Answer:

45 ways

Step-by-step explanation:

Combination method is appropriate for this question since it deals with arrangement.

i.e ^{n}C_{r} = \frac{n!}{(n - r)!r!}

Since 8 records are to be selected from 10 available records. Then, the number of ways for the arrangement of the records can be determined as;

Let n = 10 and r = 8

^{10}C_{8} } = \frac{10!}{(10 - 8)!8!}

       = \frac{10!}{2!8!}

       = \frac{10*9*8*7*6*5*4*3*2!}{2!8*7*6*5*4*3*2!}

       = \frac{10*9}{2}

       = 45

Therefore, the number of ways by which the records can be arranged is 45.

A pound of rice crackers costs $2.88. Matthew purchased 1/4 pound of crackers. How much did he pay for crackers?
Rom4ik [11]
He payed 0.72 
First you take 2.88, then you multiply it by 1/4 or a simpler way would be to divide 2.88 by 4. The answer is $0.72
