The final statement is: The volume of box be is equal to 8 m³
What is a volume in math?Every three-dimensional object occupies some space. This space is measured in terms of its volume. Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.
Given here: Volume of Box A= 64 m³
Let the dimensions of box be a each
Then we have dimensions of box b are a/2 each
Therefore volume of box b is = a/2×a/2×a/2
=a³/8
= 64/8
=8
Hence, The volume of box be is equal to 8 m³

The measurement from least to greatest is: 6 pints, 2 galloons, 18 cups, 6 quart.
How would the tables be filled?In order to fill the tables, the unit of conversion has to be known:
1 gallon = 4 quart
2 gallon = 2 x 4 = 8 quarts5 gallons : 5 x 4 = 20 quarts7 gallons: 7 x 4 = 28 quarts1 quart = 2 pints
6 pint / 2 = 3 quarts
12 / 2 = 6 quarts
8 x 2 = 16 pints
How to order the measurment from least to largest?
In order to order the measurement, all the measurements have to be in the same units. All the units would be converted to cups
1 quart = 4 cups
4 x 6 = 24 cups

Pls Help
Answer:
[tex]x=\frac{3\pi }{4} ,\frac{7\pi }{4}[/tex]
If wrong then [tex]x=-\frac{\pi }{4}.[/tex]
Step-by-step explanation:
[tex]tan^2(x)-tan(x)=0[/tex]
Factor out the tan(x).
[tex]tan(x)*(tan(x)-1)=0[/tex]
Solve for x.
[tex]tan(x)\neq 0\\[/tex] thus only option is tan(x)-1=0
[tex]tan(x)-1=0\\tan(x)=1\\[/tex]
x=tan^-1(1)⇒
Either it is Quadrant 2 or 4.
[tex]x=\frac{3\pi }{4} ,\frac{7\pi }{4}[/tex]
If the teacher says its wrong. Then that could only mean that its range of tan(x) is between [tex]-\frac{\pi }{2} < x < \frac{\pi }{2}[/tex] thus it's only on quadrant 4. [tex]x=-\frac{\pi }{4}[/tex]
Use the zero product property to find the solutions to the equation x? + 12 = 7x.
X= -4 orx= 3
4 or X = -3
X=-30rX=4
X=30rX=4
Answer:
(d) x = 3 or x = 4
Step-by-step explanation:
The zero product property can be used to find the solutions to a polynomial equation when it is written in factored form.
__
Your polynomial can be put in factored form like this:
x² +12 = 7x . . . . . given
x² -7x +12 = 0 . . . . . standard form
(x -3)(x -4) = 0 . . . . . factored form*
x = 3 or x = 4 . . . . . . values of x that make the factors zero
_____
* The constants in the binomial factors must have a sum of -7 and a product of +12. It is often convenient to find them by listing factor pairs of 12:
12 = (-1)(-12) = (-2)(-6) = (-3)(-4)
Negative factors are used because we know the sum must be negative. Both have the same sign so their product is positive. The sums of the pairs shown are -13, -8, -7. The last pair is what we're looking for.
Question 1,2, and 3 how do i factor those? Can you show the work and explain how?
1: [tex]3n^{2}+9n+6[/tex]
notice that each part is divisible by 3
[tex]3n^{2}[/tex] ÷ 3 = [tex]n^{2}[/tex]
9n ÷ 3 = 3n
6 ÷ 3 = 2
so it becomes [tex]3(n^{2} +3n+2)[/tex]
3n can be rewritten as 2n+n
-you want to rewrite it into two numbers that multiply to the number that's alone (in this case 2)
which would get you
[tex]3(n^{2} +2n+n+2)[/tex]
Now that it's rewritten, you can factor out n + 2 from the equation.
the answer is
3(n+2)(n+1)
And you can check that by multiplying (n+2)(n+1) which is [tex]n^{2} +2n+n+2[/tex] and then each of those by 3, which is [tex]3n^{2} +6n+3n+6[/tex] or [tex]3n^{2}+9n+6[/tex], our origional equation
2: [tex]28+x^{2} -11x[/tex]
So I rewrote this as [tex]x^{2} -11x+28[/tex] (it's the same thing, just reordered using the commutative property)
now -11x can be rewritten as -4x-7x
(remember, the two numbers should multiply to equal 28, which is our constant.)
[tex]x^{2} -4x-7x+28[/tex]
now we can factor out x from the first expression and -7 from the second
[tex]x(x-4)-7(x-4)[/tex]
and lastly you factor out x-4,
which would give you
(x-4)(x-7)
Make sure to check your work and make sure it multiplies to [tex]x^{2} -11x+28[/tex]
3: [tex]9x^{2} -12x+4[/tex]
The first thing I notice when looking at this problem is that both 9 and 4 are perfect squares. Not only that, but they are the squares of 2 and 3, which are products of -12
So if you rewrite 9 as [tex]3^{2}[/tex] and 4 as [tex]2^{2}[/tex], the equation becomes
[tex]3^{2} x^{2} -12x+2^{2}[/tex]
now that [tex]3^{2} x^{2}[/tex] is ugly so it can be turned into [tex](3x)^{2}[/tex]
and -12x can be rewritten as [tex]-2*3x*2[/tex]
so our equation now looks like [tex](3x)^2-2*3x*2+2^{2}[/tex]
There's a rule that says [tex]a^{2} -2ab+b^{2} = (a-b)^{2}[/tex]
In our case, a=3x and b=2
so the final answer is
[tex](3x-2)^2[/tex]

