Determine, to the nearest tenth of a meter, the radius of a sphere with a volume of 10000 cubic meters.

The length of carbon rod is needed to obtain a resistance of 10 ohms is 0.00897 or 8.97 × 10⁻³ meters.

In Mathematics and Science, the resistance of any conductor (wire) in terms of length can be calculated by using this formula:

Length = RA/ρ

Where:

By substituting the parameters, we have:

Length = Rπr²/ρ

Length = [10 × 3.142 × (0.0001)²]/3.5 × 10⁻⁵

Length = 3.142 × 10⁻⁷/3.5 × 10⁻⁵

Length = 0.00897 or 8.97 × 10⁻³ meters.

Answer:

Cost for each pound of jelly beans:  $2.75

Cost for each pound of almonds:  $3.75

Step-by-step explanation:

Let J be the cost of one pound of jelly beans.

Let A be the cost of one pound of almonds.

Using the given information, we can create a system of equations.

Given 3 pounds of jelly beans and 5 pounds of almonds cost $27:

[tex]\implies 3J + 5A = 27[/tex]

Given 9 pounds of jelly beans and 7 pounds of almonds cost $51:

[tex]\implies 9J + 7A = 51[/tex]

Therefore, the system of equations is:

[tex]\begin{cases}3J+5A=27\\9J+7A=51\end{cases}[/tex]

To solve the system of equations, multiply the first equation by 3 to create a third equation:

[tex]3J \cdot 3+5A \cdot 3=27 \cdot 3[/tex]

[tex]9J+15A=81[/tex]

Subtract the second equation from the third equation to eliminate the J term.

[tex]\begin{array}{crcrcl}&9J & + & 15A & = & 81\\\vphantom{\dfrac12}- & (9J & + & 7A & = & 51)\\\cline{2-6}\vphantom{\dfrac12} &&&8A&=&30\end{array}[/tex]

Solve the equation for A by dividing both sides by 8:

[tex]\dfrac{8A}{8}=\dfrac{30}{8}[/tex]

[tex]A=3.75[/tex]

Therefore, the cost of one pound of almonds is $3.75.

Now that we know the cost of one pound of almonds, we can substitute this value into one of the original equations to solve for J.

Using the first equation:

[tex]3J+5(3.75)=27[/tex]

[tex]3J+18.75=27[/tex]

[tex]3J+18.75-18/75=27-18.75[/tex]

[tex]3J=8.25[/tex]

[tex]\dfrac{3J}{3}=\dfrac{8.25}{3}[/tex]

[tex]J=2.75[/tex]

Therefore, the cost of one pound of jelly beans is $2.75.

Applying the inscribed angle theorem, the measure of the angle is calculated: 35°.

Recall the following based on the inscribed angle theorem:

Measure of an arc = 2(measure of inscribed angle)

Also not that half of a circle is equal to 180 degrees. Therefore, we have:

Measure of arc QR = 180 - 110 = 70 degrees.

Measure of angle QRS = 1/2(measure of arc QR)

Plug in the values:

Measure of angle QRS = 1/2(70)

Measure of angle QRS = 35°

The probability of having regular illness is (0.16) when compared to those with good sleep (0.12).

Let's calculate the probability of having regular illness given poor sleep:

P(regular illness | poor sleep) = 16% = 0.16

Now, let's calculate the probability of having regular illness given good sleep:

P(regular illness | good sleep) = 24 / (24 + 176) = 0.12

Hence, the probability of having regular illness is (0.16) when compared to those with good sleep (0.12).

Is it probability ???

The volume of a cylinder is thrice the volume of a cone with the same base and height.

The formula for the volume of a cylinder is V = πr²h, where r is the radius of the base and h is the height of the cylinder.

The formula for the volume of a cone is V = (1/3)πr²h, where r is the radius of the base and h is the height of the cone.

If we take a cone with the same base and height as a cylinder, the radius of the cone's base would be equal to the radius of the cylinder's base. Therefore, we can compare the volumes of a cylinder and a cone with the same base and height as follows:

Vcylinder = πr²h

Vcone = (1/3)πr²h

Dividing the volume of the cylinder by the volume of the cone, we get:

Vcylinder / Vcone = (πr²h) / [(1/3)πr²h]

Vcylinder / Vcone = 3

So the volume of a cylinder is three times the volume of a cone with the same base and height.

The coefficient of variation for the off-cuts lengths is 30.0%, which indicates a relatively high degree of variability in the data.

