When using scientific notation, you only want one number to be in front of the decimal place. If you have to make the number smaller, then the 10^nth power will be positive. If you have to make the number bigger, then 10^nth power will be negative. Example:
0.54 --> 5.4 * 10^-1
35 --> 3.5 * 10^1
The value of n depends on how many spaces the decimal point needs to be moved. For your question, putting 23 in scientific notation would look like this:
23 --> 2.3 * 10^1
Answer:
C. 27.3%
Step-by-step explanation:
The total number of people who ordered a sundae is 22.
The number of those who got crushed candy is 6.
To find the percentage, divide the value (6) by the total value (22), and then multiply it by 100.
Thus, 6 is approximately 27.3% of 22.

An irrational number between -2 and -1 would be 
A rational number between -2 and -1 would be -1.5
Step-by-step explanation:
= -1.570796... This number does not have repeating decimals, patterns, and it isn't a terminating decimal. It is irrational.
-1.5 is a terminating decimal, therefore it is rational, as well as between -2 and -1.
