Find the area of the figure.

Answer: 31

Step-by-step explanation:

Answer:

a. Since we know the mean and median of the wingspans, we can assume that the data is approximately normally distributed. We also know the range, which is the difference between the maximum and minimum values. From this information, we can set up two equations:

Mean = (Wingspan1 + Wingspan2 + Wingspan3)/3 = 6 1/4

Median = 6

We can use the second equation to eliminate one of the variables. If the median is 6, then the middle value must be 6 as well. Let's assume that Wingspan2 = 6. Then we have:

(Wingspan1 + 6 + Wingspan3)/3 = 6 1/4

Multiplying both sides by 3 and simplifying:

Wingspan1 + Wingspan3 = 18 3/4

We also know that the range is 1 3/4, so:

Wingspan3 - Wingspan1 = 1 3/4

Solving for Wingspan3 in terms of Wingspan1:

Wingspan3 = Wingspan1 + 1 3/4

Substituting this into the previous equation:

Wingspan1 + (Wingspan1 + 1 3/4) = 18 3/4

2Wingspan1 + 1 3/4 = 18 3/4

2Wingspan1 = 17

Wingspan1 = 8 1/2

Therefore, Wingspan3 = 10 1/4. So the three bald eagles have wingspans of 8 1/2 feet, 6 feet, and 10 1/4 feet.

b. Since the mean and median of the weights are the same, we can assume that the data is exactly normally distributed. We also know the range, which is the difference between the maximum and minimum values. From this information, we can set up two equations:

Mean = (Weight1 + Weight2 + Weight3)/3 = 12.75

Median = 12.75

We can use the second equation to eliminate one of the variables. If the median is 12.75, then the middle value must be 12.75 as well. Let's assume that Weight2 = 12.75. Then we have:

(Weight1 + 12.75 + Weight3)/3 = 12.75

Multiplying both sides by 3 and simplifying:

Weight1 + Weight3 = 38.25

We also know that the range is 5 pounds, so:

Weight3 - Weight1 = 5

Solving for Weight3 in terms of Weight1:

Weight3 = Weight1 + 5

Substituting this into the previous equation:

Weight1 + (Weight1 + 5) = 38.25

2Weight1 + 5 = 38.25

2Weight1 = 33.25

Weight1 = 16.625

Therefore, Weight3 = 21.625. So the three bald eagles have weights of 16.625 pounds, 12.75 pounds, and 21.625 pounds.

Answer:

15 miles in 120 minutes

Step-by-step explanation:

We can start by using the unit rate of Alex's running speed:

5 miles / 40 minutes = 0.125 miles per minute

This means that Alex runs at a speed of 0.125 miles per minute.

To find out how many miles he can run in 120 minutes, we can multiply his speed by the number of minutes:

0.125 miles/minute × 120 minutes = 15 miles

Therefore, if Alex runs at the same rate, he can run 15 miles in 120 minutes.

This equation works for any number of dogs, as long as the rate remains constant.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

That's correct, Gabby's earnings are directly proportional to the number of dogs she walks. We can use a simple equation to represent this relationship:

Earnings = Rate x Number of Dogs

In this case, Gabby's rate is $10 per dog, so the equation becomes:

Earnings = 10 x Number of Dogs

For example, if Gabby walks 5 dogs, her earnings would be:

Earnings = 10 x 5 = $50

If she walks 8 dogs, her earnings would be:

Earnings = 10 x 8 = $80

And so on.

Therefore, This equation works for any number of dogs, as long as the rate remains constant.

The Required explanation of triangle inequality theorem has been done.

In mathematics, inequalities specify the connection between two non-equal values. Equal does not imply inequality. Typically, we use the "not equal symbol ()" to indicate that two values are not equivalent. But various inequalities are used to compare the values, whether it is less than or larger than.

