81+32=113

Final Answer:

So, 45°C is equivalent to 113°F.

Explanation:

The formula F=1.8C+32F = 1.8C + 32F=1.8C+32 is derived from the relationship between the Celsius and Fahrenheit temperature scales. The factor 1.8 (or 9/5) is used to adjust for the different size of the temperature units between the two scales. The addition of 32 accounts for the offset where 0°C equals 32°F. The result gives the temperature in Fahrenheit.

Converting between Celsius and Fahrenheit is helpful in many real-life applications, such as weather forecasting, scientific research, and international travel. For instance, the Fahrenheit scale is commonly used in the United States, while Celsius is more widely used in most other countries.
