The Distance around the track is 400.4 meters

In order to determine the distance around a track with two straight sections and two curved ends,

we must first determine the lengths of each section.

Let us consider the given diagram.The distance of the straight section can be determined by adding the length of two opposite sides together. Let us assume that each side of the straight section measures 50 meters. Thus, the total length of the straight section is:50m + 50m = 100mTo calculate the length of the curved sections, we must first determine the radius of each section.

This can be done by dividing the diameter by 2, since the diameter is not given,

we can divide the total length of each curved section by pi (3.14) and then divide the answer by 2 to get the radius of each section.

Let's say the total length of each curved section is 150 meters, therefore, the radius is:150m / 3.14 / 2 = 23.89m (rounded to the nearest hundredth)

Therefore, the circumference of each curved section is:2πr = 2 x 3.14 x 23.89 = 150.18m (rounded to the nearest hundredth)

So, the total distance around the track is:100m + 150.18m + 150.18m = 400.36 meters (rounded to the nearest tenth).

Therefore, the distance around the track is 400.4 meters (rounded to the nearest tenth).

Answer:

11a)

A regular hexagon (6 sides) is given. Because it is regular, every interior angle has the same value.

We know that the sum of the interior angles of a triangle is 180°. Using this information, we can break this hexagon up into 4 triangles:

Given each triangle's interior angles sum to 180°, and we have 4 triangles, the total sum of the interior angles of the entire hexagon is

180*4 = 720

The sum of the interior angles of the hexagon is 720°.

11b)

The same idea can be applied:

This time a regular decagon (10 sides) is given. This shape can be broken up into 8 triangles (This value will always be the number of sides - 2).

We can now multiply to find the total sum of the interior angles.

180*8 = 1440

The sum of the interior angles of the decagon is 1440°.

(The formula to solve for interior angle sum of regular shapes is 180 * (number of sides - 2)

11c)

To find the measure of one interior angle of a regular octagon (8 sides), we must take the total sum of the interior angles and divide that by 8 (to find the value of 1 angle).

First, find the interior sum value using interior angle sum formula:

180 * (8-2) = 180 * 6 = 1080°

Now we can divide this by 8 to find the sum of one interior angle:

1080/8 = 135°

The value of one interior angle of a regular octagon is 135°.

(The formula to solve for one interior angle of a regular shape is

[180 * (number of sides - 2)] / number of sides

11d)

The sum of the exterior angles of any polygon is 360°.

An easy way to demonstrate this idea is with an equilateral triangle (every interior angle is 60°). If the interior angle is 60°, the exterior angle is 120° (supplemental theorem).

A triangle has 3 angles: 120 * 3 = 360°. The sum of exterior angles is 360°.

For a heptagon (7 sides), or any other polygon, the same result will be found.

(In order to algebraically solve this however, you would find the value of one interior angle using the formula above, subtract that value from 180 to find the value of one exterior angle, and then multiply the value of one exterior angle by 7 for a heptagon).

11e)

Given the sum of exterior angles is 360°, we can simply divide 360 by the number of sides to find the value of one exterior angle.

360 / 7 = 51.42857...

The measure of one exterior angle of the heptagon is about 51.4°.

Answer:

A rectangular prism is a three-dimensional shape that has six rectangular faces. The volume of a rectangular prism is the amount of space inside it. To find the volume of a rectangular prism, we can use the formula: V = lwh, where l is the length, w is the width, and h is the height of the prism. In this case, we are given that the height is 8 in, the width is 13 in, and the length is 18 in. Plugging these values into the formula, we get:

V = lwh

V = (18)(13)(8)

V = 1872

Therefore, the volume of the rectangular prism is 1872 cubic inches.

The mean is 46.75, the median is 40, the mode is 42, the range is 41, and the standard deviation is approximately 13.12.

To find the mean, median, mode, range, and standard deviation of the given ages, let's organize the data in ascending order:

29, 34, 35, 38, 42, 42, 64, 70

Mean:

To find the mean, we sum up all the values and divide by the total number of values:

Mean = (29 + 34 + 35 + 38 + 42 + 42 + 64 + 70) / 8

= 374 / 8

= 46.75

Median:

The median is the middle value in a sorted dataset. In this case, we have an even number of values, so we take the average of the two middle values:

Median = (38 + 42) / 2

= 40

Mode:

The mode is the most frequently occurring value. In this case, the mode is 42 since it appears twice, more than any other value.

