The vertices of about isosceles trapezoid are located at (2,5),(6,5),(9,3) and?
Answers
To determine the fourth vertex of an isosceles trapezoid given three vertices, we use symmetry and properties of isosceles trapezoids, concluding the missing vertex is likely at (-1,3).
Explanation:To find the fourth vertex of an isosceles trapezoid given three vertices, we need to use the properties of isosceles trapezoids. The properties pertinent to solving this problem include parallel bases and non-parallel sides of equal length. Given vertices at (2,5), (6,5), and (9,3), we know the top base is parallel to the x-axis, as the y-coordinate is the same (5) for the first two points.
For the trapezoid to be isosceles, the fourth vertex must follow the pattern of equal non-parallel sides. Observing the pattern of the given points, and noting that the length of the non-parallel side from (9,3) should equal that of the side starting from (2,5), we conclude the missing point must maintain this equality in distance and form a right angle, mirroring the shape on the opposite side.
Without specific lengths, we apply symmetry principles. The height difference between the known base and the third vertex (3) indicates a 2-unit drop, suggesting the opposite side will mirror this. Thus, the fourth vertex should be 2 units below the other base vertex, at (2,5), making the y-coordinate 3. Given the distances in x are equal (4 units from each end vertex to their respective base vertex), the fourth vertex is at (-1,3).

In one U.S city, the taxi cost is $2 plus $0.60 per mile. If you are traveling from the airport, there is an additional charge of $5.50 for tolls. How far can you travel from the airport by taxi for $43.50?
Answers
Answer:
60 miles
Step-by-step explanation:
Let
x ----> the number of miles
we know that
The number of miles multiplied by $0.60 per mile plus $2 plus the charge of $5.50 for tolls (because you are travelling from the airport) must be equal to $43.50
so
The linear equation that represent this problem is
[tex]0.60x+2+5.50=43.50[/tex]
Solve for x
Combine like terms left side
[tex]0.60x+7.50=43.50[/tex]
subtract 7.50 both sides
[tex]0.60x=43.50-7.50[/tex]
[tex]0.60x=36[/tex]
divide by 0.60 both sides
[tex]x=60\ miles[/tex]

A ski run has an angle of elevation of 24.4 degrees and a vertical drop of 1100 feet . To the nearest foot how long is the ski run
Answers
Answer:1100 feet
Step-by-step explanation: the drop is 11 feet
To find the length of the ski run, we use tangent of the angle of elevation (24.4 degrees) which equals the vertical drop (1100 feet) divided by the length of the run. Calculating this gives a length of approximately 2433 feet for the ski run.
Explanation:To calculate the length of the ski run with an angle of elevation of 24.4 degrees and a vertical drop (rise) of 1100 feet, we use trigonometry, specifically the tangent function.
Tangent of an angle in a right triangle equals the opposite side (rise) divided by the adjacent side (run). In this case, we have:
tan(24.4 degrees) = rise / run
Plugging in the known value for the rise (1100 feet), we get:
tan(24.4 degrees) = 1100 / run
This allows us to solve for the run (length of the ski run):
run = 1100 / tan(24.4 degrees)
Using a calculator, we find that:
run ≈ 1100 / 0.4525
run ≈ 2432.96 feet
This can be rounded to the nearest foot to give a ski run length of approximately 2433 feet.

Step-by-step explanation:
We are given;
The equation 2x + 4y = 7
A point (2, -5/4)
We are supposed to determine the equation of a line perpendicular to the given line;
First, we determine the slope of the given line by writing the equation in the form of y= mx + c
2x + 4y = 7
y = -1/2x + 7/4
m₁ = -1/2
But, for perpendicular; m₁×m₂= -1
Therefore;
-1/2 × m₂ = -1
m₂ = 2
Thus, we can get the equation of the line;
Taking another point (x, y)

George is twice as old as Edward, and Edward’s age exceeds Robert’s age by 4 years. If the sum of the three ages is at least 56 years, what is Robert’s minimum age?
Answers
To find Robert's minimum age, we need to determine the ages of George and Edward first. Let's assume Edward's age is x. According to the information given, George is twice as old as Edward, so George's age is 2x. Edward's age exceeds Robert's age by 4 years, meaning Robert's age is x - 4. The sum of the three ages is at least 56 years, so we can write the equation x + 2x + (x - 4) >= 56.
Explanation:To find Robert's minimum age, we need to determine the ages of George and Edward first.
Let's assume Edward's age is x. According to the information given, George is twice as old as Edward, so George's age is 2x.
Edward's age exceeds Robert's age by 4 years, meaning Robert's age is x - 4.
The sum of the three ages is at least 56 years, so we can write the equation x + 2x + (x - 4) >= 56. Simplifying this, we get 4x - 4 >= 56. Adding 4 to both sides, we have 4x >= 60. Dividing by 4, we find that x >= 15.
Therefore, Edward's minimum age is 15 years, and Robert's minimum age is 15 - 4 = 11 years.

b.) Find the range.
c.) Find the variance and standard deviation.
Answers
Without the specific lengths of the rivers, it's not possible to calculate the precise mean, median, range, variance, and standard deviation. In general, these values provide insights into the distribution and variability of river lengths on the South Island of New Zealand.
Explanation:Unfortunately, the specific lengths of the rivers mentioned in the question were not provided, so it's not possible to calculate the mean, median, range, variance, and standard deviation without that data. In general, to calculate these statistical terms:
Mean is calculated by adding up all the lengths of the rivers and dividing by the number of rivers.Median is the middle value when the river lengths are arranged in ascending order. If there is an even number of rivers, it's the average of the middle two values.Range is found by subtracting the shortest river length from the longest.Variance is the average of the squared differences from the Mean.Standard deviation is the square root of the variance, indicating how much the river lengths vary from the average length.These calculations are essential for understanding the distribution and variability of river lengths on the South Island of New Zealand.

rent the ballroom. Which value for h makes the inequality true?
A. 2 b.3 c . 5 d . 7
Answers
Answer:
The value of h that makes the inequality true is 2.
Step-by-step explanation:
Ms. Jenson needs to rent a ballroom for an event and she must spend less than $625 for the rental fee. The cost to rent the ballroom is $350 for 3 hours. The cost for every extra hour is $125.
She wrote the inequality,
625 > 350 + 125h
to find h, the number of extra hours she can rent the ballroom.
Solving this inequality we get
125h < 275
⇒ h < 2.2
So the value of h that makes the inequality true is 2. (Answer)
The required value of h < 2 or the number of extra hours she can rent the ballroom.
Given that,
She must spend less than $625 for the rental fee,
The cost to rent the ballroom is $350 for 3 hours,
The cost for each additional hour is $125,
She wrote the inequality, 625 > 350 + 125h.
We have to find,
The value of h, the number of extra hours she can rent the ballroom. Which value for h makes the inequality true.

Step-by-step explanation:
13 - 4= 9 left 6 and half would be three
To find out how many laps Bryan ran, an equation was formulated combining the laps Amanda and Clifford ran with the total laps, which, when solved, showed Bryan ran 6 laps.
Explanation:To solve the problem, let's denote the number of laps Bryan ran as B, Amanda ran 4 laps, and Clifford ran half as many laps as Bryan, so that's B/2 laps.
According to the problem, together they ran a total of 13 laps.
Now we can write an equation based on the information given:
4 + (B/2) + B = 13
Next, we solve for BD:
Combine like terms:
B + B/2 = 13 - 4
1.5B = 9
Divide by 1.5 to solve for B:
B = 9 / 1.5
B = 6
So, Bryan ran 6 laps.
