Put these areas in size order starting with the smallest. 5.4 m² 45,000 cm² 5 x 106 mm²​

Answers

So, in order of size, from smallest to largest: 45,000 cm² < 5.4 m² = 5.4 x[tex]10^{6}[/tex] mm².

Given by the question.

To compare the areas 5.4 m², 45,000 cm², and 5 x [tex]10^{6}[/tex] mm², we need to convert them into the same unit of measurement.

1 meter (m) = 100 centimeters (cm)

1 meter (m) = 1,000 millimeters (mm)

Therefore, we can convert the given areas as follows:

5.4 m² = 5.4 x 100 x 100 = 54000 cm² (multiply by 100 twice to convert from m² to cm²)

5.4 m² = 5.4 x 1000 x 1000 = 5.4 x [tex]10^{6}[/tex] mm² (multiply by 1000 twice to convert from m² to mm²)

Now that we have converted all the areas to mm², we can compare them directly.

5.4 m² = 5.4 x 10^6 mm²

45,000 cm² = 450 x 100 = 45000 mm²

A box contains some green and yellow counters. 7/9of the box is green counters. Are 24 yellow counters. There How many green counters are there?

Answers

If 7/9 of the box is green counters, and there are 24 yellow counters in the box, then there are 84 green counters .

Let's assume that the total number of counters in the box is x.

We are given that 7/9 of the box is filled with green counters, which means that the remaining 2/9 of the box must be filled with yellow counters. We are also given that there are 24 yellow counters in the box.

We can set up an equation to represent the relationship between the number of yellow counters and the total number of counters:

2/9 x = 24

To solve for x, we can multiply both sides of the equation by the reciprocal of 2/9, which is 9/2:

(2/9) x * (9/2) = 24 * (9/2)

x = 108

This means that there are a total of 108 counters in the box. To find out how many of these are green counters, we can use the fact that 7/9 of the box is filled with green counters:

Answers

For the given relation the statement that is not correct is "X is a candidate key for R".

Given that the primary key for relation schema R(X, Y, Z) is {X, Y}, we need to determine which of the given statements is NOT correct. The possible options are:

{X, Y} is a superkey for R.

X is a candidate key for R.

Y may not have a NULL value for R.

Functional dependencies {X, Y} → Z must hold on R.

The statement that is NOT correct is: X is a candidate key for R.

A superkey is a set of attributes that, taken together, can uniquely identify a tuple in a relation schema. As per the given relation schema, {X, Y} is a superkey, because no two tuples in R can have the same value for {X, Y}.

A candidate key is a minimal superkey, meaning that it is a superkey, but removing any attribute from it would no longer make it a superkey.

In this case, {X, Y} is the only candidate key, because removing either attribute from it would make it no longer a superkey.

A NULL value is a missing or unknown data value in a tuple. As per the schema R(X, Y, Z), Y may not have a NULL value, which means that it is a non-nullable attribute, and all tuples in R must have a value for Y.

Functional dependency is a constraint between two sets of attributes in a relation schema, where one set of attributes determines the values of another set of attributes. For R(X, Y, Z), the functional dependency {X, Y} → Z must hold, which means that, for every pair of tuples in R with the same value for {X, Y}, the value for Z must also be the same.

a runner wants to run 11.7 km . she knows that her running pace is 6.7 mi/h .how many minutes must she run

Answers

The number of minutes she must run to reach her goal is 65.1 minutes.

The time she must run for is found by dividing the distance by the speed:

Time = Distance / Speed

We need to convert the distance from kilometers to miles before substituting values into the formula.

11.7 km = 11.7 / 1.609344 = 7.270043 miles

The formula now becomes:

Time = 7.270043 miles / 6.7 mi/h

Time = 1.085081 h

To get the time in minutes, we need to convert the time in hours to minutes. There are 60 minutes in an hour, so there are

assume a corporation has cumulative voting and there are two directors up for election. what is the maximum number of votes a shareholder who owns 100 shares can cast for candidate jones if there are a total of 5 candidates?

Answers

Assuming that a corporation has cumulative voting and two directors are up for election. The maximum number of votes a shareholder who owns 100 shares can cast for candidate Jones is 40.

What is cumulative voting?

Cumulative voting is a voting method used by shareholders in a company to elect a board of directors.

In this type of voting, each shareholder is given the number of votes equal to the number of shares they own, multiplied by the number of candidates. This means that if there are two candidates and a shareholder has 100 shares, then they can cast up to 200 votes for each candidate.

