The average surface temperature of a red giant star is much cooler than that of a white dwarf star. Suppose a white dwarf has a surface temperature of 1.2 x 10*4 Kelvin (abbreviated K), which is 4 times the temperature of a red giant star. WHat is the surface temperature of the red giant star?

Answers

Answer: 3000 Kelvin

Step-by-step explanation

Let the surface temperature of the red giant star = x

Surface temperature of a white dwarf star = 4x

4x = 1.2 × 10^4 K

    = 1.2 × 10,000 K

    = 12,000 K

4x = 12,000 K

x = 12000 ÷ 4

  = 3,000 K

A sphere has a radius of 5 feet. Find the volume of the sphere. Leave your answer in terms of pie. Then use 3.14 for pie and round the volume to the nearest 10th. Volume in terms of pie=? Volume in using 3.14=?

Answers

The Volume is 523.6
Solution: V=4
3πr3=4
3·π·53≈523.59878 and 5 or more raise the score so the 9 makes the 5 into 6 and drop all of the other numbers

The solution is, The Volume is 523.6, of the sphere has a radius of 5 feet.

What is volume?

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

here, we have,

Given,

r = 5 ft

pi = 3.14

Formula

the volume of sphere is:

V = 4/3 * 3.14 * r^3

Solution

V = 4/3  * 3.14 * 5^3

V = 4/3 * 3.14 * 125

V ≈ 523.59878

V ≈ 523.6 m^3

as, we get,

V≈523.59878

and 5 or more raise the score so the 9 makes the 5 into 6 and drop all of the other numbers.

Hence, The solution is, The Volume is 523.6, of the sphere has a radius of 5 feet.

Answers

The answer is 2.25 because the total was 13.25 and it is asking you how much he paid for the ham. So you would first subtract 2 from 13.25 which gives you 11.25 and then divide by 5 and it will give you the answer which is 2.25

Measurements of atoms, such as amounts, distances, and weights, are often very large or very small when compared to measurements of things you can see or touch. Scientific notation represents numbers as a power of 10. This makes very large or small numbers easier to use and understand. Approximately 7,500,000,000,000 carbon atoms fit across the period that you make with your pencil. Express this number in scientific notation. (PLEASE ANSWER FAST I'LL GIVE BRAINLIEST ALSO PLEASE DO ALL THIS IS WORTH 30 POINTS)


Step 1 Rewrite the number with a decimal after the first nonzero digit.7.500000000000


Step 2 Find the number of places and the direction you moved the decimal. If a number does not show a decimal, the decimal is at the right end of the number.You moved the decimal 12 places to the left.


Step 3 Drop the zeros, and write the number of places you moved the decimal as a power of 10. If you moved the decimal to the right, the power is negative. If you moved the decimal to the left, the power is positive.7.5 × 10 12


Step 4 Reverse the process to change scientific notation back to a whole number. A positive power of 10 moves the decimal to the right. A negative power of 10 moves the decimal to the left.

Step-by-step explanation:

Convert 2 meters to cm:  

2 m       100 cm

  1             1 m

Next, divide this 200 cm total length by (10 cm/section) to determine the number of sections:

The technical writer preparing a recommendation report based on the feasibility study has compiled the following information to be used in the report: Because the complex will be located in an environmentally sensitive area, the fence must visually enhance the property while blending in with its surroundings, yet at the same time adding a measure of safety. In order to keep monthly condominium dues as low as possible, the fence must not require a high degree of maintenance. Its minimum life should be 25 years, and it should cost under $70,000. The options researched were stone, vinyl, vinyl-coated iron, and wood. Both types of vinyl fencing will last up to 25 years, stone up to 50 years, and wood up to 15 years. Wood fencing must be painted or stained periodically. Maintenance for vinyl and stone fencing consists of occasionally washing with water. Based on two bids for each type of fencing, all types fall within the maximum allowable cost. Wood was cheapest, followed closely by vinyl. Stone and vinyl-coated iron were the most expensive. We think the best course of action is to have a stone wall built by Masonry Builders, Inc., to enclose the new condominium complex.
