What is the elapsed time between 2: 16 a. m. and 8: 10 p. m.? a. 18 hr. 18 min. b. 17 hr. 54 min. c. 29 hr. 54 min. d. 22 hr. 18 min.

To solve the problem we can subtract the initial time from the final one and keep in mind that from x AM to x PM there are 12 hours. In our case we have: from 2:16 AM to 2:16 PM we get 12 hours. And now we can subtract 2:16 hours or 2*60 + 16 = 136 minutes from 8:10 hours or 8*60 + 10 = 490 minutes. Which gives us 490 - 136 = 354 minutes, or 5 hours and 54 minutes. Plus the other 12, it gives us 17 hours and 54 minutes. So the answer is B.

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
