If a concrete column is 6 inches by 6 inches square and 8 ft. long, calculate its weight in Newtons, given a specific weight of 62.4 lb/ft3.

Answer:The new perimeter of the field is 2800 feet.

Step-by-step explanation:

The formula for determining the area of a square is expressed as

Area = 4L

Where L represents length of each side of the square.

The small farm field is a square measuring 350 ft on a side. This means that the perimeter of the field would be

Perimeter = 350 × 4 = 1400 feet.

If you double the length of each side of the field, the new length would be

350 × 2 = 700 feet.

The new perimeter of the field would be

700 × 4 = 2800 feet

Answer:

The larger sculpture is 10.0 feet tall

Step-by-step explanation:

The height of one sculpture (larger sculpture) is four times the height of the other sculpture (smaller sculpture)

Let the height of the larger sculpture be x and the height of the smaller sculpture be y

Therefore, x = 4y (y = 2.5 feet)

x = 4×2.5 feet = 10.0 feet

The larger sculpture is 10 feet tall.

To find the height of the larger sculpture, we can use the information given. We know that the smaller sculpture is 2.5 feet tall, and the larger sculpture is four times as tall. So, we can multiply the height of the smaller sculpture by 4.

Larger sculpture height = 2.5 feet × 4 = 10 feet

Therefore, the height of the larger sculpture is 10 feet.

Final answer:

The distribution of the sample means from samples of size n=600 is a normal distribution, according to the Central Limit Theorem, option C.

Explanation:

When samples of size n=600 are taken and the mean age is calculated from each sample, the distribution of sample means is best described by a normal distribution. This is due to the Central Limit Theorem which states that as the sample size becomes large (n ≥ 30 is a commonly used threshold), the sampling distribution of the sample means will tend to be normal regardless of the shape of the population distribution.

This property of the distribution of sample means applies as long as the samples are taken with replacement or if sampling without replacement, the population is at least ten times larger than the sample. In this case, with a sample size of 600, which is well above 30, we can confidently expect the distribution of sample means to follow a normal distribution.

Final Answer:

The correct simplified ratio of US to British stamps is 25 : 2, which corresponds to answer choice E.

Explanation:

To determine the ratio of US to British stamps, we must use the given ratios of US to Indian and Indian to British stamps.

The given ratio of US to Indian stamps is 5 to 2. This means for every 5 US stamps there are 2 Indian stamps. We can represent this as:

US : Indian = 5 : 2

The given ratio of Indian to British stamps is 5 to 1. This implies that for every 5 Indian stamps, there is 1 British stamp. We can write this as:

Indian : British = 5 : 1

To find the ratio of US to British stamps, we need to combine these two ratios. To do this, we should express each ratio such that the Indian stamp part of each ratio is the same. Since the ratios already have the same number of Indian stamps (5 of them), we can directly multiply the US part by the British part across these ratios.

Thus, we multiply the number of US stamps (5 from the first ratio) by the number of British stamps (1 from the second ratio):

US to British = 5 (US) * 1 (British)
US to British = 5

Since we did not have to multiply the number of British stamps by anything (they were only multiplied by 1), the British part of the ratio remains unchanged.

Next, we multiply the Indian part of the first ratio by the British part of the second ratio:

Indian to British = 2 (Indian from the first ratio) * 5 (British from the second ratio)
Indian to British = 10

Now we can combine these two results to express the US to British ratio:

US to British = 5 (US) : 10 (British)

To simplify this ratio, we divide both sides by the common factor between them. In this case, that common factor is 5. So when we divide both numbers by 5, we have:

US to British = (5/5) : (10/5)
US to British = 1 : 2

However, this is not the option given in the question. Let's revisit the calculation and see if there was an error:

The correct approach to combining the ratios is to multiply the two ratios directly:

US : Indian = 5 : 2
Indian : British = 5 : 1

Multiplying across gives us:

US : British = (5 * 5) : (2 * 1)
US : British = 25 : 2
The correct simplified ratio of US to British stamps is 25 : 2, which corresponds to answer choice E.

Answer:

bryan walked dogs for 5.8 hours

Step-by-step explanation:

if he had $52 and the walk per hour is $9

you have to divide 52/9

52/9 is 5.77777777777...

after you roud it to the nearest tenth that is 5.8

Bryan earned $9 per hour and had a $20 expense for flyers. After subtracting his expenses from his net income of $52, we can set up an equation to find the number of hours he worked, which is 8 hours.

