Answer:    Number of sand bags are 105

Step-by-step explanation:

Alright, lets get started.

The diameter of pool is given as : [tex]20 \ \text{feet}[/tex]

The radius of pool will be : [tex]r=\frac{20}{2}=10[/tex]

So the area of the pool will be:

Area = [tex]\pi r^2[/tex]

Area = [tex]\pi *10^2[/tex]

Area = [tex]100 \pi[/tex]

Area = [tex]314.16[/tex]

3 square feet is covered by 1 sand bag, so

314.16 square feet will be covered by : [tex]\frac{314.16}{3}[/tex]

So, no of sand bag = [tex]104.7[/tex]

Number of sand bags are 105  :   Answer

Hope it will help :)

The student will need 105 bags of sand.

The student asked about the necessary quantity of sand bags required to cover an area for an above ground pool. First, we need to calculate the area of the pool's base. Since the pool is circular with a diameter of 20 feet, we can use the formula for the area of a circle, which is A = [tex](\pi d^2)/4,[/tex] where d is the diameter.

The area A works out to [tex]\(A = \pi \times (20 feet)^2 / 4 = \pi \times 400 / 4 = \pi \times 100)[/tex] square feet. Assuming [tex]\pi[/tex] is approximately 3.14, the area is about 314 square feet.

Since one bag of sand covers 3 square feet, we divide the total area by the coverage area per bag: 314 square feet / 3 square feet per bag. This calculation gives us approximately 104.67 bags. Since we can't have a fraction of a bag, we need to round up to the nearest whole number. The student would therefore need 105 bags of sand to cover the area of the pool evenly.

To calculate the composite function (f ∙ g)(-1) for the functions f(x) = x² + 3 and g(x) = 4x - 3, we first find g(-1) which is -7, and then calculate f(-7) which results in 52.

To find the composite function (f ∙ g)(x), we first apply the function g to x, and then apply the function f to the result of g(x). In this case, first find g(-1) and then apply f to that result.

Initialize with g(-1), which is 4(-1) - 3. Simplifying that, we get -4 - 3, which equals -7.

Now, take the result of g(-1), which is -7, and input it into f(x) to get f(g(-1)). Thus, f(-7) = (-7)² + 3. Calculating this gives us 49 + 3, which equals 52. Therefore, (f ∙ g)(-1) = 52.

Answer:

2*2 is 4 id4

Step-by-step explanation:

The equation of the horizontal asymptote of the graph of the function y = 1/(x + 5) - 4 is y = -4.

To determine the equation of the horizontal asymptote of the given rational function y = \frac{1}{x + 5} - 4, we need to analyze the behavior of the function as x approaches infinity.

For rational functions, if the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is the x-axis, which is y = 0.

However, if there is a constant being subtracted from the fraction, as in this case, the horizontal asymptote is shifted vertically by that constant.

Since the degree of the numerator (0, as the numerator is 1 which is constant) is less than the degree of the denominator (1, since x is to the first power), and we subtract 4 from the fraction, the horizontal asymptote is y = -4.

Answer:

125 cubic inches

Step-by-step explanation:

The formula for the volume of a cube is:

[tex]V=a^3[/tex],

Where V is volume and a is edge length. Let's substitute the edge length of 5 from the problem into this formula.

[tex]V=5^3[/tex]

Now we can simplify. I will rewrite 5 cubed as 5*5*5 for simplicity.

[tex]V=5*5*5[/tex]

[tex]V=125[/tex]

So we have our volume, 125, but what does this mean? We have to figure out the units. Recall that our original unit was inches, thus the final answer is in inches. However, 125 inches does not make much sense, as we are dealing with volume, and not a line or distance. 125 cubic inches is the answer we are looking for, as cubic inches is the unit for volume deriving from inches.

Answer:

Cost per ounce = $0.07 (7 cents per ounce)

Step-by-step explanation:

Each container is 7.8 ounces and there are 24 of them in a case.

Total weight in ounce of the case is:

7.8 * 24 = 187.2 ounces

It costs $12.99 for the case, which contains 187.2 ounces. We find the cost per ounce of yogurt by dividing the total cost by total ounces in the case.

