A four-dimensional space or 4D space is a mathematical extension of the concept of three-dimensional or 3D space. Three-dimensional space is the simplest possible generalization of the observation that only three numbers, called dimensions, are needed to describe the size or position of objects in the everyday world. For example, the volume of a rectangular box is found by measuring its length (usually labeled x), width (y), and depth (z).

The area of the base of a right square pyramid is multiplied by 5, but the height is unchanged. What is the volume of the new pyramid divided by the volume of the original pyramid?
9514 1404 393
Answer:
5
Step-by-step explanation:
The volume of a right square pyramid is given by the formula ...
V = 1/3Bh
where B is the area of the base.
The volume of the larger pyramid will be ...
V' = 1/3(5B)h
So, the ratio of volumes is ...
V'/V = (1/3(5B)h)/(1/3Bh)
V'/V = 5
The ratio of volumes is 5.

Which sentence correctly compares the two points shown on the number line? -1 > 0.25 , -1 < -0.25, -0.25 < -1
Answer:
-1 < -0.25
Step-by-step explanation:
-1 is less than -0.25
less than symbol = <

Answer:
6 2/3 = x
Step-by-step explanation:
24 1/14 + 8 3/7 = (x ÷ 1 1/9) * 5 5/12
Add on the left by getting a common denominator
24 1/14 + 8 3/7*2/2 = (x ÷ 1 1/9) * 5 5/12
24 1/14 + 8 6/14 = (x ÷ 1 1/9) * 5 5/12
32 7/14 = (x ÷ 1 1/9) * 5 5/12
32 1/2 = (x ÷ 1 1/9) * 5 5/12
Changing to improper fractions
(2*32+1)/2 = (x ÷ 10/9) * (12*5+12)/12
65/2 = (x ÷ 10/9) * (65)/12
Multiply each side by 12/65
65/2 * 12/65 = (x ÷ 10/9) * (65)/12*12/65
6 = (x ÷ 10/9)
Copy dot flip
6 = x * 9/10
Multiply by 10 /9
6 * 10/9 = x * 9/10 * 10/9
60/9 =x
20/3 =x
Changing back to a mixed number

3.3 + 10m = 7.81 find the value of m ill give brainliest
Answer:
m = .451
Step-by-step explanation:
3.3 + 10m = 7.81
Subtract 3.3 from each side
3.3-3.3 + 10m = 7.81-3.3
10 m =4.51
Divide each side by 10
10m/10 = 4.51/10
m = .451
Answer:
0.451
Step-by-step explanation:
3.3+10m=7.81
10m = 7.81-3.3
10m = 4.51
m = 4.51/10
m = 0.451

What is the volume of the composite figure shown? Use 3.14 for π.
Answer:
25.12
Step-by-step explanation:
the formula of a cone is pi r^2 * h/3
r = radius and h = height
the radius is 2 and the height is 3
and the question says use 3.14 instead of pi so
we have
3.14 * 2^2 * 6/3
2*2 or 2^2 = 4
3.14 * 4 * 6/3
6/3 = 2
3.14 * 4 * 2
4*2 = 8
and 8 * 3.14 is 25.12
the width w of a rectangular swimming pool is x+5 the area a of the pool is x^2+4-5
what is an expression for the length of the pool? step by step
Answer:
x-1
Step-by-step explanation:
Area= x^2+4x-5
Width= x+5
Area= Length*breadth
x^2+4x-5=length*x+5
Length=x^2+4x-5/x+5
Therefore, length= x-1
Answer:
x-1

Answer:
700 cubic inches
Step-by-step explanation:
The question asks for how much volume the box can hold. We multiply the length (14), width (10), and height (5) to get the volume. 14 · 10 · 5 = 700.
The box can hold 700 cubic inches.

A book store is keeping track of the price of books according to the number of pages. Which scatterplot represents that bivariate data? A graph has price (dollars) on the x-axis and pages on the y-axis. A graph has books on the x-axis and pages on the y-axis. A graph has pages on the x-axis and price (dollars) on the y-axis. A graph has books on the x-axis and price on the y-axis.
Answer:
The graph has pages on the X-axis and price (dollars) on the Y-axis
Step-by-step explanation:
The X-axis will always have the independent variable (pages), while the Y-axis will have the dependent variable (number of pages). The pages will exist no matter how many there are, but the price is influenced by the number of pages.
