I need help with this question! ​

You will need to multiply 15.5 by 2.3. Keep in mind that this only works because the scale is 1cm but if it was say.... 3.4cm:15.5 you wouldn't be able to use that method. Yeah so the answer is 35.65 which rounds up to →35.7← because the second decimal place is five

Answer:

35.7km

Step-by-step explanation:

The mean net worth is $1,000,000, and the median net worth is $87,000,000,000.

After Bill Gates moves into Centerville, the number of people in the town remains the same at 86,999, but the total net worth changes due to his massive wealth.

Mean Net Worth:

To calculate the mean net worth, we divide the total net worth by the number of people. The total net worth is the sum of the net worth of all individuals in Centerville.

Total Net Worth = Net Worth of 86,999 people + Net Worth of Bill Gates

Total Net Worth = 86,999 * 0 + $87,000,000,000 (Bill Gates' net worth)

Mean Net Worth = (Total Net Worth) / (Number of People)

Mean Net Worth = ($87,000,000,000) / (86,999 + 1) [Adding 1 for Bill Gates]

Median Net Worth:

The median net worth is the net worth of the middle person in the sorted list of net worth values. Since we have one extremely wealthy individual (Bill Gates) with a net worth of $87,000,000,000, he becomes the median net worth, as there are an odd number of people in Centerville.

So, after Bill Gates moves into Centerville:

Mean Net Worth = $87,000,000,000 / 87,000 = $1,000,000

Median Net Worth = $87,000,000,000

Therefore, the mean net worth is $1,000,000, and the median net worth is $87,000,000,000.

Answer:

It would be:

Step-by-step explanation:

You just subtract the regular numbers so 4.31-2.2 and keep the same scientific notation.

To find the volume of a cylinder that the cone fits exactly inside, we can use the formula for the volume of a cone. By solving for the radius and height of the cone, we can then substitute those values into the formula for the volume of a cylinder to obtain the volume.The correct option is C.

To find the volume of a cylinder that the cone fits exactly inside, we need to understand the relationship between the cone and the cylinder. The volume of a cone can be found using the formula V = (1/3) * π * r^2 * h, where r is the radius and h is the height of the cone. The volume of the cylinder is equal to the volume of the cone, so the volume of the cylinder can also be calculated using the formula V = π * r^2 * h. In this case, the volume of the cone is given as 12 cubic inches. We can set up an equation to find the radius and height of the cone using this volume, and then use those values to find the volume of the cylinder.

Let's solve for the radius and height of the cone:

1.Start with the formula for the volume of a cone: V = (1/3) * π * r^2 * h

2.Substitute the given volume of the cone as 12 cubic inches: 12 = (1/3) * π * r^2 * h

3.Cancel out the 1/3 by multiplying both sides of the equation by 3: 36 = π * r^2 * h

4.Divide both sides of the equation by π to isolate r^2 * h: r^2 * h = 36/π

5.Since we don't have enough information to solve for both r and h, we will express the height h in terms of the radius r.

6.Substitute r^2 * h with 36/π: r^2 * (36/π) = 36/π

7.Simplify the equation by canceling out the π: r^2 * (36/π) = 36/π

8.Multiply both sides of the equation by π/36: r^2 = 1/π

9.Take the square root of both sides to find the radius r: r = 1/√π

10.Now that we have the radius, we can find the height using the equation r^2 * h = 36/π: (1/√π)^2 * h = 36/π

11.Simplify the equation: h = 36

So, the radius of the cone is 1/√π and the height is 36. Using these values, we can calculate the volume of the cylinder:

1. Start with the formula for the volume of a cylinder: V = π * r^2 * h

2. Substitute the values we found for the cone into the formula: V = π * (1/         √π)^2 * 36

3. Simplify the equation: V = 36 cubic inches

the volume of the cylinder that the cone fits exactly inside is 36 cubic inches.

Therefor the correct option is C.
