A clean rifle will shoot more accurately than a dirty one. There is no set time when your gun should be cleaned, but the general consensus is to clean it after you are done firing for the day, and before and after you put the gun in storage. Like dirty rifles, loose screws can cause a rifle to fire inaccurately.

Problem: Article: The limousine business isn't right for everybody. It is based on customer service and availability. If you're not a people person, look elsewhere. If you want a 9-5 job, think again. People rent limos at all hours of the day, and the most lucrative jobs take place on the weekends. Be sure you're comfortable with long, erratic hours before getting started in the business. If you want to start with your own car, insurance, and website, you're looking at $50-100,000, plus the monthly costs of gas and maintenance. If you're starting a virtual call center, with only business cards, a toll-free number, and a website, you can get started for anywhere from $500-5,000, depending mostly on how much you invest in your website. You don't even need a limousine to start a limousine company. Depending on how much you are willing to invest, you can start by building a customer base as a virtual call center, by buying a vehicle or two, or launching an entire fleet. Virtual Call Center All you need for this is a business card, website, and toll-free number. You will field calls or internet request for rides and subcontract them to limo services, taking up to a 20% commission. This is an inexpensive way to build a customer base and accrue capital. Drive A Vehicle You will need to start with a black sedan (usually a Town Car) and/or a limousine (white is preferable at first), both of which will require a significant investment. On the other hand, driving your own vehicle will allow you to increase your revenue substantially. Fleet Launching a fleet is the riskiest way to start your business, as it requires a large outlay of capital to purchase multiple sedans and limousines. You will also have to hire a dispatcher and chauffeurs, who will typically pay a flat fee to use lease your vehicles ($75-$150 a day) or give you a percentage of their fares (usually one third). More vehicles on the road can mean more money, but it can also mean bigger losses if business is slow. Whatever type of limousine service you decide to launch, your business will benefit from a strategic plan that will guide you in achieving your goals. You can find more details about how to write a plan here, but broadly, you will want to include: Your business concept: what you are offering, your strengths and weaknesses, long term goals, and performance indicators, beyond the bottom line, which will let you know you are succeeding or failing. These last might include important measures like the number of repeat customers and the number of inquiries you convert into sales. Market research: the nature of the industry, who are your customers (business men, airport traffic, weddings, etc), who are the other limousine companies you will be competing with, what prices are charged. Remember that the goal is to sell service. This is a luxury business; being the cheap limousine company is not a good business model. A marketing plan: how you will communicate with customers and grow your customer base. An operations plan: identify the individual projects that will lead to completing your larger goals. To begin with, these might include things like: hiring a designer, registering your domain, and finding a webhost all to build a website; or finding livery insurance, buying a car, and choosing billing options all to prepare your vehicle for service. Financial projections: these include a list of assets before you start the business; start-up costs such as building a website, getting insurance, obtaining permits, and purchasing a vehicle; marketing costs; and revenue projections. You will need to know how much business you need to do at what price in order to show a profit, and how long you can perform at a loss. You can find a sample business plan for a limousine service here. There are consultants who specialize in the limousine business. They can help you identify lucrative markets, set rates, and advertise effectively. Particularly if you are new to the business, a consultant can make you money in the long run, despite the initial cost.
Summary: Know what you're getting into. Consider the costs of starting a company. Decide the type of company you will start. Write a business plan. Consider hiring a consultant.

The formula is P=2l+2w{\displaystyle P=2l+2w}, where P{\displaystyle P} equals the perimeter of the rectangle, l{\displaystyle l} equals the length of the rectangle, and w{\displaystyle w} equals the width of the rectangle. This method will only work if you are given the perimeter and length of the rectangle. You might also see the formula written as P=2(w+h){\displaystyle P=2(w+h)}, where h{\displaystyle h} equals the height of the rectangle and is used instead of length. The variables l{\displaystyle l} and h{\displaystyle h} refer to the same measurement, and the distributive property dictates that these two formulas, although arranged differently, will give you the same result. Make sure you substitute for the correct variables. For example, if you are trying to find the width of a rectangle that has a perimeter of 22 centimeters, and a length of 8 centimeters, your formula will look like this:22=2(8)+2w{\displaystyle 22=2(8)+2w}22=16+2w{\displaystyle 22=16+2w} To do this, you need to subtract the length from each side of the equation, then divide by 2. For example, in the equation 22=16+2w{\displaystyle 22=16+2w}, you would subtract 16 from each side, then divide by 2.22=16+2w{\displaystyle 22=16+2w}6=2w{\displaystyle 6=2w}62=2w2{\displaystyle {
rac {6}{2}}={
rac {2w}{2}}}3=w{\displaystyle 3=w} Don't forget to include the unit of measurement. For example, for a rectangle with a perimeter of 22cm{\displaystyle 22cm} and a length of 8cm{\displaystyle 8cm}, the width would be 3cm{\displaystyle 3cm}.
