Aperson came to work at 8: 30 am, went out at 11: 45 am, had lunch, came in at 12: 30 pm, and left at 5: 15 pm. how many hours did this person work?

Hello!

The person started working at 8:30 and stopped at 11:45 for lunch. That means that person worked 1 hour and 15 minutes before taking a lunch break.

The lunch break doesn't count because the person wasn't "working" then.

Next, this person worked from 12:30 to 5:15, which means they worked 4 hours and 45 minutes.

Add this up with the 1 hour and 15 minutes from before:

4 h 45 min + 1 h 15 min = 6 hours

This person worked a total of 6 hours.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
