9. 143/30

Step-by-step explanation:

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.

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

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
