The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠D is 126° so option (D) is correct.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are 3 sides and three angles in every triangle, some of which may be the same.
It is known that the sum of all three angles inside a triangle will be 180°.
So, m∠D + m∠E + m∠F = 180°
(3x + 27) + (4x + 22) + 68 = 180
7x + 49 + 68 = 180
7x = 63
x = 9
So, m∠D = (3(9) + 27)° = 54°.
The exterior angle of D = 180- 54 = 126°.
Hence "The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠D is 126°".

2) So, we can write out the following:
[tex]\begin{gathered} f(x)=x \\ f(9)=-8 \\ \\ f(x-2)=x \\ f(9-2)=-8 \\ f(7)=-8 \end{gathered}[/tex]Note that a horizontal translation just "pushes to the right". So there was no vertical shift.

You visit your favorite restaurant and order an appetizer for $5.99, a drink for $4.50, your meal for $10.99, and dessert for $3.75. The sales tax is 9%. and you
would like to leave an 18% tip. Find the total cost of your meal.
Using percentages, we can conclude that the total cost of the meal is approximately $33.
What is the percentage?A percentage is a number or ratio expressed as a fraction of 100 in mathematics. Frequently, it is indicated by the percent sign, "%".By dividing the value by the total value and multiplying the result by 100, one can determine the percentage. The percentage calculation formula is (value/total value)100%.So, the total cost of the meal:
$5.99 + $4.50 + $10.99 + $3.75 = $25.23Sales tax on the bill: 9%
25.23/100 × 9 = $2.2977Total bill printed on bill: $25.23 + $2.2977 = $27.527718% tip of the bill:
27.5277/100 × 18 = 4.954986Rounding off: $5Total cost of meal: $27.5277 + $5 = $32.5277
Rounding off: $33Therefore, using percentages, we can conclude that the total cost of the meal is approximately $33.

What is distance?
Distance is the total movement of an object without any regard to direction
Given data
vertex 1 is at ( -4, - 1)
vertex 2 is at ( - 4, 5)
vertex 3 is at (2,5)
vertex 4 is at ( 2, -1 )
Lindseys jogs along the edge of the park in order from vertex 1 to the vertex 2 , vertex 2 to vertex 3 and vertex 3 to vertex 4 and then back to vertex 1. One unit in the coordinate grid is 20 yards.
Let us calculate distance vertex 1 and vertex 2of (-4,-1) and (-4,5)
x₁=-4,x₂=-4, y₂=5, y₁=-1
Distance=√(x₂-x₁)²+(y₂-y₁)²
Substitute the values x₁=-4,x₂=-4, y₂=5, y₁=-1 in distance formula
=√(-4+4)²+(5-(-1))²
=√6²
=6
Since 1 one unit on the coordinate gride equal 20 yd.
so 6×20=120 yards.
Now for four vertices we get 4×120=480 yards.

Function ggg can be thought of as a translated (shifted) version of f(x)=x^2f(x)=x

f, left parenthesis, x, right parenthesis, equals, x, squared.
A parabola labeled f has a vertex at the point 0, 0. A parabola labeled g has a vertex at the point negative 4, negative 5.
Write the equation for g(x)g(x
The equation for g(x) is g(x) = x²-3
When x=0, f(x)= 0 and so has a vertex at (0,0)
Given that g(x) is a shifter version of f(x) and has a vertex at (0,-3), g(x) must be shifted down the y axis such that g(x)= x2+c when x=0 and g(x)= -3 -3=0+c c=-3 when x=3.

A flying carpet flies 2.4 miles with the wind in the same amount of time it flies 1.4 miles against the wind. The wind speed is 4 mph what is the speed of the flying carpet
The most appropriate choice for speed will be given by-
Speed of the flying carpet is 15.2 mph
What is speed?
The distance travelled by the body per unit time is called speed of the body.
If d is the distance travelled by the body and t is the time taken, then
speed = [tex]\frac{d}{t}[/tex]
Speed is a scalar quantity as the direction is not taken into account.
Here,
Let the speed of the flying carpet be [tex]x[/tex] miles
A flying carpet flies 2.4 miles with the wind
Time taken flying with the wind = [tex]\frac{2.4}{x +4}[/tex]
The flying carpet flies 1.4 miles against the wind
Time taken flying against the wind = [tex]\frac{1.4}{x - 4}[/tex]
By the problem,
[tex]\frac{2.4}{x +4} = \frac{1.4}{x-4}[/tex]
[tex]2.4(x - 4) = 1.4(x + 4)\\2.4 x - 9.6 = 1.4 x + 5.6\\2.4 x - 1.4 x = 9.6 + 5.6\\[/tex]

The average age of 6men is 35years and the average age of 4 of them is 32years. Find the age of the remaining 2 men if one is 3years older than the other
The age for two men is 39.5 and 42.5.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them. Variables are the name given to these symbols because they lack set values. We frequently observe constant change in specific variables in our day-to-day situations. But the need to depict these shifting values is ongoing. These values are frequently represented in algebra by symbols such as x, y, z, p, or q, and these symbols are known as variables.
Given:
Average of 6 men = 35
Average of 4 men = 32
So, Total age of 6 men
=6x35
=210 years
and, Total age of 4 men
=32 x 4
=128 years
Then, the remaining age for 2 people
= 210 - 128
=82 years
Let the age for two be x and y
then , x+ y=82
and x-y=3
On solving
2x =85
x=42.5 years
and y=39.5 years
Hence, the age for two men is 39.5 and 42.5.

The circle graph shows how the annual budget for a company is divided by department.

Observe the given graph carefully.
In a circle graph, the circle is divided into different sectors, each characterized by its central angle.
The complete circle measures 360 degrees. So the complete distribution (100% data) corresponds to 360 degrees.
In the given problem, we are concerned with the budget,
[tex]360^{\circ}=100\text{ percent budget}[/tex](a)
Consider the following,
[tex]\begin{gathered} \text{ Total budget}=360^{\circ} \\ \frac{1}{4}\times\text{ Total budget}=\frac{1}{4}\times360^{\circ}=90^{\circ} \end{gathered}[/tex]So, one-fourth of the budget will correspond to the department which covers the 90-degree sector of the circle graph.
As observed from the graph, the most suitable department under this criteria is the Engineering Department.
Thus, Engineering Department gets approximately one-fourth of the annual budget.
(b)
Consider that the departments Engineering and support combiningly cover a little more than one-third of the area of complete circle.
Consider the following,
[tex]\begin{gathered} 360^{\circ}=100\text{ percent} \\ 120^{\circ}=\frac{120}{360}\times100=33.33\text{ percent} \end{gathered}[/tex]Note that the area covered by the department is a little more than one-third, so the corresponding percentage value must also be a little more than 33.33%.
From the available options, 40% is the value available next to 33.33%, so this should be the most suitable choice.
Thus, it can be concluded that approximately 40% of the annual budget goes to the departments Engineering and Support combined.
Therefore, option (b) is the correct choice.

x - 3y = -3 can be written as:
x = -3 + 3y ____(3)
Putting in (2) we get,

x = 3 and y = 2
Putting in the equation it is satisfied.
x - 3y = -3
3 - 3 x 2 = -3

-3 = -3
4x + 3y = 18
4x3 + 3x2 = 18

Given the sequence:
C. 3, 12, 27, 48, 75
First, we need to calculate the difference between terms:
12-3 = 9 27-12 = 15 48-27 = 21 75 - 28 = 27
Arithmetic relationship: 9, 15 , 21, 27
To obtain the sequence we use the following formula:

15-9 = 6 21-25 = 6 27 - 21 = 6