The coefficient of variation (CV) is a measure of relative variability, which is calculated by dividing the standard deviation by the mean, and expressing the result as a percentage. It is used to compare the variability of different datasets, particularly when they have different units or scales.

To calculate the CV for the off-cuts lengths in this problem, we first need to calculate the mean and the standard deviation. The mean is calculated by adding all the values together and dividing by the number of values:

Mean = (5.2 + 6.6 + 3.5 + 8.9 + 7.5 + 7.3) / 6 = 6.5 cm

Next, we need to calculate the standard deviation, which measures the dispersion of the data points from the mean. We can use the formula:

Standard Deviation = √(Σ(xi - x)² / (n - 1))

where xi is the value of each data point, x is the mean, and n is the number of data points.

Standard Deviation = √[(5.2 - 6.5)² + (6.6 - 6.5)² + (3.5 - 6.5)² + (8.9 - 6.5)² + (7.5 - 6.5)² + (7.3 - 6.5)²] / 5

Standard Deviation = 1.951 cm

Finally, we can calculate the coefficient of variation by dividing the standard deviation by the mean, and multiplying by 100 to express the result as a percentage:

CV = (1.951 / 6.5) x 100 = 30.0%

In the given equation, We can start by isolating the square root term on one side of the equation. The answer is {-2, 10}.

x + 6 - 9 = [tex]\sqrt{2x+29}[/tex]

Simplifying the left-hand side:

x - 3 = root(2x + 29)

Squaring both sides of the equation to eliminate the square root:

(x - 3)^2 = 2x + 29

Expanding the left-hand side:

[tex]x^2[/tex] - 6x + 9 = 2x + 29

Moving all the terms to one side of the equation:

[tex]x^2[/tex] - 8x - 20 = 0

We can now use the quadratic formula to solve for x:

x = (-b ± sqrt([tex]b^2[/tex] - 4ac)) / 2a

where a = 1, b = -8, and c = -20.

Substituting these values into the formula, we get:

x = (-(-8) ± sqrt([tex](-8)^2[/tex] - 4(1)(-20))) / 2(1)

Simplifying the equation:

x = (8 ± sqrt(144)) / 2

x = (8 ± 12) / 2

x2 = -2

To center the picture both horizontally and vertically on the wall, Jon should hang it 3.75 feet from the left edge of the wall and 3 feet from the top edge of the wall.

First, we need to convert the dimensions of the picture from inches to feet Width: 54 inches = 4.5 feet and Height: 24 inches = 2 feet

To center the picture horizontally, we need to find the distance between the left edge of the wall and the left edge of the picture, and then subtract this distance from the distance between the right edge of the wall and the right edge of the picture.

The difference should be zero if the picture is centered.

Distance between left edge of wall and left edge of picture = (12 ft - 4.5 ft) / 2 = 3.75 ft

Distance between right edge of wall and right edge of picture = (12 ft - 4.5 ft) / 2 = 3.75 ft

So, the picture is centered horizontally.

To center the picture vertically, we need to find the distance between the top edge of the wall and the top edge of the picture, and then subtract this distance from the distance between the bottom edge of the wall and the bottom edge of the picture.

The difference should be zero if the picture is centered.

Distance between top edge of wall and top edge of picture = (8 ft - 2 ft) / 2 = 3 ft

Distance between bottom edge of wall and bottom edge of picture = (8 ft - 2 ft) / 2 = 3 ft

So, the picture is centered vertically.

The total cost of repainting the 4 walls and floor of the pool would be $2800

Given that;

A swimming pool is in the shape of a right rectangular prism. the pool is 40 feet long,20 feet wide and 4 feet deep the cost of repainting the pool is $2.50 per square foot.

Here, The first step is to calculate the total surface area of the pool, which includes the four walls and the floor.

The area of the floor is simply the length times the width:

Area of floor = 40 ft x 20 ft = 800 square feet

The area of each of the four walls is the height times the width:

Area of each wall = 4 ft x 20 ft = 80 square feet

Since there are four walls, the total area of the walls is:

Total area of walls = 4 x 80 sq ft = 320 square feet

To find the total surface area of the pool, we add the area of the floor to the area of the walls:

Total surface area = Area of floor + Total area of walls

Total surface area = 800 sq ft + 320 sq ft = 1120 square feet

Finally, we can calculate the total cost of repainting the pool by multiplying the total surface area by the cost per square foot:

Total cost = Total surface area x Cost per square foot

Total cost = 1120 sq ft x $2.50/sq ft

Total cost = $2800

Therefore, the total cost of repainting the 4 walls and floor of the pool would be $2800
