A cylinder with a diameter of 24 inches and a height of 8 inches has the same volume as a cone with a diameter of 12 inches.
What is the height of the cone?
A. 4 Inches
B. 16 inches
C. 48 inches
D. 96 Inches
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.

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°

Answer:
x =14
<A = 7x -11 = 87
<B = 2x-3 = 25
<C = 5x -2 = 68
Step-by-step explanation:
The sum of the angles add to 180
7x -11 + 2x-3 + 5x-2 = 180
Combine like terms
7x +2x+5x -11-3-2 =180
14x-16=180
Add 16 to each side
14x-16+16 =180+16
14x = 196
Divide each side by 14
14x/14 =196/14
x =14
<A = 7x -11 = 7*14 -11 = 98-11 = 87
<B = 2x-3 = 2*14 -3 = 28-3 = 25
<C = 5x -2 = 5*14 -2 = 70-2 = 68

Kathy is building a bed for her dollhouse. She used her real bed as a guide for how to create the dollhouse bed. Her bed is 36 inches wide and 60 inches long. If she wants to scale this down by 1/10, what would be the dimensions of the dollhouse bed? Explain how you got your answer.
*Use the term SCALE FACTOR in your explanation.
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.
What exactly is dilation?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.

A guy wire connects the top of an antenna to a point on level ground at 15ft from the base of the antenna. The angle of elevation formed by this wire is 79. What is the length of the wire and the height of the antenna?
Answer:
VEFG4KLKB
Step-by-step explanation:
BLB
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.

A study of women’s weights found that a randomly selected sample of 234 women had a mean weight of 157.3 lb. Assuming that the population standard deviation is 15.6 lb., construct a 95% confidence interval estimate of the mean weight of all women.
Answer:
(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
