Given :
On a map with a scale 1: 25000 .
The area of a lake is 33.6 square centimeters.
To Find :
The actual area of the lake.
Solution :
Let, actual area of lake is A.
So,

We know , 
Area in km² is :

Hence, this is the required solution.
Answer:
Step-by-step explanation:
You need 2 columns and 4 rows of data here:
x y
1 30
2 60
3 90
4 120
Each time x increases by 1, y increases by 30, so the relationship between x and y is y = previous y + 30. This is the 3rd answer choice.
Given the equations:
5x + y = 4
x - y = 2
Convert the standard from to the slope intercept from
The slope intercept form is : y = mx + c
Where m is the slope and c is y-intercept
So, for the equation 5x + y = 4
the slope intercept form will be:

so, the slope = m = -5
and y-intercept = c = 4
The graph of the line will be as following:
For the second equation: x - y = 2
The slope intercept form is :

The slope of the line = 1
and the y-intercept = -2
The graph of the line will be as following :
