The other choices involve numbers that are well below the hundreds of million range, so scientific notation is not needed to shorten the number.

The speed of light is most likely to be expressed in scientific notation.

What is Scientific notation?

Scientific Notation is the expression of a number n in the form a∗10b. where a is an integer such that 1≤|a|<10. and b is an integer too. Multiplication: To multiply numbers in scientific notation, multiply the decimal numbers. Then add the exponents of the powers of 10

Given, A data of numbers which shows the various data. For instance:

The distance between your home and your schoolThe top speed that your parents' car can travelThe amount of money it costs to buy a new carThe speed of light.

Since, In 1 second, a photon travels approximately 300 million meters

The other choices involve numbers that are well below the hundreds of million range, so scientific notation is not needed to shorten the number.

Thus, only data that need to Represents by Scientific notation is Speed of Light.

Answers

Answer:

x= 28

Step-by-step explanation:

The angles both sum up to 180°. So, the equation would be: 39+(5x+1)= 180.

Step 1- Add common numbers.

(39+1)+5x= 180

40+5x= 180

Step 2- Subtract 40 to both sides.

40+5x= 180

-40          -40

5x= 140

Step 3- Divide both sides by 5.

5x= 140

5     5

x= 28

Angle T=Angle N = 120

Step-by-step explanation:

the two angle are equal ( corresponding angles)

7a+50=14a-20

7a-14a=-20-50

-7a=-70

a=70/7

a=10

the measure of angle N: 7a+50

7(10)+50

70+50=120

Angle T= 14a-20

14(10)-20=140-20=120
