Answer:
<h2>
66 different ways </h2>
Step-by-step explanation:
This is a combination question. Combination has to do with selection. For example if r objects are to be selected from n pool of oblects, this can be done in nCr number of ways.
nCr = n!/(n-r)r!
According to the question, if a radio show can only play 10 records out of 12 records available, this can be done in 12C10 number of ways.
12C10 = 12!/(12-10)!10!
= 12!/2!10!
= 12*11*10!/2*10!
= 12*11/2
= 6*11
= 66 different ways

Answer:
x = 10
Step-by-step explanation:
Consecutive angles in a parallelogram are supplementary, thus
∠ A + ∠ B = 180, substitute values
9x + 8 + 8x + 2 = 180, that is
17x + 10 = 180 ( subtract 10 from both sides )
17x = 170 ( divide both sides by 17 )
x = 10
w represents width
4w represents length
d represents diagonal
w2 + (4w)2 = d2
w2 + 16w2 = d2
17w2 = d2
±w√17 = d
The diagonal is the width times √17.
