Answer: d. s ≥ 23
Step-by-step explanation:
Let s be the side of the square.
We know that the perimeter of a square =4s
Let f(s)=4s
If the cardboard should have a perimeter equal to at least 92 inches, the inequality would look like

Divide both sides by 4, we get

Thus, d. is the right answer. The reasonable domain of f(s) is 
Answer:
An angle showing a turn through 1/5 of a circle is greater
Step-by-step explanation:
we know that
A complete circle represent 
so
An angle showing a turn through 1/6 of a circle is

An angle showing a turn through 1/5 of a circle is

therefore
An angle showing a turn through 1/5 of a circle is greater
