Q: Is it sticky? Did the knife fall into something that is just not wiping off easily? How successful this will be depends on the type of "goop" it is. If you have no idea, it is best to start with the mildest cleaner available and progress to the strongest. Try cleaning agents in this order (rinsing and drying thoroughly in between):  Water, ammonia, light mineral oil, "tape remover" or "goop remover" products from the store. This will prevent future oxidation.
A: Observe whether the knife has some substance on the blades. Clean the "goop" off. Thoroughly oil the knife when you're finished cleaning.

Q: One of the quickest, easiest options is to copy-paste your Word document into TextFixer's converter, or upload it to Online-Convert.com. These free tools quickly create a version of the document into HTML, but some of your formatting may be lost. If you'd like more conversion options, or you don't like the results from the tools above, one of these other free online tools might have what you're looking for:   Word2CleanHTML strips most of the formatting from the document, to make an HTML document that follows best web developer practices. It also offers several options for how to make specific converting decisions, such as how to handle non-standard characters or empty paragraphs. ZamZar.com's converter allows both ordinary html5 conversion, and conversion to the deprecated html4 format, which will still work on most browsers and may be more familiar for some users. This tool requires an email address to use.  wordtohtml.net like the other online converters Word to HTML lets you paste your text and get an instant conversion. In addition to the normal features it also offers control over what content to remove (images, tables etc.). It also offers the option to use advanced find and replace commands, as well as regular expression support. This may be a good option if you are working on a Word document collaboratively, so you can share the document with collaborators, then invite them to follow this step to see the exact HTML document you're converting to:  Sign in to a Google account at Google Drive. Click the red Create button, then select Document. Copy-paste your Word document into the blank Google Drive document. Use Google Docs menu to select File → Download as → web page. If you have to convert hundreds of files to HTML, use commercial software that can convert them all at once. Here are a couple options that have free trials available:  Word Cleaner - desktop, online or component version NCH Doxillion - desktop version for Windows & OSX
A: Use a simple online tool. Use a tool with more options. Use Google Drive. Use more advanced software for large jobs.

Q: Let's say you're working with the following problem: "Becky is selling tickets to her school's talent show for 5 dollars each. The amount of money she collects is a function of how many tickets she sells. What is the range of the function?" In this case, M represents the amount of money she collects, and t represents the amount of tickets she sells. However, since each ticket will cost 5 dollars, you'll have to multiply the amount of tickets sold by 5 to find the amount of money. Therefore, the function can be written as M(t) = 5t. For example, if she sells 2 tickets, you'll have to multiply 2 by 5 to get 10, the amount of dollars she'll get. To determine the range, you must first find the domain. The domain is all of the possible values of t that work in the equation. In this case, Becky can sell 0 or more tickets - she can't sell negative tickets. Since we don't know the number of seats in her school auditorium, we can assume that she can theoretically sell an infinite number of tickets. And she can only sell whole tickets; she can't sell 1/2 of a ticket, for example. Therefore, the domain of the function is t = any non-negative integer. The range is the possible amount of money that Becky can make from her sale. You have to work with the domain to find the range. If you know that the domain is any non-negative integer and that the formula is M(t) = 5t, then you know that you can plug any non-negative integer into this function to get the output, or the range. For example, if she sells 5 tickets, then M(5) = 5 x 5, or 25 dollars. If she sells 100, then M(100) = 5 x 100, or 500 dollars. Therefore, the range of the function is any non-negative integer that is a multiple of five. That means that any non-negative integer that is a multiple of five is a possible output for the input of the function.
A: Read the problem. Write the problem as a function. Determine the domain. Determine the range.

Q: Locate your toilet's shut-off valve, usually near the back of the toilet and connected to the wall. Turn the valve handle clockwise to shut off the water so you can work on the toilet without any spills or leaks. Do not use pliers or wrenches to twist the valve handle, as this can permanently damage it. Open the top of the toilet tank so you can watch it drain as you hold down the lever. Keep the lever held down until the entire toilet tank has drained. Inspect the tank for any puddles on the bottom, and sop them up with your sponge to prevent spills as you handle your toilet. If you have a significant amount of water left in the toilet tank, use a turkey baster as an alternative. There will also be residual water left in the toilet bowl—sop it up with your sponge or turkey baster before working on the toilet. The water supply line is the tube that connects the shut-off valve to the toilet. Use a wrench to unscrew the supply line from the tank so you can move the toilet around as you level it.
A:
Close your toilet's shut-off valve. Flush your toilet and hold down the lever. Use a sponge to absorb any residual water in the tank. Disconnect the water supply line from the tank.
