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:

3/5      1/10

Step-by-step explanation:

1/5 divided by 1/3 is 1/5 times 3 which is 3/5

1/2 divided by 5

= 1/2 divided by 5/1

=1/2 times 1/5

=1/10

Answer:   1) 3/5     2) 1/10

Step-by-step explanation:

1) 1/5 divided by 1/3

then you take the reciprocal so the equation is now 1/5 times 3/1

and you get an answer of 3/5

2) 1/2 divided 5/1 (you put the one under the 5 cuz it's a whole number)

Take the reciprocal of the second fraction and flip the numerator and denominator so you get 1/5.

Then, do 1/2 x 1/5 which equals 1/10.

Hope that helped! :)

Which statements are true? Select all that apply.
The graph of the function will not form a straight line, so it is nonlinear.
The function is not proportional.
The function goes through the origin.
The difference between consecutive output values is a constant.

Answers

Answer:

1st 2nd and 3rd box

Step-by-step explanation:

1. It does not form a straight line because the output is not proportional. (it does not follow a pattern)

2. the line is not proportional because it does not follow a pattern or ratio of any kind (2468 is proportional because it follows the pattern of 2)

3. the origin is the coordinates (0,0) and the table has that labeled in the diagram therefore the graph does go through the origin

4. the output is not constant (output is 0149) because it does not show any sort of pattern. therefore the 4th box is incorrect.

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

Answer:

108 degrees

Step-by-step explanation:

By the Exterior Angle Theorem:

(2x + 1) + 63 = 5x -2

2x + 64 = 5x - 2

66 = 3x

22 = x

Now, we can plug the value of x back into the expression that represents the exterior angle to find the measure of the exterior angle:

5(22) - 2

110 - 2

108

The answer is 108 degrees. (I'm sorry your question was answered so late; I hope you got the right answer when you solved it!)