Let h equal the number of hours Bryan walked dogs.

Calculate his earnings by multiplying h by the rate per hour, which is $9.

Subtract his expenses, which are $20 for the flyers, from his earnings to find his net income.

Set up the equation: 9h - 20 = $52.

Add $20 to both sides of the equation to isolate the term with h on one side: 9h = $52 + $20.

Simplify the right side of the equation: 9h = $72.

Divide both sides by 9 to solve for h: h = $72 ÷ 9.

Solve for h: h = 8.

Therefore, Bryan walked dogs for 8 hours to earn a net income of $52 after his $20 expense on flyers.

Answer:

The equation representing the the scenario is [tex]72+6m=144[/tex].

It will take 12 month for the company to doubled the number of employees.

Step-by-step explanation:

Given:

Number of employees in the company =72

Number of employee increase per month = 6

We need to find the number of months required to double the number of employees.

Solution:

Doubled number of employees = [tex]2\times[/tex] Number of employees = 144

Let the number of months be 'm'

So we can say that;

Doubled number of employees is equal to Current number of employees in the company plus Number of employee increase per month multiplied by number of months.

framing in equation form we get;

[tex]72+6m=144[/tex]

Hence The equation representing the the scenario is [tex]72+6m=144[/tex].

On solving the above equation we get;

we will subtract both side by 72 we get;

[tex]72+6m-72=144-72\\\\6m=72[/tex]

Dividing both side by 6 we get;

[tex]\frac{6m}{6}=\frac{72}{6}\\\\m =12[/tex]

Hence It will take 12 month for the company to doubled the number of employees.

Step-by-step explanation:

First, we need to draw the terminal position of the given angle. To do so, we need to find a point that lies on the straight line [tex] x + 2y= 0, x\geq 0 [/tex]

If we choose [tex] x = 2 [/tex] (we can do so because of the condition [tex] x \geq 0 [/tex], which means that any positive value is suitable for [tex] x [/tex]), then we have

[tex] 2 +2y = 0\implies 2 = -2y \implies y = -1 [/tex]

Therefore, the terminal side of the angle [tex] \theta [/tex]  is passing through the origin and the point  [tex] (2,-1) [/tex] and now we can draw it.

The angle  [tex] \theta [/tex]  is presented below.

The distance of the point  [tex] (2,-1) [/tex] from the origin equals

[tex]r = \sqrt{2^2 + (-1)^2} = \sqrt{5}[/tex]

Now, we can determine the values of the six trigonometric function, by using their definitions.

[tex]\sin \theta = \frac{y}r} = \frac{-1}{\sqrt{5}} \cdot \frac{\sqrt{5}}{\sqrt{5}} = -\frac{\sqrt{5}}{5}\\\\\cos \theta = \frac{x}{r} = \frac{2}{\sqrt{5}} \cdot \frac{\sqrt{5}}{\sqrt{5}} = -\frac{2\sqrt{5}}{5} \\\\\tan \theta = \frac{y}{x} = \frac{-1}{2} = -\frac{1}{2} \\\\\cot \theta = \frac{x}{y} = \frac{2}{-1} = -2\\\\\sec \theta = \frac{r}{x} = \frac{\sqrt{5}}{2} \\\\\csc \theta = \frac{r}{y} = \frac{\sqrt{5}}{-1} = -\sqrt{5}[/tex]

Answer: 95% of all people work between 7 hours and 9 hours per day and It is true.

Step-by-step explanation:

Since we have given that

Mean = 8 hours

Standard deviation = 0.5 hours

According to Empirical Rule,

at 95% confidence, it lies within 2 standard deviations  from the mean

so, lower value is given by

[tex]mean-2\times sd\\\\=8-2\times 0.5\\\\\=8-1\\\\=7\ hours[/tex]

upper value is given by

[tex]mean+2\times s.d\\\\=8+2\times 0.5\\\\=8+1\\\\=9\ hours[/tex]

Hence, 95% of all people work between 7 hours and 9 hours per day.

Therefore , it is true.

Final answer:

95% of people work between 7 and 9 hours per day according to the empirical rule of the normal distribution. The statement is true.

