Solvent-based epoxies adhere well and are available in many colors. The drawback is that these products are extremely hazardous. Water-based products are clear in color, but these products do not give off hazardous fumes.  Both products typically contain from 40-60% solids (epoxy). The higher the percentage, the harder your floor will be, and the more expensive the product. You absolutely must use a ventilator to apply solvent-based epoxy products. Epoxy primers can smooth out minor imperfections in the floor and give the epoxy a better base to bond to. It is important to use primer on floors that are very porous, flaky, chalky, or rough. Primers can also add strength and durability to any floor. Always select a product that is compatible with the epoxy you plan to use. For a 450 square feet (42 m2) garage (a typical 2-car garage), you will need 2–3 gallons (7.6–11 L) of epoxy per coat. This can vary based on the percent of solids in the epoxy you buy, so check the labels. Purchase enough epoxy to cover your floor in at least 2 coats.  Solvent-based epoxy products can be harder to find. Some paint specialty stores may carry them, but you may need to visit an industrial-supply store. Water-based epoxy products can be purchased at most home supply stores. Gloves, eye protection, lung protection, and good rubber boots can help keep you safe while applying epoxy. Turn off gas/power to any water heaters or other appliances in the garage. Take precautions to keep children and pets away from the area during application and drying. Always use a ventilator to apply solvent-based epoxy products.

That being said, first open a terminal by pressing Ctrl+Alt+T. Type in sudo apt-get update && sudo apt-get upgrade -y, you might get prompted for a password, type it in and press ↵ Enter, no dots or asterisks will appear as you type, this is normal. While technically optional, this step is always recommended before installing anything, keeping your system updated will help prevent many problems. Type in sudo add-apt-repository ppa:webupd8team/java, and then press ↵ Enter. Type in sudo apt-get update and wait for the lists to be refreshed. Type in sudo apt-get install oracle-java9-installer -y. You might get prompted for a password, type it in and press ↵ Enter, no dots or asterisks will appear, this is normal. In many Ubuntu derivatives, OpenJDK is set to be the default Java to be used, if you want Oracle's Java to be used by default you need to type sudo apt install oracle-java9-set-default.

Though a bow tie can be tied with the collar either up or down, you’ll have a much easier time seeing what you’re doing with the collar up, so lift it and ensure the top button of your shirt is buttoned. Bow ties are one size fits all, but they have ways to adjust the length either with a slider or button holes. Most bow ties will also have pre-marked neck measurements informing you how to size them based on your neck measurement. Move the slider or buttons based on your neck measurement.

In its simplest form, the DCF formula is DCF=CFn(1+r)n{\displaystyle {\text{DCF}}={\frac {CF_{n}}{(1+r)^{n}}}}. In the formula, CFn{\displaystyle CF_{n}} refers to the future value of the cash flow for year n and r represents the discount rate. For example, using the first year of the example investment from the part "Gathering Your Variables," the present value of that cash flow for $1,000 after one year, using the discount rate of 9 percent, would be represented as: DCF=$1,000(1+0.09)1{\displaystyle {\text{DCF}}={\frac {\$1,000}{(1+0.09)^{1}}}}. The discount rate must be represent as a decimal rather than by a percentage. This is done by dividing the discount rate by 100. Therefore, the 9 percent rate from above is shown as 0.09 (9÷100{\displaystyle 9\div 100}) in the equation. The total value of discounted cash flows for an investment is calculated as the present values of each cash flow. So, the other cash flows must be added to the calculation in the same method as the first one. For the previous example, we would add the $2,000 and $3,000 payments at the end of the second and third years to the equation. In total, this gives: DCF=$1,000(1+0.09)1+$2,000(1+0.09)2+$3,000(1+0.09)3{\displaystyle {\text{DCF}}={\frac {\$1,000}{(1+0.09)^{1}}}+{\frac {\$2,000}{(1+0.09)^{2}}}+{\frac {\$3,000}{(1+0.09)^{3}}}} Solve your equation to get your total discounted value. The result will be the present value of your future cash flows. Start by adding the discounted rate to the 1 within parentheses:  This gives DCF=$1,000(1.09)1+$2,000(1.09)2+$3,000(1.09)3{\displaystyle {\text{DCF}}={\frac {\$1,000}{(1.09)^{1}}}+{\frac {\$2,000}{(1.09)^{2}}}+{\frac {\$3,000}{(1.09)^{3}}}}  From there, calculate the exponent. This is done by raising the "1.09" in parentheses to the power above it (1,2, or 3). Solve this by either typing "[lower value]^[exponent]" into Google or using the exponent button, xy{\displaystyle x^{y}} on a calculator. After solving the exponent, the equation will be: DCF=$1,0001.09+$2,0001.1881+$3,0001.295029{\displaystyle {\text{DCF}}={\frac {\$1,000}{1.09}}+{\frac {\$2,000}{1.1881}}+{\frac {\$3,000}{1.295029}}}  Next, divide each cash flow by the number underneath it. This yields: DCF=$917.43+$1,683.36+$2,316.55{\displaystyle {\text{DCF}}=\$917.43+\$1,683.36+\$2,316.55}  Finally, add up the present values to get the total, which is DCF=$4,917.34{\displaystyle {\text{DCF}}=\$4,917.34}. In some cases it may be necessary to change the discount rate used to account for changes to expectations, risk, or taxes. For example, businesses analyzing a project might add a risk premium on to the discount rate used to discount the cash flows from a risky project. This artificially lowers the returns to account for risk. The same might be done for a very long time window between the present and the future cash flows to account for uncertainty.  Discount rates may be converted to real rates (rather than nominal rates) by removing inflation from the discount rate. A spreadsheet program, such as Excel, has functions that can help with these calculations.
