Zahra has paper rectangles of different sizes. every rectangle is 5 centimeters longer than it is wide. is there a proportional relationship between the lengths and widths of these rectangles? explain.

Yes, there is a proportional relationship between the lengths and widths of the rectangles.

Step-by-step explanation:

A rectangle is a quadrilateral with opposite sides to be equal. Its area can be determined by: A = length × width.

And its perimeter can be determined by: P = 2 (length + width).

Considering the given question, the paper rectangles of different sizes have a common property; each is 5 centimeters longer than its width. Therefore, the length for each is determined by the value of the width.

Thus,

     length = width + 5

⇒            l = w + 5

This expression shows the relationship between the length and widths of the rectangles.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