How to calculate the maximum number of votes for candidate Jones?

In this case, there are 5 candidates, and two directors are to be elected. Therefore, the total number of votes will be the sum of the votes required for each director, which will be 100.

The maximum number of votes that a shareholder with 100 shares can cast for each candidate will be equal to the total number of votes multiplied by the percentage of the vote that each candidate is allocated.

For example, if candidate Jones is allocated 20% of the votes, then the maximum number of votes that a shareholder with 100 shares can cast for candidate Jones will be:

Total number of votes = 2 x 100 = 200

Percentage of votes allocated to candidate Jones = 20%

Maximum number of votes for candidate Jones = 200 x 20/100 = 40.

Gail scores 153 points on average every bowling game, with a 14.5 point standard deviation. Assume Gail's bowling game points are evenly divided. With x = 108, the mean is 153, and the z-score is  -3.103.

The z-score when Gail scores 108 points in a game is calculated as:

z = (x - μ) / σ

where x = 108 is the observed score, μ = 153 is the mean, and σ = 14.5 is the standard deviation.

Plugging in the values, we get:

z = (108 - 153) / 14.5 ≈ -3.103

Answer: Felipe has walked 25.1 meters.

Step-by-step explanation:

Felipe walks the length of his living room, which is 9.1 meters. He then turns and walks the width of his living room, which is 3.5 meters. Finally, he walks back to the corner he started from, which is another 9.1 meters.

The total distance that Felipe has walked is the sum of the distances he covered in each of these three parts of his walk. So, we need to add up 9.1 meters, 3.5 meters, and 9.1 meters to get the total distance.

9.1 m + 3.5 m + 9.1 m = 21.7 m

Therefore, Felipe has walked 21.7 meters so far. However, he still needs to walk back to the corner he started from. This distance is equal to the diagonal of the rectangle formed by his living room.

We can use the Pythagorean theorem to find the length of this diagonal. The length and width of the rectangle are 9.1 meters and 3.5 meters, respectively. Let d be the length of the diagonal, then:

d² = 9.1² + 3.5²

d² = 83.06

d ≈ 9.11 meters

Therefore, the total distance that Felipe has walked is approximately:

21.7 m + 9.11 m ≈ 25.1 m

So, Felipe has walked about 25.1 meters.

Answer:

Felipe has walked 25.2 meters in total.

Step-by-step explanation:

To find out how far Felipe has walked, we need to calculate the perimeter of his living room. The perimeter is the distance around the outside of a shape.

The formula for the perimeter of a rectangle is:

perimeter = 2(length + width)

Given that the length of Felipe's living room is 9.1 meters and the width is 3.5 meters, we can substitute these values into the formula and get:

perimeter = 2(9.1 + 3.5)

perimeter = 2(12.6)

perimeter = 25.2 meters

Use the following circle to find the indicated measure.

MK
is a diameter.

Find m ∠
LKM

Answers

The answer of the given question based on finding the m∠LKM from the given circle the answer is the measure of ∠LKM is 140° degrees.

What is Diameter?

In geometry,  diameter of circle is  line segment that passes through  center of  circle and has both endpoints on circle. The diameter is the longest chord (line segment connecting two points on  circumference) of  circle. The length of  diameter is twice the length of radius, which is distance from the center of  circle to any point on  circumference.

The diameter i important property of a circle and is used to calculate other properties, like the circumference and area of the circle

Since MK is a diameter of the circle, it passes through the center of the circle, which we can label as point O. Therefore, ∠LKM is an inscribed angle that intercepts arc LM.

By the Inscribed Angle Theorem, we know that the measure of an inscribed angle is equal to half the measure of the arc that it intercepts. Therefore, to find the measure of ∠LKM, we need to find the measure of arc LM.

We are given that the measure of arc LK is 100° degrees. Since arc LM is the sum of arcs LK and KM, and MK is a diameter (so arc KM is also a semicircle with a measure of 180 degrees), we can write:

m(arc LM) = m(arc LK) + m(arc KM) = 100 + 180 = 280° degrees

Therefore, the measure of ∠LKM is:

m∠LKM = 1/2 * m(arc LM) = 1/2 * 280 = 140° degrees

So the measure of ∠LKM is 140° degrees.

An angle measures 174.8° more than the measure of its supplementary angle. What is the measure of each angle?


