Question

as temperaturas : - 35° C e - 5°C correspondem em Fahrenheit respectivamente a ... ?

Com cálculos, por favor.

Answer 1

Olá!

-35 °C em °F

$\frac{Tc}{5} \ = \ \frac{TF \ - \ 32}{9}$

$\frac{-35}{5} \ = \ \frac{TF \ - \ 32}{9}$

$-7 \ = \ \frac{TF \ - \ 32}{9}$

-7 · 9 = Tf - 32

-63 = Tf - 32

Tf = -63 + 32

$\boxed{TF \ = \ -3 1^{o} F}$

* -5°C em °F

$\frac{Tc}{5} \ = \ \frac{TF \ - \ 32}{9}$

$\frac{-5}{5} \ = \ \frac{TF \ - \ 32}{9}$

$-1 \ = \ \frac{TF \ - \ 32}{9}$

-1 · 9 = Tf - 32

-9 = Tf - 32

Tf = -9 + 32

$\boxed{TF \ = \ 23^{o} F}$
