Step-by-step explanation:

The length of the radius of the circle is 4.9cm.

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point.

The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the center.

Calculation for the length of the radius of the circle-

In order to overcome this issue, we must first translate the angle from radians to degrees.

The central angle of circle is 7/6π rads = 210 degrees.

Length of the arc is 18 cm.

The formula of length of an arc is given as-

\(l_{a r c}=\frac{\theta}{360} * 2 \pi r\)

Let's change the values and find the solution.

\(\begin{aligned}&18=\frac{210}{360} * 2 \pi r \\&18=3.663 r \\&r=\frac{18}{3.663} \\&r=4.9 \mathrm{~cm}\end{aligned}\)

Therefore, the length of the radius of the circle is 4.9 cm.

Each twelve-inch square tile weighs approximately 27 ounces.

To calculate the weight of each tile in ounces, we need to convert the weight of the box from pounds to ounces and divide it by the number of tiles in the box. Since there are 16 ounces in a pound, the weight of each box is 36 pounds * 16 ounces/pound = 576 ounces.

If there are 20 tiles in each box, we divide the weight of the box (576 ounces) by the number of tiles (20) to get the weight of each tile: 576 ounces / 20 tiles = 28.8 ounces. Rounding to the nearest ounce, each twelve-inch square tile weighs approximately 27 ounces.

Answer: Answer should be C

Step-by-step explanation: I had this question on my math test and it was C for me

The area of the figure is 825 and its unit is units squared

The given figure is a trapezium. Area of trapezium(A) = 1/2(a+b)h

Considering the labelling on the image  attached:

The distance h spans from -15 to 18. Thus h = 18 - (-15) = 18+15 = 33 units

The distance a spans from -15 to 6. Thus a = 6 - (-15) = 6 +15 = 21 units

The distance b span from -15 to 18. Thus b = 24 - (-15) = 18+15 = 39 units

Note: each square of the graph is 3. You can also get the distance by counting number of squares and then multiply by 3.

Now, Area(A) = 1/2(21+39) x 33

                        = 1/2(50) x 33

                        = 25 x 33 = 825 squared units

Therefore, the area of the composite figure is 825 and the unit is units squared

Answer:

Step-by-step explanation:

According to the information we can infer that Dora's conclusion may be incorrect because the information provided only states that the number of people who spent time reading falls within specific ranges (0-2 hours, 2-4 hours, and 2-10 hours), but it does not give a specific count for those who spent at least 4 hours. Therefore, Dora's assumption that "most people spent at least 4 hours a week reading" is not supported by the given data.

The range of the time spent reading cannot be determined from the information provided because the ranges are overlapping. For example, a person who spent exactly 2 hours reading could fall into both the first range (0-2 hours) and the second range (2-4 hours). Without more specific data or non-overlapping ranges, it is not possible to determine the exact range of time spent reading.

To estimate the mean time spent reading by Dora's friends, we can calculate the midpoint of each range and use it as an approximate value. The midpoint for the first range (0-2 hours) is 1 hour, for the second range (2-4 hours) is 3 hours, and for the third range (2-10 hours) is 6 hours. We can then calculate the estimated mean by taking the weighted average of these midpoints using the respective number of people as weights.

Estimated mean = [(4 * 1) + (5 * 3) + (11 * 6)] / (4 + 5 + 11) = 4.53 hours (approximately)

So, an estimate of the mean time spent reading by Dora's friends is approximately 4.53 hours.

The population parameter being estimated is the confidence coefficient.

The confidence coefficient is the confidence level stated as a proportion, rather than as a percentage. For example, if you had a confidence level of 99%, the confidence coefficient would be . 99. In general, the higher the coefficient, the more certain you are that your results are accurate.

probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Hence, The probability that the interval estimation procedure will generate an interval that does not contain the actual value of the population parameter being estimated is the confidence coefficient.

In an elliptical orbit with an inverse-square-law-force field, if the ratio of maximum to minimum angular velocity is n₂, then the eccentricity ß is given by B = √√(n - 1)/(√(n + 1)).



In an elliptical orbit with an inverse-square-law-force field, the angular momentum is conserved. Using the conservation of angular momentum, we can relate the maximum and minimum values of the angular velocity.

Let r_max and r_min be the maximum and minimum distances from the particle to the center of force, respectively. The angular momentum is given by L = m r^2 ω, where m is the mass of the particle and ω is the angular velocity.

At the maximum distance, r_max, the particle moves at the minimum angular velocity, ω_min. Similarly, at the minimum distance, r_min, the particle moves at the maximum angular velocity, ω_max. Therefore, we have:m r_max^2 ω_min = m r_min^2 ω_max

Simplifying the equation:

(ω_max/ω_min) = (r_max/r_min)^2 = (1 + ß)/(1 - ß)

Here, ß represents the eccentricity of the elliptical orbit.

