Screen tip, icon, and pointer are all elements related to the graphical user interface (GUI) of a computer system. A screen tip is a small box or pop-up that appears when the user hovers the mouse pointer over an icon or object, providing additional information or instructions. Icons are small graphical representations that represent files, folders, applications, or functions. The pointer is the on-screen symbol controlled by the mouse, used to select and interact with objects on the screen. Therefore, all three options are correct as they are all components of the GUI.

A pipe is 200 feet long. How many inches long is the pipe?
=
__________________________________.
(HINT:
1 foot = 12 inches)
(1
yard = 3 feet)
Correct Answer(s)
2400
Explanation
The pipe is 200 feet long. To find the length of the pipe in inches, we need to convert feet to inches. Since 1 foot is equal to 12 inches, we can multiply 200 by 12 to get the length of the pipe in inches. Therefore, the pipe is 2400 inches long.

You'd like to pave the area around the pool. Your pool is square with
a side of 30 feet. The pool is centered in a square area with a side
of 40 feet. How many square feet (area) will you have to pave?
Correct Answer(s)
700
Explanation
The area of the square pool can be calculated by multiplying the length of one side by itself, which is 30 feet multiplied by 30 feet, resulting in 900 square feet. Since the pool is centered in a larger square area with a side of 40 feet, the total area that needs to be paved is equal to the area of the larger square minus the area of the pool. Therefore, the area to be paved is 40 feet multiplied by 40 feet (1600 square feet) minus 900 square feet, which equals 700 square feet.