12.99/187.2 = 0.0693

Rounded to nearest cent (2 decimal places), that would be:

Cost per ounce = $0.07 (7 cents per ounce)

The unit price of the Greek yogurt is $0.07 per ounce.

To calculate the unit price, we need to divide the total cost of the case by the total number of ounces in the case.

First, we determine the total number of ounces in the case by multiplying the number of containers by the ounces per container:

[tex]\[ 24 \text{ containers} \times 7.8 \text{ ounces per container} = 187.2 \text{ ounces} \][/tex]

Next, we divide the total cost of the case by the total number of ounces to find the cost per ounce:

[tex]\[ \frac{\$12.99}{187.2 \text{ ounces}} \approx \$0.0693 \text{ per ounce} \][/tex]

Finally, we round this to the nearest cent, which gives us:

[tex]\[ \$0.0693 \text{ per ounce} \approx \$0.07 \text{ per ounce} \][/tex]

Therefore, the unit price of the Greek yogurt, rounded to the nearest cent, is $0.07 per ounce.

The expected value of an insurance policy for the company is calculated by subtracting the expected costs (probability of accident * average payout) from the premium paid by the customer. In this case, the insurance company can expect to retain $185.20 from the annual premium after estimated payouts.

The subject of this question falls under the category of Mathematics, specifically in the field of probability and expected value. The expected value of an insurance policy is calculated as the product of the probability of an event (an accident in this case) and the corresponding payout, subtracted from the cost or premium of the policy. Here the insurance company estimates a 2.4% likelihood of an accident, which is a probability of 0.024, and the average payout being $2700.

First, determine the expected payout by the insurance company, which is computed by multiplying the probability of the event by the payout: 0.024 * $2700 = $64.80.

Then subtract this from the premium to calculate the company's expected value: $250 - $64.80 = $185.20.

This means, on average, the insurance company can expect to retain $185.20 from the annual premium after accounting for the estimated payouts from accidents.

The expected value of this insurance policy for the company is approximately -$185.20.

Given information:

Likelihood of having an accident: 2.4% (expressed as a decimal, so (p = 0.024))

Average insurance payout: $2700

Annual premium charged: $250

The expected value ((E)) can be calculated as follows:

[tex][ E = (p \cdot \text{{Payout}}) - \text{{Premium}} ][/tex]

Substitute the given values: [ E = (0.024 x  2700) - 250 ]

Calculating: [ E = 64.8 - 250 = -185.2 ]

The expected value of this insurance policy for the company is approximately -$185.20.

Interpretation:

A negative expected value means that, on average, the insurance company is expected to lose money per policy sold.

In this case, the company charges a premium of $250 but expects to pay out an average of $2700 per accident. Therefore, the expected loss is $185.20 per policy.

Answer:

dimeonsion 1 should be 3x13 dimension 2 should be 6x10 dimension 2 is what chris should choose

Step-by-step explanation:

ik this is from prodigy lol

Chris should create a rectangular rose garden with dimensions 8 meters in length and 8 meters in width to use all 32 meters of garden fencing.

To begin, let's assume the rectangular garden has a length (L) and a width (W). Since the garden is enclosed by fencing on all sides, the perimeter of the garden would be equal to the total length of the fencing, which is 32 meters.

Perimeter = 2L + 2W

Since we know the perimeter is 32 meters, we can set up the equation:

32 = 2L + 2W

To maximize the area of the garden, Chris needs to find the dimensions that will yield the largest possible area for a given perimeter. The area (A) of a rectangle can be calculated using the formula:

Area = L * W

Since we know the perimeter is 32 meters:

2L + 2W = 32

Solving for L:

2L = 32 - 2W

L = 16 - W

Now, substitute this value of L into the area equation:

Area = L * W

Area = (16 - W) * W

Expand the equation:

Area = 16W - W²

Now, this equation represents the area of the rectangular rose garden in terms of its width (W). To find the value of W that maximizes the area, we can take the derivative of the area equation with respect to W and set it equal to zero:

d(Area)/dW = 16 - 2W = 0

Solving for W:

