Answer:
5! (5 factorial) or 120 ways
Step-by-step explanation:
You can arrange P different ways. R can be arranged only 4 different ways because Pwill be in one of the spots. Next, you can arrange "I" 3 different ways because P and R are already arranged in 2 spots, meaning you cant put "I" there. Next, S can be arranged in 2 different ways for the same reason. And lastly, M can only be arranged in 1 different way because the other spots are taken.
You can put it in any order. For example, M could be arranged 5 ways and P could be arranged in 1 way. You will still get 120 ways
Hopefully this helped. The explanation might be a bit confusing but I tried my best. I'm not good with explaining my solutions but I always try
Answer:
23 and 4
Step-by-step explanation:
x-y=19
x+y=27
x=19+y
(19+y)+y=27
19+2y=27
2y=8
y=4
x-4=19
x=23
23+4=27
23-4=19
Answer:
The length of other wall is 3 meters.
Step-by-step explanation:
Given that:
Length of one wall = 4 meters
Length of diagonal from one corner to opposite corner = 5 meters
As the room is rectangular, the diagonal will form a right angled triangle.
The diagonal will be the hypotenuse.
Using pythagorean theorem;
Here,
a = 4 and c = 5
Taking square root on both sides
b = 3 meters
Hence,
The length of other wall is 3 meters.
Answer:
250
Step-by-step explanation:
Original cost * percent of the item = new price
Original *80% = 200
Change to decimal form
original *.80 =200
Divide each side by .80
original *.80/.80 = 200/.80
original =250
