Answer:
Distance between two cities that are 9 inches apart on the map is 11.97 miles (12 miles)
Step-by-step explanation:
As it is given in the question scaled distance on a map is 3 inches = 4 miles.
Now we have to calculate how many miles in 1 inches on the map = 4÷3
= 1.33miles
Now we get the value of 1 inches on the map = 1.33 miles
9 inches = 1.33 × 9 = 11.97 miles ( Probably close to 12 miles if allowing for changing elevations in the distance)
In elementary school we used to refer to this as a ratio problem; two equal ratios with one containing unknown as :
X/C = A/B
X miles / 9 inches = 4 miles / 3 inches
X = 9 (4÷3)
X = 9×1.33
X = 11.97
=12 miles
If we raise a number to a power of 2, we can represent the result graphically as shown below (where n is the number to be raised to a power of 2)
This is a square of side equal to n.
Therefore, the answer is option C, squared.
Answer:
Option B is correct.
direct variation; k = 5/2
Step-by-step explanation:
The Direct variation says:

then the equation is of the form:
......[1] where k is the constant of variation.
From the given table:
Consider x = -2 and y = -5
Substitute these in [1] to solve for k;

or
5 = 2k
Divide both sides by 2 we get;

⇒ the equation becomes: 
Check:
Take x = 4 and y = 10;



10 = 10 True
Therefore, the direct variation ;
