A thermometer with a percent error of 6.5% reads the room temperature as 68°F. what is the actual temperature in the room ?

Lynna [10]

Answer:

Actual temperature for the given temperature with thermometer with error of 6.5% is 63.8 degrees.

Explanation:

The percentage error in thermometer is 6.5% this means that if the temperature is 100 degrees the thermometer shell show 106.5 degrees. now calculating the actual temperature of the thermometer when the given temperature is 68°

Applying unitary method for solution 106.5

Then 100 will be $\frac {68}{106.5} \times 100$

= $0.6384 \times 100$

= 63.8 Degrees

On solving the value of this equation will give the actual temperature as 63.8 Degrees .
