Answer:
Faction of population = 1.39 / 7.2
Percentage of population = 19.3% (Approx.)
Step-by-step explanation:
Given:
China's population in 2014 = 1.39 billion (Approximately)
Find:
Compare China's population to world population
Computation:
World's population in 2014 = 7.2 billion (Approximately)
Faction of population = China's population in 2014 / World's population in 2014
Faction of population = 1.39 / 7.2
Percentage of population = [China's population in 2014 / World's population in 2014]100
Percentage of population = [1.39/7.2]100
Percentage of population = [0.193]100
Percentage of population = 19.3% (Approx.)

A homeowner puts a patio in the northwest corner of a square backyard. The area of the patios is 750
square feet. What is the area of the backyard?
120 ft
X
25
xft
Answer:
17.6621ft²
Step-by-step explanation:
First we need to find the side length of the patio x
SInce the area of the patio = 750
Area of patio = x * x
Area of patio = x²
750 = x²
Swap
x² = 750
x = √750
x = 27.39ft
Length of the backyard = 27.39ft - 25ft = 2.39ft
Width of the backyard = 27.39ft - 20ft = 7.39ft
Area of the backyard = 2.39 * 7.39
Area of the backyard = 17.6621ft²
The dimension of the backyard is 7.4 feet by 2.4 feet. Then the area of the backyard is 17.76 square feet.

A homeowner puts a patio in the northwest corner of a square backyard. The area of the patios is 750 square feet.
The dimension of the patio will be
x² = area
x² = 750
x = 27.4 feet
The dimension of the backyard will be
Length = 27.4 – 20 = 7.4
Width = 27.4 – 25 = 2.4
The area of the backyard will be
Area of backyard = 7.4 × 2.4
Area of backyard = 17.76

Which of the objects shown above are pyramids?
A. A and B
B. A and D
C. C only
D. A only
Explanation:
Both figures shown in A and B are triangular pyramids. The base is a triangle, and the lateral sides are also triangles. Another example would be rectangular pyramids where the base is a rectangle, and the lateral sides are triangles.
Choice C is ruled out because cones aren't considered pyramids.
Choice D is a combination of a rectangular prism, and a rectangular pyramid stacked on top, so it's not purely a pyramid only. We can rule out choice D.

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".

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]

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.
Ab is tangent to circle o at a. the diagram is not drawn to scale. if ao =30 and bc = 48 what is ab?
a) 84
b) 78
c) 76
d) 72
Answer:
91.19
Step-by-step explanation:
From the given diagram;
BO = 2 BC
BO = 2(48)
BO = 96
To get AB, we will use the pythagoras theroem;
BO² = AB² + AO²
96² = AB² + 30²
9216 = AB² + 900
AB² = 9216 - 900
AB² = 8,316
AB = √8,316
AB = 91.19
Hence the length of AB is 91.19
What is the equation of the line that has a slope of -2 and passes through the point (-1, 2)?
Answer:
[tex]{ \bf{y = mx + c}} \\ 2 = ( - 2 \times - 1) + c \\ c = 0 \\ \\ { \boxed{ \bf{y = - 2x}}}[/tex]
Answer:
y = -2x
Step-by-step explanation:
The equation of a line in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -2x +b
Using the point
2 = -2(-1)+b
2 = 2+b
Add -2 to each side
2-2 =b
0=b
y = -2x+0
y = -2x
Malina has to bowl four games in her league. She bowled a 149, 162, and a 152 in her first three games. She wants to have an average score of 154. What score does she need in her fourth game?
153
152
155
154
A is right correct lol
Answer:
She needs 153
Step-by-step explanation:
Let x be the score in the 4th game
To find the average add up the scores and divide by the number of scores added
(149+162+152+x) /4 = 154
Multiply each side by 4
(149+162+152+x) /4 *4= 154*4
(149+162+152+x) = 616
Combine like terms
x+463=616
Subtract 463 from each side
x+463-463 = 616-465
x = 153
