Since slate tiles can vary slightly in size, it is important to do a dry run with your tiles so you know where to adjust the surface level and position of your tiles. Draw an "x" through the room with chalk. When the lines cross they will create a 90-degree angle on which you can check for even spacing. Use tile spacers during the dry run to ensure you have even spacing. If you do, you will want to reposition your layout, so that cut tiles of even width can be laid at either end. This will result in a symmetrical floor. Measure the tile to account for a one-eighth-inch (0.3-cm) grout space along the wall. You can cut slate tile with a diamond-blade wet saw, grinder or hacksaw with an abrasive blade. Place a line of chalk on them during your dry run, so that you can make this important change when you lay your mortar.

One-sentence summary -- Sketch a layout for the color scheme of the slate. Measure lines through the width and length of the room. Lay out your tile to figure out the best use of color. Decide if you will need to cut tile at the edges of the room. Cut tiles to fit around the edges of the room. Mark tiles that require extra thinset on the back to create an even surface.

Use a kitchen knife to score the foil just below the lip of the wine bottle, then remove the foil cap and throw it away. Hold the bottle securely with your free hand, but keep it well clear of the knife tip and blade. Sit down on a steady chair and hold the wine bottle in a secure position between your legs. The top of the bottle should be pointing downward, while the base of the bottle should be pointing up. Grasp the bottle near its bottom (which is now facing upward) with one hand to hold it steady.

If only your hot water taps have low pressure, look for a problem at your water heater. Here are the most common problems: Sediment clogging the water heater or the hot water supply line. flush the tank, then hire a plumber if that doesn't work. To prevent this happening again, replace the anode rod regularly and consider Installing a water softener. Hot water supply pipes that are too small. In most cases the pipe leading from your water heater should have at least a " (19mm) diameter. Leaks in the valves or the tank itself. Only attempt to repair these yourself if the leak is minor and you have experience with plumbing projects. Leaks are a common cause of low pressure. Conduct a quick check for damp spots beneath pipes, especially at the main supply line. Fix any leaky pipes you encounter. Small damp spots may be caused by condensation. Put down a couple paper towels and come back the next day to see if they are wet. If they are, you have a problem. A leaky toilet mechanism fails to block the flow from the tank to the bowl. Put a few drops of food coloring in the tank, and come back after an hour or two without flushing the toilet. If the food coloring has entered the bowl, your toilet needs a repair. Typically, all it needs is a new flapper or another cheap and easy fix. If you can hear your toilet running constantly, that's definitely a drain on your pressure. Learn how to fix it. If you still haven't found any leaks, it's time to check your water meter to confirm or deny their existence. Shut off all water in the house, then read the meter. There are two ways to check for leaks using the meter: If the small triangular or disk-shaped dial on the meter is spinning, water is still flowing. Assuming everything is shut off properly, you have a leak. Write down the reading, wait a couple hours without using any water, then check again. If you get a different reading, you have a leak. Look for the master shutoff valve near your water meter. If it's been knocked to a partially closed position, turn it back to fully open. This is rarely the problem, but it only takes a few minutes to test. Homes on low ground often have a PRV installed where the line enters the building. This valve, usually shaped like a bell, reduces the supply of water to a safe pressure for your building. On a typical model, you can turn the screw or knob at the top of the PRV clockwise to increase water pressure. It's best to turn this only a couple times, keeping track of the number of turns. Going too far can damage your plumbing. If adjusting the PRV doesn't make any difference, shut off the water supply and disassemble the valve. You may need to replace a part or the entire valve, or just clean the parts. Finding manufacturer instructions is recommended. Not all homes have a PRV, especially if the city water supply is low pressure or the building is on high ground. If your home has a water softener installed, try setting it to "bypass." If the pressure improves, have someone inspect your softener for issues.

Consider the number under observation. The characteristic is the part that comes before the decimal point; the mantissa is the part that comes after the decimal point. Antilog tables are arranged with respect to these parameters, so you need to separate them. As an example, say you need to find the antilog for 2.6452. The characteristic is 2, and the mantissa is 6452. Antilog tables are easily available; you may have one in the back of your mathematics textbook. Open the table and look for the row number consisting of the first two digits of the mantissa. Then find the column number equal to the third digit of the mantissa. In the example above, you would open the antilog table and find the row number beginning with .64, then the column for 5. In this case, you would find that the corresponding value is 4416. The antilog table also includes a set of columns known as "mean difference columns." Look at the same row as before (the row corresponding to the first two digits of your mantissa), but this time, find the column number equal to the fourth digit of the mantissa. In the example above, you would again use the row number beginning with .64, but find the column for 2. In this case, your value is 2. Once you have these values, the next step is to add them together. In the example above, you would add 4416 and 2 to get 4418. The decimal point always goes in a specific designated place: after the number of digits that corresponds to the characteristic plus 1. In the example above, the characteristic is 2. You would therefore add 2 and 1 to get 3, then insert the decimal point after 3 digits. The antilog of 2.6452 is therefore 441.8.
