The dimensions of the dollhouse bed are 3.6 inches × 6 inches. By dividing 10 by each dimension, the dollhouse bed's dimensions may be found.

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

The dimension of real bad;

a = 36 inches

L = 60 inches

Down scale factor = 1/10

The dimensions of the dollhouse bed are obtained by dividing 10 in each dimension;

a'=36/10

a'=3.6 inches

L'=60/10

L'=6 inches

Hence the dimensions of the dollhouse bed are 3.6 inches × 6 inches.

Answer:

f = 19.0

Step-by-step explanation:

By applying sine rule in the triangle given in the figure,

By applying triangle sum theorem,

m∠F + m∠G + m∠H = 180°

110° + m∠G + 40° = 180°

m∠G + 150° = 180°

m∠G = 30°

[tex]\frac{sin(\angle F)}{GH}= \frac{sin(\angle G)}{HF}=\frac{sin(\angle H)}{FG}[/tex]

[tex]\frac{sin(\angle 110^0)}{f}= \frac{sin(\angle 30^0)}{g}=\frac{sin(\angle 40^0)}{13}[/tex]

The length of the guy wire is approximately 74.7 feet, and the height of the antenna is approximately 72.2 feet.

Here, we have,

To find the length of the guy wire and the height of the antenna, we can use trigonometry and the concept of right triangles.

In this scenario, the guy wire represents the hypotenuse of a right triangle, and the height of the antenna represents one of the legs of the triangle.

The angle of elevation formed by the guy wire is given as 79 degrees.

Let's denote the length of the guy wire as h and the height of the antenna as a.

Using the trigonometric function sine (sin), we can relate the angle of elevation and the sides of the triangle:

sin(angle) = opposite/hypotenuse.

In this case, the opposite side is the height of the antenna (a), and the hypotenuse is the length of the guy wire (h).

sin(79°) = a/h.

To solve for h, we can rearrange the equation as:

h = a / sin(79°).

We also have another relationship between the sides of the triangle.

The base of the right triangle is given as 15 feet, and the height of the antenna is a.

Therefore, using the Pythagorean theorem, we have:

h² = a² + 15².

Now we can substitute the expression for h from the first equation into the second equation:

(a / sin(79°))² = a² + 15².

Expanding and simplifying, we get:

a² / sin²(79°) = a² + 225.

Multiplying both sides of the equation by sin²(79°), we have:

a² = sin²(79°) * (a² + 225).

Expanding again, we get:

a² = sin²(79°) * a² + 225 * sin²(79°).

Rearranging the equation, we have:

a² - sin²(79°) * a² = 225 * sin²(79°).

Factoring out a², we get:

(1 - sin²(79°)) * a² = 225 * sin²(79°).

Using the trigonometric identity sin²(θ) + cos²(θ) = 1,

we know that cos²(θ) = 1 - sin²(θ).

Therefore:

cos²(79°) * a² = 225 * sin²(79°).

Taking the square root of both sides, we have:

cos(79°) * a = 15 * sin(79°).

Simplifying, we get:

a = (15 * sin(79°)) / cos(79°).

Using a calculator or software, we find:

a ≈ 72.2 feet (rounded to one decimal place).

Now, to find the length of the guy wire (h), we can substitute the value of a into the first equation:

h = a / sin(79°).

Using a calculator or software, we find:

h ≈ 74.7 feet (rounded to one decimal place).

Therefore, the length of the guy wire is approximately 74.7 feet, and the height of the antenna is approximately 72.2 feet.

(155.301 ; 159.299)

Step-by-step explanation:

Xbar = 157.3

Sample size, n = 234

Population standard deviation, σ = 15.6

The confidence interval :

Xbar ± standard Error

Standard Error = Zcritical * σ/√n

Zcritical at 95% = 1.96

Standard Error = 1.96 * (15.6/√234) = 1.999

Lower boundary : 157.3 - 1.999 = 155.301

Upper boundary : 157.3 + 1.999 = 159.299

We all know there are 7 days in a week. How many weeks are in 259 days?

37 weeks

[tex]\frac{1}{7} :\frac{y}{259}[/tex]

y · 7 = 1 · 259

7y = 259

7y ÷ 7 = 259 ÷ 7

y = 37

Everyone is given the same number of colored pencils in art class. If there are 249 colored pencils and 8 students, how many pencils does each student receive?

31 color pencils each and 1 extra pencil

249 ÷ 8 =

31.125 colored pencils each

This rounds to 31 color pencils and 1 extra pencil.

Mr. Hughes has 155 meters of volleyball netting. How many nets can he make if each court requires 9 meters of netting?

7 courts and he will be left with 2 meters of netting

155 ÷ 9

17 and 2/9 volleyball courts

17 courts and he is left with 2 meters of netting.

Answer:

D. 96 inches.

Step-by-step explanation:

Radius of cylinder = 1/2 * 24 = 12 inches.

Radius of the cone = 1/2 * 12 = 6 inches.

Volume of the cylinder = pi r^2 h and volume of the cone = 1/3 pi r^2 h

So pi 12^2 * 8 = 1/3 pi * 6^2 * h

1152 pi = 12 pi h

h = 1152/12

h = 96 inches.
