Math for - Loops (Continuation)

  1. An automated bottling machine fills 12 bottles per minute. How many bottles does it fill in 5 minutes?

  2. A quality control system inspects pixels on a small display. The display area being checked has 8 rows of pixels and 10 pixels in each row. How many pixels are inspected in total?

  3. A counter starts at 1 and increases by 3 at each step.

    1. What are the first 5 numbers the counter displays?

    2. What is the sum of these 5 numbers?

  4. A value is repeatedly multiplied by 2, starting with the number 3. What is the value after 4 such multiplications?

  5. A sensor checks the temperature every hour for a total of 10 hours.

    1. If the temperature is above $25^\circ\text{C}$, it records a 'High'. If it's $25^\circ\text{C}$ or below, it records a 'Normal'. If 6 readings were 'High' during the 10 hours, how many readings were 'Normal'?

    2. If each 'High' reading triggers an alarm that sounds for 2 seconds, and 'Normal' readings do not trigger any alarm, what was the total duration the alarm sounded over the 10 hours?
