Shawn is buying a new plasma television. The height of the screen of the tv is one half the width plus 5 inches. the width is 30 inches. What is the height of the tv?

The constant of proportionality for the considered equation is 29.4

Firstly, there is proportional relationship.

Two values [tex]x[/tex] and [tex]y[/tex] are said to be in a proportional relationship if [tex]x=ky[/tex], where [tex]x[/tex] and [tex]y[/tex] are variables and [tex]k[/tex] is a constant.

The constant k is called constant of proportionality.

The proportional relationship between x and y can be written symbolically as

[tex]x \propto y[/tex]

That middle sign is called sign of proportionality.

For the given case, we've got the equation as:

[tex]m = 29.4h[/tex]

Here, m and h are variables.

Thus, using the aforesaid definition, in this equation, the constant of proportionality is  29.4

or the answer 45.

I can't under stand sir!

Step-by-step explanation:

We need to find the demand so the variable x is unknown.

We know that the variable p is 37.55 so we replace that in the equation

[tex]37.55 = 40 - \sqrt{0.01x + 1} [/tex]

Subtract Property

[tex] - 2.45 = - \sqrt{0.01x + 1} [/tex]

Division Property

[tex]2.45 = \sqrt{0.01x + 1} [/tex]

[tex](2.45) {}^{2} = 0.01x + 1[/tex]

[tex]6.0025 = 0.01x + 1[/tex]

[tex]5.0025 = 0.01x[/tex]

[tex]500.25 = x[/tex]

So the answer is about 500 units per day

The angle of depression formed by the cable is 44°.

The angle of depression is an angle measured downward from a horizontal line to the line of sight between an observer and a point that is below the observer. It is used to describe the angle formed between a horizontal reference line (usually the observer's line of sight) and a line drawn from the observer's eye to a point of interest that is lower in elevation.

According to the question the tower, cable, and path makes a triangle whose

base = 350 feet,

hypotenuse = 500 feet.

Since, cos[tex]\theta[/tex] = [tex]\frac{base}{hypotenuse}[/tex]

                  = [tex]\frac{350}{500}[/tex]

                  = [tex]\frac{7}{10}[/tex]

[tex]\theta[/tex] = arccos([tex]\frac{7}{10}[/tex])

 = 0.77539749 radians

 = 0.77539749 × [tex]\frac{180^o}{\pi}[/tex]

 = 0.77539749 × [tex]\frac{180^o}{3.14}[/tex]

 = 44.45°

 ≈ 44°.

Thus, the correct answer is C. 44°.

Answer:

x = 1

Step-by-step explanation:

a^2 + b^2 = c^2

The hypotenuse (c) and a side length is already given, so:

x^2 + 12 = 13

x^2 = 1

Square root of 1 = 1

So, x = 1

You can check it by 1+12=13

Answer:

3821.9 [cm³].

Step-by-step explanation:

1) the required volume can be calculated as:

V=V(prism)-V(cylinder);

2) V(prism)=32*12*11=4224 [cm³];

3) V(cylinder)=π*r²*32=3.1415*4*32≈402.1 [cm³];

4) finally, V=4224-402.1=3821.9 [cm³].

For more info see the picture in the attachment.

Answer:

3,822.08 cm2

Step-by-step explanation:

You would start off by finding the volume of the who post which is 4,224. You then would find the volume of the hole cut out which is 401.92. Then you would subtract 401.92 from 4,224 giving you 3,822.08.

Answer:

KL ≈ 3.6

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan24° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{KL}{KM}[/tex] = [tex]\frac{KL}{8}[/tex] ( multiply both sides by 8 )

8 × tan24° = KL , then

KL ≈ 3.6 ( to the nearest tenth )

Answer:

3.6

Step-by-step explanation:

Using Trigonometry we know;

SOH, CAH, TOA

Therefore we will use TOA as we want to find the opposite which will be

tan=opposite/adjacent

so, opposite=tan(x) times adjacent (rearranged the formula)  

which then will be:

tan(24) × 8= 3.561829482
