A child has 4 wooden blocks. How many different ways can she stack 3 of them into a tower?

faltersainse [42]

Answer:

Step-by-step explanation:

To find the number of different ways she can stack 3 of them in a tower, we need to use the formula:

$_{n}P_{k}=\dfrac{n!}{(n-k)!}$

n = 4

k = 3

$_{n}P_{k}=\dfrac{4!}{(4-3)!}$

$_{n}P_{k}=\dfrac{4!}{1!}$

$_{n}P_{k}=\dfrac{4*3*2*1!}{(1)!}$

$_{n}P_{k}=\dfrac{4*3*2*1!}{1}$

$_{n}P_{k}=\dfrac{24}{1}$

Assume that y varies inversely with x. If y=12 when x=5, find y when x=3

NemiM [27]

Inversely variation means xy = c, where c is a constant

Since when y = 12 x = 5, then c = 12*5 = 60

So xy = 60

Now when x = 3, y = 60/3 = 20
