Answer:
190 possibilities.
Step-by-step explanation:
The problem is called 20 choose 2, given by the formula for combinations
C(20,2) = 20! / (2! (20-2)!) = 190
alternatively, we can reason it this way:
there are 20 choices to choose a captain and 19 choices for an alternate captain for a total of 380 ways.
However, there are 20 choices to choose an alternate captain and 19 choices for a captain for a total of 380 ways.
Since we are essentially double counting every choice of the posts, we need to divide 380 by 2 to get 190 ways.
The glass part of the frame is an illustration of fractions
The width of each side of the frame is 5 1/4 inches
<h3>How to determine the width of each side?</h3>
The given parameters are:
- Total width = 42 inches
- Glass part = 32 1/2 inches
Represent the width of each side with x.
So, we have:
Glass part + 2x = Total width
Substitute known values
31 1/2 + 2x = 42
Subtract 31 1/2 from both sides
2x = 10 1/2
Divide both sides by 2
x = 5 1/4
Hence, the width of each side of the frame is 5 1/4 inches

Answer:
In mathematics, an inverse function (or anti-function) is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g(y) = x.
