1 answer:
To solve this problem it is necessary to use the multiplication counting rule, that states that if there are two events a and b, the total number of outcomes will be a times b (a*b).
In this case, the total number of outcomes will be the product of the number of options for each event (cages, kinds of wood shavings and water bottles).
Baldwin's family can set up a home for their hamster in 20 different ways.

Answer:
280 ft squared
Step-by-step explanation:
To find the area of the nonshaded portion, we can find the area of the entire floor and then subtract the shaded area.
The total area is that of a rectangle: 30 * 15 = 450 ft squared.
Now, the shaded region is made up of a rectangle and a triangle.
- The rectangle has length 8 and width 10, so its area is 10 * 8 = 80 ft squared.
- The triangle has base 12 and height 15, so using the area of a triangle formula: (where b is the base and h is the height) = (12 * 15)/2 = 180/2 = 90 ft squared.
- The total shaded region is: 80 + 90 = 170 ft squared
Subtract 110 from 450: 450 - 170 = 280 ft squared.
Thus, the answer is 280 ft squared.