Explanation:

The distribution of the number of hours people spend at work per day is unimodal and symmetric with a mean of 8 hours and a standard deviation of 0.5 hours. Since the distribution is symmetric, and we are looking for the range that includes 95% of the distribution for a standard normal distribution, we can use the empirical rule. The empirical rule states that approximately 95% of the data in a normal distribution falls within two standard deviations of the mean.

To find the range, we calculate as follows:

Therefore, 95% of all people work between 7 and 9 hours per day. The statement is true.

a) t₁ = 6 h

b) t₂ = 3h

Step-by-step explanation:

Data

v1 = 12 mph

v2 = 24 mph

total time = 9 h

Process

1.- Write equations to solve the problem

d₁ = v₁t₁    ------------------ Equation l

d₂ = v₂t₂

d₁ = d₂     because the distance is the same in both directions

t₁ = t₁

t₂ = 9 - t₁

d₂ = v₂(9 - t₁)  -------------- Equation 2

- Equal both equations

    v₁t₁ = v₂(9 - t₁)

- Substitute v₁ and v₂

   12t₁ = 24(9 - t₁)

- Solve for t₁

    12t₁ = 216 - 24t₁

    12t₁ + 24t₁ = 216

              36t₁ = 216

                  t₁ = 216 / 36

                  t₁ = 6 h

- Calculate t₂

The table that shows the pattern for this question is:

Time (year) Population

  0                   40

  1                     62

  2                    96

  3                   149

  4                   231

A growing exponentially pattern may be modeled by a function of the form P(x) = P₀(r)ˣ.

Where P₀ represents the initial population (year = 0), r represents the multiplicative growing rate, and P(x0 represents the population at the year x.

Thus you must find both P₀ and r.

1) P₀

  Using the first term of the sequence (0, 40) you get:

   P(0) = 40 = P₀ (r)⁰ = P₀ (1) = P₀

Then, P₀ = 40

 2) r

Take two consecutive terms of the sequence:

You can verify that, for any other two consecutive terms you get the same result: 96/62 ≈ 149/96 ≈ 231/149 ≈ 1.55

3) Model

Thus, your model is P(x) = 40(1.55)ˣ

Probability is the possibility of an event happening,

probability = number of required outcomes/ number of possible outcomes

number of red marbles = 10

number of blue marbles = 15

The selection of two marbles  is done without replacement.

Pr( of same color) = RR or BB

which means; (the first is red and second is red) or (the first is blue and the second is blue)

OR in probability means adition while AND means multiplication.

Pr( of same color) = [tex](\frac{10}{25}*\frac{15}{24})+(\frac{15}{25}*\frac{10}{24})[/tex]

                    =[tex]\frac{1}{4} +\frac{1}{4}[/tex]

      =0.5

Probabilities are used to illustrate the chances of an event

The probability that marbles of the same color are picked is 0.50

The numbers of marbles are given as:

[tex]\mathbf{Red =10}[/tex]

[tex]\mathbf{Blue =15}[/tex]

[tex]\mathbf{Total =25}[/tex]

The probability that marbles of the same color are picked is:

[tex]\mathbf{Pr = (Red\ and\ Red) + (Blue\ and\ Blue)}[/tex]

So, we have:

[tex]\mathbf{Pr = (10/25 \times 9/24) + (15/25 \times 14/24)}[/tex]

[tex]\mathbf{Pr = (0.15) + (0.35)}[/tex]

Given one ball has been established to be orange with no replacement, there are three possible outcomes left in the urn (OO, OB, BO). Only one outcome contains both balls as orange, hence, the probability is 1/3 or approximately 0.333.

Here, we already know that one ball selected is orange from an urn containing two orange and two blue balls. There was no replacement after the first draw, reforming the context of the problem and the counts of the balls in the urn for the second draw.

For the two-draw scenario under question, there are a total of six possible outcomes: (Orange, Orange), (Orange, Blue), (Blue, Orange), (Blue, Blue) - but since we know that at least one ball is orange, the (Blue, Blue) outcome is impossible, leaving us with three valid outcomes. Among these, only one outcome has both balls Orange.

Therefore, the probability that the other ball is also orange, given that at least one is Orange, is 1/3 or approximately 0.333, assuming that all outcomes are equally likely.

