Answer:

45 is Composite!

Step-by-step explanation:

A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself. Every positive integer is composite, prime, or the unit 1, so the composite numbers are exactly the numbers that are not prime and not a unit. Hope this helps! :)

Definition: A prime number (or a prime) is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number.

45 = 9 x 5, so it is composite.

If the simple annual interest rate on a loan is 6, what is the interest rate in percentage per month?
zzz [600]

Answer:

0.5 %  

Step-by-step explanation:

 Annual rate = 6 %/yr

Monthly rate = ¹/₁₂ × 6 = 0.5 %/mo

If you invested $100 at 6 % annual simple interest, you would have <em>$106 </em>at the end of the year.

Simple interest is calculated only on the principal.

If the interest were calculated at 0.5 % monthly simple interest, you would get $0.50 at the end of each month. At the end of 12 mo, you would have <em>$106. </em>
