SO... I believe if I understand the question that he drive to work 5 times a week w/ 7 gallons round trip. 5x7= 35 miles; now, since there saying in a month i will have to assume there a four weeks per month. so 35 miles per week x 4 weeks = 140 miles. then they say you also drive and extra 25 miles during this period bringing you to a grand total of 165 miles.

So what i did was knowing the cost would be 3.15 for every 20 miles for every gallon, I found out what 5 miles would cost instead of 20 -- 25% of 3.15 = $0.7875 . 165 miles x $0.07875 = total of $129.9 I believe this to be correct, however i'am not positive. hope this helps

sound is invisible, but sometimes we can feel it. when a kettle-drum is thumped with a stick that time the tight drum skin moving up and down very quickly for some time and then it pumped sound waves into the air. loudspeakers also work in a similar manner.

components of a speaker:

electromagnet

in order to translate an electrical signal into an audible sound, an electromagnet is used in looudspeakers

suspension

suspension is used to center the voice coil in the gap of the magnet and it exerts a restoring force to keep it there. suspension is used to limits the maximum mechanical excursion of the diaphragm and voice coil.

voice coil

voice coil is a coil of wire which is attached to the apex of a loudspeaker cone. it provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.

cone

in a loudspeaker, a thin, semi-rigid membrane attached to the voice coil, which moves in a magnetic gap due to which it vibrates and produced sound. it is known as diaphragm and it can also be called a cone, though not all speaker diaphragms are cone-shaped.

surround

surround is also known as front suspension. surround is used to join the cone to the chassis. together with the suspension it controls the cone excursion, and it is also used to determine how energy which is travelling through the cone is absorbed, and how the speaker limits when it reaches the ends of its travel.

dustcap

dustcap is used to protect the voice coil from dust and dirt. it is a part of the cone.

how speaker work

the outer part of the cone is fastened to the outer part of the loudspeaker's circular metal rim. the inner part is fixed to voice coil that sits just in front of a permanent magnet . when loudspeaker is hooked up to a stereo, electrical signals feed through the speaker cables into the coil. it will convert the coil into an electromagnet magnet . when electricity flows back and forth in the cables, the electromagnet either repels or attract the permanent magnet. this moves the coil back and forth, and it pull and push the loudspeaker cone. like a drum skin vibrating back and forth, the moving cone pumps sounds out into the air.in this way loudspeakers works.

Answer:

the correct answer is economics is a game without winners or losers.

explanation:

unlike sports or games economic is a game without losers or winner rather it is a game where everyone wins. parties of business doing businesses exchange money with each other and hence exchange is done on the basis of goods. one party takes the goods and other sales it so there is winner on both sides. each party values more highly the good it gets than the good it gives up. both sides exchange only because both intend to increase their value. so there is no concept of lose or win.

Peppy knows a lot about marketing, but not much about the legal or financial aspects of starting a new business. he wants to consult with a lawyer and accountant, but his budget is tight with all of the expenses involved in getting peppy's pizzazzeria up and running. peppy should: trust his basic instincts and try to put it together without the advice of lawyers and accountants. delay talking with a lawyer and accountant until the business has established a positive cash flow for at least one year. immediately hire full-time lawyers and accountants for his staff. consult with a lawyer and accountant even though the budget is tight.
