6bananas are to be selected from a group of 8. in how many ways can this be done

Your answer is 28.

Step-by-step explanation:

8C6 = 8!/(6!(8-6)!)

8*7*6*5*4*3*2*1/6*5*4*3*2*1*2*1

Eliminate 6*5*4*3*2*1 from the numerator and denominator.

8*7/2*1 = 56/2 = 28

101.08 degrees to nearest hundredth.

Step-by-step explanation:

Use the Cosine Rule:-

25.7^2 = 10.7^2 + 21.4^2 - 2*10.7*21.4 * cos x   where x is the required angle.

cos x =     (25.7^2 - 10.7^2 - 21.4^2) / (-2*10.7*21,4)

=  88.04 / - 457.96

= -0.192244

x = 101.08 degrees
