There are a total of 20,000 available numbers. To ascertain how many phone numbers are available, the number of digits in each number must be known. Here, I will assume each number has 7 digits. This leads to the format starting with either 373XXXX or 377XXXX, where each X can be any digit from 0 to 9. This results in 10 options for each X. Therefore, there are 10×10×10×10 = 10,000 distinct phone numbers starting with 373 and another 10,000 with 377, totaling 20,000 numbers.
Response:
1. Closure
2. Distributive
3. Closure
Detailed explanation:
In this scenario, we are examining the properties that each equation demonstrates.
The first equation shows the closure property.
This indicates that whether we add in one direction or the other, the result remains unchanged. Therefore, we conclude that addition conforms to the closure property in this case.
The third equation also shows the closure property. Regardless of how we approach the addition for this equation, the outcome remains consistent.
The second equation displays the distributive property.
Each element within the parentheses is multiplied by the negative sign before we proceed with further calculations.
Answer:
Step-by-step explanation:
The present value of the house is $120,000 and the interest rate is 5.5%, or 0.055.
We will utilize the following equation:
where 
represents the present value, 
symbolizes the interest rate, and 
refers to the number of years.
