How many 1-cm-diameter ball bearings can be made using 5.24 cm3 of molten steel?
Answers
V=4/3•pi•r^3 = 4/3•3.14•(.5)^3 = 0.52
5.24 / 0.52 = 10.01
So you can make 10 ball bearings out of that amount of steel.

Answers
When you sub in 1 for n you get -5(1)+9 which is 4 and when 2 is subbed in for n it is -10+9 which is -1 so it checks. After -11, the next number would be -5(5)+9= -16

Answers
The correct answers are:
They consist primarily of variables.
They are often called formulas.
They often describe real-world relationships.
Explanation:
Literal equations are defined as "equations in more than 1 variable whose variables represent specific quantities."
This means that literal equations consist mostly of variables.
Since the variables represent specific quantities, this means they typically represent real-life situations.
Since they represent real-life situations, these equations are often formulas for things in the real world (such as area, volume, perimeter, circumference, etc.)

Answer:
800 inches³
Step-by-step explanation:
∵ The volume of each cube is s³
∵ The length of the side is 2 inches
∴ The volume of the cube = 2³ = 8 inches³
∵ The prism consists of 100 cubes
∴ The volume of the prism = 100 × 8 = 800 inches³
Another method:
We divide the number of cubes to form the rectangular prism
5 cubes as a length , 2 cubes as a width and 10 cubes as height
∵ The length of the side of each cube is 2 inches
∴ The length = 5 × 2 = 10 inches
∴ The width = 2 × 2 = 4 inches
∴ The height = 10 × 2 = 20 inches
∵ The volume of the prism = L × W × H
∴ V = 10 × 4 × 20 = 800 inches³

Answer:
2y( 3x-1)(3x+1)
Step-by-step explanation:
18x^2y-2y
Factor out the greatest common factor 2y
2y( 9x^2 -1)
The term in the parentheses is the difference of squares
a^2 - b^2 = (a-b)(a+b)
2y( 3x-1)(3x+1)

The solution of the expression 7/10 - 1/4 is 9/20.
How to interpret the fraction?
Suppose the fraction is proper (the numerator is smaller than the denominator).
Let it be
Then, we can interpret it as:
= a parts out of b parts of a thing.
WE are given the expression as;
7/10 - 1/4
Now use common denominators;
28/40 - 10/40 = 18/40
= 9/20
The solution of the expression 7/10 - 1/4 is 9/20.
