Janey like to sleep for 9 hours 45 mins every night. On Monday she needs to be in bed to wake up at 7.25am what time does she need to be in bed!

In a certain pentagon, the interior angles are a, b,c, d,e where a, b,c, d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1

Is the square root of 4 plus the square root of 16 rational?
