Answer:
perimeter = 6w + 5 units
Explanation:
Perimeter of a rectangle can be calculated as follows:
Perimeter = 2(width + length)
We are given that:
width = w units
length is 5/2 units greater than twice the width. This means that:
length = 2w + 5/2
Now, substitute in the above equation to get the expression for the perimeter as follows:
Perimeter = 2(width + length)
Perimeter = 2(w + 2w + 5/2)
Perimeter = 2(3w + 5/2)
Perimeter = 2(3w) + 2(5/2)
Perimeter = 6w + 5
Hope this helps :)
The association between flow rate and amount of eroded soil is positive because as the flow rate increases the amount of eroded soil also increases.
Step 1
Find what is 1/3 of 540
Since 20 minutes is <em>one-third of 1 hour</em>, and the speed here is measured in "Miles Per Hour". So that's why, we will divide by 3 to get our answer.
To find what's 1/3 of 540, we will divide 540mph by 3
<h2>Hence, the airplane travels 180 Miles in 20 minutes if it travels at a constant speed of 540mph</h2>
