ELEN [110]

Answer:

Temperature at midnight is -15.9 °F.

Step-by-step explanation:

Given: The temperature at noon was 43.6 °F. By midnight, the temperature has decreased by 15.3 degrees.

To find: The temperature at midnight.

Solution:

The temperature at noon was 43.6 °F.

Now, by midnight, temperature has decreased by 15.3 degrees.

So, first we need to convert the temperature in °F.

We know that, F=\frac{9}{5}C+32, where F is temperature in Fahrenheit and C is temperature in Celsius.

So, F=(\frac{9}{5} \times 15.3)+32  

\implies F=59.5

So, by midnight, temperature has decreased 59.5 °F

Therefore, temperature at midnight is 43.6-59.5=-15.9 °F

Hence, temperature at midnight is  -15.9 °F.
