Question

convert 66°f to degrees celsius.
if necessary, round your answer to the nearest tenth of a degree.
here are the formulas.
$c = \frac{5}{9}(f - 32)$
$f = \frac{9}{5}c + 32$
$66°f = square°c$

Explanation:

Step1: Substitute \( F = 66 \) into the formula \( C=\frac{5}{9}(F - 32) \)

\( C=\frac{5}{9}(66 - 32) \)

Step2: Calculate the value inside the parentheses

\( 66-32 = 34 \), so \( C=\frac{5}{9}\times34 \)

Step3: Perform the multiplication

\( C=\frac{170}{9}\approx18.9 \)

Answer:

\( 18.9 \)
