What is the multiplicative identity of -12/13

Nata [24]

Answer:

The number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.

Therefore, option (B) is true.

Step-by-step explanation:

We know that when a number let say 'n' get multiplied by '1', it remains unchanged.

i.e.

n × 1 = n

1 × n = n

The number '1' is called the 'multiplicative identity' of a number 'n' because it does not change the number 'n' after getting multiplied by it.

Given the number

-12/13

Multiply the number '-12/13' by '1'.

i.e.

-12/13 × 1 = -12/13

1 × -12/13 = -12/13

Thus, the number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.

Therefore, option (B) is true.

a leaky faucet is losing water and it is filling a 5 gallon bucket every 12 hours. At the rate, how many gallons of water will t

Alina [70]

Answer:

20 gallons

Step-by-step explanation:

First start off by dividing 48 by 12 to see how many times 12 goes into 48.

48 / 12 = 4

now that you know that 12 goes into 48 4 times, multiply 4 by 5 to see how many gallons the leaky faucet will fill in 48 hours.

4 x 5 = 20

therefore the answer is 20 gallons

I hope this helps ^^

Seven people are in an elevator which stops at ten floors. In how many ways can they get off the elevator?

zlopas [31]

The number of ways people can get off the elevator is 604800 ways.

In this question,

Number of people, n = 7

Number of floors, r = 10

The first person can leave elevator in one of 10 ways. Then second person has to choose from one of remaining 9 floors. Then third person in 8, fourth in 7 ways and so on.

Number of ways people can get off the elevator can be calculated as

⇒ $nP_r=\frac{n!}{(n-r)!}$