Range:

The range is the difference between the highest and lowest values:

Range = 70 - 29

= 41

Standard Deviation:

To find the standard deviation, we need to calculate the deviations from the mean, square them, take the average, and then find the square root:

Deviation from the mean: (29-46.75), (34-46.75), (35-46.75), (38-46.75), (42-46.75), (42-46.75), (64-46.75), (70-46.75)

Squared deviations: 339.2656, 167.5625, 122.0625, 71.0625, 21.0625, 21.0625, 340.5625, 527.0625

Average squared deviation: (339.2656 + 167.5625 + 122.0625 + 71.0625 + 21.0625 + 21.0625 + 340.5625 + 527.0625) / 8

= 172.6719

Standard Deviation: √172.6719 ≈ 13.12

Therefore, the mean is 46.75, the median is 40, the mode is 42, the range is 41, and the standard deviation is approximately 13.12.

A rotation transformation is one in which the points on a geometric figure are rotated or turned about a specified point by a specified amount and direction.

The coordinates of the vertices of the triangle ΔLEO are;

L(-3, 4), E(-5, -3), O(-6, 1)

The relative coordinates of the vertices of the triangle ΔLEO to the (1, 1) are;

Relative coordinates of L ⇒ '(-3 - 1, 4 - 1) = '(-4, 3)

Relative coordinates of E ⇒ '(-5 - 1, -3 - 1), = '(-6, -4)

Relative coordinates of O ⇒ '(-6 - 1, 1 - 1) = '(-7, 0)

The coordinates of a point (x, y), following a rotation of -270° (270° clockwise) is (-y, x)

Therefore, the coordinates of the vertices of the triangle following a rotation of -270° about the point (1, 1), are;

'(-4, 3) → Rotation → ''(-3, -4)

'(-6, -4) → Rotation → ''(4, -6)

Step-by-step explanation:

An exterior angle of a triangle is formed when one side of a triangle is extended. The nonstraight angle (the one that is not just the extension of the side) outside the triangle, but adjacent to an interior angle, is an exterior angle of the triangle (Figure 1 ).

Exterior angle of a triangle.

In Figure 1, ∠ BCD is an exterior angle of Δ ABC.

Because m ∠1 + m ∠2 + m ∠3 = 180°, and m ∠3 + m ∠4 = 180°, you can prove that m ∠4 = m ∠1 + m ∠2. This is stated as a theorem.

Theorem 26: An exterior angle of a triangle is equal to the sum of the two remote (nonadjacent) interior angles.

quick clarification for a misleading material in the question

what's the second pair?  well, is a system of equations of two lines, they only meet at one point, so there's only one pair, or we can say the second pair is the same as the first pair, redundant and unnecessary, but hmmm so it's.

Answer:

Question 1:

In order to eliminate the x variables in this systems of equations problem using the elimination method, the value of x in the top and bottom equations must cancel each other out.

In order to get this to happen, we can multiply the top equation by 3 and the bottom equation by -4. This way the x value of the top equation becomes 12x and the x value of the bottom equation becomes -12x. These values would cancel each other out, letting you solve for y.

So, question 1 answer: (3, -4) OR (-3, 4)

(both will result in getting a 12x and -12x in the top or bottom that will cancel)

Question 2:

The idea from question 1 can be applied here too:

To eliminate the y variables, we must make the y values in the top and bottom equations cancel each other out.

We can multiply the top equation by 3 and the bottom equation by -7, resulting in -21y in the top equation, and 21y in the bottom equation.

So, question 2 answer: (3, -7) OR (-3, 7)

(both will result in getting a 21y and -21y in the top or bottom that will cancel)

we would expect m to be positive.

In this case, we're considering a formula of the form y = mx + b, where y represents the cost of a four-year college x years after 2010. The variable m represents the coefficient of x, which determines the slope of the line.

Since we're discussing the cost of college, it's reasonable to expect that it generally increases over time. Therefore, we would expect the coefficient m to be positive. A positive value of m indicates that as the number of years after 2010 increases (x), the cost of college (y) will also increase.

If m were negative, it would imply a decreasing cost over time, which is less likely for a four-year college. If m were zero, it would indicate that the cost remains constant regardless of the number of years after 2010, which is also unlikely given the rising trend in college costs.

The Total amount paid by Peel is $8000. Peel must remit $13,333.33 to pay the balance of the debt at the end of the credit period.

(a) To determine the amount Peel must remit to pay the balance of the debt at the end of the credit period, we need to calculate the remaining balance after the two payments.

