Answer:

The inequality for this would be n ≥ 20.

We know this because it must be larger than 40. We also know it can possibly be equal because the statement says "at least".

If an original conditional statement is represented by p → q, which represents the contrapositive?
Maksim231197 [3]

<span>A conditional statement has two parts, the hypothesis and the conclusion. In p and q notation, the hypothesis is always the p and the q is the conclusion. In a contrapositive statement, the statement would go, “if not q, then not p”. Therefore, the answer to this item is the second choice.  </span>

Answer:

see explanation

Step-by-step explanation:

25

The diagonals of a kite are perpendicular to each other, hence

∠EHF = 90°

The sum of the 3 angles in a triangle = 180°

In ΔEHF

∠1 + ∠2 + 90 = 180, that is

42 + ∠2 + 90 = 180

132 + ∠2 = 180 ( subtract 132 from both sides )

∠2 = 48°

26

DE and DG are congruent sides, hence

4x - 2 = 22.5 ( add 2 to both sides )

4x = 24.5 ( divide both sides by 4 )

x = 6.125

27

∠A and ∠C are congruent, hence

∠A = ∠C = 82°

The sum of the interior angles of a kite = 360°, hence

x = 360 - (82 + 82 + 140) = 360 - 304 = 56

A rectangular prism with a volume of 444 cubic units is filled with cubes with side lengths of \dfrac13
IrinaK [193]

Answer:

108 cubes

Step-by-step explanation:

Lengths of one of the cube s=\dfrac{1}{3}

Volume of a Cube  =s^3

Volume of one of the Cubes =(\dfrac{1}{3})^3=\dfrac{1}{27}

The volume of the rectangular prism is 4 cubic units.

Therefore, to find the number of cubes it takes to fill the prism, we divide the volume of the prism by the volume of the cube.

\text{Volume of Prism/Volume of Cube}=4 \div \dfrac{1}{27}\\=4 X 27 \\=108

It takes 108 cubes to fill the rectangular prism.
