If the reindeer do not fight, there are 5!=120 ways to line them up in a straight line.
Out of these, Bloopin and Rudy are together in 4!=24 times.  Similarly Rudy and Bloopin will be together 4!=24 times.  So the number of ways they are not together is 120-24-24=72 ways.

Wendy wants to put a wallpaper border around her bedroom. The room has two walls that each measure 10 feet 5 inches and two wall
alisha [4.7K]

Answer: The correct answer is 11 yards of wallpaper border.

Step-by-step explanation: What Wendy needs to do is to calculate the perimeter of her bedroom. The perimeter of any given figure is simply a calculation of the entire measurement all around the given figure. In other words, the perimeter of Wendy's room denotes the addition of all the four side lengths of her bedroom.

The room has two sides both measuring 10 feet 5 inches. This gives a total of 20 feet 10 inches. It also has the other two sides both measuring 6 feet 1 inch and that too gives a total of 12 feet 2 inches. Adding them all together results in 32 feet 12 inches. Better still, the perimeter of the room is derived as;

Perimeter = 2 (L + W)

Perimeter = 2 (10'5" + 6'1")

Perimeter = 2(16'6")

Perimeter = 32'12"

Having in mind our conversion rate of 12 inches equals 1 foot, the results can be properly expressed as 32 feet plus 1 foot which gives us 33 feet.

If the perimeter of Wendy's room is now given as 33 feet, the conversion rate between feet and yards can now be applied. Having been given that

3 feet = 1 yard

Then 1 yard = 3 feet/3, that is

y = 3/3

Hence,

y = 33/3

y = 11

The results show that Wendy would needs to buy a total of 11 yards of wallpaper border.

A travel trailer is bought at the price of $35,000. The price decreases at the rate of .25 every year (t). The exponential expre
Debora [2.8K]

Answer:

$ 8300 (Approximately)

Step-by-step explanation:

Given:

Initial price of the trailer is, P_0=\$35000

Rate of decrease per year is, r=0.25

The time in years is, t=5

The exponential expression for the decrease in price after 't' years is given as:

P=P_0(1-r)^t

Plug in all the given values and solve for 'P'. This gives,

P=35000(1-0.25)^5\\P=35000(0.75)^5\\P=35000(0.2373)\\P=\$8305.5\approx \$8300

Rounding it to the nearest whole number, the price of the travel trailer after 5 years is $ 8,300.
