Which statement is true about 1?
xeze [42]

Answer:

C. It is a whole number that is neither prime nor composite.

Step-by-step explanation:

A prime number is a number that has two factors: one and another number. Thus, since 1 only has one factor (itself), it cannot be a prime number.

However, a composite number must have more than two factors, which 1 doesn't have either.

Since 1 is a whole number (not a decimal or fraction), and it is neither prime nor composite, the answer would be C.

Have a nice day!

A floor whose length and width is 50 m and 40 m respectively needs to be covered by rectangular tiles. The dimension of each til
Gnoma [55]

Answer:

1000

Step-by-step explanation:

area of rectangle = width x length

Given:

  • width of floor = 40 m
  • length of floor = 50 m

⇒ area of floor = 40 x 50 = 2000 m²

Given:

  • width of tile = 1 m
  • length of tile = 2 m

⇒ area of tile = 1 x 2 = 2 m²

Number of tiles needed = area of floor ÷ area of one tile

                                       = 2000 ÷ 2

                                       = 1000
