Question

calcule o valor de 40° c

nas escalas Celsius e fahrenheit​

Answer 1

Sabendo que:

Fahrenheit --> Celsius:

212°F 100°C

Tf 40°C

32°F 0°C

Fazemos:

$\frac{tf - 32}{212 - 32} = \frac{40 - 0}{100 - 0}$

$\frac{tf - 32}{180} = \frac{40}{100}$

$10 \times (tf - 32) = 4 \times 180$

$10tf - 320 = 720$

$10tf = 720 + 320$

$10tf = 1040$

$tf = \frac{1040}{10}$

$tf = 104$
