Yes. 55 is a composite number and it is divisible by 1, 5, 11, 55

27 and 55 are composite numbers but 13 is a prime number

55 is a composite number because it has other factors aside from 1 and itself. The other factors of 55 are 5 and 11.

No, 23 is not a triangular number. Here are a few examples of triangular numbers: 21, 28, 55, 45, 78 and 91.

55 has factors other than 1 and itself, so it is not a prime number. For example, 55 is divisible by 5. (You can tell this because the last digit is a 5. If the last digit - the digit in the ones place - is a 5 or a 0, the number is divisible by 5.) Therefore, 55 is a composite number.composite

Anything that isn't 1, 5, 11, 55

It has more than two factors.

21 miles / 55 mph = 0.38 hours, or 23 minutes

15, 49, 55, 87, 91,105 are the composite numbers.

composite because it has more than two factors

A composite number is a number which is not prime. All numbers are divided into the categories of either prime or composite (except for the number 1, which is neither). Examples of composite numbers are: 4,6,8,10 etc. All even numbers and square numbers are composite. There are, however, odd and non-square numbers that are composite as well, such as 15,21,27 and 55.

The composite factors of 1485 are 9, 15, 27, 33, 45, 55, 99, 135, 165, 297, 495, 1485

yes it is. - turtles rock man :-)

110 is composite. A prime number is a number that is divisible only by 1 and itself; it has no other factors. A composite number is a number that is divisible by more than 2 numbers. The factors of 110 are 1, 2, 5, 10, 11, 22, 55, and 110. Therefore, 110 is a composite number.

Composite 55 / 11 = 5

34+21 = 55 and 70-21 = 55

Answer:55 is not a prime number. It is a composite number.Definition:A prime number has exactly two factors: 1 (also known as unity) and itself. A composite number has more than two factors; in other words, it has at least one factor besides 1 and itself.Explanation:Any number ending in 0 or 5 is evenly divisible by 5, so it has 5 as a factor. Thus, 55 is also divisible by 5, so it is a composite number.

Every number greater than 5 that ends in a 5 is a composite number, not a prime.

A "one step palindrome is "any number can be changed into a palindrome number by reversing the digits and adding to the original number" one time. For example, the number 23 can be turned into a palindrome in just one step: 23 + 32 = 55 The same goes for the number 12: 12 + 21 = 33

Prime numbers are numbers that can only be multiplied itself and one.For ex.87 is a prime number. You can't multiply a number to get 87. Composite is a number that can be multiplied by other numbers than itself. For ex.55 is a commposite number. 11 and 5 can get you 55. Hope u understand! Good luck!

It ends with a 5 and so is evenly divisible by 5.

Prime factorization means to change a composite number into the product of its prime factors as for example 55 as a product of its prime factors is 5*11 = 55

The numbers 9, 15, 21, 25, 27, 33, 35, 39, 45, 49, 51, 55, 57, 63, 65, 69, 75, 77, 81, 85, 87, 91, 93, 95 and 99 are the odd composite numbers less than 100.

55 + 23 = 78

78-55 = 23
