Question

Qual é o valor de -71,2 °C na escala Fahrenheit? (Com resolução)

Answer 1

formula de conversão de Celsius para Fahrenheit

c/5 = f-32/9

-71,2/5 = f-32/9

-14,24 = f-32/9 multiplicar cruzado

-128,16 = f -32

-128,16+32 = f

f = -96,16 °f

resposta

-96,16°f

Answer 2

Olá !


Resolução :


$\mathsf{\dfrac{TC}{5} =\dfrac{TF - 32}{9}} \\\\\\ \mathsf{\dfrac{-71,2}{5} =\dfrac{TF - 32}{9}} \\\\\\ \mathsf{\dfrac{-14,24}{1} =\dfrac{TF - 32}{9}} \\\\\\ \mathsf{ (TF - 32) = 9\cdot(-14,24)} \\\\\\ \mathsf{ (TF - 32) = -128,16} \\\\\\ \mathsf{ TF = -128 + 32} \\\\\\ \mathsf{ TF = -96,16}$



Resposta :


$\mathsf{~~A~~temperatura~~fahrenheit~~e~~-96,16~F~~}$