The triangle inequality theorem states that for any triangle, the sum of the lengths of any two sides is always greater than the length of the third side. Mathematically, if a, b, and c are the lengths of the sides of a triangle, then a + b > c, b + c > a, and c + a > b.

This theorem is a fundamental principle in geometry and can be used to prove many other theorems related to triangles.

It is also used in everyday life, such as in designing bridges, ensuring the stability of buildings, and determining the shortest distance between two points.

The triangle inequality theorem is a powerful tool in mathematics and is a key concept for anyone studying geometry.

Answer:

triangles, we can determine if these triangles can be proven similar by using the SSS Similarity ... use AA Similarity to prove the triangles are similar.

Answer:

Step-by-step explanation:

When reflecting coordinates about the y-axis, we change the sign of the x-coordinate while keeping the y-coordinate the same.

So, for the point (4, 6), the new coordinates after reflection about the y-axis would be (-4, 6).

For the point (12, 2), the new coordinates would be (-12, 2).

For the point (-1, 0), the new coordinates would be (1, 0).

Therefore, the new coordinates after reflecting these points about the y-axis are (-4, 6), (-12, 2), and (1, 0).

Answer:

(f-g)(x) = -5x^3 + 8x - 8.

(f-g)(-2) = 16.

Step-by-step explanation:

To find (f-g)(x), we need to subtract g(x) from f(x) and simplify:

(f-g)(x) = f(x) - g(x)

= (-5x^3 - 4x^2 + 8x) - (-4x^2 + 8)

= -5x^3 - 4x^2 + 8x + 4x^2 - 8

= -5x^3 + 8x - 8

Therefore, (f-g)(x) = -5x^3 + 8x - 8.

To find (f-g)(-2), we substitute x = -2 into the expression we just found:

(f-g)(-2) = -5(-2)^3 + 8(-2) - 8

= -5(-8) - 16 - 8

= 40 - 24

= 16

Therefore, (f-g)(-2) = 16.

7 x 3 1/4 = 91/4 or 22 3/4

Step-by-step explanation:

To calculate 7 x 3 1/4, we can first convert the mixed number 3 1/4 to an improper fraction:

3 1/4 = (3 x 4 + 1) / 4 = 13/4

Then, we can multiply 7 by 13/4 as follows:

7 x 13/4 = (7 x 13) / 4 = 91/4

Therefore, 7 x 3 1/4 = 91/4 or 22 3/4 (if we want to express the answer as a mixed number).

The correct answer is a scatter plot, because it would show the association or relationship between two variables.

A scatter plot is a graph that displays values of two variables on two axes. It is used to show the relationship between the two variables and how one variable affects the other. It is also known as a scatter graph, scatter chart, scattergram, or scatter diagram. The points are plotted on a graph and can be used to identify patterns and trends in the data.

A scatter plot can be used to display the relationship between two variables, such as the weight and height of a manatee. The points on the scatter plot would represent each manatee's weight and height, and the pattern of the points can be used to see the overall relationship between the two variables. A line graph, on the other hand, is used to show how a variable changes over time between each data point given, and would not be suitable for this context as the data collected is not related to time.

Answer:

$85.00

Step-by-step explanation:

Let's first subtract the cost of the parts from the total to find the cost of the labor:

Cost of labor = Total cost - Cost of parts

Cost of labor = $576.50 - $109

Cost of labor = $467.50

We know that the technician worked for 5.5 hours, so we can find the cost of labor per hour by dividing the cost of labor by the number of hours:

Cost of labor per hour = Cost of labor / Number of hours

Cost of labor per hour = $467.50 / 5.5

Cost of labor per hour = $85

Therefore, the cost of labor per hour is $85.

The distinguishing feature of the distance between the foci and a point on the ellipse is that it is constant for all points on the ellipse.

What is an Ellipse?

In mathematics, an ellipse is a closed curve that is symmetrical about two perpendicular lines, called the major and minor axes.

