Question

3- Transformar em graus Celsius:
a) 14 °F
b) 104 F
d) 41°F
d) 126 °F
​

Answer 1

a)Tc/5 = 14 - 32/9

Tc/5 = -18/9

9Tc = -90

Tc = -90/9

Tc = -10°C

b)Tc/5 = 104 - 32/9

Tc/5 = 72/9

9Tc = 360

Tc = 360/9

Tc = 40°C

c)Tc/5 = 41 - 32/9

Tc/5 = 9/9

9Tc = 45

Tc = 45/9

Tc = 5°C

d) Tc/5 = 126 - 32/9

Tc/5 = 94/9

9Tc = 470

Tc = 470/9

Tc ≅ 52,33°C
