An rational number, is a real number, that can be written in the form of p/q, where q is not equal to 0 or 1. A common misconception is that irrational numbers do not terminate; this is false. For example, 1/3 equals 0.3 repeating, but 1/3 can be written as p/q. As you can infer, an irrational number is a number, that cannot be written as p/q. One example is pi, or e.

Alisiya [41]

The commission would be $2095.

Step-by-step explanation:

Given,

Commission on first $1000 = 7%

Amount of commission = 0.07*1000 = $70

Worth of sold items = $14,500

We will subtract $1000 from it.

Balance = 14500-1000 = $13500

Commission on balance = 15% = 0.15

Amount of commission = 0.15*13500

Amount of commission = $2025

Total commission = 70+2025 = $2095

The commission would be $2095.

Convert 1.50 micrometers^2 to m^2. Show your solution.

Vadim26 [7]

Here is the solution for the problem:

1m * 1m = 1m² 
1m = 1,000,000µm = 1 x 10^6µm 
1 x 10^6µm * 1 x 10^6µm = 1m² 
1x10^12µm² = 1m² (Now, divide both sides by 1x10^12). 
1x10^12µm² / (1 x 10^12) = 1m² / (1 x 10^12) 
1µm² = 0∙000 000 000 001 m² (x both sides by 1.5). 
1.5µm² = 0∙000 000 000 0015 m² 
1.5µm² = 1∙5x10^-12 m²

So 1.50 micrometers^2 is equal to 1.5 x 10^-12 m². I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.
