Final answer:
To convert temperature from Fahrenheit (°F) to Celsius (°C), you can use the formula: C = (F - 32) × (5/9). Given the starting temperature of 8°C, which is equal to 46.4°F, and a decrease of 8°C, we can determine that the temperature has decreased by 70.4°F on the Fahrenheit scale.
Step-by-step explanation:
To convert temperature from Fahrenheit (°F) to Celsius (°C), you can use the formula:
C = (F - 32) × (5/9)
Let's apply this formula to the given question. The starting temperature is 8°C, which is equal to 46.4°F in Fahrenheit. If the temperature falls by 8°C, we need to find the corresponding change in Fahrenheit. Using the formula, we have:
- Starting temperature in Fahrenheit: F = 46.4 + 32 = 78.4°F
- Temperature change: F - 8°C = 78.4 - 8 = 70.4°F
Therefore, the temperature decrease of 8°C is equivalent to a decrease of 70.4°F on the Fahrenheit scale.
