The ice and steam points of a certain thermometer are -20° and 100° respectively. Calculate the Celsius temperature corresponding to 70° on the thermometer
84.0o
75.0o
64.0o
58.0o
Correct answer is B
\(\frac{70 -(- 20)}{100 -(-20)} = \frac{\theta - 0}{100 - 0}\)
\(\theta = \frac{90 \times 100}{120} = 75^oC\)
