How much space is inside the steps?
The space inside the steps will be 0.04 cubic meter
What is volume?The space in a three dimensional region occupied by any body is called as volume.
Assume the steps have the dimensions shown in the diagram below.
We can decompose them into two rectangular prisms.
The lower prism has the dimensions 20 in × 16 in × 6 in.
The upper prism has the dimensions 20 in × 8 in × 6 in.
1. Volume of lower prism
V = lwh = 20 in × 16 in × 6 in = 1920 in³
2. Volume of upper prism
V = lwh = 20 in × 8 in × 6 in = 960 in³
3. Volume of steps
V = 1920 in³ + 960 in³ = 2880 in³
Or the volume in meter will be 2880 cubic inches = 0.04 cubic meters.

We can identify geometric series by:
√first term x third term = second term
√125 x 5 = 25
Hence this is a geometric series.
Common difference:
25 ÷ 5 or 125 ÷ 25

It's not entirely clear what the full instructions are, and I wish your teacher posted a diagram of figures A and B. However, I think I know what your teacher is after.
I'm assuming this is pertaining to similar polygons.
The larger figure has a side length of 88 ft and corresponds to the smaller side length of 11 ft. This is a scale factor of 11/88 = 1/8 = 0.125
What it means is that we multiply each larger side length by 1/8 or 0.125 to get the smaller corresponding side length. In other words, 88*(1/8) = 11
Square this linear scale factor to get the area scale factor
(1/8)^2 = (0.125)^2 = 0.015625
This value of 0.015625 is the area scale factor. We multiply this by the area of figure A to get
4928*0.015625 = 77
This is how your teacher got 77 as the final answer for figure B.
------------------------------------------------------
Admittedly this concept is a bit confusing at first.
Let's do another example.
Consider a 2 by 3 rectangle of area 2*3 = 6 square units.
Now apply a linear scale factor of 4 to quadruple each side. We get a 8 by 12 rectangle of area 8*12 = 96.
Notice the jump from 6 to 96 is "times 16" (since 96/6 = 16) and it's no coincidence that 16 is 4^2, i.e. the result of squaring the linear scale factor.
new area = (area scale factor)*(old area)
new area = 16*(old area)
new area = 16*6
new area = 96
This shows that 16 is the area scale factor.

The equation that can be used to find the value of x is (2.5x+1.5)4=36, and the value of x is 3.
What is the area of a rectangle?The area of a rectangle is the product of its length and breadth. It is given by the formula,
Area of rectangle = Length × width
Given the length of the rectangle is 2.5x+1.5, while the width is 4. Also, it is mentioned in the question that the area of the rectangle is 36 square units. Therefore, we can write the area of the rectangle as,
[tex](2.5 x+1.5) \times 4 = 36\\\\(2.5 x \times 4) +(1.5\times 4) = 36\\\\10x + 6=36\\\\x = \dfrac{36-6}{10}\\\\x = 3[/tex]

I dont understand this question at all, please answer w/ explanation if you can
Answer:
The answer is C.
Step-by-step explanation:
3.844 X 10 w/ power of 5= 384400
2 X 10 w/ power of 3= 2000
2000 x 384400= 768800000
7.688 x 10 w/ power of 5 = 768800
Answer:
Jupiter to Sun = 7.688 * 10⁸km
Jupiter to Sun = 2 * 10³ times Earth to Moon
Substitute 3.844 * 10⁵km for Earth to Moon
Jupiter to Sun = 2 * 10³ * 3.844 * 10⁵km
Jupiter to Sun = 2 * 3.844 * 10³ * 10⁵km
Jupiter to Sun = 7.688 * 10³ * 10⁵km
Jupiter to Sun = 7.688 * 10⁸km
Therefore, the answer would be C. 7.688 * 10⁸km
Find the mean median mode and range for the following data 77 60 59 70 89 95
Answer:
Mean = 75
Median = 73.5
Mode = 95
Range = 36
Step-by-step explanation:
Given:
77,60,59,70,89,95Sort:
59,60,70,77,89,95To find:
MeanMedianModeRangeMean:
[tex]\displaystyle \large{\dfrac{1}{n}\sum_{i =1}^n x_i = \dfrac{x_1+x_2+x_3+...+x_n}{n}}[/tex]
Sum of all data divides by amount.
[tex]\displaystyle \large{\dfrac{59+60+70+77+89+95}{6}=\dfrac{450}{6}}\\\\\displaystyle \large{\therefore mean=75}[/tex]
Therefore, mean = 75
Median:
If it’s exact middle then that’s the median. However, if two data or values happen to be in middle:
[tex]\displaystyle \large{\dfrac{x_1+x_2}{2}}[/tex]
From 59,60,70,77,89,95, since 70 and 77 are in middle:
[tex]\displaystyle \large{\dfrac{70+77}{2} = \dfrac{147}{2}}\\\displaystyle \large{\therefore median = 73.5}[/tex]
Therefore, median = 73.5
Mode:
The highest value or/and the highest amount of data. Mode can have more than one.
From sorted data, there are no repetitive data nor same data. Consider the highest value:
Therefore, mode = 95
Range:
[tex]\displaystyle \large{x_{max}-x_{min}}[/tex] or highest value - lowest value
Thus:
[tex]\displaystyle \large{95-59 = 36}[/tex]
Therefore, range = 36

You have the proper formula. You just need to swap some things around so we aren't solving for C. C is always the hypotenuse, the diagonal line opposite the right triangle. A and B can be either side unless specified.
1. The side we're solving for can either be called a or b. Let's call it A.
2. Now, switch around the theorem to solve for a: [tex]C^2-B^2=A^2\\[/tex]
3. Plug in what we know: [tex]8^2-2^2=a^2[/tex]
4. It simplifies down to [tex]60=a^2[/tex]
5. The "[tex]a^2[/tex] " means to square the a. We need to undo that to get a by itself. The opposite of squared is the square root
6. This leaves us to take the square root of both sides, which isolates a.
7. [tex]\sqrt{60}[/tex] is the answer. It's asking for it in the square root so we don't need to simplify it.

