Answer:

Step-by-step explanation:

What you can do is figure it out each side at a time then put the information together:

In a 6 by 9 RECTANGLE, a 3 by 3 SQUARE, can go in twice horizontally, and three times vertically, so 2 x 3 = 6

Since the side facing us is 3 as well, it goes into 18 six times or 6 x 6 = 36

The volume of a sphere is 28/3 times it surface area, find the surface area

pentagon [3]

Answer:

615.44 units squared

Step-by-step explanation:

Let the volume and surface area of the sphere be V and S respectively.

$\therefore V = \frac{28}{3} \times S\\\\\therefore \frac{4}{3} \pi {r}^{3} = \frac{28}{3} \pi {r}^{2} \\ \\ \frac{ {r}^{3} }{ {r}^{2} } = \frac{28\pi}{3} \times \frac{3}{4\pi} \\ \\ r = 7 \: units \\ \\ \because S = 4\pi {r}^{2} \\ \\ \therefore \: S = 4 \times 3.14 \times {7}^{2} \\ \\ \therefore \: S = 12.56 \times 49 \\ \\ \therefore \: S =615.44 \: {units}^{2}$

If y varies inversely as x2 and y=6 when x=30, what is y when x=6

ladessa [460]

Answer:

y = 150

Step-by-step explanation:

y varies inversely as x²

yx² = k

----------------

y = 6 when x = 30

6(30²) = k

6(900) = 5400

--------------------------

what is y when x = 6

y(6²) = 5400

y(36) = 5400

y = 5400/36

y = 150

What is the area of this figure?

Ugo [173]

Answer:

11610

Step-by-step explanation:

First you do the top rectangle which the area for that is 144 which is 4 times 4 times 3 times 3.

Then you do the middle rectangle which the area is 441 which is 7 times 7 times 3 times 3.

Then you do the last rectangle which the area is 11025 which is 15 times 15 times 7 times 7.

Then lastly you add all three areas which is 144+441+11025=11610. So therefore, the answer is 11610.

The image of a figure is shown. What are the coordinates of X in the pre-image of the figure if the rule that created the image

nydimaria [60]

The coordinates of X in the pre-image of the figure is (3.2, 0.6) if the transformation rule is T_(-5.2, 1.4)(x, y)

<h3>What is geometric transformation?</h3>

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

As we can see in the figure.

The transformation rule is T_(-5.2, 1.4)(x, y)

X'(-2, 2)

Before the transformation:

X = (-2+5.2, 2-1.4)

X = (3.2, 0.6)

Thus, the coordinates of X in the pre-image of the figure is (3.2, 0.6) if the transformation rule is T_(-5.2, 1.4)(x, y)
