Which is a true statement about the number 1? one is a factor of every whole number since every number is divisible by itself. one is not a factor of any number because it is neither a prime number nor a composite number. one is a prime number because it has less than two factors. one is a composite number because it has more than two factors.

One is a factor of every whole number since every number is divisible by itself.

Step-by-step explanation:

One is a factor of every whole number since every number is divisible by itself.

Step-by-step explanation:

The correct statement is - One is a factor of every whole number since every number is divisible by itself.

Few things to know about number 1.

1 is its own and only positive factor. Hence, 1 is neither prime nor composite.

1 is not a prime number. A number is called prime, if it has exactly two positive factors, 1 and the number itself. But for 1 its the same single number. That is why it is not prime.

1 is the common factor of every number as if it is not divisible by any number, it is divisible by itself. And this produces 1. Like the number 23. Its divisible by 23. So, 23/23 = 1

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
