Answer:
68°
Step-by-step explanation:
a triangle hold 180° so 180-43=137 and G and H are almost the same value where G is 69° and H is 68°
Step-by-step explanation:
x°+43°+(x-1)°=180°(sum of all the interior angle of triangle is 180°
2x°+42°=180°
2x°=180°-42°
2x°=138°
x=138°/2°
:. x=69°
Now,
angle H= (x-1)°=69°-1°=68°
:. angle H= 68°

Which compound inequality is represented by the graph?
-5 4 -3 -2 -1 0 1 2 3 4 5
Answers
Answer: x < -2 or x ≥ 4.
Step-by-step explanation:
In the graph, we can see that our set of numbers includes:
All the numbers larger than 4, and the 4 itself (because we have a colored dot in the 4)
Then this range of values can be represented with:
x ≥ 4.
(because this allows x to be larger than 4, or equal than 4)
Our set also includes all the numbers smaller than -2, where the -2 is not included because we have a white dot in the -2.
This can be represented as:
x < -2
Then our set can be described with:
x < -2 or x ≥ 4.

Answers
Answer:
2
Step-by-step explanation:
First calculate the mean. This is done by adding the numbers and dividing by the count:
sum = 6+0+4+3+2 = 15
count = 5
mean = 15/5 = 3
Now create a table with the "squared deviation to the mean":
6: (6 - 3)² = 9
0: (0 - 3)² = 9
4: (4 - 3)² = 1
3: (3 - 3)² = 0
2: (2 - 3)² = 1
And sum these:
9+9+1+0+1 = 20
Divide by the count to find σ²:
σ² = 20/5 = 4
Hence σ = √4 = 2

----------
148 | 13 03

-----------
78^2 = 6084.
We observe that 78^2 < 6203.
79^2 = 6241.
We observe that 79^2 > 6203.
Hence the number to be added to 6203 is 6241 - 6203 = 38.
6203 + 38 = 3241
= 79 * 79
= 79.
Therefore 38 should be added to 6203 to obtain a perfect square.

Work Shown:
Break the figure up as shown by the dashed lines. Think of cutting along those lines to form 3 separate figures. The trapezoid on the left has area
A = h*(b1+b2)/2
A = 5*(11+12)/2
A = 57.5
The rectangle in the middle has area
A = L*W
A = 12*15
A = 180
The trapezoid on the right has area
A = h*(b1+b2)/2
A = 10*(12+9)/2
A = 105
Overall, the entire figure has area of 57.5+180+105 = 342.5 square meters
1 can costs £6 and it covers 15 square meters. We need to cover 342.5 square meters
342.5/15 = 22.8333333333333 approximately
Round up to the nearest whole number to get 23
We need 23 cans to be able to paint 342.5 square meters or more
Note that 22 cans won't be enough because 22*15 = 330 is short of 342.5
While 23 cans is more than enough since 23*15 = 345. It's better to have leftovers than come up short.
Since each can costs £6 and we need 23 of them, the total cost would then come to 6*23 = 138 pounds
Answer:
The figure consists of two trapeziums and a rectangle
Area of figure = Area of rectangle + Area of the two trapeziums
Area of rectangle = length × width
= 12m × 15m = 180m²
Area of first trapezium = 1/2(a+b) × height
= 1/2(12+11)×5
= 57.5m²
Area of second trapezium = 1/2(a+b) × height
= 1/2(9+12)×10
= 105m²
Area of figure = 180 + 57.5 + 105 = 342.5m²
If 15m² = 6£
342.5 = 342.5/15 ×6
= £ 137

Answer:
Option (1)
Step-by-step explanation:
As we know, sum of an infinite geometric series,
[tex]S=\frac{a}{1-r}[/tex]
Here a = first term of the series
and r = common ratio.
If |r| < 1 Series converges
If |r| ≥ 1 Series diverges
For Option (1),
S = 262 + 301.3 + 346.5.........
Common ratio = [tex]\frac{301.3}{4.2}[/tex] = 1.15
Since |r| = 1.15 > 1
Series will diverge
Option (2),
S = 4.2 + 3.57 + 3.0345..........
Common ratio = [tex]\frac{3.57}{4.2}[/tex] = 0.85
Since |r| < 1
Series will converge.
Option (3),
S = 6651 + 729 + 81........
Common ratio = [tex]\frac{729}{6651}[/tex] = 0.11
Since |r| < 1
Series will converge.
Option (4),
S = 100, 50, 25...........
Common ratio = [tex]\frac{50}{100}=\frac{1}{2}[/tex]
Since |r| < 1
Series will converge.

a solid cuboid is made from centimeter cubes how many centimeter cubes were used to make the cuboid
Answers
This question is incomplete because it lacks the appropriate diagram.
Please find attached this answer the appropriate diagram.
Kindly note that: The diagram was obtained from or referenced from Planes and Elevation (F) Version 3 January 2016.
Answer:
72 centimeter cubes
Step-by-step explanation:
Looking at the attached diagram, we are given 3 views of the cuboid
a) The plan view: The is the view of the cuboid from the top or a very high position
b) Front Elevation view: This is the view of the cuboid from the front
c) Side elevation view: This is the view of the cuboid from the side.
In the referenced and attached diagram,
The plan view shows us the top of the cuboid with a length of 4 and breadth of 6
The front elevation view shows us the front of the cuboid with a length of 3 and breadth of 4
The side elevation view shows us the side of the cuboid with a length is 3 and breadth of 6
We are told to find the number of centimeter cubes were used to make the cuboid. This means we are to find the volume of the cuboid.
Volume of a cuboid = Length × Width × Height
Combining the 3 views together,
The Length of the cuboid = 4
Width of the cuboid = 6
Height of the cuboid = 3
Volume of the cuboid = 4 × 6 × 3
= 72
Therefore, the number of centimeter cubes that were used to make the cuboid is 72.

what is the distance between ( -3, -4) and ( 6, -4) on the coordinate plane
Answers
Answer:
The distance between (-3, -4) and (6, -4) is 9 units.
Step-by-step explanation:
First, we must know the distance formula between two points.
[tex]Distance(d)=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We will use (-3, -4) for (x₁, y₁) and we will use (6, -4) for (x₂, y₂).
[tex]Distance=\sqrt{(6-(-3)^2+(-4-(-4))^2)}[/tex]
[tex]Distance=\sqrt{(9)^2+(0)^2}[/tex]
[tex]Distance=\sqrt{81+0}[/tex]
[tex]Distance=9[/tex]
So, the distance between the two points is 9 units.

What are factors of production?
" Factors of production are resources that are the building blocks of the economy; they are what people use to produce goods and services. Economists divide the factors of production into four categories: land, labor, capital, and entrepreneurship."
What are some examples of entrepreneurship as a factor of production?
An entrepreneur is a person who combines the other factors of production - land, labor, and capital - to earn a profit. The most successful entrepreneurs are innovators who find new ways to produce goods and services or who develop new goods and services to bring to market. Without the entrepreneur combining land, labor, and capital in new ways, many of the innovations we see around us would not exist. Entrepreneurs are a vital engine of economic growth helping to build some of the largest firms in the world as well as some of the small businesses in your neighborhood. Entrepreneurs thrive in economies where they have the freedom to start businesses and buy resources freely.
