The angle measures 43 degrees and its supplementary angle measures 180 - 43 = 137 degrees.

In geometry, the supplementary angle of an angle is the angle that, when added to the given angle, results in a sum of 180 degrees. In other words, two angles are supplementary if their sum is 180 degrees.

For example, if an angle measures 60 degrees, its supplementary angle would measure 120 degrees, since 60 degrees + 120 degrees = 180 degrees.

Let x be the measure of the angle in degrees.

By definition, the supplementary angle of x measures 180 - x degrees.

We are given that the angle measures 94 degrees less than its supplementary angle, so we can write:

x = (180 - x) - 94

Simplifying and solving for x, we get:

2x = 180 - 94

2x = 86

x = 43

Therefore, the angle measures 43 degrees and its supplementary angle measures 180 - 43 = 137 degrees.

f'(x) = -36/x²,  f'(-3) = -4,  f'(0) = Undefined , f'(6) = -1/6

The average rate of change of profit as x changes from 4-6 is 17.

Using the definition of the​ derivative, find f'(x). Then find f'(-3), f'(0), and f'(6) when the derivative exists. Given f(x) = 36/x. We need to find the derivative of f(x) to solve the problem.

To find the derivative of f(x), we use the quotient rule of differentiation.

(d/dx) (u/v) = [(v × du/dx) - (u × dv/dx)] / v²

The derivative of f(x) using the quotient rule is:

(d/dx)(36/x) = [(x × d/dx (36)) - (36 × d/dx(x))]/(x²)= [-36/x²]

So, f'(x) = -36/x²

Then we can find f'(-3), f'(0), and f'(6) when the derivative exists.

We know f'(x) exists if x ≠ 0.So, f'(-3) = -36/(-3)²= -4 f'(0) = Undefined (since x = 0) f'(6) = -36/6²= -1/6

Suppose that the total profit in hundreds of dollars from selling x items is given by P(x) = 2x² - 5x + 7. We need to find the average rate of change of profit as x changes from 4-6. We know that the average rate of change of a function f(x) over the interval [a, b] is: (f(b) - f(a)) / (b - a)Here, P(x) = 2x² - 5x + 7, a = 4, and b = 6.

So, the average rate of change of profit as x changes from 4-6 is:(P(6) - P(4)) / (6 - 4)=(2(6)² - 5(6) + 7 - 2(4)² + 5(4) - 7) / (6 - 4)= (72 - 30 - 8) / 2= 17

The average rate of change of profit as x changes from 4-6 is 17.

According to given question Mike has 25 candies in the beginning.

Let's assume that Mike had "x" candies in the beginning.

After giving 15 candies to his friend, he would have had (x - 15) candies left.

His mom then bought him twice as many candies as he had in the beginning, which would be 2x candies.

So, the total number of candies Mike has now is (x - 15) + 2x = 60.

Combining like terms, we get 3x - 15 = 60.

Adding 15 to both sides, we have 3x = 75.

Finally, dividing both sides by 3, we find that x = 25.

Therefore, Mike had 25 candies in the beginning.

The ∠BAE ≅ ∠DCF by SAS congruence of triangles. The solution has been obtained by using the congruence of triangles.

What is congruence of triangles?

If all three corresponding sides and all three corresponding angles of two triangles have the same size, the triangles are said to be congruent. These triangles can be moved, flipped, twisted, and turned to achieve the same result. They are parallel to one another when moved.

We are given the following:

AB ≅ CD

AD || BC

BG ≅ HD

∠CGE ≅ ∠AHF

AE ≅ FC

Now,

EF ≅ EF as it is the common side

Since, AD || BC so,

∠BCA ≅ ∠CAD as they are alternate interior angles

From this we get that triangle BAC ≅ triangle ACD.

So, the ∠BAE ≅ ∠DCF.

Larry uses the car for the first 5 slots (75 minutes) and returns it on time to avoid any fine. He then uses his bike for the remaining 2 slots, which takes 6 slots (3 times longer than using the car).

Therefore, in total, Larry uses the car for 5 slots and the bike for 6 slots, for a total of 11 slots.

On average, Larry expects to use the bike for (6/11) of his total slots. Since each bike delivery takes 3 times longer than a car delivery, we can say that Larry expects to spend 3 times as much time on the bike as he would in the car. Therefore, the average time he expects to spend on the bike (in terms of slots) is:

False because the statement "a 95 percent confidence interval estimate will have a margin of error.

A 95% confidence interval (CI) estimate is a range of values that is likely to contain the true population mean with 95% confidence. The margin of error for a confidence interval depends on the sample size, the variability of the data, and the desired level of confidence.

The general formula for the margin of error of a 95% confidence interval for the population mean is:

Margin of error = (z-value) x (standard deviation /√n)

where z-value is the number of standard deviations corresponding to the desired level of confidence (for a 95% CI, this value is 1.96), standard deviation is the standard deviation of the sample data, and n is the sample size.

The margin of error is usually expressed as a percentage of the sample mean, not the population mean. Moreover, the percentage of the margin of error is not fixed, but it varies depending on the data and the sample size.

