A walkway goes through the middle of a square playground from one corner to the opposite corner. If the walkway is 20 meters long, how long are each of the sides of the playground? Round your answer to the nearest hundredths.
Need Help!
Answers
a^2 + b^2 = c^2
a^2 + a^2 = 20^2
2a^2 = 400
2a^2/2 = 400/2
a^2 = 200
a = 14.14
Thus, each sides of the playground are 14.14 meters long.

The equation of the proportional relationship represented by the table and the graph is: y = 2x.
What is a Proportional Relationship?If m is the slope or unit rate, a proportional relationship between two variables, x and y, can be represented with an equation as, y = mx.
Let's find the equation that represents the relationship represented by the graph and the table. Let's use the graph.
m = y/x
Using the point, (2, 4),
m = 4/2 = 2
Substitute m = 2 into y = mx
y = 2x
Therefore, the equation of the proportional relationship represented by the table and the graph is: y = 2x.

use the change flip method due to divide
Answer:
See step-by-step explanation.
Step-by-step explanation:
When dividing a fraction it is not actually dividing, it is more multiplying.
Our sum looks like this:
3/5 ÷ 1/3
The method here is to flip the second fraction and change the divide sign into a multiplication sign. Here is what is looks like step-by-step.
3/5 ÷ 1/3
3/5 ÷ 3/1
3/5 × 3/1
Now we can finish the sum off by multiplying across.
3 × 3 = 9
5 × 1 = 5
9/5, this is a top-heavy fraction.
If we want it as a mixed fraction then here it is:
1 4/5 (that is one and four fifths).
