Solution: Original area: \( 8 \times 15 = 120 \) m². New dimensions: \( 8 - 3 = 5 \) meters and \( 15 - 3 = 12 \) meters. New area: \( 5 \times 12 = 60 \) m². The decrease is \( 120 - 60 = 60 \) m². \boxed60Question: A geologist is studying the periodic patterns of seismic waves and notes that a specific wave pattern repeats every 24 seconds. If the current time is 2025-06-28 18:21:16, what is the smallest positive time (in seconds) after 18:21:16 when the wave pattern will repeat, such that this time is congruent to 6 (mod 11)? - go-checkin.com