Therefore, the statement "a 95 percent confidence interval estimate will have a margin of error that is approximately + or - 47.5 percent of the size of the population mean" is not correct.

The art studio can offer a maximum of 8 painting classes and 5 pottery classes per week, while still meeting the time constraint and earning at least $1000 per week.

To find the maximum number of classes the art studio can offer per week, we need to set up an equation based on the time constraint.

Let's assume that the studio offers x painting classes and y pottery classes per week. Since each painting class is 1 hour long and each pottery class is 1.5 hours long, the total time spent on classes can be represented by the equation:

1x + 1.5y ≤ 40

This equation states that the total number of hours spent on painting classes (1x) plus the total number of hours spent on pottery classes (1.5y) must be less than or equal to 40 hours per week.

To find the minimum revenue the art studio can earn per week, we can set up another equation based on the cost of each class and the minimum revenue requirement.

Let's assume that each painting or pottery class costs $35. Then the total revenue earned per week can be represented by the equation:

35x + 35y ≥ 1000

This equation states that the total revenue earned from painting classes (35x) plus the total revenue earned from pottery classes (35y) must be greater than or equal to $1000 per week.

Now we have two equations:

1x + 1.5y ≤ 40

35x + 35y ≥ 1000

We can use these equations to find the maximum number of classes the art studio can offer per week.

To do this, we can graph the two equations on the same coordinate plane and find the point where they intersect.

When we do this, we get the point (x, y) = (8, 16/3).

This means that the art studio can offer a maximum of 8 painting classes and 16/3 (or approximately 5.33) pottery classes per week, while still meeting the time constraint and earning at least $1000 per week.

Note that since the studio can only offer one class at a time, they would need to round down the number of pottery classes to 5 in order to offer a whole number of classes per week.

A triangular prism is a three-dimensional shape with two parallel triangular bases and three rectangular faces. In this case, the triangular bases have sides of 4 cm, 5 cm, and 5 cm, while the rectangular faces have a length of 10 cm and a height of 6 cm.

To find the volume of the prism, we can use the formula V = Bh, where B is the area of the base and h is the height. The area of a triangle can be found using the formula A = 1/2bh, where b is the base and h is the height.

So, for the triangular base of this prism, we have:

A = 1/2(4 cm)(3 cm) = 6 cm²

The height of the prism is 5 cm, so:

V = Bh = (6 cm²)(5 cm) = 30 cm³

Therefore, the volume of the prism is 30 cubic centimeters.

To find the surface area of the prism, we need to calculate the area of each face and add them up.

The two triangular faces each have an area of:

A = 1/2(4 cm)(5 cm) = 10 cm²

And the three rectangular faces each have an area of:

A = (10 cm)(6 cm) = 60 cm²

So, the total surface area is:

SA = 2(10 cm²) + 3(60 cm²) = 200 cm²

Therefore, the surface area of the prism is 200 square centimeters.

The exponential function that models the total population p after t years is p = 3,500 x 1.025^t.

To write an exponential function that models the total population of the town after t years, we need to use the formula:

p = p0 x  (1 + r)^t

where p0 is the initial population, r is the annual growth rate as a decimal (so in this case, 2.5% = 0.025), and t is the number of years.

In this case, we know that the initial population is 3,500, and the annual growth rate is 2.5%, or 0.025. So we can substitute these values into the formula to get:

p = 3,500 x (1 + 0.025)^t

Simplifying this expression gives:

p = 3,500 x 1.025^t

So the exponential function that models the total population p after t years is:

p(t) = 3,500 x 1.025^t

Since the length of the actual racecar is 19 feet, and the length of the model is represented by x, we can set up the following proportion:

Length (model) / Length (actual) = Width (model) / Width (actual)

This can be written as:

x / 19 ft = 1.4 in / 7 ft

To solve for x, we can cross-multiply and simplify:

x * 7 ft = 19 ft * 1.4 in

x = (19 ft * 1.4 in) / 7 ft

x = 3.8 in

Therefore, the length of the model is 3.8 inches.

To explain this solution in more detail, we can use proportionality concepts and unit conversions. The proportion relates the length and width of the actual racecar to the length and width of the model.

We set up the proportion with the length of the model as the unknown (x) and solve for it by cross-multiplying and simplifying. Since the width of the model and actual racecar are given in different units, we convert the width of the model from inches to feet before using the proportion.

The final answer is expressed in inches, which is the same unit as the width of the model.

The required height of the trapezoid is 4 ft.

In geometry, a quadrilateral with at least one pair of parallel sides is referred to as a trapezoid in American, Canadian, and British English. In Euclidean geometry, a trapezoid is inevitably a convex quadrilateral. The trapezoid's parallel sides are referred to as its bases.

Given data;

a= 3 ft, b = 7 ft, height = h, Area = 20 sq, ft

So,

Area = (a + b)h/2

20 = (3 + 7)h/2

20 = 10h/2

2 = h/2

h = 4 ft

Thus, required height of the trapezoid is 4 ft.
