Question

the table below compares the energy requirements of three display technologies for a reader device.
based on the table, imod technology is 179 times more energy efficient than lcd technology.
you may use the calculator.
type your answer to the box.

Explanation:

Step1: Convert battery life to hours

Since \(1\) day has \(24\) hours, the battery life of IMOD is \(5\times24 = 120\) hours, and the battery life of LCD is \(10\) hours.

Step2: Calculate the ratio

The ratio of energy efficiency (using battery - life as an indicator, longer battery - life means more energy - efficient) of IMOD to LCD is \(\frac{120}{10}=12\). So IMOD is \(12\) times more energy - efficient than LCD.

Answer:

\(12\)