Answer:
110 pages
Step-by-step explanation:
Let number of pages read on 1st day = x
-> No. of pages read on 2nd day = 2x
& No. of pages read on 3rd day = x - 6
Total no of pages read = 458
-> x + 2x + x - 6 = 458
-> 4x - 6 = 458
-> 4x = 458 + 6
-> 4x = 464
-> x = 464/4
-> x = 116
No of pages read on third day = x - 6 = 116 - 6 = 110

Answer:
Option A
Step-by-step explanation:
Given expression:
3x² - 10x - 8Option A
⇒ (x - 4)(3x + 2)
⇒ (x × 3x) + (2 × x) + (-4 × 3x) + (-4 × 2)
⇒ (3x²) + (2x) + (-12x) + (-8)
⇒ 3x² + 2x - 12x - 8
⇒ 3x² - 10x - 8
3x² - 10x - 8 = 3x² - 10x - 8 (Yes!)
Option B
⇒ (3x - 4)(x - 2)
⇒ (3x × x) + (3x × -2) + (-4 × x) + (-4 × -2)
⇒ (3x²) + (-6x) + (-4x) + (8)
⇒ 3x² - 6x - 4x + (8)
⇒ 3x² - 10x + 8
3x² - 10x - 8 = 3x² - 10x + 8 (No!)
Option C
⇒ (3x - 4)(x + 2)
⇒ (3x × x) + (3x × 2) + (-4 × x) + (-4 × 2)
⇒ (3x²) + (6x) + (-4x) + (-8)
⇒ 3x² + 6x - 4x - 8
⇒ 3x² + 2x - 8
3x² - 10x - 8 = 3x² + 2x - 8 (No!)
Option D
⇒ (3x - 2)(x - 4)
⇒ (3x × x) + (3x × -4) + (-2 × x) + (-2 × -4)
⇒ (3x²) + (-12x) + (-2x) + (8)
⇒ 3x² - 12x - 2x + 8
⇒ 3x² - 14x + 8
3x² - 10x - 8 = 3x² - 14x + 8 (No!)
Since the expression of option A has the same value as the given expression, option A is correct.
Answer:
Hi! Let's find which expression is equivalent to [tex]3x^{2} - 10x - 8[/tex]. First, remember that expressions are equivalent when they have identical solutions or roots. That means we have to do three things:
- solve [tex]3x^{2} - 10x - 8[/tex]
- review the listed expressions
- determine which solution is equivalent to the solution of [tex]3x^{2} - 10x - 8[/tex]
First, let's solve [tex]3x^{2} - 10x - 8[/tex].
Use the sum-product pattern -
3x^2 - 10x - 8
3x^2 + 2x - 12x - 8
Common factor from the two pairs -
3x^2 + 2x - 12x - 8
x(3x + 2) - 4(3x + 2)
Rewrite in factored form -
x(3x + 2) - 4(3x + 2)
(x - 4)(3x + 2)
Now, let's review the listed expressions. We have:
A. (x - 4)(3x + 2)
B. (3x - 4)(x - 2)
C. (3x - 4)(x + 2)
D. (3x - 2)(x + 4)
We're looking for one of these expressions to be equivalent to the solution of [tex]3x^{2} - 10x - 8[/tex], which we know is (x - 4)(3x + 2). The first choice, A. (x - 4)(3x + 2), would be our answer!

"The slope of the linear regression line can be calculated using any two points in the data."
The statement "The slope of the linear regression line can be calculated using any two points in the data." is always true for any two points.
What is regression line?Linear regression shows the relationship between two variables by fitting a linear equation to observed data. One variable is considered to be an explanatory variable, and the other is considered to be a dependent variable.
A linear regression line has an equation of the form Y = a + bX, where X is the explanatory variable and Y is the dependent variable.
Firstly, as per difinition the equation of linear regression line is
y= a + bx, where b is the slope of the line and a is intercept .
The formula to calculate the slope of the line be,
[tex]b=\frac{n(\sum xy)-(\sum x)(\sum y)}{n(\sum x^{2}) - (\sum x)^2 }[/tex]
here n represent the number of data given in a question, x and y are the two points.
If we look at the formula with point x and y the slope can't be calculated.
Also, the equation of linear regression line , y= a+ bx also contain two points (x, y).
As per the discussion it is not possible to calculate the slope of linear regression line without two points.

a sphere has a volume of 179.6 cubic cm which value is closest to the radius of this sphere in cm
The volume of the sphere is the amount of space in it, and the value closest to the radius is 3.5 cm
How to determine the radius of the sphere?The volume is given as:
V = 179.6
The volume is calculated using:
V = 4/3πr³
So, we have:
4/3πr³ = 179.6
Multiply both sides by 3/4
πr³ = 134/7
Divide both sides by π
r³ = 42.88
Take the cube root of both sides
r = 3.5
Hence, the value closest to the radius is 3.5 cm
