Q: Look for the "HDMI" or "HDMI Out" label and fit the cable securely into the socket. This is the highest quality connection for audio and video and is typically found only on modern DVD players. Just like DVD players, only newer TV's have HDMI sockets. There may be multiple sockets available. Each HDMI socket will be labeled "HDMI" or "HDMI In" along with a potential input number. If there is an input number, like "HDMI 1," remember it for later. This is the setting your TV must be set at to see your movies. An HDMI connection only requires one cable that carries both audio and video signal, and it does not matter which end goes where. But if the cable is pulled too tightly, or one of the connections is loose, you may not get a good signal. There are a lot of different HDMI cords available, but unless you want pristine, perfect picture then any length and type of cord will work just fine as long as it reaches. Insert a DVD so that you can test both the picture and the audio. Sometimes labeled "input," this button allows you to switch where your TV gets the video and sound information. The input you choose on the TV should match the input you used for the cables. If there is not a label or you don't know what input to use, leave the DVD player on and test each input for 5-10 seconds to see where the video appears.
A: Plug the first end of the cable into the HDMI socket on the DVD player. Plug the second end of the cable into the HDMI socket on the TV. Make sure that both HDMI connections are secure. Power on the DVD player and TV. Switch the TV to the correct input using the "source" button on your TV or Remote.

Problem: Article: Aggregates are additives that make up most of a concrete mix. Fine aggregates are typically sand or crushed stone. This type of mix is best for pouring a very thin coat of concrete, such as when topping off or leveling out an existing slab. The aggregate in a concrete mix is listed on the label. You can also see it when you open the bag. Fine concrete looks smooth or has very small stones. Coarse concrete has gravel or larger stones as an additive. This type of concrete is stronger but less dense, so you can safely pour a large slab onto existing concrete. It is a good option if you need to fill a large area with something thick that will last a long time. Larger aggregates cannot be used to make thin coats, so make sure you get the type of concrete mix best suited for your project. Concrete can splash up as you mix and pour it, and that isn't anything you want in your eyes. Wear protective goggles or safety glasses with polycarbonate lenses at all times. Also consider wearing work gloves and long-sleeved clothing to protect your skin from concrete splatter. The scratch coat is a layer of wet concrete mixed to a liquid consistency similar to paint. You will need a big plastic mixing bucket. Combine the concrete in a ratio of about 1 part water to 7 parts concrete, then mix it with a wooden mixing stick or electric paddle mixer until it reaches a uniform liquid consistency. Use the same concrete you plan on using for the final layer. Have the area estimate available for the space you wish to cover, then follow the manufacturer's instructions for an estimate on how much to mix. Less is usually more with the scratch coat. Remember that is liquid, so it will spread out over the existing slab. Dump it all out onto the existing concrete, then begin spreading it around using a hand trowel or paver. Press down hard on the concrete to work the liquid mix into any cracks as you smooth out the scratch coat layer. The layer of wet concrete doesn't need to be thick. A layer about 18in (0.32cm) thick, about the thickness of a credit card, is enough. You can also use a rag or a gloved hand to spread the scratch coat. This can work well when priming small areas. The wet mix is there to help the new concrete bond to the old concrete, so you don't need a lot of it.
Summary: Purchase concrete with a fine aggregate for small repairs. Choose a coarse aggregate concrete when pouring thicker slabs. Wear eye goggles to protect yourself while mixing concrete. Mix up a scratch coat consisting of concrete and water. Spread the liquid mix over the existing concrete.

Q: The key to understanding this formula is to recognize the underlying pattern. The sum of any set of consecutive odd numbers starting with 1 is always equal to the square of the number of digits that were added together. Sum of first odd number = 1 Sum of first two odd numbers = 1 + 3 = 4 (= 2 x 2). Sum of first three odd numbers = 1 + 3 + 5 = 9 (= 3 x 3). Sum of first four odd numbers = 1 + 3 + 5 + 7 = 16 (= 4 x 4). By solving this problem, you learned more than the sum of the numbers. You also learned how many consecutive digits were added together: 41! This is because the number of digits added together is always equal to the square root of the sum. Sum of first odd number = 1. The square root of 1 is 1, and only one digit was added. Sum of first two odd numbers = 1 + 3 = 4. The square root of 4 is 2, and two digits were added. Sum of first three odd numbers = 1 + 3 + 5 = 9. The square root of 9 is 3, and three digits were added. Sum of first four odd numbers = 1 + 3 + 5 + 7 = 16. The square root of 16 is 4, and four digits were added. Once you understand the formula and how it works, you can write it down in a format that will be applicable no matter what numbers you are dealing with. The formula to find the sum of the first n odd numbers is n x n or n squared. For example, if you plugged 41 in for n, you would have 41 x 41, or 1681, which is equal to the sum of the first 41 odd numbers. If you don't know how many numbers you are dealing with, the formula to determine the sum between 1 and n is (1/2(n + 1))2
