Step-by-step explanation:

12/4

The top number always goes inside (larger or not), and the bottom number always goes on the outside (larger or not).

______

4 | 12

Ask yourself how many 4's are in 12.

Let's see one 4 is just 4.

We can probably do more 4's than that.

Two 4's gives us 4+4=8.

Let's see if we can put one 4 in there.

Three 4's gives us 4+4+4=12.

So we can fit three 4's into 12 and there is nothing left over.

______

4 | 12

-12 (since 4 times 3 or 4+4+4 is 12)

The lateral area of a cone is 400 pi cm squared. The radius is 10 cm. Find the slant height to the nearest tenth.

Ilia_Sergeevich [38]

Answer:

Option A. $40\ cm$

Step-by-step explanation:

we know that

The lateral area of a cone is equal to

$LA=\pi rl$

we have

$LA=400\pi \ cm^{2}$

$r=10\ cm$

substitute and solve for l (slant height)

$400\pi=\pi (10)l$

simplify

$400=(10)l$

$l=400/10=40\ cm$

The two rectangular prisms are similar. What is the volume of the larger rectangular prism? 240 cm³ 540 cm³ 1620 cm³ 3240 cm³ A

Andreas93 [3]

Volume of a figure is measure of the space it occupies. The volume of the larger rectangular prism is given as: Option C: 1620 cm³

<h3>How to calculate volume of a rectangular prism?</h3>

If a rectangular prism has dimensions <u>a</u> unit, <u>b</u> unit, and <u>c</u> units, then its volume is given as

$V = a \times b \times c \: \rm unit^3$

<h3>What are similar figures?</h3>

They are scaled. It means, if two figures are similar, then we can get one figure from another by multiplying some constant value(same for one pair of similar figure) to its dimensions.

For example,

if for given case, one rectangular prism has got dimensions a, b, and c centimetres, then

the second rectangular prism, which is similar, let the scale factor is 'd',t then second prism's dimensions will be a x d units, b x d units, and c x d units.

For first prism(smaller), its one side is given to be 5 cm, let its other two sides be 'b' cm, and 'c' cm, then,

$60 \: \rm cm^3 = 5\times b\times c \\\\b\times c = \dfrac{60}{5} = 12$

Now, the larger prism has 15 cm corresponding side, thus, scale factor was 3 (since 15 is 3 times 5).

Thus, its dimensions would be 15, 3 x b, 3 x c

Thus, its volume would be

$15 \times 3 \times b \times 3 \times c = 135 \times b\times c = 135 \times 12 = 1620 \: \rm cm^3$

Thus,

The volume of the larger rectangular prism is given as: Option C: 1620 cm³

9. Given a scale factor of 3, find the coordinates for the dilation of a triangle with vertices at

11Alexandr11 [23.1K]

The coordinates for the dilation of a triangle is (3 12), (12.15), and (6.0).

If the coordinate (x, y) is dilated by a scale factor of k, the resulting coordinate will be at (kx, ky)

Given the coordinate of the triangle (1 4). (4.5), and (2.0), if this coordinate is dilated by a factor of 3, the resulting coordinates will be at (3 12), (12.15), and (6.0).

Hence the coordinates for the dilation of a triangle is (3 12), (12.15), and (6.0).
