What is the perimeter of this chicken?


Chicken???
11 is a prime number so the only number it is divisible by is 1 or itself. So if it was a piece of material it would measure 11 feet by 1 foot so the perimeter is the sum of the four sides (11+11+1+1) which equals 24 feet.
If it was circular the perimeter would be a little over 23.

Tip

Removing a recessed downlighter


To remove a small recessed downright from a paperboard ceiling first isolate the power supply
then gently prise the fitting slightly away from the ceiling about 1cm and measure the size of the hole in the paperboard. (It's probably about 7cm)
Get a piece of hardboard or plywood about 15cm x 15cm (6"x6") . Cut a U shaped slot the same width as the hole (7cm in my case) to make shield to fit around the cylindrical part of the light and protect the plasterboard
Now, holding the shield in place with your thumbs, pull the light further out with your fingertips until you can see the springs that are holding it in position .
Use long nosed pliers to compress the coiled part of a spring you should then be able to prise it off the lugs on the light fitting. Do the same with the other spring and the fitting will be released.

What is the area of the triangle if its sides are 8cm., 17cm.&15cm.


Hello

OK, the formula for the Area of a triangle is A=0.5xBasexHight. For this formula to be applicable you will need to have a 90 degree angle in this triangle.

For example:

lock123_5.jpg
Base = 8
Hight = 15

A = 0.5x8x15


Let me know if you need any further assistance.

Kind regards
Andrea

Menu display intermitent


display is disclosed which produces multiple visual displays in an intermittent manner which includes a display housing having a perimeter wall which is transparent during visual display and is an opaque mirror between visual displays. The perimeter wall of the display housing is a composite structure which preferably includes a transparent cylindrical substrate which is coated with an optical film and an opaque mask which defines display windows. Multiple visual displays are produced by a rotating display base which carries rows of rotating display elements. Preferably, the display elements are elongated triangular elements having three image faces which bear images which create the visual displays. The triangular display elements are arranged in a triangular configuration wherein the rows intersect one another at acute angles and are carried by the rotating base. The rotating base includes three display positions and each of the triangular elements includes three display positions. A stationary observer would see nine different visual displays and may see themselves mirrored in between and during the changes of visual displays. The perimeter wall of the display housing becomes transparent as the triangular display elements are backlit along their entire length by elongated fluorescent or neon light tubes. When the light tubes are off, the cylindrical display housing is an opaque mirror, preferably, about its entire periphery and height. Other embodiments of the invention include a single row of triangular display elements, and a rotating display base which includes display faces consisting of only a single display element.
