Two Consecutive Odd Numbers: D, D+2

(D+2) + 2D = 4D - 27
D + 2 + 2D = 4D - 27
3D + 2 = 4D - 27
3D + 29 = 4D
29 = D

Two Consecutive Odd Numbers are 29, 31

Check. . 31 + 2(29) = 4(29) - 27
..................31 + 58 = 116 - 27
.................89 = 89 ..... CORRECT!

Which of the following(s) is true of a rectangle?
arsen [322]
<h2>Explanation:</h2>

Let's take a look at all of our options.

A. it is also a square

  • A rectangle is NOT <em>always </em>a square because a square has congruent sides, so that means all four of its sides are <em>always </em>equal.
  • A rectangle <em>can </em>be a square but it can also not be a square, so therefore A cannot be an option because it is not always true about a rectangle.

B. the sum of its angle measures is 360

  • This is true because every quadrilateral's angle measures will add up to 360 degrees, no matter what. This is like how a triangle's angle measures always add up to 180 degrees.
  • B is an option because it is an ALWAYS true statement.

C. it has four congruent angles

  • A rectangle always has 90 degree angles, giving it its shape.
  • Since a rectangle always has the same-degree angles, that means that it DOES have four congruent angles.
  • C is also an option because it is always true.

D. it has four congruent sides

  • A rectangle does not ALWAYS have four congruent sides. Say for example a rectangle has a longer length than its width.
  • A square has four congruent sides, but a rectangle is not always a square, therefore this option is not applicable for a rectangle since it is not always true.
<h2>Answers:</h2>

B and C are always true of a rectangle.

Of the 800 participants in a marathon, 120 are running to raise money for a cause. How many participants out of 100 are running
artcher [175]

Answer:

15 % are running for a cause.

Step-by-step explanation:

120 out of 800 are running for a cause.

So out of 100,  120 / 8

= 15 are running for a cause.

15 out of a 100 = 15%.
