Answer: 17,857 people/sq mile
Step-by-step explanation:
Tokyo, Japan: 38,000,000 people ÷ 845 sq miles = 44,970 people/sq mile
Delhi, India: 36,000,000 people ÷ 573 sq miles = 62,827 people/sq mile
62,827 - 44,970 = 17,857
find the value of x so that BC II DE
Answer:
x = 10
Step-by-step explanation:
if BC and DE are parallel then the sides of the triangle are divided proportionally, that is
\(\frac{CE}{AE}\) = \(\frac{BD}{AD}\) ( substitute values )
\(\frac{x-2}{16}\) = \(\frac{x-3}{14}\) ( cross- multiply )
16(x - 3) = 14(x - 2) ← distribute parenthesis
16x - 48 = 14x - 28 ( subtract 14x from both sides )
2x - 48 = - 28 ( add 48 to both sides )
2x = 20 ( divide both sides by 2 )
x = 10
then for BC and DE to be parallel, x has the value x = 10

The similar triangles for this problem are given as follows:
RST and VUT.
Then the measure VT is given as follows:
VT = 5.4 units.
What are similar triangles?Similar triangles are triangles that share these two features listed as follows:
Congruent angle measures, as both triangles have the same angle measures.Proportional side lengths, which helps us find the missing side lengths.Hence the similar triangles for this problem are given as follows:
RST and VUT.
The proportional relationship for the side lengths is given as follows:
6/14 = (x + 2)/(4x - 1).
Applying cross multiplication, the value of x is obtained as follows:
14(x + 2) = 6(4x - 1)
14x + 28 = 24x - 6
10x = 3.4
x = 3.4.
Then the length VT is given as follows:
VT = 3.4 + 2
VT = 5.4 units.

Please help me and ty :)
Answer:
$60
Step-by-step explanation:
In a set of data, the median is the value that is placed in the middle. to find the median, we must order the numbers from least to greatest, like so:
20, 40, 40, 50, 60, 60, 60, 60, 70, 70
Using this representation, we find that there are two numbers in the middle: 60 and 60 (since the amount of data is an even number, there will be two numbers in the center).
When something like this occurs, find the average of the two numbers in the middle (and the values and divide by the number of values). We have:
60 + 60 = 120;
\(\frac{120}{2} = 60\)
Therefore, the median is $60.

5.Given the functions f(x)=-2x + 4 and g(x) = 2x- 8, find the value of x for which f(x) = g(x).
6.Graph the function
Based on the definition of the functions, the value of x if f(x) = g(x) is 3
How to determine the value of x?The equations of the functions are given as
f(x) = -2x + 4
g(x) = 2x - 8
It should be noted that the above equations are linear equations
From the question, we understand that the functions are equal
This means that, we have the following equation
f(x) = g(x)
Substitute the known values in the above equation
So, we have the following equation
-2x + 4 = 2x - 8
Collect the like terms in the above equation
So, we have
2x + 2x = 8 + 4
Evaluate the like terms in the above equation
So, we have
4x = 12
Divide both sides by 4
x = 3
Hence, the value of x such that the equations are equal is 3

m=7/3 through (-5,8))
pls help fast ‼️
Answer:
Step-by-step explanation:
Well you have 1/2 the answer.
m = 7/3
y = mx + b
y = 7/3 * x + b
Use the point to to determine b
x = -5
y = 8
8 = 7/3 * (-5) + b
8 = -35/3 + b Add 35/3 to both sides
8 + 35/3 = b
19 2/3 = b
So the complete answer is
y = 7/3 x + 19 2/3

The definition of the absolute value of a number is its magnitude, or distance, from zero. How do these two definitions connect?
The way that the definitions of the absolute value of a number, connect is that the absolute value of a number is the positive representation of the number's distance from zero.
What is absolute value ?The absolute value of a number is the numerical value of a real number without regard to its sign. In other words, the absolute value of a number is the number's distance from zero on the number line. The absolute value of a number is always positive or zero, and is written as the number inside of absolute value notation, which is two vertical lines on either side of the number, like so: |number|. For example, the absolute value of -5 is 5, and the absolute value of 5 is also 5.
The distance from zero is the same as the magnitude of a number, and the absolute value of a number is a non-negative representation of its magnitude. So, in other words, the absolute value of a number is its distance from zero on the number line. The two definitions are connected because the absolute value of a number is a positive representation of its distance from zero.

