The answer is B
you have to find the cubic roots of 27 and 729 to find the side lengths of the cubes. The first one has a side length is 3, and the second one has a side length of 9 which s 3x larger.
pls make me brainliest ! ;-)

Answer:

Step-by-step explanation:

Ratio of sides = a : b , then

Ratio of volumes = a³ : b³

Here the ratio of volumes = 27 : 729, hence

Ratio of sides = $\sqrt[3]{27}$ : $\sqrt[3]{729}$ = 3 : 9

Ratio of sides = 3 : 9 = 1 : 3 ← in simplest form

Hence sides of larger cube are 3 times sides of smaller cube → B

9. What is the vertex of the function? f(x) = 3x² - 8x + 10

Delvig [45]

Answer:

The vertex of the function is (1.333, 4.667)

Step-by-step explanation:

1. Calculate -b / 2a. This is the x-coordinate of the vertex.

2. simply plug -b / 2a into the equation for x and solve for y.

$Y = 3x^{2} - 8x + 10\\Compare with the form of y = ax^{2} + bx + c\\So that means a = 3, b = -8, and c = 10.$

Calculate -b/2a:

$X = -(-8)/2(3)$

$X = 8/6$

This is equal to 1.33 recurring

Plug 8/6 for x and solve for y:

$Y = 3x^{2} - 8x + 10$

$Y = 3(\frac{8}{6})^{2} - 8(\frac{8}{6}) + 10$

$Y = \frac{48}{9} - \frac{64}{6} + 10\\$

This is equal to 4.66 reccuring.

In a football tournament, the Bees scored 9 less than three times as many points as the Hornets. The Wasps scored 28 more points

gladu [14]

B = bees, w = wasps, x = hornets

b + w + x = 184
b = 3x - 9
w = x + 28

(3x - 9) + (x + 28) + x = 184...combine like terms
5x + 19 = 184
5x = 184 - 19
5x = 165
x = 165/5
x = 33 <== points scored by Hornets
