Question

Calcule. qual é a temperatura na escala Fahrenheit corresponde a 40°C?
a)113.
b)4,444.
c)39,2.
d)2,25.
e)104

Answer 1

Tc / 5 = (Tf - 32) / 9 
40 / 5 = (Tf - 32) / 9 
8 = (Tf - 32) / 9 
Tf - 32 = 72 
Tf = 72 + 32 
Tf = 104°F
Tc = temperatura celsius
tf = temperatura fahrenheit

Answer 2

°F = (°C*1,8) + 32
°F = (40*1,8) + 32
°F = 72 + 32
°F = 104°F