The original invoice amount is not given in the question, so we'll calculate it using the given discounts. Let's assume the original invoice amount is X dollars.

First, let's calculate the amount after a 25% discount:

Amount after 25% discount = X - 0.25X = 0.75X

Next, let's calculate the amount after a 20% discount:

Amount after 20% discount = 0.75X - 0.20(0.75X) = 0.75X - 0.15X = 0.60X

Now, let's consider the payment on September 30 to reduce the debt to $5000:

Remaining balance after September 30 payment = 0.60X - $5000

Finally, let's consider the payment on October 20 to reduce the debt by $3000:

Remaining balance after October 20 payment = (0.60X - $5000) - $3000

To find the amount Peel must remit to pay the balance, we set the remaining balance equal to zero and solve for X:

(0.60X - $5000) - $3000 = 0

Simplifying the equation:

0.60X - $8000 = 0

0.60X = $8000

X = $8000 / 0.60

X = $13,333.33

Therefore, Peel must remit $13,333.33 to pay the balance of the debt at the end of the credit period.

(b) To find the total amount paid by Peel, we sum the two payments made by Peel:

Total amount paid = $5000 + $3000

Total amount paid = $8000

Therefore, the total amount paid by Peel is $8000.

Step-by-step explanation:

To find the shortest length of cable needed, we can use trigonometry to calculate the length of the hypotenuse of a right triangle formed by the mountain, the cable car, and the ground.

Let's denote the height of the mountain as H = 3,400 feet and the horizontal distance from the base of the mountain to the point where the cable car will be installed as D = 940 feet.

In the right triangle, the vertical leg represents the height of the mountain, the horizontal leg represents the distance from the base to the point where the cable car is installed, and the hypotenuse represents the length of the cable.

We can use the sine function to relate the angle of inclination, the height, and the hypotenuse of the triangle:

sin(angle) = opposite/hypotenuse

In this case, the angle of inclination is 74 degrees, and the opposite side is the height of the mountain (H).

Therefore, we can write the equation as:

sin(74 degrees) = H/hypotenuse

Rearranging the equation, we have:

hypotenuse = H / sin(74 degrees)

Let's calculate the value of sin(74 degrees) and substitute the values to find the length of the hypotenuse:

sin(74 degrees) ≈ 0.9613

hypotenuse = 3,400 / 0.9613 ≈ 3,535.89 feet

Therefore, the shortest length of cable needed is approximately 3,535.89 feet when rounded to two decimal places.

-4.3 = expansion

Step-by-step explanation:

The scale factor is a numerical value that expresses the proportional change in size between an original object or figure and a scaled version of it.

If the magnitude of the scale factor is greater than 1, it indicates an expansion, meaning the new size is larger than the original size.

If the magnitude of the scale factor is between 0 and 1, it indicates a contraction, meaning the new size is smaller than the original size.

If the scale factor is negative, it indicates a reflection in addition to the expansion or contraction.

[tex]\hrulefill[/tex]

As 0.75 is between 0 and 1, the scale factor of 0.75 would cause a contraction.

As 4/5 is between 0 and 1, the scale factor of 4/5 would cause a contraction.

Step-by-step explanation:

[tex]A'=\{3,6,7\}\\B'=\{2,4,6\}\\A'\cap B'=\{6\}[/tex]

Therefore, [tex]n(A'\cap B')=1[/tex].

Answer:

1 element

Step-by-step explanation:

A' means not A and B' means not B

∩ means both

so now we have how many elements are not in A and not in B

A has 1,2,4,5 so not A will be 3,6,7

B has 1,3,5,7 so not B will be 2,4,6

now we look at what not A and not B have together and that is 1 element {6}

Sherry Smith received 820 votes, the total Number of votes cast was 1000.

The total number of votes cast if Sherry Smith received 820 votes, you need to be provided with information on the percentage of votes Sherry Smith won. This is because knowing the percentage of votes Sherry Smith won would enable you to calculate the total number of votes cast, as follows:

If Sherry Smith won x percent of the total votes cast, then the total number of votes cast would be:

A total number of votes cast = (820 ÷ x) × 100We can use the formula above to calculate the total number of votes cast as follows:

If Sherry Smith won 82 percent of the total votes cast, then the total number of votes cast would be: Total number of votes cast = (820 ÷ 82) × 100Total number of votes cast = 1000 votes

Therefore, Sherry Smith received 820 votes, and the total number of votes cast was 1000.
