What are non-perfect square numbers?
Non-perfect square numbers are numbers that are not formed from the square of a number. 12, 13, 14, 21, 99, etc, are all non-perfect square numbers because when you square root them you do not get a whole number, which means they are not formed by any whole number, x, being squared (x^2).
What is the probability that a randomly selected two-digit positive integer is a perfect square or a perfect cube?
There are 90 two-digit numbers from 10 to 99. Of those, 6 are perfect squares (16, 25, 36, 49, 64, and 81) and 2 are perfect cubes (27 and 64). Each perfect square or root has a probability of 1 in 90 in being drawn.
What is 11 feet x 9 feet in square meters?
Answer: 99 ft² = 9.19740 m²
What is 9ft x 11ft in square meters?
9.2m2You could change feet to meters then multiply to get square meters, or you could multiply to get square feet, then convert to square meters.Many people know that there are 2.54cm in an inch. 12 inches in a foot makes 2.54x12=30.48cm or 0.3048 meters in a foot. 1 square foot = 0.3048x0.3048 = 0.0929 square meters. (I could have just told you that, but it's not my style.)9ft x 11ft = 99 sq ft = 99 x 0.0929 = 9.197... = about 9.2 square meters.
What is the area of a rectangle with length 11cm and width of 9cm?
To find the area (A) of any rectangle, we multiply the length (l) by the width (w). In the case of a rectangle that is 11 cm by 9 cm, we do this:Arectangle = l x w = 11 cm x 9 cm = 99 cm2or 99 square centimeters.
