The number of quasi-prime numbers that are less than 500 = 92
<h3>What are quasi-prime numbers?</h3>
Quasi-prime numbers are those numbers that are also known as semi prime numbers which can not be divided by 2,7 or 11.
They are often derived from prime numbers which are 95 in number from 2 - 499. ( less than 500).
The 95 prime numbers - 3 numbers( such as 2,7 or 11) = 92
Therefore, the number of quasi-prime numbers that are less than 500 = 92

Answer:
A. Rational number
Step-by-step explanation:
It is not a whole number or integer because it's a fraction. so it's the rational of a whole number.
Answer:
Here's how to do it.
Step-by-step explanation:
The two triangles must be similar, that is, corresponding angles must be equal, as in the diagram below.
1. Find a corresponding pair of sides
Assume that ∆ABC is the original and ∆DEF is its scaled image.
Then, AB and DE are corresponding sides, with lengths of 8 and 12 units , respectively.
2. Set up a ratio
Ratio = side length in image/side length in original = 12/8
3. Simplify the ratio
The simplified ratio is the scale factor (SF).
SF = 12/8 = 3/2 = 1.5
The scale factor is 1.5.
