Step-by-step explanation:

Given;

Length of library on drawing = 13 inches

Actual length of library = 78 feet

In order to find the scale we divide the actual length by the length of library on drawing.

So, scale = 1 inch = 6 feet

Keywords: Scale, Maps

Answer:

C

Step-by-step explanation:

78 feet/13 inches=6 inches/foot

Answer:

x = √289

x = 17

Answer:

I think it's answer choice A!

Step-by-step explanation:

The reason why I think that it is A is because of the given y values. The x values are consistent through all of the given choices, but if graphed, there is a distance of three units between the y-value of 4 and the y-value of 7. I personally like to use Desmos when it comes to trying to get a visual graph of coordinates. I hope this at least helped a little!

The distance between (2,4) and (2,7) is 3 therefore, these two points have a distance of 3 units, therefore, option (A) will be correct.

Let's consider we have two points (x₁, y₁) and (x₂, y₂) the distance between these two points is given by the formula;

[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]

The distance between with two points (x₁, y₁) and (x₂, y₂) is given as,

[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]

In option (A),

Points are (2,4) and (2,7).

The distance between them will be,

[tex]d = \sqrt {\left( {2 - 2 } \right)^2 + \left( {4 - 7 } \right)^2 }[/tex]

d = √(3²) = 3

Hence "The distance between (2,4) and (2,7) is 3 therefore, these two points have a distance of 3 units".

Answer:

7°

Step-by-step explanation:

Just a quick clarification, swap A and B on the diagram.

If CAD is a right angle, it is equal to 90°. Since AB is bisecting CAD, angles CAB and DAB are congruent(equal) and complementary(add up to 90) angles, and thus equal 45°. By the transitive property, if DAB = (7x - 4)° and also equals 45°, (7x - 4)° = 45°. So we can simply solve for x.

7x - 4 = 45
7x - 4 + 4 = 45 + 4
7x = 49
7x/7 = 49/7
x = 7

Answer:

The correct answer is:

6 inches by 6 inches

Step-by-step explanation:

Given that

Area of Enlarged photo = 256 square inches

Let x be the side of original photo

then the equation for area of new enlarged photo will be:

[tex](x+10)^2 = 256[/tex]

We have to solve the given equation to find the side length of original photo

Taking square root on both sides

[tex]\sqrt{(x+10)^2} = \sqrt{256}\\x+10 = 16[/tex]

Subtracting 10 from both sides

[tex]x+10-10 = 16-10\\x = 6[/tex]

So the side length of original photo is 6 inches. The dimensions will be 6 inches by 6 inches.

Hence,

The correct answer is:

6 inches by 6 inches

Answer:

  5.69 cm

Step-by-step explanation:

The mnemonic SOH CAH TOA can remind you of the relationships between angles and sides in a right triangle. Here, the useful ones are ...

  Cos = Adjacent/Hypotenuse

  Sin = Opposite/Hypotenuse

__

Using the first of these, we can find GD:

  cos(52°) = GC/GD

  GD = GC/cos(52°)

Using the second of these, we can find GH:

  sin(64°) = GH/GD

  GH = GD·sin(64°)

Substituting for GD, we find ...

  GH = GC·sin(64°)/cos(52°)

  GH ≈ (3.9 cm)(0.8988/0.6157)

  GH ≈ 5.69 cm

_____

Additional comment

The length 2.77 cm given in your question is the approximate length of DH. That solution is DH = (3.9 cm)·cos(64°)/cos(52°) ≈ 2.7769 cm ≈ 2.78 cm.

Problems of this nature tend to be formulated different ways, so the specific answer will depend on the specific question. Angles and lengths and requested information may vary, even though the picture looks very similar. Read all the words.

Answer:

So after reflecting over the x-axis, the equation is:

[tex]-y = x-2[/tex]

so the equation in the slope-intercept form

[tex]-y = x-2[/tex]

[tex]y=-x+2[/tex]

Here,

Step-by-step explanation:

Given the equation

[tex]y = x - 2[/tex]

Reflecting over the x-axis inverts the sign of the y-coordinate, but the sign of the x-coordinate remains the same.

So after reflecting over the x-axis, the equation is:

[tex]-y = x-2[/tex]

Now, writing the equation in the slope-intercept form

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept

so the equation in the slope-intercept form

[tex]-y = x-2[/tex]

[tex]y=-x+2[/tex]

Answer:

16.7

Step-by-step explanation:

We can use the Pythagorean Theorem [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex].  So we write the equation below and solve for b.

[tex]9^{2}[/tex] + [tex]b^{2}[/tex] = [tex]19^{2}[/tex]

81 + [tex]b^{2}[/tex] = 361

[tex]b^{2}[/tex] = 280

b = 16.7

Answer:

h²=p²+b²

(19)²-(9)²=b²

361-81= b²

b²=280

b= √280