The distinguishing feature of the distance between the foci and a point on the ellipse is that it is constant for all points on the ellipse. This distance is known as the focal length or eccentricity, and it is a measure of how much the ellipse deviates from a perfect circle. The sum of the distances from any point on the ellipse to the two foci is always equal to this constant distance, which can be calculated using the equation c² = a² - b², where c is the distance between the foci, and a and b are the lengths of the major and minor axes of the ellipse, respectively.

Answer:

Step-by-step explanation:

The sum of the distances between the foci and any point on an ellipse is a constant sum. This sum is equal to the length of the major axis.

An ellipse is a set of all points in a plane so that the sum of the distances from two fixed points, called the foci, is constant. d1 + d2 = 2a = constant. An ellipse is what we commonly call an oval and looks like a squashed or flattened circle. In fact, a circle is a special kind of ellipse where the foci are located at the center of the circle. Two fixed points on the interior of an ellipse are given by (0, c) and (0, -c) for an ellipse with a vertical orientation and by (c, 0) and (-c, 0) for an ellipse with a horizontal orientation. The larger denominator is the major axis; therefore, if the larger denominator is under the x2, the ellipse will have a horizontal orientation. If the larger denominator is under the y2, the ellipse will be oriented vertically. Because both the vertices and foci lie on the major axis, they will both have the same y-coordinate (if the major axis is horizontal) or the same x-coordinate (if the major axis is vertical).

The w-intercept of the line of fit is 5.05, and its meaning in terms of the scenario is that a puppy who is just born is predicted to weigh 5.05 ounces.

The intercepts are defined as an intercept that is located at the axes of the graph, which are the location or coordinates from where the line crosses.

The w-intercept of the line of fit is the value of w when d = 0, which means the weight of a puppy when it is born.

According to the equation w = 5.05 + 0.3d, when d = 0, we have:

w = 5.05 + 0.3(0) = 5.05

Therefore, the w-intercept of the line of fit is 5.05,

This means in terms of the scenario that a puppy who is just born is predicted to weigh 5.05 ounces.

The most effective action that Fatimah can take to reduce the reservoir's amount of water loss is to install an evaporation control system.

What is amount?

Amount is a term used to refer to the quantity or magnitude of something, typically in financial or numerical terms. It can refer to physical items such as money, goods, or services, as well as abstract concepts such as time, distance, or energy. The amount of something is usually determined by measuring, counting, or weighing it.

Evaporation is a major source of water loss in arid regions, as the dry air quickly absorbs the moisture from the reservoir's surface. By installing an evaporation control system, Fatimah can reduce the amount of water lost to evaporation by using a variety of strategies. These strategies can include the use of an impermeable membrane to cover the reservoir's surface, the installation of windbreaks to reduce the speed of the wind over the water, and the use of chemicals to reduce the rate of evaporation. All of these strategies can be used to drastically reduce the amount of water lost to evaporation.

The installation of an evaporation control system can also be relatively inexpensive compared to other solutions. For instance, compared to installing a new water pump system or rerouting water to the reservoir, installing an evaporation control system can be done quickly and at a lower cost. This makes it a more suitable solution for Fatimah's limited budget.

The area of the enlarged map is 75 cm². Answer: (D) 75 cm².

What is scale ?

Scale refers to the ratio of distances or sizes on a map or drawing to the actual distances or sizes of the objects they represent in the real world. It is often expressed as a ratio, such as 1:10,000 or 1/4 inch = 1 foot, and is used to create maps and drawings that accurately represent real-world objects and distances. Scales can be used to enlarge or reduce the size of a map or drawing, making it easier to view and work with.

The original area of Colorado on the map is:

Area = length x width = 4 cm x 3 cm = 12 cm²

To enlarge the map with a scale factor of 2.5, we need to multiply the length and width by 2.5:

New length = 4 cm x 2.5 = 10 cm

New width = 3 cm x 2.5 = 7.5 cm