Find x in the diagram below
The value of the angle x is 30 degrees
How to determine the valueTo determine the value of the variable x, we need to know the triangle sum theorem.
The triangle sum theorem is a theorem in mathematics stating that the sum total of the interior angles in a triangle is equivalent to 180 degrees.
We should also note that angle at right angle is 90 degrees
Then, we have the angles written as;
90 degrees
2x degrees
x degrees
Equate the angles , we have;
2x + x + 90 = 180
collect the like terms, we have;
2x + x = 180 - 90
add or subtract the like terms, we have;
3x = 90
divide by the coefficient
x = 30

#3 Preimage point B is
located at (5,-4).
B' is located at (20, -16).
Write the algebraic rule for
the transformation.
The algebraic rule for the transformation is B' = (Bx + 15, By - 12)
Given data ,
To determine the algebraic rule for the transformation from point B to point B', we need to find the equations that relate the coordinates of the preimage point B to the image point B'.
Let's denote the translation amounts in the x-direction and y-direction as (dx, dy). The coordinates of B' can be obtained by adding these translation amounts to the coordinates of B:
B' = (Bx + dx, By + dy)
Given that B is located at (5, -4) and B' is located at (20, -16), we can calculate the translation amounts:
dx = 20 - 5 = 15
dy = -16 - (-4) = -12
Hence , the algebraic rule for the transformation is B' = (Bx + 15, By - 12)

Answer:
3. yes: a[1] = -8, a[n] = a[n-1] +7; an = -8 +7(n -1)
4. no (no common difference)
Step-by-step explanation:
An arithmetic sequence is one in which each term has the same difference from the term before it.
__
3. -1 -(-8) = 7; 6 -(-1) = 7; 13 -6 - 7. The differences are all 7, so the terms have a common difference. This sequence is arithmetic.
The general form of the recursive rule for an arithmetic sequence with first term a1 and common difference d is ...
a[1] = a1; a[n] = a[n-1] +d . . . . . recursive rule
a[1] = -8; a[n] = a[n-1] +7
The general form of the explicit rule for an arithmetic sequence is ...
an = a1 +d(n -1)
an = -8 +7(n -1)

4. The differences are ...
8 -1 = 7; 27 -8 = 19; 81 -27 = 54 . . . the differences are not common
This sequences is not arithmetic.
Which of the following is the fourth vertex needed to create a rectangle with vertices located at (−15, 3), (−15, −6), and (25, −6)?
(−6, 25)
(−25, −3)
(6, −25)
(25, 3)
The missing fourth vertex needed to create a rectangle is (25, 3) option D.
Define the term vertices?Vertices (singular: vertex) are the corners or points where two or more lines, edges, or curves intersect and form an angle.
Here, the width of one side of the rectangle;
⇒ +3 - (-6) = 9 unit (left side y-coordinates)
Similarly the length of the rectangle;
⇒ 25 - (-15) = 40 unit (up-side x-coordinates)
Since a rectangular shape has two sets of equal sides of equivalent width (y-coordinates) and length (x-coordinates), we realize that the missing fourth vertex should be 9 units and 40 units over the point (25, -6). and (-15, 3)
So, we add 9 to the y-coordinate of (25, -6) and add 40 to the x-coordinate of (-15, 3) to get the missing vertex:
⇒ (25, -6+9) = (25, 3)
⇒ (-15+40, 3) = (25, 3)
Therefore, the missing fourth vertex is (25, 3)
