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.
Step-by-step explanation:
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 .
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.

Simplified form is [tex]-4^3+36w[/tex]
Step-by-step explanation:
Is a temperature of -11 degrees warmer or colder than a temperature of -15 degrees? *
Is an elevation of -10 feet closer or farther from the surface of the ocean than an elevation of -8 feet? *
It was 8 degrees at nightfall. The temperature dropped 10 degrees by midnight. What was the temperature at midnight? *
A diver is 25 feet below sea level. After he swims up 15 feet toward the surface, what is his elevation? *
A whale is at the surface of the ocean to breathe. The whale swims down 300 feet to feed. The whale is now 300 feet below sea level. *
Assuming these are all different questions,
1. -15 is colder
2. -10 is closer than -8
3. -18
4. -10 feet
5. Not sure what you are asking, but possibly -300
-11 degrees is warmer than -15 degrees, -10 feet is closer than -8, the temperature is -2, the divers' elevation is 10 feet of elevation, and the whale goes 600 feet in all to breath, & to feed.

Answer:
6) 9216π
8) 24
Step-by-step explanation:
6)
V= 2/3πr³
r = 48/2 = 24
V = 2/3π24³
V = 9216π
8)
V = 4/3πr³
2304π = 4/3πr³
r³= (2304π)/4/3π
r³= 1728
[tex]\sqrt[3]{r^3} =\sqrt[3]{1728}[/tex]