The cost of painting a wall that is 5 meters wide and 212 meters tall is $50. How many square meters can be painted for $1?
Answer:
21.2 square meters
Step-by-step explanation:
The area of a parallelogram is base • height.
So:
1. Calculate the area of what you can get for $50. 5 • 212 = 1060 square meters.
2. Now you divide the first price ($50) by the desired price ($1). This one is easy because 50 / 1 = 50, but I'm putting this here for future reference in case you need to solve a problem that has a desired price that's greater than $1.
3. Divide the answer to step one by the answer to step two to get the area you can have painted for $1. 1060 / 50 = 21.2 square meters.

The location final image from the mirror, which is made when an object is placed 1.00 m to the left of the lens, is 0.58 right to the mirror.
What is the focal length of the lens?The focal length of the lens is the length of the distance between the middle of the lens to the focal point.
It can be find out using the following formula as,
[tex]-\dfrac{1}{v}+\dfrac{1}{u}=\dfrac{1}{f}[/tex]
Here, (v)is the distance of the image, (u) is the distance of the object, and (f) is the focal length of the lens.
The lens and mirror in the Figure are separated by 1.00 m and have focal lengths of +79.2 cm and -50.6 cm, respectively. Change the units of focal length in meters,
[tex]f_l=79.2\text{ cm=0.792 m}\\f_m=-50.6\text{ cm=0.506 m}[/tex]
An object is placed 1.00 m to the left of the lens. Put the value in the lens formula as,
[tex]-\dfrac{1}{v_l}+\dfrac{1}{1}=\dfrac{1}{0.792}\\-\dfrac{1}{v_l}=\dfrac{1}{0.792}-1\\v_1=3.81[/tex]
The distance of the image made by lens is 3.81 meters. The distance of this image from the mirror is,
[tex]u_2=3.81-1\\u_2=2.81\rm \; m[/tex]
This distance is work as object distance for the mirror. The focal length of mirror is -0.506 m. Thus, the location of the final image is,
[tex]-\dfrac{1}{v_2}+\dfrac{1}{3.81}=\dfrac{1}{-0.506}\\\dfrac{1}{v_2}=-\dfrac{1}{3.81}-(-\dfrac{1}{0.506})\\v_2=-0.58[/tex]
Thus, the location final image from the mirror which is made when an object is placed 1.00 m to the left of the lens, is 0.58 right to the mirror.
