Answer:

715 ways.

Step-by-step explanation:

We are asked to find the number of ways Rudy can choose 4 pizza toppings from a menu of 13 toppings if each topping can only be chosen once.

We will use combinations formula to solve our given problem.

The number of combination n chosen r at a time is given by formula:

C(n,r)=\frac{n!}{r!(n-r)!}

C(13,4)=\frac{13!}{4!(13-4)!}

C(13,4)=\frac{13!}{4!*9!}

C(13,4)=\frac{13*12*11*10*9!}{4*3*2*1*9!}

C(13,4)=\frac{13*11*10}{2}

C(13,4)=13*11*5

C(13,4)=715

Therefore, Rudy can choose 4 pizza toppings from a menu of 13 toppings if each topping can only be chosen once is 715 ways.

Ket [755]

Answer:

D.5

Step-by-step explanation:

You can write the following equations from the information given:

y=x+3 (1)

11x+5y=47 (2)

x is the number of hardback books

y is the number of paperback books

You can replace (1) in (2):

11x+5(x+3)=47

11x+5x+15=47

16x=47-15

16x=32

x=32/16

x=2

Then, you can replace the value of x in (1) to find the value of y:

y=2+3

y=5

According to this, the answer is that Jamal bought 5 paperback books.
