A clock loses 5 seconds every 12 minutes. At this rate, how many minutes will the clock lose in a 24-hour period?

10 minutes

24h = 24x60min = 1440min

5 sec 12 min

x sec 1440 min

x = 1440*5/12 = 600 sec = 10 min

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

ou would have 12 of each
