Option C:

The name of the figure is rhombus, because it has four sides of equal length and opposite sides that are parallel.

Solution:

In the given figure, all sides are equal and they are parallel to opposite side.

To find which name is suitable for the figure.

<u>Trapezoid:</u>

Trapezoid have two non-parallel sides and two parallel sides.
Four sides of trapezoid are not equal in length.

Therefore option A and option B are not true.

<u>Rhombus:</u>

Rhombus have four equal sides and opposite sides are parallel.
But all angles are not right angles.

Therefore Option D is not true.

Option C is the correct answer.

The name of the figure is rhombus, because it has four sides of equal length and opposite sides that are parallel.

This monitor has a diagonal length of 19 inches and an aspect ratio of 5:4. What are the width and height of the monitor? Round

nasty-shy [4]

<em>Rounded to the nearest tenth of an inch the Witdth of the monitor is 14.8 inches while the Height of the monitor is 11.9 inches.</em>

<h2>Explanation:</h2><h2 />

The aspect ratio is defined as:

<em>"The proportional relationship between the width and height of an image"</em>

It is usually expressed in a mathematical language as:

$x:y \\ \\ x: \ Width \\ \\ y: \ Height$

So, it is true that:

$x:y=5:4 \\ \\ or: \\ \\ \frac{x}{y}=\frac{5}{4} \\ \\ \therefore x=\frac{5y}{4}$

In this case, we know that the monitor has a diagonal length (D):

$D=19in$

So, by Pythagorean theorem:

$D^2=361 \\ \\ 361=x^2+y^2 \\ \\ Since \ x=\frac{5y}{4}$

$D^2=361 \\ \\ 361=x^2+y^2 \\ \\ Since \ x=\frac{5y}{4} \\ \\ 361=\left(\frac{5y}{4}\right)^2+y^2 \\ \\ 361=\frac{25y^2}{16}+y^2 \\ \\ \frac{41}{16}y^2=361 \\ \\ y^2=\frac{261\times 16}{41} \\ \\ y=\sqrt{140.87} \\ \\ y=11.869in$

Finding x:

$x=\frac{5(11.869)}{4} \\ \\ x=14.836in$

<em>Finally, rounded to the nearest tenth of an inch the Witdth of the monitor is 14.8 inches while the Height of the monitor is 11.9 inches.</em>

Can some one please help me

saw5 [17]

Basically, all you have to do is substitue the terms given at the top.

x = -3

y = 6

z = -4

<em>The first one will be set up like this:</em>

(-3) + 6 + (-1) = 2

<em>The second one will be set up like this: </em>

-15 + (- -3) + 6 = -6

<em>The third one will be set up like this:</em>

3(-3) - 2(6) + (-4) = -25

<em>The fourth one will be set up like this:</em>

2(-4) - 3 (6) + 4(-3) = -38

<em>The fifth one will be set up like this: </em>

3 ( -3) + 2 (6) + (-4) = -1

<em>The sixth will be set up like this: </em>

(-3)(-4)

---------- = -1

-2 (6)

<em>The seventh will be set up like this:</em>

2 (6) (-4) - 3 (-3) = -39

Hope this helps! Have a good day/night! c:

What is 2 to the power of 4/3 equal to

Reika [66]

Answer:

<h2><u>E</u><u>k</u>sponent</h2>

$\sf{ \large{ \boxed{ \red{ {a}^{ \frac{n}{m} } = \sqrt[m]{ {a}^{n} } } } }}$

$\sf{ {2}^{ \frac{4}{3} } }$

$= \sqrt[3]{ {2}^{4} }$

$= \sqrt[3]{2 \times 2 \times 2 \times 2}$

$= \boxed {\bold{\sqrt[3]{16}(c.) }}$

What is the value of -6+3-3(-18) ?<br> (Need ASAP with steps!)

oee [108]

-6+3-3(-18)

Okay.

Work from left to right.
-6 plus 3 equals -3.
(Think of it as in a number line, from the spot of -6, move right three units. This will give you -3. Anyways..)

Now you have -3-3
The result is -6.

-6(-18)
Negative six times negative eighteen equals positive 108.

The answer is 108.
(Sorry for the long reply)

Pls answer i’ll give brainliest

oee [108]

Answer:

PQR and JK

Step-by-step explanation:

ΔGHJ ≈ ΔPQR by the Transitive Property of Congruence. GH ≈ JK since corresponding parts of congruent figures are congruent.

Pls mark as brainliest. I would really appreciate it if you did.
