Q: Your electric blanket features a control cord that provides power through a wall plug. Whenever you want to clean the blanket, remove this cord from the blanket. Before removal, turn off the blanket and unplug it.  The control cord should never be submerged in water.   Before cleaning the blanket, check to make sure that all of the wire heating elements within the blanket are positioned as they should be, and that none of them have worn through the blanket’s fabric. If the wire heating element has worn through the fabric in any location, or the connection point between the blanket and the control cord is damaged in any way, discontinue use of the blanket. If you have an older electric blanket with a control cord that is not detachable, do not wash it in a washing machine. Instead, carefully hand wash the blanket, taking care not to submerge the control cord. Your electric blanket will come with a user’s manual that includes specific washing instructions.  These instructions may be included on a “product care” label attached to your blanket, a booklet in the blanket’s packaging, or on the packaging itself. Almost always, you’ll be directed to pre-soak the blanket, wash it briefly on a gentle cycle, and rinse.  A brief spin cycle will also likely be recommended. Most manufacturers recommendations will direct you to soak the blanket for anywhere from five to fifteen minutes. In addition to the specific amount of time, they will also recommend different temperatures of water, ranging from cold to warm. If a specific temperature is not mentioned regarding temperature or duration of pre-soak, go with a cold water soak for fifteen minutes. Almost all modern electric blankets can be washed in your washing machine. Most manufacturers do not recommend a full wash cycle, however. In fact, most blankets only need a few minutes’ wash on your machine’s “delicate” or “gentle” cycle.  Use only a small amount of a mild washing detergent. Do not use any other cleaning chemicals. In particular, never bleach your electric blanket. Rinsing cycles can be even shorter. Just one minute of rinsing with cool or lukewarm water is the standard recommendation. Meanwhile, most blankets do benefit from a single standard spin cycle. Though it may surprise you, modern electric blankets are intended to be washed in a washing machine. If you have an old blanket that is not damaged in any way, however, you may want to wash it by hand. For instance, if your blanket’s power cord is not removable, it needs to be carefully washed by hand.  The key is agitating the heating elements within the blanket as little as possible. To wash by hand, dunk the blanket (not including any electrical cords) into a tub with cold water and mild detergent and swish it around for a minute or two. Let it soak for fifteen minutes, squeeze soapy water out, and rinse in cool water before drying.
A: Disconnect the power cord before cleaning. Check the manufacturer’s recommendations. Pre-soak the blanket. Wash briefly and gently. Rinse and spin briefly. Take care when hand washing.

Q: Calling Nickelodeon directly isn't a matter of using one single telephone number — the network has regional offices all over the world, each with its own number. However, Nickelodeon's corporate headquarters are in New York City, so the number for this office is suitable for a wide variety of global questions and concerns. If you're calling from outside the United States, don't forget to add your country's exit code before dialing the phone number. For instance, people in Australia should dial "0011" before proceeding "1-212..." As noted above, Nickelodeon has a number of smaller regional offices besides its New York headquarters. These may be more suitable for local questions and concerns than the New York headquarters, so you may want to use these numbers instead, especially if you live near one of these offices. Three of Nickelodeon's most important regional offices' numbers are listed below:  Florida: 1-407-363-8500 California: 1-818-736-3000 London: 1-732-779-8353 If you're a journalist or a member of the press, rather than calling Nickelodeon's offices, use the company's press and PR contacts. These professionals' jobs are to help ensure that your question or concern is answered as quickly as possible, so they're usually a much better choice for fact-checking questions, company information, and so on than any single office. As noted above, Nickelodeon has too many press contacts to list here. For a complete list of phone numbers, use the same Press page as referenced above for online press inquiries.
A: Use 1-212-846-2543 for the corporate offices in New York. Use regional offices' numbers for local concerns. Use press contacts' numbers for press inquiries.

Q: Once you’ve recorded the measurement for the top diameter, place the tape measure at one end of the bottom edge of the lamp shade. Pull it across to the opposite side to get the proper measurement. Write down the second measurement with the top diameter to make sure you know the precise size of the shade. Mark this measurement as “bottom diameter.” Set the shade down on the table once more. Place the end of the measuring tape at the top edge of the shade, and pull it down to the bottom edge to measure the slope.  Sometimes, a shade’s slope is referred to as its height. If you have a square lamp shade, it obviously won’t have slope. Measure from top to bottom in the same manner, though, to get the height of the shade. Record the next measurement with the top and bottom diameters. Mark it as the shade’s “slope” or “side.” Once you’ve recorded all 3 measurements for the shade, you can choose the proper size for a new shade. Most shades list the measurements in the following order: top diameter, bottom diameter, and slope/height.
A: Hold the measuring tape across the bottom diameter. Record the number. Measure the shade’s sloping side. Jot down the number. Use the measurements as a guide for a replacement shade.

Q: Two triangles can be proved similar by the angle-angle theorem which states: if two triangles have two congruent angles, then those triangles are similar. This theorem is also called the angle-angle-angle (AAA) theorem because if two angles of the triangle are congruent, the third angle must also be congruent. This is because the angles of a triangle must sum to 180°. Using a protractor, measure the degree of at least two angles on the first triangle. Label the angles on the triangle to keep track of them.  Choose any two angles on the triangle to measure. Example: Triangle ABC has two angles that measure 30° and 70°. Again, use a protractor to measure two of the angles on the second triangle. If both angles are identical on both triangles, then the triangles are similar to each other.  Remember, if two angles of a triangle are equal, then all three are equal. Example: The second triangle, DEF, also has two angles that measure 30° and 70°. Once you have identified the congruent angles, you can use this theorem to prove that the triangles are similar. State that the measures of the angles between the two triangles are identical and cite the angle-angle theorem as proof of their similarity.  It is possible for a triangle with three identical angles to also be congruent, but they would also have to have identical side lengths. Example: Because both triangles have two identical angles, they are similar. Note: If the two triangles did not have identical angles, they would not be similar. For example: Triangle ABC has angles that measure 30° and 70° and triangle DEF has angles that measure 35° and 70°. Because 30° does not equal 35°, the triangles are not similar.
A:
Define the angle-angle (AA) theorem. Identify the measure of at least two angles in one of the triangles. Measure at least two of the angles on the second triangle. Use the angle-angle theorem for similarity.
