Question

Your friend is traveling in Asia and tells you that the temperature is 29∘. You think that is a pretty cold temperature until you remember that she probably meant 29∘ Celsius. Convert 29∘ Celsius to Fahrenheit by using C=59(F-32). Round to the nearest whole number.

Answer 1

Given:

There are given the formula to convert the Celsius to Fahrenheit.

$C=\frac{5}{9}(F-32)$

Explanation:

According to the question:

We can see that in the question:

There is given one number that converts into the Fahrenheit

So,

Put 29 degrees for C into the given formula.

So,

$\begin{gathered} C=\frac{5}{9}(F-32) \\ 29=\frac{5}{9}(F-32) \end{gathered}$

Then,

$\begin{gathered} 29=\frac{5}{9}(F-32) \\ (29)9=5(F-32) \\ 261=5(F-32) \end{gathered}$

Then,

$\begin{gathered} 261=5(F-32) \\ 261=5F-160 \\ 5F=261+160 \\ 5F=421 \end{gathered}$

Then,

$\begin{gathered} 5F=421 \\ \frac{5F}{5}=\frac{421}{5} \\ F=84.2^{\circ} \\ F=84^{\circ} \end{gathered}$

Final answer:

Hence, the correct option is B.
