In Fahrenheit, what is the equivalent of -15 degrees Celsius?

• A. -20 degrees F
• B. 0 degrees F
• C. 5 degrees F
• D. 15 degrees F

Answer: (C)

To convert temperatures from Celsius to Fahrenheit, the formula used is: \[ F = \left( C \times \frac{9}{5} \right) + 32 \] In this case, we will substitute -15 degrees Celsius into the formula: \[ F = \left( -15 \times \frac{9}{5} \right) + 32 \] Calculating that step-by-step: 1. First, multiply -15 by \(\frac{9}{5}\): \[ -15 \times \frac{9}{5} = -27 \] 2. Next, add 32 to -27: \[ -27 + 32 = 5 \] This means that -15 degrees Celsius is equivalent to 5 degrees Fahrenheit. The positive 5 degrees Fahrenheit reflects the value obtained after applying the conversion formula correctly, indicating that this option is the right result. It shows how significant differences appear across the Celsius and Fahrenheit scales and solidifies the understanding of temperature conversion principles.

To convert temperatures from Celsius to Fahrenheit, the formula used is:

[ F = \left( C \times \frac{9}{5} \right) + 32 ]

In this case, we will substitute -15 degrees Celsius into the formula:

[ F = \left( -15 \times \frac{9}{5} \right) + 32 ]

Calculating that step-by-step:

1. First, multiply -15 by (\frac{9}{5}):

[ -15 \times \frac{9}{5} = -27 ]

2. Next, add 32 to -27:

[ -27 + 32 = 5 ]

This means that -15 degrees Celsius is equivalent to 5 degrees Fahrenheit. The positive 5 degrees Fahrenheit reflects the value obtained after applying the conversion formula correctly, indicating that this option is the right result. It shows how significant differences appear across the Celsius and Fahrenheit scales and solidifies the understanding of temperature conversion principles.
