Answer:
20,000 per sq. km.
Step-by-step explanation:
In this question, the variable k represents the total number of people in a single square km. Since we are provided both the total number of the population and the total square kilometers of the land, we can calculate the value of k by dividing the population size by the total land. Therefore, the calculation would be the following...
[tex]\frac{10,400,000 people}{520km^{2} }[/tex] = k
20,000 per sq. km. = k
Finally, we can see that the value of k is 20,000 per sq. km.

Do you also want an explanation?
Answer:
7 10 13 16
Step-by-step explanation:
a1 = 4
a6 = 19
n = 6
d = ?
a6 = a1 + (n - 1)d
19 = 4 + (6 - 1)*d
19 - 4 = 5*d
15 = 5d
d = 15/5
d = 3

Find the exact circumference if the circle has a radius of 12 cm
==========================================================
Explanation:
If the circumference is r = 12 cm, then the diameter is double that at d = 2*r = 2*12 = 24 cm.
This then leads to the circumference of C = pi*d = pi*24 = 24pi
This is exact in terms of pi. Replace pi with something like 3.14 to find its approximate value. The circumference is the distance around the circle's edge, aka perimeter.

You just hung a picture twelve inches above the wall trim. Your friend thinks the
picture looks crooked. Use what you know about parallel lines and transversals to
determine if the picture is level.
Step 1: You don't have a level, but you are in luck. You know the wall trim is level.
You have a protractor and the sun is casting a shadow on the wall. Describe how
you can determine if the picture is level.
: Assume you measured ∠3 and ∠5 and found them to be equal. Use the
spaces provided below to complete a formal proof that demonstrates the picture
is level with the trim.
Answer:
The angles measured between the shadow and the wall trim and the shadow and the top or bottom of the picture should be equal if the picture is level
Step-by-step explanation:
Whereby the picture is 12 inches above the wall trim and the Sun is casting a shadow on the wall, therefore, the edges of the shadow of a straight edged object is straight
If the picture is level, the shadow cast by the sun is transversal to the wall trim and the line formed by extending the bottom or top of the picture in the direction of the shadow. That is, if the picture is parallel, the shadow cast by the Sun on the wall is transversal to the picture and the wall trim if or when the shadow eventually crosses the picture
With the protractor, the angle between the shadow and the wall trim and the shadow and the top or bottom is measured
The angles measured should be the same if the picture is level.

What is the final transformation in the composition of transformations that maps pre-image GHJK to image G'H"J"K"?
a translation to the right
a reflection across line m
a 90° rotation about point G
a 180° rotation about point G
Answer:
a reflection across line m
Step-by-step explanation:
A reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K". Option B is correct.
What is reflection?Reflection is defined in an atmosphere as when the beam of light or wave strikes to the plane or curved surface deviates back from the atmosphere.
The final transformation is to determine that transition states have been shown in the image that describes how pre-image GHJK transformed to image G'H"J"K".
Steps of Transformation
Pre-image GHJK first rotates anticlockwise by an angle of 90° to G'H'J'K'.
Then G'H'J'K' reflected across the line m to G'H"J"K". It is the final transition state.
Thus, a reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K".

every parallelogram is a square?
every rectangle with four congruent sides is a square?
every rectangle is a quadrilateral?
every quadrilateral is a rectangle?
Answer:
every parallelogram is a square? False
every rectangle with four congruent sides is a square? True
every rectangle is a quadrilateral? True
every quadrilateral is a rectangle? False
Step-by-step explanation:
every parallelogram is a square?
A parallelogram has two opposite pairs of parallel lines and opposite congruent sides. A square needs to have 4 right angles and all sides need to be equal. In the restrictions of a parallelogram, these cannot be concluded, therefore parallelogram are not always squares.
every rectangle with four congruent sides is a square?
Square require 4 congruent sides and 4 right angles. Rectangles already have 4 right angles. If you add 4 congruent sides to the mix, it means that these rectangles are always squares.
every rectangle is a quadrilateral?
A quadrilateral is defined by a shape having 4 sides. Rectangles have 4 sides, so they fit into the category of quadrilaterals.
every quadrilateral is a rectangle?
A quadrilateral is a just a shape with four sides. We do not know if it has 4 right angles, so not every quadrilateral is a rectangle.

Answer:
64 × pi m²
Step-by-step explanation:
the formulas needed for the surface area of a cone are :
base area plus the "mantle", the lateral "wall" around it.
the base area is a circle.
so, that formula is Ac = pi×r²
the "wall" formula is Aw = pi×r×s
r = radius
s = slant height = 12
the formula for the surface area of a sphere is
As = 4×pi×r²
we know now, that both surface areas are the same, and also the radius is the same for both objects.
Ac + Aw = As
pi×r² + 12×pi×r = 4×pi×r²
=>
12×pi×r = 3×pi×r²
12×pi = 3×pi×r
12 = 3×r
r = 4 m
now, we only need to use this value of r in our formulas for surface areas, like for the sphere :
4×pi×r² = 4×pi×4² = 4³×pi = 64×pi

What is an equation of the line that passes through the point (-5,-2)and is parallel to the line x-y=5?
Answer:
[tex]y=x+3[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Parallel lines always have the same slope (m)1) Determine the slope (m)
[tex]x-y=5[/tex]
Rearrange this given equation into slope-intercept form. This will make it easier for us to identify the slope.
Subtract x from both sides of the equation
[tex]x-y-x=-x+5\\-y=-x+5[/tex]
Divide both sides by -1 to isolate y
[tex]y=x-5[/tex]
Now, we can identify clearly that the slope of this line is 1. Because parallel lines have the same slopes, a line parallel to this one would also have a slope of 1. Plug this into [tex]y=mx+b[/tex]:
[tex]y=1x+b\\y=x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=x+b[/tex]
Plug in the given point (-5,-2)
[tex]-2=-5+b[/tex]
Add 5 to both sides
[tex]-2+5=-5+b+5\\3=b[/tex]
Therefore, the y-intercept of the line is 3. Plug this back into [tex]y=x+b[/tex]:
[tex]y=x+3[/tex]

975 toffees are to be distributed among 23 children. Estimate the numbers of toffees that each child will get in nearest tens.
Answer:
40
Step-by-step explanation:
Total number of toffees = 975
Total number of children = 23
Estimate the numbers of toffees that each child will get in nearest tens.
Number of toffees each child get = Total number of toffees / Total number of children
= 975 / 23
= 42.391304347826
Approximately,
Number of toffees each child get = 40 to the nearest tens

both physical and mental labour are important in the development of Civilization express in 300 words
Answer:
Civilization refers to a well-organized and highly cultural urban society. Urban living is based on people's freedom of self-realization, specialization and a self-organizing market economy. It has also been defined as a society where agriculture and handicrafts have developed, social strata have developed, cities and the state have emerged, writing is known and high-quality literary and artistic works are created.
The first civilizations emerged in the region of Mesopotamia, approximately 6000 years ago. For the development of these it was eminently necessary that individuals had developed cognitive and physical capacities that allowed them a correct cultural assimilation with respect to their peers, and also a correct relationship between them without the development of conflicts.
In addition, a large amount of physical and mental work was required for the development of the organization of these civilizations, both at the infrastructure level and their ideological development.
