current rules for telephone area codes allow the use of digits 2-9 for the first digit and 0-9 for the second and third digits. how many different area codes are possible with this rules? That same rule applies to the exchange number. which are the three digits immediately preceding the last four digits of a phone number. Given both of those rules, how many 10- digit phone numbers are possible? given that rules apply to the United States and Canada and a few islands, are there enough possible phone numbers? (assume that the combined population is about 400,000,000.
Answers
8*10*10 * 8*10*10 * 8*10*10*10 = 8^3 * 10*7= 512 * 10^7= 5.12 * 10^9
If you convert 400,000,000 into the scientific form it will become 4* 10^8. Since 5.12*10^9 > 4 * 10^8, then it is clear that the number should be enough
Final answer:
There are 800 possible area codes and exchange numbers each, following the given digit restrictions. The total number of unique 10-digit phone numbers given these rules is 6,400,000,000, which is sufficient considering a population of about 400,000,000.
Explanation:
The question addresses how many different area codes and phone numbers are possible given certain digit restrictions for both the United States and Canada. For the area code, the first digit can be any from 2 to 9, which gives us 8 possibilities, and the second and third digits can be any from 0 to 9, which provides 10 possibilities each. Therefore, the number of different area codes is 8 × 10 × 10 = 800.
Applying the same rules to the exchange number, which also has three digits, we have another 800 possibilities. Considering there are 10,000 combinations for the last four digits (from 0000 to 9999), we can calculate the total number of unique 10-digit phone numbers by multiplying the possibilities for the area code, exchange number, and the last four digits: 800 × 800 × 10,000 = 6,400,000,000 possible phone numbers.
Since the combined population of the United States, Canada, and a few islands is about 400,000,000, this amount of possible phone numbers is more than sufficient to provide a unique phone number for every individual.

write a problem multiplying a 3-digit number by a 2-digit number. Show all steps to solve it by using place value and regrouping and by using partial products.
Answers
By breaking down each number into its place value parts, performing six separate multiplications, and then adding those products together, you can multiply a three-digit number by a two-digit number.
Explanation:The multiplication of a three-digit number by a two-digit number can be accomplished via place value and partial products. To illustrate, consider multiplying 123 by 25. Begin by breaking down 123 into 100 + 20 + 3 and 25 into 20 + 5.
Next, multiply each part of the three-digit number by each part of the two-digit number, which gives us 100 * 20, 20 * 20, 3 * 20, 100 * 5, 20 * 5, and 3 * 5. When you add these six products together, you get: 2000 + 400 + 60 + 500 + 100 + 15 = 3075, which is the result of 123 * 25.

A (1+0.06)15
B 1+0.06(15)
C15+0.6(15)
D15 + 0.06
Answers
Answer:
A is correct
Step-by-step explanation:
Marshall bought some pet supplies for $15
The sales tax was 6%
Expression: 1.06(15)
Cost of pet = $15
Sale tax = 6% of 15
= 0.06×15
Total cost after sale tax = 15 + 0.06×15
Take out 15 common = (1+0.06)15
The given expression is equivalent to (1+0.06)15
1.06(15) = (1+0.06)15
Using (1+0.06)15 to find total cost.

Answer:
[tex]2d+35[/tex]

The sum of two consecutive even integers is 218. What are the integers
Answers
They are consecutive even numbers.
If you combined them, you'd get 218.
The required two consecutive even integers that add up to 218 are 108 and 110.
What are integers?Integers are numbers that can be written without a fractional or decimal component, such as -3, -2, -1, 0, 1, 2, 3, and so on. They include the positive whole numbers (1, 2, 3, etc.), the negative whole numbers (-1, -2, -3, etc.), and zero.
To find the two consecutive even integers that add up to 218, we can use algebra.
Let's represent the first integer "x".
Since it is even, we know that it can be divided by 2 with no remainder.
Since it is also consecutive to the second integer, we can say that the second integer is "x + 2".
We can set up the equation:
x + (x + 2) = 218
Simplifying, we get:
2x + 2 = 218
2x = 216
x = 108
So the two consecutive even integers that add up to 218 are 108 and 110.

an appliance store sells a washer dryer combination for $1500 if the washer costs $200 more than the dryer find the cost of each appliance.
Answers
X+X+200=1500
Isolate the variable
2x=1300
X=650
Know that we know what X is, we know that X + 200 will equal the cost of the second appliance
650+850=1500
To find the cost of the washer and the dryer when the total cost is known along with the difference in their costs, we used a simple algebraic method of solving equations to determine that the dryer costs $650 and the washer costs $850.
Explanation:The question involves solving a system of linear equations to find the cost of two items whose total and difference in cost are known. To find the cost of each appliance, let's denote the cost of the dryer as x dollars. According to the problem, the washer costs $200 more than the dryer, so the washer's cost would be x + $200. The total cost of both appliances is $1500.
We can set up the following system of equations:
x + (x + 200) = 1500Solving the equations, we combine like terms:
2x + 200 = 15002x = 1300x = 650Now we know the dryer costs $650 and the washer costs $650 + $200 = $850.

First, lets find the number of gallons needed for 2727 miles. We can do this by dividing the miles by the miles per gallon, this way we have an number in gallons. So...
2727 / 27 = 101Gallons
Now, we know we need 101 gallons, and since each gallon is 4.04, we can find how much it is, by multiplying the amount times the number needed So...

Abe is going to plant 54 oak trees and 27 pine trees. Abe would like to plant the trees in rows that all have the same number of trees and are made up of only one type of tree. What is the greatest number of trees Abe can have in each row?
Answers
Answer with explanation:
Number of oak trees =54
Number of pine trees =27
→Abe would like to plant the trees in rows that all have the same number of trees and are made up of only one type of tree.
We, will take H CF that is highest common factor of 54 and 27.
54 = 2×3×3×3
27=3×3×3
→H CF(54,27)=3 × 3×3=27
So, greatest number of trees Abe can have in each row =27,and there will be maximum of 3 rows, 2 containing oak tree because [tex]\frac{54}{27}=2[/tex], and one containing pine tree because[tex] \frac{27}{27}=1[/tex].
