Liula [17]

Answer:

<h2>              y = 4</h2>

Step-by-step explanation:

x + 2y = 10    ⇒  2y - 10 = -x

-x + 4y = 14

2y - 10 + 4y = 14

6y = 24

 y = 4

The aspect ratio (the ratio of screen width to
Strike441 [17]

Answer:

Width = 36in

Size = 42.02

Step-by-step explanation:

Given

x \to width

y \to height

x : y = 16 : 9

Required

The size of screen of height 20,6in

First, we calculate the width using the following equivalent ratios

16: 9 = x : 20.6

Express as fraction

\frac{16}{ 9} = \frac{x }{ 20.6}

Solve for x

x = 20.6 * \frac{16}{ 9}

x = 36.62

Hence:

Width = 36in --- approximated

So, we have:

x = 36.62

y =20.6

The size (diagonal) is then calculated using:

Size = \sqrt{x^2 + y^2

Size = \sqrt{36.62^2 + 20.6^2

Size = \sqrt{1765.3844

Size = 42.02

Size =42in --- approximated

Ken is 6 feet tall and is walking away from a streetlight. The streetlight has its light bulb 14 feet above the ground, and Ken
AlekseyPX
Ken's distance is:  d(t)=1.7t

Ken's shadow is:

(14-6)/d(t)=14/s

8/d(t)=14/s

s=14d(t)/8

s=1.75d(t) and using the value for d(t) we have:

s=1.75(1.7t)

s=2.975t  and if you want it in terms of d, d=1.7t, t=d/1.7 so

s=2.975(d/1.7)

s=1.75d

In the triangle below, 4/5 represents which ratio?
ASHA 777 [7]
<span><u><em>Answer:</em></u>
sin (C)

<u><em>Explanation:</em></u>
<u>In a right-angled triangle, special trig functions can be applied. These functions are as follows:</u>
sin (theta) = </span>\frac{opposite}{hypotenuse}
<span>
cos (theta) = </span>\frac{adjacent}{hypotenuse}
<span>
tan (theta) = </span>\frac{opposite}{adjacent}<span>

<u>Now, let's check the triangle we have:</u>
<u>We have two options:</u>
<u>First option:</u>
5 is the hypotenuse of the triangle
4 is the side adjacent to angle B
Therefore, we can apply the <u>cos function</u>:
cos (B) = </span>\frac{4}{5}<span>

<u>Second option:</u>
5 is the hypotenuse of the triangle
4 is the side opposite to angle C
Therefore, we can apply the <u>sin function</u>:
sin (C) = </span>\frac{4}{5}
<span>
Among the two options, the second one is the one found in the choices. Therefore, it will be the correct one.

Hope this helps :)
