Question

Plant experts advise that gardenias kept indoors must have high humidity, plenty of sunlight during the day, and cool temperatures at night. The recommended nighttime temperature range in degrees Fahrenheit is 60 degrees ≤ F ≤ 65. Given that C = (5/9)(F-32), express the corresponding temperature range in degrees Celsius.

a. 15.6°C ≤ C ≤ 18.3°C
b. 10.0°C ≤ C ≤ 15.0°C
c. 20.0°C ≤ C ≤ 25.0°C
d. 25.6°C ≤ C ≤ 30.3°C

Answer 1

The recommended nighttime temperature range for gardenias in degrees Celsius is approximately 15.6°C to 18.3°C, calculated using the conversion formula C = (5/9)(F-32). This corresponds to option (a).

Step-by-step explanation:

To convert the recommended nighttime temperature range for gardenias from degrees Fahrenheit to degrees Celsius, we can use the conversion formula C = (5/9)(F-32). Plugging in the Fahrenheit values, we get the following:

• For the lower limit of 60°F: C = (5/9)(60-32) = (5/9)(28) ≈ 15.56°C
• For the upper limit of 65°F: C = (5/9)(65-32) = (5/9)(33) ≈ 18.33°C

Therefore, the corresponding temperature range in degrees Celsius for gardenias kept indoors is approximately 15.6°C ≤ C ≤ 18.3°C, which matches option (a).
