Answer:
The perimeter is 8 cm.
Yes, the perimeter of a square is directly proportional to its side length.
Step-by-step explanation:
Given:
The side length of the square is, 
The perimeter of a square is the sum of all of its side lengths. The perimeter of a square of side length 'a' is given as:
Plug in and find perimeter, 'P'. This gives,
Therefore, the perimeter is 8 cm.
Now, two quantities are directly proportional only if their ratio is a constant.
Let us find the ratio of 'P' and 'a'.
We have, 
Dividing both sides by 'a', we get:
Therefore, the ratio of perimeter and side length is a constant. Hence, these are directly proportional quantities.
Answer:
the answer is 108
Step-by-step explanation:
Answer:
The table:
x | y
2 5
3 7.5
6 15
Explanation:
Yes, Y is proportional to X and Y because it follows the equation which is
y = 5/2x
Well if its fora circle it would be r ( radios, Half of the Diameter) divided by 9
Based on the statement below, if d is the midpoint of the segment AC, the length of the segment AB is 4.5cm.
<h3>What is the line segment about?</h3>
in the question given,
AC = 3cm,
Therefore, AD and DC will be = 1.5cm segments each.
We are given C as the midpoint of segment DB.
So CB = 1.5cm.
The representation of the line segment is:
A-----------D------------C-------------B
1.5 1.5 1.5
Since AD, DC and CB are each 1.5cm segments. Then the equation will be:
= 1.5 + 1.5 + 1.5
= 4.5
Therefore, The length of the segment AB is 4.5cm.
See full question below
If D is the midpoint of the segment AC and C is the midpoint of segment DB , what is the length of the segment AB , if AC = 3 cm.
