x and y varies directly and the equation will be: y=480.x
Step-by-step explanation:
We need to write the equation to represent the relationship between x and y
We can find if x and y varies directly or indirectly.
Checking if x and y varies directly
if x and y varies directly then y=kx or y/x = k then k is constant
if x=2 and y=960 then k is:
k=y/x= 960/2 = 480
if x=2 and y=960 then k is:
k=y/x = 1440/3=480
if x=2 and y=960 then k is:
k=y/x= 2880/6=480
if x=2 and y=960 then k is:
k=y/x=3840/8 = 480
Since y/x = 480 for every value of y and x in the table, so x and y varies directly and the equation will be:
y= kx
y=480.x

The answer is x=40.
you subtract 80 from 180 to get the sum of y and 60, which is 100. because y doesn’t include the 60 degrees, you subtract 60 from 100.
then, you get 40 for y. because x is a vertical angle of y, you get 40 for x as well since they’re congruent to each other.

Answer:
I) There are 
hours in 1 year.
II) The exact number of hours in one year is 
hours.
Step-by-step explanation:
Given : 1 hour=3600 seconds
1 year = 31556952 seconds.
To find :
I) Use scientific notation to estimate the number of hours in one year.
1 day = 24 hours
1 year = 365 days
So, number of hours in one year is given by,
In scientific notation,
So, there are hours in 1 year.
II) 1 year = 31556952 seconds.
1 hour = 3600 seconds
In one year the number of hour is given by,
In scientific notation,
So, the exact number of hours in one year is hours.
III) In two or more complete sentences, compare your answers to parts I and II. In your comparison, discuss similarities and differences.
- The exact numbers of hours using 365 days is 8760 which is written as in scientific notation but using the given data we get hours.
- Comparing these answers the first one has only 3 significant figures and the second answer has six significant figures.
- If we round these we get
hours which has two significant numbers.
