Question

Did you know that the outdoor temperature can be found by counting the chirps made by crickets?

According to the Farmer’s Almanac, the formula C = StartFraction n Over 3 EndFraction + 4 relates degrees celsius (C) to the number of cricket chirps (n) in 25 seconds.

One night while camping, Charlie counts 51 chirps in 25 seconds.


What is the temperature in degrees Celsius?

Answer 1

To find the temperature in degrees Celsius using the formula \( C = \frac{n}{3} + 4 \), we need to substitute \( n \) with 51, which is the number of chirps counted.

Plugging in the value:

\[
C = \frac{51}{3} + 4
\]

Now, calculate \( \frac{51}{3} \):

\[
\frac{51}{3} = 17
\]

Now add 4 to this result:

\[
C = 17 + 4 = 21
\]

Thus, the temperature in degrees Celsius is:

\[
\boxed{21}
\]
