Average = Sum of numbers/ No. of numbers 45 + 25 + 35 = 105 105/3 = 35
The number halfway between 25 and 45 is the average of the two numbers. To find the average, you add the two numbers together and then divide by 2. In this case, (25 + 45) / 2 = 70 / 2 = 35. Therefore, the number halfway between 25 and 45 is 35.
135 is not prime. 135 = 3 * 3 * 3 * 5135 is a composite number because its factors are:1x1353x455x279x151, 3, 5, 9, 15, 27, 45, and 135.*NOTE: All numbers that have a 0 or a 5 in it are composite, except 5 because they will always have a third factor, 5.
To any set that contains it! It belongs to {30}, or {45, sqrt(2), 30, pi, -3/7}, or all whole numbers between 23 and 53, or multiples of 5, or square roots of 900, or composite numbers, or counting numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.

9, 15, 45 are the composite factors of 45.
Of these, 45 is the only composite number. All the others are prime.
9, 15, 45 are the composite factors of 45.
YES. 45 and 27 are composite numbers because they have other factors aside from 1 and themselves
Composite numbers between 35 and 45 are: 36, 38, 39, 40, 42, and 44.
31 is not composite.
23, 29 and 31 are prime. The rest are composite.
prime numbers have only factors of themselves and 1; therefore 45 is composite--it has factors of 1,3,5,9,15,45
45, 33 and 27 are composite numbers. 11 is a prime number.
The odd composite numbers are 9, 15, 21, 25, 27, 33, 35, 39, 45, 49, 51, 55, 57, 63, 65, 69, 75, 81, 85, 87, 91, 93, 95, and 99.Composite numbers are those numbers that can be expressed as the product of any two integers greater than 1. So they are all numbers that are not prime 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, 99.
45 and 51 are both composite numbers. This means they both have factors other than themselves and one.
