Respuesta :
45.7 °F is the Fahrenheit scale reading equal to 3 times that of the Celsius
-4 °F is 1/6 times that of the Celsius
Evaluating :
The relationship between temperature in degrees Fahrenheit, F, and degrees Celsius, C, is
F = 1.8°C + 32
Part a.
If F = 6°C, then
6°C = 1.8°C + 32
6°C - 1.8°C = 32
4.2°C = 32
C = 7.62
Therefore, F = 6×7.62 = 45.71
= 45.7 °F (nearest tenth)
Part b.
When F = (1/5)C, then
0.2°C = 1.8°C + 32
0.2°C - 1.8°C = 32
-1.6°C = 32
C = - 20
Therefore, F = 0.2 × -20 = -4
= -4 °F
What are Celsius and Fahrenheit scales?
Celsius and Fahrenheit are two scales won't to measure temperature. The temperature within the centigrade scale will be expressed in degrees Celsius. The temperature within the Fahrenheit scale will be expressed in degrees Fahrenheit. The relation between Celsius and Fahrenheit is proportional.
