How many different arrangements can be made using all the letters in the word topic

Mathematics

Goryan [66]3 years ago

The formula to find the permutations is nPr = \frac{n!}{(n-r)!}

Here n represents the total number of objects

r represents the number of objects taken at a time

The word TOPIC has 5 letters.

All the five letters are different.

And we need to take all 5 letters.

Hence n = 5 & r = 5

Number of arrangements = 5P5 = \frac{5!}{(5-5)!} =\frac{5!}{0!}  = 5!=120

120 different arrangements can be made using all the letters in the word TOPIC

A light flashes every 1 minute 15 seconds. another flashes every 1 minute 40 seconds. suppose they flash together at certain tim
ASHA 777 [7]

Answer:

5 minutes

Step-by-step explanation:

To get the response to this question, it would be required to convert both times to seconds alone.

For the first, the time It takes to flash is 1 minute 15 seconds which is same as 75 seconds

For the second, it takes 1 minute 40 seconds which is same as 100 seconds.

Now to get the time they would flash together, we need to know their lowest common multiples. The values involved are 75 and 100. Thus, the lowest common multiple of both is 300.

This is equivalent to 300 seconds which is 5 minutes time
