The distance between the Eiffel tower and the location where the observer is standing is 2869.2929 meters.
Therefore, you are 2869.2929 meters away from the Eiffel tower.
The Eiffel Tower is 300m tall. If a person is standing at a certain location in Paris, the tower subtends an angle of 6 degrees. To calculate the distance from the Eiffel tower, trigonometry is used. Here's how you can calculate the distance between the Eiffel tower and the location you are standing in Paris;
Let AB be the height of the Eiffel Tower, which is 300 m.
Let AC be the distance between the observer and the base of the Eiffel Tower.
Let the angle of elevation at A be θ = 6 degrees.
Now, from the diagram, it is clear that;
Tan θ = AB/AC
Therefore, AC = AB/Tan θ
Substituting values, we get:
AC = 300/Tan 6 degrees
AC = 300/0.104528
AC = 2869.2929 meters.

Calculate the volume of a pie
that has flat sides so that it is
shaped like a cylinder. The pie
has a radius of 3 inches and a
height of 2 inches.
Answer:
56.54 inches
Step-by-step explanation:
If the radius is 3 inches, to find the area of the circle your equation would be A = (pi) x r^2
Your equation would look like this:
A = (pi) x 3^2
A = 28.27
Now to get the volume of the pie, you would multiply 28.27 x 2 which gives you an answer of 56.54 inches.

A man left on a trip of 450 kilometres at 10 am. He stopped for a rest for
40 minutes and had another break of an hour for lunch. What time did he
finish the trip, if he was travelling at an average speed of 50 kilometres per

Therefore, the man finished his trip at 8:40 pm with total travelling time of 10 2/3 hours.
What is fraction?In mathematics, a fraction is a representation of a part of a whole or a ratio between two quantities. It consists of two numbers, a numerator and a denominator, separated by a horizontal line, also called a fraction bar or a vinculum. The numerator represents the number of equal parts being considered, while the denominator represents the total number of parts that make up the whole.
Here,
We can solve this problem using the formula:
distance = rate x time
Let's start by finding the time it took for the man to travel 450 kilometers at an average speed of 50 kilometers per hour:
time = distance / rate
time = 450 km / 50 km/h
time = 9 hours
So the man spent 9 hours travelling. However, he also took two breaks: a 40-minute rest and a 1-hour lunch break. We need to convert these times to hours to include them in our calculation.
40 minutes is equal to 40/60 = 2/3 hours, and 1 hour is simply 1 hour. So the total time the man spent travelling, including the breaks, is:
total time = 9 hours + 2/3 hours + 1 hour
total time = 10 2/3 hours
To find the finishing time, we add the total time to the starting time of 10 am:
finishing time = 10 am + 10 2/3 hours
finishing time = 8:40 pm (rounded to the nearest minute)

Triangle XYZ will be translated to X'Y'Z' and the coordinates of Z' are (6,7).
Describe transformation.A transformation known as a translation involves shifting each point in an image uniformly in one direction. It is also a type of transformation where every point in a figure is moved by the same amount in the same direction, producing a new figure that is identical to the original.
From the graph,
The coordinates of X are (7, 11)
The coordinates of Y are (10, 14)
The coordinates of Z are (8, 7)
When triangle XYZ is translated to X'Y'Z', the X-coordinate is given as (5, 11), which means the X-coordinate shifts left 2 points, so we need to subtract 2 from X-coordinate and keep Y-coordinate as it is.
Therefore the coordinate of the triangle X'Y'Z' are as follows,
The coordinates of X' are (7-2, 11) = (5,11)
The coordinates of Y' are (10-2, 14) = (8, 14)
The coordinates of Z' are (8-2, 7) = (6, 7)

if a random variable follows a normal distribution, what is the probability that the random variable is 1.96 standard deviations below the mean? select answer from the options below 97.50% 95.00% 96.25% 98.75%
The total probability is 2.5% + 2.5% = 5.0%, which is equivalent to 0.05 or 95.00% in decimal form.
If a random variable follows a normal distribution, the probability that the random variable is 1.96 standard deviations below the mean is 95.00%.Step-by-step explanation:
Z-value for 1.96 standard deviations below the mean can be calculated as follows:
Z=(x-μ)/σ=(-1.96)
Where x is the value of the random variable, μ is the mean, and σ is the standard deviation.To find the probability, we can use a standard normal distribution table.
The table gives the probability of a standard normal random variable Z being less than or equal to a given value, denoted by P(Z ≤ z).
The Z-value we calculated is -1.96, so we look up the corresponding probability in the table:
P(Z ≤ -1.96) = 0.025.
The probability that the random variable is 1.96 standard deviations below the mean is therefore:
P(Z ≤ -1.96) = 0.025 = 2.5%
However, since we are interested in the probability that the random variable is exactly 1.96 standard deviations below the mean, we need to use a two-tailed test.
The probability of being below the mean by 1.96 standard deviations is 2.5%, and the probability of being above the mean by 1.96 standard deviations is also 2.5%.

Find the surface area of the triangular prism. A drawing of a triangular prism. The base is a right triangle with base 9 inches, height 12 inches, and third side 15 inches. The height of the prism is 29 inches
The surface area of the triangular prism is 891 square inches, calculated by finding the area of each face (two triangular and three rectangular) and adding them up.
To find the surface area of the triangular prism, we need to find the area of each face and add them up.
The triangular prism has two identical triangular faces and three rectangular faces. The triangular faces have base 9 inches, height 12 inches, and hypotenuse 15 inches. The area of each triangular face can be found using the formula for the area of a triangle:
Formula for area of each triangular face = (1/2) x base x height
= (1/2) x 9 x 12
= 54 square inches
The prism also has three rectangular faces, each with length equal to the base of the triangle (9 inches) and width equal to the height of the prism (29 inches). The area of each rectangular face can be found using the formula for the area of a rectangle:
Area of each rectangular face = length x width
= 9 x 29
= 261 square inches
Hence, the triangular prism's total surface area is:
Total surface area = 2(Area of each triangular face) + 3(Area of each rectangular face)
= 2(54) + 3(261)
= 108 + 783
= 891 square inches
Therefore, the surface area of the triangular prism is 891 square inches.

Each individual sample or dataset is described by its frequency distribution. It's the number of times in the dataset that each possible value for a particular variable appears.The probability of occurrence of a value determines how frequently it appears in a sample. Probability is a value between 0 and 1 that indicates the likelihood that something will happen:Zero denotes impossibility.1 denotes a certainty.Total people = 10 (1 - 10)

It will take 2.2 hours for the two trains to meet.
We can find the time taken by the two trains to meet by using the formula,
large Time=Distance/Speed
Let's consider the time taken by the two trains to meet be "t".The distance between two trains = 418 miles.
Now, the first train is traveling at a speed of 85 mph and the second train is traveling at a speed of 105 mph.
Let's calculate the distance covered by both the trains in time "t".The distance covered by the first train in time "t"=85t.
The distance covered by the second train in time "t"=105t.
So, the total distance covered by both the trains in time "t" is,
Distance covered = 85t+105t=190t.
But we know the distance between the two trains is 418 miles.
Therefore,190t = 418
Now, solve for "t"t = 418/190t = 2.2 hours
