Answer:

86 books

Step-by-step explanation:

A stack of books is 43 inches tall.

Each book is \frac{1}{2} inch thick.

To find the number of books in tha stack, divide the height of the stack by the height of the book:

43:\dfrac{1}{2}

The division by the fraction \frac{1}{2} is equivalent to the multiplication by the fraction \frac{2}{1}, so

43:\dfrac{1}{2}=43\cdot \dfrac{2}{1}=43\cdot 2=86

What would be the total number of outcomes in each sample space?
Lerok [7]

Answer:

810

Step-by-step explanation:

In this case the sample space would be the number of combinations that can be made with the numbers from 1 to 30 with the letters of the alphabet, from "a" to "z", for example:

A1, A22, C4, F9, etc

Now we know how many numbers are 30, now the alphabet has 27 letters, therefore, the number of combinations are:

27 * 30 = 810

Which means that the total number of results is 810.
