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:
50 km
Step-by-step explanation:
So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by
2.5
1
. Then, 20 x 2.5=50. So the answer is 50 km
Answer:
D
Step-by-step explanation:
The area (A) of a kite is calculated as
A =
× d₁ × d₂ ( d₁ and d₂ are the diagonals )
This can be represented as
Multiply the diagonals then divide by 2 → D
