The figures have corresponding sides that are proportional, therefore, they are similar figures.
<h3>What are Similar Figures?</h3>
When two figures are similar to each other, the corresponding sides are proportional to each other.
The two figures given have two opposite sides that are parallel and congruent to each other. Therefore:
DA/VS = 21/7 = 3
AB/ST = 15/5 = 3
Thus, we can conclude that since their corresponding sides are proportional, therefore, they are similar to each other.

The range of salary is (a) the range of salaries is from $38,500 to $39,800.
<h3>How to determine the salary range?</h3>
The given parameters are:
Average salary = 39,800
Vary = Less than $1300
Let the salary be x.
So, we have:
x = 39,800
When the salary varies, the equation becomes
x = 39800 - 1300
Evaluate
x = 38500
This means that the salary is from 38500 to 39800
Hence, the range of salary is (a) the range of salaries is from $38,500 to $39,800.

A rational number is defined as a number that can be written
as a ratio of whole numbers. If it can't then it isn't.
tail: 4.5x5/2=11.25, 4.5x3/2=6.75, 11.25+6.75=18
top fin: 3x2.25/2=3.375, 3x0.75/2=1.125, 3.375+1.125=4.5
bottom fin: 1x1/2= 0.5, 1x0.5/2=0.25, 0.5+0.25=0.75
nose: 4.5x2=9
between tail and body: 2.5x2=5
corners on body: 1.5x0.5/2x4=1.5
top and bottom on body: 0.5x5x2=5
body: 1.5x2+5=8, 2x2=4, 4x8=32
total: 18+4.5+0.75+9+5+1.5+5+32=75.75
