The width of a rectangular pool is 5 meters longer than the length. The perimeter of the pool is 58 meters. Use and equation to find the pools length.
Answers
If the width is 5m longer than the length,
Then Perimeter = 2(l + 5) + 2l
= 4l + 10 {THE EQUATION}
Since Perimeter = 58 m
Then 4l + 10 = 58 m
⇒ l = 12 m
Thus the Length of the Pool = 12 m

What is direct proportion?
Direct proportion is a type of proportionality relationship. For direct proportion, as one value increases, so does the other value and conversely, as one value decreases, so does the other value.
Given that, A population of middle school students contains 160 sixth graders, 180 seventh graders, and 140 eighth graders. Nine seventh graders were part of a random sample of the population chosen to participate in a survey.
We know they are in direct proportion,
Number of sixth graders students = 160
Number of seventh graders students = 180
Number of eighth graders students = 140
If 9 seventh graders were part of a random sample of the population chosen to participate in a survey.
Let the number of sixth graders should be chosen to be 'x'.
Since, there will be direct proportion.
180/9 = 160/x
20 = 160/x
x = 160/20
x = 8
Hence, About 8 sixth graders should be chosen.