I need it before 3 / 11 / 23 please

Answers

Answer:

Step-by-step explanation:

Let x be the measure of the smaller angle.

Since the two angles are supplementary, we have:

x + (x + 174.8°) = 180°

Simplifying the equation gives:

2x + 174.8° = 180°

Subtracting 174.8° from both sides gives:

2x = 5.2°

Dividing by 2 gives:

x = 2.6°

Therefore, the smaller angle measures 2.6°, and the larger angle (which is supplementary) measures:

x + 174.8° = 2.6° + 174.8° = 177.4°

Answers

The marginal product of labor initially increases from 6 to 9, but then starts to decrease as more labor is added. Therefore, the firm experiences diminishing returns to labor when it hires a third laborer.

Diminishing returns to labor occur when the marginal product of labor (i.e., the additional output produced by adding one more unit of labor) decreases as more labor is added. We can calculate the marginal product of labor for each level of labor as follows:

1 laborer: 6 units of output (marginal product = 6)

2 laborers: 9 units of additional output (total output = 15, marginal product = 9)

3 laborers: 10 units of additional output (total output = 25, marginal product = 10)

4 laborers: 9 units of additional output (total output = 34, marginal product = 9)

The law of diminishing marginal returns is a concept from economics that explains how the marginal output of a production process starts to decrease as the input goes up. It is also used to refer to a point at which output increases at a diminishing rate as more units of labor are added to a production process. This can also be called the point of decreasing marginal productivity.

What precisely is a surface area?

Its total size can be determined by figuring out how much room would be required to completely cover the outside. When choosing comparable substance with a rectangular shape, the surroundings are taken into account. Something's total dimensions are determined by its surface area. The volume of water that a cuboid can contain depends on the number of edges that are present in the region between its four trapezoidal angles.

Here,

We are aware that this total area is equivalent to the white cross's area times four.

Therefore:

Total flag area minus the crimson background area equals the area of the white cross.

=> 13,348 - 4x equals area of white cross

When we use this expression in the preceding equation as the area of the white cross, we obtain:

=>  4x + (13,348 - 4x) = 13,348

When we simplify and find x, we obtain:

=>  x = 836

As a result, the size of the white cross is: 836 mm2, the size of each parallelogram containing the fleur-de-lis is:

=> Area of white cross = Total area of flag - Area of red background

=>  13,348 - 4x

If an object is dropped from the top of a building, its position in feet above the ground is given by s(t)=−8t^2+288, where t is the time in seconds since it was dropped.  Given that an object is dropped from the top of a building,

then its initial velocity, u = 0 (since it was dropped and not thrown). We want to find the velocity when the object hits the ground, i.e., the time it takes the object to reach the ground. We know that the position of the object when it reaches the ground is s(t) = 0.

(A) The statistic is equal to the true value of the parameter it is being used to estimate for every possible sample. (B)The mean of the sampling distribution of the statistic is equal to the true value of the parameter it is being used to estimate. (C) The sampling distribution of the statistic has the same mean and standard deviation as the distribution of the population. (D)The statistic is a proportion. (E) The mean of the sampling distribution of the statistic will change as the sample size is changed.

Answers

If a statistic used to estimate a parameter is said to be unbiased, then the mean of the sampling distribution of the statistic is equal to the true value of the parameter it is being used to estimate (B).

In statistics, when a sample statistic is unbiased, it means that the statistic does not deviate from the population parameter that it is trying to estimate. The unbiased estimator is not consistently overestimating or underestimate the true population parameter value.

It is measured by the mean of the sampling distribution. In other words, if we take every possible sample of the same size n from the same population and calculate the statistic, the mean of those statistics would be equal to the true value of the parameter being estimated.

Option (A) is not true, because it is not necessary for the statistic to be exactly equal to the true value of the parameter for every possible sample, only that the average of the statistic over many samples is equal to the true value.

Option (C) is not necessarily true, as the sampling distribution of the statistic may have a different standard deviation than the population distribution.

Option (D) is not true, as unbiasedness applies to any type of statistic, not just proportions.

Option (E) is not true, as the mean of the sampling distribution of an unbiased statistic does not depend on the sample size, only on the true value of the parameter being estimated.

Therefore, the correct option is (B) The mean of the sampling distribution of the statistic is equal to the true value of the parameter it is being used to estimate.

Elena and Jada were racing on their bikes. Elena started 15 meters ahead of Jada. Elena biked at a rate of 20 meters per second. Jada biked at a rate of 22 meters per second. Let x represent time in seconds and y represent distance in meters. After how many seconds will Jada pass Elena?

