The yearbook club had a meeting. The meeting had 6 people, which is two-thirds of the club. How many people are in the club?

timofeeve [1]

The answer would be 9 because if you add one more 3rd to the number 6 that would be 3 so 3 * 3 = 9 there are 9 people in the book club

Afina-wow [57]

Answer:

≈ 18 cm

Step-by-step explanation:

1. Find the length of half a circle of radius 3.5 cm:

$\tt \cfrac{C}{2}= \cfrac{2\pi r}{2}=\pi r=3.14\cdot3.5=10.99 \ cm$

2. Find the length of the diameter:

D = 2r = 2 · 3.5 = 7 cm

3. Find the perimeter of the figure:

P = 10.99 + 7 = 17.99 ≈ 18 cm

Answer:

(3x + 2)(9x^2 - 6x + 4)

Step-by-step explanation:

Simple Question.

27x^3 + 8 = (3x)^3 + (2)^3

You can now apply the sum of the cubes formula:

x^3 + y^3 = (x + y)(x^2 - xy + y^2),

(3x)^3 + (2)^3 = (3x + 2)(3^2x^2 - 2*3x + 2^2)

= (3x + 2)(9x^2 - 6x + 4)

Solution: (3x + 2)(9x^2 - 6x + 4)
