IK and LN are parallel lines. Which angles are vertical angles?

Answer:

42.

Hope that helps. x

Step-by-step explanation:

(Easy way)

If one side is 12 and the other is 9, we need to do 12 + 12 and 9 + 9 which equals to 42.

(Long way)

With a trapezoid we can get an image of one rectangle and s right-angle triangle next to it. So now we have found out the perimeter of the rectangle and so we're moving on to the triangle. The base is 6 and the height is obviously going to be 12. So what we do is, 12 + 12 = 24 and 6 + 6 = 12 = 36. Since we worked out the perimeter of two rectangles we have to half the number that we got for the triangle rectangle. So half of 36 is 18, and now we add up all the numbers we are left with. 24 + 18 = 42.

Answer:

Write the problem as a mathematical expression.

b(12)=4.8b

Move 12 to the left of b.

12b=4.8b

Move all terms containing b to the left side of the equation.

7.2b=0

Divide each term by 7.2 and simplify.

Answer:

The initial value of the boat was $20,000

The percent decrease per year of the value of the boat is 10%.

The interval on which the value of the boat is decreasing while Harry has it is (0,10)

Step-by-step explanation:

It is given that the boat costs $20,000 in 2010 when x = 0. So, the initial value of the boat was $20,000.

Next, find the percent decrease per year of the value of the boat. Consider the general form of an exponential equation, y = a(b)x, where a is the initial value of the boat, b is the base of the exponent, x is the number of years after 2010, and y is the value of the boat, in dollars.

Consider the point (1 , 18,000) which lies on the graph of this situation. Substitute x = 1, y = 18,000, and a = 20,000 into the exponential equation and isolate b.

Recall that for exponential decay, b = 1 - r where r represents the decay rate. Substitute b = 0.9 into this equation and solve for r.

So, the decay rate is 0.1, and the percent decrease per year of the value of the boat is 10%.

Harry bought the boat in 2010, and plans on selling it after 10 years in 2020. Therefore, the interval on which the value of the boat is decreasing while Harry has it is [0, 10].

acres = square feet / 43,560

A square foot (sq ft) and an acre are both units of measurement for area. An acre is a unit commonly used to measure land area, particularly in the United States and the United Kingdom, while a square foot is a smaller unit of measurement used for smaller areas.

To convert square feet to acres, we can use the conversion factor of 1 acre = 43,560 square feet. This means that for every 1 acre, there are 43,560 square feet.

To find out how many acres are in a certain number of square feet, we can use the formula:

acres = square feet / 43,560

For example, if we want to know how many acres are in 12,000 square feet, we can plug in the numbers and get:

acres = 12,000 / 43,560 = 0.276 acres

So, 12,000 square feet is equal to 0.276 acres.

Similarly, if you want to know how many square feet are in a certain number of acres, you can use the formula:

square feet = acres x 43,560

For example, if we want to know how many square feet are in 2 acres, we can plug in the numbers and get:

square feet = 2 x 43,560 = 87,120 square feet

So, 2 acres is equal to 87,120 square feet.

It is important to note that, measurements may vary depending on country and context. However, generally 1 acre equals to 43,560 sq ft is considered as a standard. And it can be used multiple times in converting square feet to acres or vise versa.

Notice that here we are working with a parabola with a vertical axis of symmetry, so the -coordinate of the focus is the same as the -coordinate of the vertex.

Step-by-step explanation:

Let's denote the side length of the square base as x, and the height of the box as h.The volume of the box is given as 2000 in³, so we have the equation:

V = x²h = 2000

To minimize the total cost of material, we need to minimize the surface area of the box. The surface area consists of the top, bottom, and four sides of the box.

The cost of the top and bottom material is 30 pesos per square inch, and the cost of the side material is 15 pesos per square inch. So the total cost, C, can be expressed as:

C = 2(30x²) + 4(15xh)

Now we can express h in terms of x from the volume equation:

h = 2000 / x²

Substituting this into the cost equation, we get:

C = 2(30x²) + 4(15x(2000 / x²))

C = 60x² + 12000 / x

To minimize the cost, we can differentiate the cost function with respect to x and set it equal to zero:

dC/dx = 120x - 12000 / x² = 0

Simplifying this equation, we get:

120x³ - 12000 = 0

Dividing both sides by 120, we have:

x³ - 100 = 0

Solving for x, we find:

x = ∛100 = 10

Substituting this value of x back into the volume equation, we can find h:

h = 2000 / x² = 2000 / 100 = 20

Therefore, the dimensions of the box that minimize the total cost of material are:

Side length of the square base: x = 10 inches

Height of the box: h = 20 inches

The atria, or top chambers of the heart, beat too fast in atrial flutter. As a result, the heart beats quickly yet typically in a regular rhythm.

An example of a heart rhythm disturbance (arrhythmia) brought on by issues with the heart's electrical circuitry is atrial flutter.

Atrial fibrillation, a frequent disease that causes the heart to pulse irregularly, is comparable to atrial flutter.

Atrial flutter patients have a cardiac rhythm that is less erratic and more controlled than atrial fibrillation patients. A person may occasionally have both atrial flutter and atrial fibrillation in the same episode.

This will give us a single value that is the best-predicted test score for a person who studies 4.5 years.

Based on the significant linear correlation between years of study and test scores, we can use regression analysis to find the best predicted test score for a person who studies 4.5 years. The regression equation can be represented as:

predicted test score = a + bx

where "a" is the y-intercept (the predicted test score when years of study is 0), "b" is the slope (the change in predicted test score for every additional year of study), and "x" is the number of years of study.

Assuming we have the necessary data and calculations for the regression equation, we can substitute x = 4.5 into the equation to find the predicted test score:

Colligative properties are dependent on the concentration of the solute, but they are not dependent on the identity of the solute.

Colligative properties are physical properties of a solution that depend on the concentration of solute particles, regardless of their chemical nature. These properties include boiling point elevation, freezing point depression, vapor pressure lowering, and osmotic pressure. The magnitude of these effects is determined by the number of solute particles present in the solution, rather than the specific type of solute.

For example, when a solute is dissolved in a solvent, it disrupts the regular arrangement of solvent molecules, making it more difficult for them to escape into the vapor phase. This leads to a higher boiling point and a lower vapor pressure compared to the pure solvent. Similarly, the presence of solute particles lowers the freezing point of the solvent, as it interferes with the formation of a crystalline lattice.

The colligative properties are proportional to the concentration of solute particles, regardless of the chemical nature of the solute. This means that if two solutions have the same concentration of solute particles, they will exhibit the same colligative property effects, even if the solutes are different compounds.

In summary, colligative properties depend on the concentration of solute particles, but not on the specific identity of the solute itself.
