The perimeter of inside of the track is 536.44m
<h3>Perimeter of a circle and rectangle</h3>
The perimeter of a circle is also known as the circumference of the circle. The formula for calculating the circumference is expressed as:
C = 2πr
where
r is the radius
From the given diagram
r = 46/2 = 23m
C = 2(3.14)(23)
C = 144.44m
Find the perimeter of the rectangle
P = 2(l+w)
p = 2(46+150)
P = 2(196)
P =392m
The perimeter of the inside track = 144.44 + 392
The perimeter of the inside track = 536.44m
Hence the perimeter of inside of the track is 536.44m

Answer:
11.29.
Step-by-step explanation:
We are given that The mean length of six-year-old rainbow trout in the Arolik River in Alaska is 478 millimeters with a standard deviation of 38 millimeters.
We are also given that these lengths are normally distributed.
So, The highest value is at mean .(Refer the attached figure).
Formula : 
The 54th percentile of the lengths is 11.29.
Answer:
With just the information given a perpendicular line has an opposite slope. For example the perpendicular line to x is -x. Hope this helps!