We need more data about the box dimensions to calculate the savings. The formula involves multiplying the cost per square foot with the difference in surface areas and number of boxes. The idea of economies of scale isn't directly applicable in this context.

In order to answer this question, we would require additional information about the dimensions of the boxes and their surface areas. The cost difference between making boxes with different surface areas can be found by multiplying the difference in surface areas by the cost per square foot and then by the number of boxes.

The formula used would be: $1.10 (Cost per Square Foot) * Difference in Surface Areas * 900 (Number of Boxes).

In case of economies of scale, like the information provided about alarm clocks, the cost per box would decrease as the number of boxes produced increases. But this concept isn't directly applicable here as we're dealing with the material cost of the boxes, not the production cost.

The total caloric content in the serving of fish can be calculated by adding the calories from protein (200 kcal) and the calories from fat (36 kcal). Therefore, the serving of fish contains a total of 236 kcal.

To calculate the total calories in a serving of fish, we need to add the caloric content of both the protein and the fat. The protein content of the fish is 50 g, and we know that protein has a caloric value of 4 kcal/g. Thus, the total caloric content from protein is 50 g x 4 kcal/g = 200 kcal. The fat content of this serving of fish is 4 g, and fat has a caloric value of 9 kcal/g. This makes the total caloric content from fat 4 g x 9 kcal/g = 36 kcal.

To find the total caloric content of the serving, we need to add together the calories from protein and fat. So, 200 kcal + 36 kcal = 236 kcal. Therefore, the serving of fish contains a total of 236 kcal.

Answer:Robert's minimum age is 11 years.

Step-by-step explanation:

Let x represent George's age.

Let y represent Edward's age.

Let z represent Robert's age.

George is twice as old as Edward. It means that

x = 2y

Edward's age exceeds Robert's age by 4 years. It means that

z = y - 4

If the sum of the three ages is at least 56 years, it means that

x + y + z ≥ 56 - - - - - - - - - - 1

Substituting x = 2y and z = y - 4 into equation 1, it becomes

2y + y + y - 4 ≥ 56

4y - 4 ≥ 56

4y ≥ 56 + 4

y ≥ 60/4

y ≥ 15

z = y - 4 = 15 - 4

z ≥ 11

Final answer:

To find Robert's minimum age, we need to calculate the ages of Edward, George, and Robert based on the given information.

Explanation:

Minimum Age Calculation:

Let's denote the age of Edward as E, George as 2E (twice as old as Edward), and Robert as E - 4 (Edward's age exceeds Robert's by 4 years).

The sum of their ages is at least 56, so E + 2E + (E - 4) ≥ 56.

Solving the inequality, we get E ≥ 20, George's age (2E) is at least 40, and Robert's minimum age (E - 4) is at least 16.

Algebraically, x ≤ 5π - 32 solves the inequality. Graphically, the solution lies in the shaded region below the line y = 8 - x and above y = 5(8 - π) on the coordinate plane.

Algebraic Approach:

To solve the inequality 8 - x ≥ 5(8 - π), begin by distributing 5 on the right side: 8 - x ≥ 40 - 5π. Next, isolate x by subtracting 8 from both sides: -x ≥ -5π + 32. Multiply both sides by -1, and reverse the inequality sign: x ≤ 5π - 32. This gives the solution for the inequality.

Graphical Approach:

Represent the functions y = 8 - x and y = 5(8 - π) on a graph. The point of intersection is the solution to the inequality. The line y = 8 - x is a downward-sloping line passing through the point (0, 8). The line y = 5(8 - π) is a horizontal line parallel to the x-axis at a height of 5(8 - π). The shaded region below the line y = 8 - x and above y = 5(8 - π) represents the solution to the inequality.

First, you must find the pattern behind the set of data in the table shown in the question.

It is said that this is a growing exponentially pattern. Thus, the data should be modeled by a function of the form P(x) = A(B)ˣ.

And you must find both A and B.

B is the multiplicative rate of change of the function which is a constant that you can find by dividing consecutive terms:

Thus, B = 1.55

So far, you know P(x) = A (1.55)ˣ

To find A, you can use P(0)=40, which drives to:

Thus, your function is P(x) = 40(1.55)ˣ

The population of moose after 12 years, is given by P(12):

Thus, round to the nearest whole number, those are 7,692 moose.
