Background Information
Squares and Square Roots
A square is a 2-dimensional (2-D) shape with all four sides equal.
The total area the square covers is measured in square units.
To determine the side length of a square when given the area, the square root must be
determined.
A perfect square can be described as
Q a square with whole number sides (e.g., 1 × 1, 2 × 2, 3 × 3)
Q a number whose square root is an integer (e.g., 4 = 2 or –2)
A non-perfect square can be described as
Q a square with non-whole number sides (e.g., 1.2 × 1.2)
Q a number whose square root is not a whole number (e.g., 2)
Rounding is often used to determine the approximate square root of non-perfect
squares.

Shelley is making bows. Each bow is made using 9 inches of ribbon. Shelley needs to make 24 bows for a party. If the store sells ribbon by the foot, how many feet of ribbon does she need? answer choices: a= 18, b=19, c=23, d=216 .
Answers
Answer:
a. 18
Step-by-step explanation:
First you multiply 24 by 9 since each bow is 9 inches and she needs 24 bows.
After multiplying you should then end up with 216 in. Then convert 216 into feet which should give you 18.

Answer:
6/7-61/1
Step-by-step explanation:
HEYOOO PEEPS As skydivers fall through the air, a resisting force builds up underneath them. This air resistance decreases their acceleration toward the ground, making them reach a constant velocity as they fall. This is called terminal velocity. The average terminal velocity for a skydiver is about 200 km/hr.
This speed is much too fast for a skydiver to land safely. A safe speed for a skydiver to land at is only 30 km/hr.
Resistance from the air isn’t enough to slow down a skydiver to a safe landing speed. The skydiver needs a parachute.
2. What is the role of the parachute? Explain your reasoning.
Answers
Answer: The net force and the acceleration on the falling skydiver is upward. An upward net force on a downward falling object would cause that object to slow down. The skydiver thus slows down. As the speed decreases, the amount of air resistance also decreases until once more the skydiver reaches a terminal velocity.
Step-by-step explanation:
ur welcome
Answer:
Your parachute allows you to descend more slowly because it lowers terminal velocity by increasing your air resistance. Most parachutes are designed to create a large amount of drag and allow you to land at a safe, low speed.
Step-by-step explanation: this is just to try and contradict the other one because the other one above me doesn't really go into explaining what is the role of the parachute so hopefully this helps bettery in clarifying details in some way shape or form.
