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.


(Answer 1, 2, 3, 4 and 5 )


1. A sample of gold contains 3,800,000,000,000,000,000 atoms. Express this number in scientific notation.


2. A sample of silver contains 400,000,000,000,000 atoms. Express this number in scientific notation.


3. A sample of carbon has a mass of 0.000000000000000000034 kg. Express this mass in scientific notation.


4. A sample of silicon contains 5.23 × 10^11 atoms. Write this amount as a whole number.


5. The mass of a proton is about 1.67 × 10 -27kg. Write this mass as a whole number

A shipping fee of 5% is charged on every item purchased online.
Bumek [7]

Answer:

All three statements are true

Step-by-step explanation:

A shipping fee of 5% is charged online with every item purchased online

First let's just take each option and calculate them based on this, to see if the answers matched

Keith buys a 40 dollar book

40 x 0.05 = 2

Therefore there will be a two dollar fee on Keith's book

40 + 2 =42

The first statement is true

A chair costs $80

80 x 0.05 = 4

80 + 4 = 84

The second statement is true

George buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

The third statements are true


All three statements are true

Type the correct answer in each box. Spell all words correctly, and use numerals instead of words for numbers.
Andru [333]

Answer:

Nate made a mistake. He should have got 24 as Least common factor.

Step-by-step explanation:

Given number are 8 and 12.

To find the GCF or LCF we have to list multiples.

For LCF

  • List the multiples of each number until at least one of the multiples appears on all lists.
  • Find the smallest number that is on all of the lists.
  • This number is the LCM.

For GCF

  • List the multiples of each number until at least one of the multiples appears on all lists.
  • Find the Biggest number that is on all of the lists.
  • This number is the GCF

The least common multiple of 8 and 12 is 24.

The Greatest common multiply of 8 and 12 is 4.

Hence, Nate is wrong. Nate should have found 24.
