The statement, "If m∠X ≅ m∠Y and m∠Y ≅ m∠Z, then m∠X ≅ m∠Z" demonstrates: D. the transitive property.
What is the Transitive Property of Congruency?In geometry, the transitive property of congruency states that when two angles, sides, or triangles are congruent to a third angle, side, or triangle, then all three angles, sides, or triangles will be congruent to each other.
Illustrating the transitive property, if a = b, and b = c, therefore, a = b = c. We can then state that a = c.
Therefore, given that If m∠X ≅ m∠Y and m∠Y ≅ m∠Z, then m∠X ≅ m∠Z, we have:
Two angles, X and Z, which are both congruent to a third angle, Y.
Therefore, based on the transitive property, we can state that all three angles are congruent to each other, which leads us to conclude that:
m∠X ≅ m∠Z.
Thus, the statement given demonstrates the: D. transitive property.

If a triangle has lengths of 11tf and 24ft, check all the possible lengths for the third side
All the possible lengths for the third side lie between 13 to 35 feet.
What is a triangle Inequality Theorem?
In Euclidean geometry, the theorem is that the sum of any two sides of a triangle is greater than or equal to the third side; in symbols, a + b ≥ c. In essence, the theorem states that the shortest distance between two points is a straight line.
The Triangle Inequality theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.
So, a difference of two sides <x< sum of two sides, will give you the possible length of a triangle.
Therefore, 24 − 11 < x < 24 + 11
13 < x < 35 is the possible length of the third side of a triangle.
13 < x < 35 satisfies the triangle inequality theorem.
Hence, all the possible lengths for the third side lie between 13 to 35 feet.

Answer:
To solve this problem, we need to first perform the multiplication. In mathematics, multiplication is performed before division, so we should calculate the product of 6/7 and 1/2 before dividing it by any other number. To find the product, we simply multiply the numerators together to get 6 and the denominators together to get 14. So the product of 6/7 and 1/2 is 6/14.

The expected annual returns are 15% for investment 1 and 12% for investment 2. The standard deviation of the first investment’s return is 10%; the second investment’s return has a standard deviation of 5%. Which investment is less risky based solely on standard deviation? Which investment is less risky based on coefficient of variation? Which is a better measure given that the expected returns of the two investments are not the same?
a) Investment B is less risky based solely on the standard deviation.
b) Based on the coefficient of variation, Investment B is less risky.
c) The better measure of expected returns of the two investments is the coefficient of variation.
What is the coefficient of variation?The coefficient of variation shows how spread out or variable the standard deviation is to population mean.
It is a ratio of the standard deviation compared to the population mean.
A higher coefficient of variation shows a greater dispersion or risk.
The formula for the coefficient of variation is given as follows:
Coefficient of Variation (CV) = (Standard Deviation/Mean) × 100.
Investments A B
Expected annual returns 15% 12%
Standard deviations 10% 5%
Coefficient of variation = Standard deviation ÷ Expected annual returns x 100

In the diagram below of triangle BCD, E is the midpoint of BD and F is the midpoint of CD. If EF = 43-4x, and BC = 32-2x, what is the measure of EF?
The measure of the length EF of the triangle is; 21
How to solve similar triangles?We are given the the triangle BCD and we are told that;
E is the midpoint of BD.
F is the midpoint of CD
Now, since we have those midpoints, it means that by the concept of similar triangles, that;
DF/DC = EF/BC
Since F is the midpoint of DC, then it means that;
2DF = DC
We are given;
EF = 43 - 4x, and BC = 32 - 2x
Thus, we now have;
DF/(2DF) = (43 - 4x)/(32 - 2x)
1/2 = (43 - 4x)/(32 - 2x)
Cross multiply to get;
32 - 2x = 43 - 4x
4x - 2x = 43 - 32
2x = 11
x = 11/2
x = 5.5
Thus;
EF = 43 - 4(5.5)
EF = 43 - 22
EF = 21
Thus, we conclude that the side length EF is 21.

The solution is:
Answer:
to solve a system of linear equations by elimination, we need to eliminate one of the variables, for example, we could add the two equations together to eliminate the variable y. However, we need to make sure that the coefficients of the two equations are the same before we can add them together. We can do this by multiplying the first equation by -1.5 and the second equation by 1.5. This gives us the following system of equations:
-2.25x - 13.5y = -31.5
2.25x - 4.5y = 13.5
We can now add these two equations together to eliminate the variable y, which gives us the following equation:
0 = -18

The quadratic equation (x + 1)² / 46.667 - (y - 5)² / 56 = 1 represents the hyperbola in standard form.
How to derive the standard form of the equation of a hyperbola
In this question we find the equation of a hyperbola in general form, that is, a quadratic equation of the form A · x² + B · y² + C · x + D · y + E = 0, and we need to obtain the standard form of the hyperbola:
(x - h)² / a² - (y - k)² / b² = 1
Where:
(h, k) - Coordinates of the center.a, b - Length of the semiaxes.We can switch from general form into standard form by completing the square, an application of algebra properties:
6 · x² - 5 · y² + 12 · x + 50 · y - 149 = 0
(6 · x² + 12 · x) - (5 · y² - 50 · y) = 149
6 · (x² + 2 · x) - 5 · (y² - 10 · y) = 149
6 · (x² + 2 · x + 1) - 5 · (y² - 10 · y + 25) = 149 + 6 + 125
6 · (x + 1)² - 5 · (y - 5)² = 280
(x + 1)² / 46.667 - (y - 5)² / 56 = 1

the product of 0.8 and a number is 12represent the statement as an equation determine the solution set using the replacement set 0 8 1 7 15
Answer:
The product of 0.8 and a number is 12, so the equation representing this statement is: 0.8 * x = 12.
To solve this equation, we need to find the value of x that makes the equation true. We can do this by using the replacement set {0, 8, 1, 7, 15}.
If we substitute 0 for x in the equation, we get: 0.8 * 0 = 12. This equation is not true, so 0 is not a solution.
If we substitute 8 for x in the equation, we get: 0.8 * 8 = 12. This equation is not true, so 8 is not a solution.
If we substitute 1 for x in the equation, we get: 0.8 * 1 = 12. This equation is not true, so 1 is not a solution.
If we substitute 7 for x in the equation, we get: 0.8 * 7 = 12. This equation is not true, so 7 is not a solution.
Finally, if we substitute 15 for x in the equation, we get: 0.8 * 15 = 12. This equation is true, so 15 is a solution.

A door is 2 feet off the ground and a contractor needs to develop a wheelchair ramp to go on it. Ramps have to be in a ratio of 1:12 slope. How far away from the house would the ramp have to start. Explain
The slope of the ramp is the ratio of the y and x coordinates thus it will be 24 feet.
What is the slope?A slope is a tangent or angle at a point or a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
The situation is making a right-angle triangle as shown below.
The slope of the wheelchair = 2 feet / x

When it comes to a business net worth is simple:
assets - liabilities = net worth.
Assets are an expenditure that has utility through multiple future accounting periods. For example, a company pays its electrical bill. This expenditure covers something (electricity) that only had utility during the billing period; therefore, it is recorded as an expense.
Conversely, the company buys a machine, that it expects to use for the next five years. Since this expenditure has utility through multiple future periods, it is recorded as an asset.
Cash, savings, inventory, investments, equipment, and receivables are also assets. Basically, anything that is owned and could be liquidated for cash.
