    A number t is no less than 30 and fewer than 40.

    This is a compound inequality. Take it in 3 parts:

    Step 1: fewer than 40 means less than (does not include 40)
    t < 40

    Step 2: no less than 30 means greater than or equal to
    t >= 30

    Step 3: Combine these 2 statements into one compound inequality:
    30 <= t < 40
