1. A. There are 8 service codes such as: 211, 311, 411, 511, 611, 711, 811, and 911.

B. There are 72 total ERC (not including service codes). 8 * 10 = 80 – 8 = 72 service codes. The 8 represents the service codes multiplied by the 10 digit number then I subtracted the 8 service codes since it was not including them.

C. There are 5 toll free numbers such as: 800, 855, 866, 877, and 888.

D. There are 50,000,000 toll free phone numbers (without restrictions). I multiplied the 5 toll free numbers by 10 to the 7th power, since there is no restrictions on the number with 10 digits then raised to the 7th power because of the 7 digit phone number.

2. There are 144 area codes that were available prior to 1995. 8*2*10=160-16=144. I multiplied 8 for the service codes by 2 for the 0 and 1, by 10 for the digits. Then subtracted 16 for codes prior to 1995.

3. There are 656 additional area codes that became available after the middle digit restrictions were removed. 8*10*10=800-144=656. I multiplied 8 for the service codes by 10 for the middle number since it opened up, then by 10 for the digits which equaled 800, then subtracted the 144 that was already available found in answer 2.

4. If you make 0 and 1 available it would increase the available number of phone numbers by 344. 10*10*10=1000-656=344. I took the 10 for the first set in a number and multiplied it by 10 for the middle numbers, then by 10 for the last set of numbers and got 1,000. Then subtracted the 656 additional area codes that became available.

5. There are 8,000,000 phone numbers available in each area code of TV land. 800*1*1*1*10*10*10*10=8,000,000. I multiplied 8 for the service codes by 10 for the middle number since it opened up, then by 10 for the digits which equaled 800. Then multiplied that by 1*1*1 representing the “555”, then multiplied that by 10*10*10*10 representing the last 4 digits of the phone number.

...Santoro, A. (2004). “Manipulatives: A Hands-On Approach to Math.” Principal, 84 (2), (28-28).
This article speaks about the importance and significance of the use of manipulatives in the classroom, specifically in the subject of math. Manipulatives have proven to be valuable when used in a math class and are even more valuable to the children when they are young, and are learning new math concepts. Students are able to physically...

ANALYSIS
Physics has a lot of topics to cover. In the previous experiments, we discussed Forces, Kinematics, and Motions. In this experiment, the focus is all about Friction. Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction like fluid friction which describes the friction between layers of a viscous fluid that are moving relative to each other; dry friction which...

The case between Beauty and Stylish involves concept of a valid contract, pre-contractual statements, express term and misrepresentation.
A valid contract is established between Beauty and Stylish when an offer is accepted and there is intention for both parties to create legal relations. An offer refers to the expression of willingness of the offerer to be contractually bound by an agreement if his or her offer is properly accepted. It has to be clear and certain in terms. It must also...

Four Decades of the Defence of
Australia: Reflections on Australian
Defence Policy over the Past 40 Years
Hugh White
The serious academic study of Australian defence policy can be said to have
begun with the publication of a book by the SDSC’s founder, Tom Millar, in
1965. The dust jacket of that book, Australia’s Defence, posed the following
question: ‘Can Australia Defend Itself?’ Millar thus placed the defence of Australia
at the centre of his (and the SDSC’s) work...

My Math Experience
When I was younger math was my favorite subject, it was something that I felt very confident
with. Unlike english, history, and literature, where I had to exert extra effort, math was the only
subject that really came naturally to me. I remember when I was a kid my dad would test me on ...

• How did different groups of Americans respond to those changes and how effective were their responses?
• What role did government play in these developments?
In the late 1900s some of the most social and economic developments were railroads, steel oil, the type writer cash register, light bulb and agriculture. The development of the railroad made it easier for immigrant to...

...what is 1+1 and your answer, or course, is going to be 2. But what if God responded to that elementary question with the answer of 3? Would you question it? Or would you take His answer as-is because He is all knowing? I am going to explore through math whether or not we, as Christians, it is wrong to question God.