Given that Omaz = n₂ Omin, we can substitute ω_max = n₂ ω_min into the equation:

n₂ = (1 + ß)/(1 - ß)

Solving for ß:

ß = (n₂ - 1)/(n₂ + 1)

Taking the square root of both sides:

√ß = √((n₂ - 1)/(n₂ + 1))

Simplifying further:

√ß = √√(n - 1)/(√(n + 1))

Therefore, the eccentricity ß is given by B = √√(n - 1)/(√(n + 1)).

What is algebra ?

Algebra is the study of variables and the rules for manipulating these variables in formulas; it is a unifying thread of almost all of mathematics.

To find the total time Karen spent riding her bike and swimming in the race, you need to add the time she spent riding her bike and the time she spent swimming.

Karen rode her bike for 1 1/2 hours, which is equivalent to 1.5 * 60 = 90 minutes.

She also swam for 45 minutes.

90 + 45 = 135,

Karen spent 135 minutes riding her bike and swimming in the race.

Algebra is a common thread that runs through practically all of mathematics. It involves the study of variables and the rules for manipulating them in formulas.

You must add the time Karen spent swimming and riding her bike to get the total amount of time she spent doing both during the race.

First, we need to convert Karen's bike riding time to minutes:

1 1/2 hours = 1 1/2 * 60 minutes = 90 minutes

Now we can add up Karen's bike riding time and swimming time:

90 minutes + 45 minutes = 135 minutes

So Karen spent 135 minutes riding her bike and swimming in the race.

Answer:

Jake from state farm lost 3 dollars from buying McDonalds it cost him dollars 6 how much money does he still have to pay

Step-by-step explanation:

In a simple undirected graph with 8 vertices and 27 edges, the maximum degree for a vertex is 7, since a vertex can connect to all other vertices. To determine the number of vertices that can have degree 7, we will consider the properties of simple graphs and the relationship between vertices, edges, and degrees.

In a simple graph, there are no self-loops or multiple edges between the same pair of vertices. Therefore, the maximum number of edges in a simple graph with n vertices can be calculated using the formula:

\(Max edges = n(n-1)/2\\\)

For our graph with 8 vertices, the maximum number of edges is:

Max edges = 8(8-1)/2 = 8(7)/2 = 28

Since our graph has 27 edges, it is almost a complete graph (which would have 28 edges). To figure out how many vertices can have a degree of 7, we can examine the degrees of other vertices.

If we have one vertex with degree 7, the remaining 7 vertices will be fully connected to each other, forming a complete subgraph with 7 vertices. The number of edges in this subgraph is:

Edges = 7(7-1)/2 = 7(6)/2 = 21

The total number of edges in the graph, including the vertex with degree 7, is 21 + 7 = 28. Since our graph has 27 edges, we need to remove one edge from this configuration. We can remove one edge between two of the vertices that are not the vertex with degree 7. By doing this, we maintain the degree 7 for the first vertex while reducing the degrees of two other vertices to 6.

Therefore, in a simple undirected graph with 8 vertices and 27 edges, 1 vertex can have a degree of 7.

0.29 km is equal to 290,000 mm when rounded to two significant figures.

Convert kilometers to millimeters, you need to multiply the given value by a conversion factor. In this case, since there are 1,000 meters in a kilometer and 1,000 millimeters in a meter, the conversion factor is 1,000,000 (1,000 x 1,000).

Step 1: Multiply 0.29 km by the conversion factor:

0.29 km x 1,000,000 = 290,000,000 mm

Step 2: Round the result to two significant figures:

Since the original value, 0.29 km, has two significant figures, we round the result to match.

290,000,000 mm becomes 290,000 mm.

Answer:

B

Step-by-step explanation:

Although this problem is quite long and exhausting, it is deceptively simple.

We know that his 12-gallon fuel tank is only half full, so we know that the car needs 6 more gallons of fuel.

If he turns in the car late, he will have to pay y = 2.59x + 32.00, where x is the number of empty gallons (in this case, 6)

In this case, he will pay 2.59(6) + 32.00 = $47.54

If he turns in the car on time, he will have to pay y = 4.50x + 5.00, where x is the number of empty gallons (still 6).

In this case, he will pay 4.50(6) + 5.00 = $32.00

Using these results, we know that B must be true.

Equation compares expressions. It would be cheaper for Tim to return the car on time and pay the refueling costs.

An equation is the comparison of the two expressions with help of equal to sign.

We know that if Tim takes the car to the owner he will charge him $4.50 per gallon for the fuel, while also, he needs to pay $5 as the refueling cost. Therefore, the equation that can be modeled as,

\(y = 4.50x + 5\)

Where y is the total cost of refueling at the owner's place, x is the gallons of fuel, and 5 is the fixed cost that Tim needs to pay even for a single gallon of fuel as well.

Since the fuel tank is half and its capacity is 12 gallons, therefore the total cost of refueling at the owner's place,

\(y = 4.50(6) + 5\\\\y =\$32\)

If Tim went to refuel at the station then, he will get the need to pay the late fee of $32, as well as the cost of the 6 gallons of fuel at $2.59 per gallon, therefore, the equation can be modeled as,

\(y = 2.59(6) + 532\\\\y =\$547.54\)

Hence, It would be cheaper for Tim to return the car on time and pay the refueling costs.
