Answer: D) The speed of light
The speed of light is approximately meters per second.
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.
Solution:
<u>Make the denominators equivalent and solve.</u>
- => 5/8 - 1/10
- => 25/40 - 4/40
- => 21/40 ≈ 1/2

Answer:
Table C
Step-by-step explanation:
Given
Table A to D
Required
Which shows a proportional relationship
To do this, we make use of:
Where k is the constant of proportionality.
In table (A)
x = 2, y = 4
x = 4, y = 9
Both values of k are different. Hence, no proportional relationship
In table (B)
x = 3, y = 4
x = 9, y = 16
Both values of k are different. Hence, no proportional relationship
In table (C):
x = 4, y = 12
x = 5, y = 15
x = 6, y = 18
This shows a proportional relationship because all values of k are the same for this table
