The exact vaule of cos(247.5 degrees)

Leni [432]

$cos(247.5 deg)=cos( \frac{495deg}{2})
 = - \sqrt{ \frac{1+cos(495deg)}{2} } 
 = -\sqrt{ \frac{1- \frac{ \sqrt{2} }{2} }{2} } 
 = \frac{ \sqrt{2- \sqrt{2} } }{2}$

The Cooking Club made some pies to sell during lunch to raise money for an end-of-year banquet. The cafeteria contributed three

Alex73 [517]

7x13=91 meaning 13 pies were made in total. Since the cafeteria contributed 3 we can subtract 3 from 13. Ultimately meaning that the club contributed 10 pies.

The answer is 10.
