article: Abrasive scrubbers made of steel wool or brushes with metal bristles will scratch your brass hinges. Instead, always clean your brass hinges with a clean, soft towel or dish cloth. A thin layer of oil can prevent brass from tarnishing. Dab a clean cloth with a bit of linseed, olive, lemon, or mineral oil. Wipe the brass hinge lightly but thoroughly with the oil of your choice. Touching the brass hinges can leave behind fingerprints, and the oils in your hands will hasten tarnishing. To keep your brass hinges looking new, adopt a "hands-off" policy.

Write an article based on this "Set up the formula for relative error. Plug in the value for the relative error. Plug in the value for the actual value. Multiply each side of the equation by the actual value. Add the actual value to each side of the equation. Subtract the actual value from the measured value."
article: The formula is x=x0xx{\displaystyle \delta x={
rac {x_{0}-x}{x}}}, where x{\displaystyle \delta x} equals the relative error (the ratio of the absolute error to the actual value), x0{\displaystyle x_{0}} equals the measured value, and x{\displaystyle x} equals the actual value. This will likely be a decimal. Make sure you substitute it for x{\displaystyle \delta x}. For example, if you know that the relative error is .025, your formula will look like this: .025=x0xx{\displaystyle .025={
rac {x_{0}-x}{x}}}. This information should be given to you. Make sure you substitute this value for x{\displaystyle x}. For example, if you know that the actual value is 360 ft, your formula will look like this: .025=x0360360{\displaystyle .025={
rac {x_{0}-360}{360}}}. This will cancel out the fraction. For example:.025=x0360360{\displaystyle .025={
rac {x_{0}-360}{360}}}.025360=x0360360360{\displaystyle .025 imes 360={
rac {x_{0}-360}{360}} imes 360}9=x0360{\displaystyle 9=x_{0}-360} This will give you the value of x0{\displaystyle x_{0}}, giving you the measured value. For example:9=x0360{\displaystyle 9=x_{0}-360}9+360=x0360+360{\displaystyle 9+360=x_{0}-360+360}369=x0{\displaystyle 369=x_{0}} Since absolute error is always positive, take the absolute value of this difference, ignoring any negative signs. This will give you the absolute error. For example, if the measured value is 369 ft, and the actual value is 360 feet, you would subtract 369360=9{\displaystyle 369-360=9}. So, the absolute error is 9 feet.

Write an article based on this "Use a blender. Choose your flavor of whey protein. Mix in fruits or other ingredients. Add ice cubes. Add flavor-enhancing ingredients."
article:
Combining the ingredients in a blender is the most convenient way to make a shake. Follow the instructions on the whey protein container to measure out the proper amount of whey protein powder and blend with the recommended portion of liquid and any other ingredients until smooth. If you do not have a blender, you can use an electric mixer, blender bottle, or use a whisk or fork to mix the ingredients in a glass or bowl. You can buy whey protein in a variety of flavors, which will affect the taste of your smoothie. Flavors include vanilla, strawberry, blueberry, banana, chocolate, and more. Whey protein shakes can be made with fruits and other ingredients to change the flavor and nutritional content. Many recipes can be found in books and online for various preparations of whey protein shakes. To make it easier to blend or mix fruits into whey protein shakes, add liquids first. Depending on your preference, add between one to two cups of one or more of the following: Fruit juice Banana Peaches Pears Mango Watery fruits, including oranges, pineapple and watermelon Milk, soy milk, almond milk, coconut milk or other low-fat milks Blended ice cubes will thicken and cool your whey protein shake, giving it the consistency of a smoothie or shake. Alternatively, you can freeze bananas, raspberries and other fruits (or buy them frozen) and add them to the drink. You can even make ice cubes out of milk and use these instead. Whey protein shakes may benefit from the addition of ingredients that improve the flavor. Add these ingredients to your liking and you will improve your shake's flavor. Some ingredients to consider adding include: Honey Vanilla, nutmeg, cinnamon Yogurt Dried fruit, including raisins, apricots and dates Chocolate, vanilla, strawberry or other milkshake powders