Answers

Jada overtakes Elena after 7.5 seconds.

The set of equations that best captures the scenario is =y=15+20x.

Let's establish a coordinate system with Elena's starting point as the origin. Elena's separation from the origin at time x is given by: y=15+20x

y1 = 15 + 20x

Jada's distance from the origin at time x is determined similarly by:

y2 = 22x

Finding the moment x at which Jada overtakes Elena and their distances from the origin are equal is our goal.

y1 = y2

With the formulas for y1 and y2 substituted, we obtain:

15 + 20x = 22x

When we simplify this equation, we obtain:

2x = 15

x = 7.5

Jada therefore overtakes Elena after 7.5 seconds.

The number of paintings owned by an art museum was 200. Since this time, the collection of paintings has grown by 2% each month. Which expressions represent the number c
paintings owned by the art museum 2 years later if it continues to grow at this rate?
A 200-(1+0.02¹2) 24
B 200-(1.02)²
C 200- 1+0.02)¹²) ²
D 200• (1.02)^24
E 200• (0.02) ^24

Answers

Therefore , the solution of the given problem of expressions comes out to be choice D is the correct response: 200 • (1.02)24.

What is an expression ?

It is preferable to use moving numbers, which can be growing decreasing, or variable, rather than generating estimates at random. They could only assist one another by exchanging resources, knowledge, or answers to problems. A truth statement may contain strategies, components, and notations against mathematical processes such as additional denial, synthesis, and mixture.

Here,

The number of paintings in the library is increasing by 2% each month, so the growth rate for one month is 2/100 = 0.02.

Therefore, multiplying the starting number of paintings (200) by the growth factor

=>  (1 + 0.02)24,

where 24 is the number of months in 2 years, will give the number of paintings the art museum will own after two years (24 months).

Thus, the expression that denotes the number of paintings the art institution owns after two years is as follows:

=>  D) 200 • (1.02)^24

Therefore, choice D is the correct response: 200 • (1.02)24.

Which of the following equations is equivalent to 2 x + 6 = 30 - x - 3 2 x + 6 = 10 - x - 3 2 x + 6 = 30 - x + 3

Answers

The equation that is equivalent to 2x + 6 = 30 - x - 3 is option (a): 2x + 6 = 30 - x - 3.

What is equation?

In mathematics, an equation is a statement that two expressions are equal, usually written with an equal sign (=) between them. Equations can contain variables, which are symbols that represent unknown or unspecified values.

We can simplify and solve the equation 2x + 6 = 30 - x - 3 as follows:

2x + 6 = 30 - x - 3

Adding x and adding 3 to both sides, we get:

3x + 9 = 30

Subtracting 9 from both sides, we get:

3x = 21

Dividing both sides by 3, we get:

x = 7

So the given equation simplifies to x = 7.

We can now substitute this value of x into each of the answer choices to see which one is equivalent to the given equation:

a) 2x + 6 = 30 - x - 3

Substituting x = 7, we get:

2(7) + 6 = 30 - 7 - 3

14 + 6 = 20

20 = 20

b) 2x + 6 = 10 - x - 3

Substituting x = 7, we get:

2(7) + 6 = 10 - 7 - 3

14 + 6 = 0

20 ≠ 0

Therefore, this equation is not equivalent to the given equation.

c) 2x + 6 = 30 - x + 3

Substituting x = 7, we get:

2(7) + 6 = 30 - 7 + 3

14 + 6 = 26

20 ≠ 26

Therefore, this equation is not equivalent to the given equation.

Therefore, the equation that is equivalent to 2x + 6 = 30 - x - 3 is option (a): 2x + 6 = 30 - x - 3.

What is the sum of the two amounts of money shown?

Answers

Answer:

$21.39

Step-by-step explanation:

The way we notate money is by putting dollars first, and then cents at the end of the decimal.

For the first amount of money, we have 15 dollars in cash. We have 3 quarters, and each quarter is 25 cents. If we add 25 cents 3 times, we get 75 cents. We are then given 2 nickels, which are 5 cents. We add 10 to 75, and we get 85 cents.

[tex]15.85[/tex]

We are then give a singular 5 dollar bill. We also have two quarters, which are again 50 cents. Add 4 to this, and we get 54.

[tex]5.54[/tex]

Now we add the two together!
