terms of (Pi)

Angular speed is approximately 1.36 rad/sec and the linear speed of a point on the rim of the rotating wheel is approximately 28.56 ft/sec.

How to calculate the angular speed and linear speed of a point on the rim of the rotating wheel?

The angular speed of the rotating wheel in rad/sec is given by:

angular speed = 2π × RPM / 60

where RPM is the revolutions per minute. we get:

angular speed = 2π × 13 / 60

≈ 1.36 rad/sec

The linear speed of a point on the rim of the rotating wheel in ft/sec is given by:

linear speed = radius × angular speed

where radius is the radius of the wheel. we get:

linear speed = 21 ft × 1.36 rad/sec

≈ 28.56 ft/sec

Therefore, the angular speed of the rotating wheel is approximately 1.36 rad/sec and the linear speed of a point on the rim of the rotating wheel is approximately 28.56 ft/sec.

Answer:

Answer: A, C, D, and F are polyhedra.

Chain of thought reasoning:

A. Pyramid: A pyramid is a polyhedron because its base is a polygon with four or more sides and its associated faces are triangles. Therefore, Pyramid (A) is a polyhedron.

B. Sphere: A sphere is not a polyhedron because it is not composed of flat faces connected at straight edges, thus it does not form a shape with flat faces and straight edges. Therefore, Sphere (B) is not a polyhedron.

C. Pentagonal prism: A pentagonal prism is a polyhedron because its base is a polygon with five sides and its associated faces are also polygons, resulting in a shape with flat faces and straight edges. Therefore, Pentagonal Prism (C) is a polyhedron.

D. Cube: A cube is a polyhedron because both its bases and its associated faces are polygons with four sides, resulting in a shape with flat faces and straight edges. Therefore, Cube (D) is a polyhedron.

E. Cylinder: A cylinder is not a polyhedron because it is not composed of flat faces connected at straight edges, thus it does not form a shape with flat faces and straight edges. Therefore, Cylinder (E) is not a polyhedron.

F. Cone: A cone is a polyhedron because its base is a polygon with three or more sides and its associated faces are circles or triangle, resulting in a shape with flat faces and straight edges. Therefore, Cone (F) is a polyhedron.

The correct answer is option C: Laura determines the four arithmetic means to be −7.2, 2.8, 12.6, and 22.2.

What is arithmetic sequence?

An arithmetic sequence is a sequence of numbers in which each term after the first is found by adding a fixed constant number, called the common difference, to the preceding term.

To determine the arithmetic means between two numbers, we need to find the common difference between each pair of consecutive means. The common difference is given by:

Common difference = (larger number - smaller number) / (number of means + 1)

In this case, the larger number is 32 and the smaller number is -17. Laura wants to find four means, so the number of means is 4. Therefore, the common difference is:

Common difference = (32 - (-17)) / (4 + 1) = 49 / 5 = 9.8

To find the four arithmetic means, we start with the smaller number and add the common difference successively. Therefore, the four arithmetic means are:

-17 + 9.8 = -7.2

-7.2 + 9.8 = 2.6

2.6 + 9.8 = 12.4

12.4 + 9.8 = 22.2

Therefore, the correct answer is option C: Laura determines the four arithmetic means to be −7.2, 2.8, 12.6, and 22.2.

There are 11 possible positions for the clasp, as it can be between any two adjacent charms. If we want the clasp to be between the charms of June and July, we need to count how many of these positions satisfy this condition.

Since there are 12 charms in total, we can arrange them in 12! ways. However, since the order of the charms doesn't matter except for the position of the clasp, we need to divide by 12 to account for the different arrangements of the same set of charms.

Now, we can fix the charms of June and July in their correct positions, which leaves us with 10 remaining charms to arrange. There are 10! ways to do this. However, since we want the clasp to be between the charms of June and July, we need to treat them as a single block and arrange the 10 remaining charms and this block. There are 11 ways to do this.

Therefore, the total number of arrangements where the clasp is between the charms of June and July is 11 × 10!.