2W = 16

W = 8 meters

Now that we have the width (W), we can find the length (L) using the previously derived equation:

L = 16 - W

L = 16 - 8

L = 8 meters

Therefore, to create a rectangular rose garden with 32 meters of fencing that utilizes all the available fencing, Chris should make the length and width of the garden 8 meters each.

g(x) = x² - 5

Let the value of [tex]\frac{f}{g} (x)[/tex] = A

So, According to question

[tex]\frac{f}{g} (x)[/tex]  = [tex]\dfrac{f(x)}{g(x)}[/tex]

Or, A = [tex]\dfrac{4x + 1}{x^{2} -5 }[/tex]

So, The value of  [tex]\frac{f}{g} (x)[/tex] = A =  [tex]\dfrac{4x + 1}{x^{2} -5 }[/tex]

Hence, The value of  [tex]\frac{f}{g} (x)[/tex] is [tex]\dfrac{4x + 1}{x^{2} -5 }[/tex] Answer

Step-by-step explanation:

Company A: y = 45x + 150

Company B: y = 50x + 125

let's use the number 5 for x as an example

45(5) + 150 = 375

50(5) + 125 = 375

So both companies charge the same amount of money for food truck permits

Final answer:

To compare the monthly food truck permit costs for two companies, we create linear equations for each company's total cost over time. Company A's cost CA is modeled by CA = 150 + 45x, and Company B's cost CB is modeled by CB = 125 + 50x, where x is the number of months. By analyzing these equations, we can determine which company is more cost-effective based on the duration of the permit usage.

Explanation:

To model the cost of food truck permits for the two companies over time, we need to create a system of linear equations representing the total cost for each company. Let x represent the number of months for which the permit is needed.

For Company A, which charges a one-time fee of $150 and $45 per month, the total cost CA after x months would be:

CA = 150 + 45x

For Company B, with a one-time fee of $125 and $50 per month, the total cost CB after x months would be:

CB = 125 + 50x

Each of these equations relates the total cost to the number of months the permit is held. From these equations, one can see that Company A has a larger initial fee but a lower monthly cost compared to Company B. The break-even point, where the costs of both companies are equal, can be found by setting the equations equal to each other and solving for x:

150 + 45x = 125 + 50x

The break-even point informs at what time period both companies would cost the same for the permits, which could help in making a decision between the two options based on how long you plan to keep the food truck.

Answer:

x = 2y + 6

Step-by-step explanation:

2x - 4y = 12

2x = 4y + 12

x = 2y + 6

To solve for 'X' in the equation 2x - 4y = 12, isolate 'X' by adding 4y to both sides, resulting in the equation 2x = 4y + 12. Further, divide the entire equation by 2 to get X = 2y + 6. The final value of 'X' would depend on the value of 'Y'.

To solve for X in the equation 2x - 4y = 12, we can proceed in the following manner:

Isolate X on one side of equation. In order to do this, we add 4y to both sides of the equation, thus changing the equation to 2x = 4y + 12.

Now, to solve for X, we need to divide the entire equation by 2. Therefore, the final equation is ready: X = 2y + 6.

Thereby, you have now solved for 'X' in the equation. Kindly note that as there is a 'y' variable involved as well, the final value of 'X' would depend on the value of 'Y'.

According to the figure, I can safely assume that the 10 cm line and 15 cm line are parallel.

Thus, there are two similar triangles, one with the 10 cm bottom and 15 cm bottom, where one triangle is larger by a factor of 15/10 = 3/2

We know that the 8 cm line segment and y both join to create the side of the large triangle.

8cm + y = the side of the large triangle

Multiplying 8cm by 3/2 gives us 12, since we know the large triangle is 3/2 times larger than the smaller one.

8 + y = 12

y = 4 cm

Finding x is going to be a bit different. We know that the 6 cm line and x form the side of the larger triangle, which we know is 3/2 times larger than x.

x + 6cm = ?

The side of the larger triangle is 3/2x, thus

x + 6 = 3/2 x

Subtract both sides by x

6 = 1/2 x

Multiply both sides by 2

12 cm = x

Thus, y = 4 and x = 12.
