Answer:
Scale factor to transform rectangle A into rectangle B is 
.
Explanation:
If both rectangles are similar, then scale factor for width (
) and height (
), no unit, must be the same. That is:
(1)
Where:
- Widths of rectangles A and B, no unit.
- Heights of rectangles A and B, no unit.
Let suppose that width is parallel to x-axis, whereas height is to y-axis. If we know that 
, 
, 
and 
, then we have the following result:
Which algraically consistent and hence we conclude that scale factor to transform rectangle A into rectangle B is .
Answer:
Potentially flammable.
Explanation:
You should add activated carbon to a cool solution then heat the mixture to boiling rather than add the carbon to the boiling solution.

5 is the answer to your question
Answer:
b. The number of digits in a randomly selected row until a 3 is found.
Explanation:
A random variable often used in statistics and probability, is a variable that has its possible values as numerical outcomes of a random experiment or phenomenon. It is usually denoted by a capital letter, such as X.
In statistics and probability, random variables are either continuous or discrete.
1. A continuous random variable is a variable that has its possible values as an infinite value, meaning it cannot be counted.
2. A discrete random variable is a variable that has its possible values as a finite value, meaning it can be counted.
Also, any random variable that meets certain conditions defined in a research study.
Hence, an example of a geometric random variables is the number of digits in a randomly selected row until a 3 is found.