The probability of the clasp being between the charms of June and July is:

P = (number of favorable outcomes) / (total number of possible outcomes)

= (11 × 10!) / (12!)

= 11/66

We can represent the possible positions of the clasp using a diagram as follows:

Answer:

The answer is option C) 4.037 x 10^7.

Step-by-step explanation:

To find out how many more people live in California than in Vermont, we need to subtract the population of Vermont from the population of California.

The population of California is 4.1 x 10^7.

The population of Vermont is 6.3 x 10^5.

Therefore, the difference in population between California and Vermont is:

4.1 x 10^7 - 6.3 x 10^5

= 4.037 x 10^7

So, about 4.037 x 10^7 more people live in California than in Vermont.

The answer is option C) 4.037 x 10^7.

The measure of the angIes in triangIe ARST are: 28 degrees, 28 degrees, 124 degrees, 124 degrees. The measure of the angIes in triangIe ANSP are: 28 degrees, 51 degrees, 101 degrees, 129 degrees.

An angIe is a geοmetric figure fοrmed by twο rays οr Iines with a cοmmοn endpοint, caIIed the vertex. AngIes are typicaIIy measured in degrees οr radians and are used tο describe the amοunt οf turn οr rοtatiοn between twο intersecting Iines οr οbjects. AngIes can be acute (Iess than 90 degrees), right (exactIy 90 degrees), οbtuse (greater than 90 degrees), straight (exactIy 180 degrees), οr refIex (greater than 180 degrees).

Here,

To find the measure of the angIes in each triangIe, we need to soIve for the vaIue of x in both equations.

For the first equation, we can simpIify it as foIIows:

x + 14 = 2x

Subtracting x from both sides, we get:

14 = x

For the second equation, we can simpIify it as foIIows:

3x + 9 = 2x + 23

Subtracting 2x and 9 from both sides, we get:

x = 14

Now that we know x = 14, we can find the measure of the angIes in each triangIe.

In triangIe ARST, we have:

angIe A = x + 14

= 14 + 14

= 28 degrees

angIe R = 2x

= 2(14)

= 28 degrees

angIe S = 180 - (angIe A + angIe R)

= 180 - (28 + 28)

= 124 degrees

angIe T = 180 - (angIe A + angIe R)

= 180 - (28 + 28)

= 124 degrees

In triangIe ANSP, we have:

angIe A = x + 14

= 14 + 14

= 28 degrees

angIe N = 3x + 9

= 3(14) + 9

= 51 degrees

angIe S = 180 - (angIe A + angIe N)

= 180 - (28 + 51)

= 101 degrees

angIe P = 180 - (angIe N)

= 180 - 51 = 129 degrees

The area of the sector rounding to the nearest tenth is C. 8377.6 [tex]cm^2[/tex].

The law of cosines is a formula used to find the length of a side or the measure of an angle in a non-right triangle (a triangle that does not have a 90-degree angle).

According to given information:

To find the area of the windshield swept by the wiper blade, we can consider it as a sector of a circle with radius equal to the length of the segment swept by the wiper blade. The length of this segment can be found using the law of cosines:

[tex]c^2 = a^2 + b^2 - 2ab cos(C)[/tex]

where a and b are the lengths of the sides adjacent to the angle C, and c is the length of the side opposite to the angle C.

In this case, we have:

a = 80 cm (length of the wiper blade)

b = 90 cm (length of the swing arm)

C = 120 degrees (angle swept by the swing arm)

Substituting these values, we get:

[tex]c^2 = 80^2 + 90^2 - 2(80)(90)cos(120)[/tex]

[tex]c^2[/tex] ≈ [tex]20418[/tex]

[tex]c[/tex] ≈ [tex]142.8 cm[/tex]

So the radius of the circle is approximately 142.8 cm. The central angle of the sector is 120 degrees, so its measure in radians is 2π/3. Therefore, the area of the sector is:

A = (1/2) * [tex]r^2[/tex] * θ

A = (1/2) * [tex](142.8)^2[/tex] *[tex](2\pi /3)[/tex]

A ≈ 8377.6 [tex]cm^2[/tex]
