Estimate the area and perimeter. Each square represents 9 yd2.
area: about 22 yd2; perimeter: about 81 yd

area: about 198 yd2; perimeter: about 243 yd
area: about 198 yd2; perimeter: about 81 yd
d im pretty sure
hope this helps
To estimate the area and perimeter, multiply the number of 9 yd2 squares by 9 for the area and count the edge squares for the perimeter, considering that a square yard is 3 feet by 3 feet.
To estimate the area and perimeter of the figure where each square represents 9 yd2, we need to count the total number of squares for the area and the length of the edges in units of squares for the perimeter. If the figure has 22 full squares, then the area is 22 multiplied by 9 yd2, which equals 198 yd2.
To find the perimeter, count the number of squares along the outer edge of the figure, and multiply by the side length of each square. Assuming that the side length of each square is 3 yards (since a square yard is 3 feet by 3 feet, and 1 yard equals 3 feet), if the perimeter in squares is 27, then the perimeter in yards would be 27 yd.

What do you call it when a plane comes down in garbage heap
It is called "trash landing". :)
This is a show of word play which sounds similar to “crash landing” (trash/crash), crash landing is actually an organized landing made by an airplane because of a crisis containing a fast approaching or continuous danger to the well being and activity of the flying machine, but in this case as the plane land in garbage the word “crash” is replaced by “trash” giving a humorous meaning to the phrase.
Hope this helped :)
A crash landing describes a plane coming down in a garbage heap, whereas a stall refers to the loss of lift on an airplane's wings, which may not lead to a crash. The term 'Vomit Comet' is used for an aircraft simulating weightlessness in a controlled fall, different from a crash scenario.
When a plane comes down in a garbage heap, it can be referred to as a crash landing in a less formal context, especially if the aircraft is damaged in the process. In aviation, a stall is a condition in which the airplane's wings lose lift due to an insufficient angle of attack, but it does not necessarily result in a crash. Engine failure, which people often confuse with a stall, does not always result in a plane coming down immediately; pilots are trained to handle such situations and aim for a safe landing. In training simulations, astronauts and pilots may experience controlled falls to mimic various scenarios, such as the 'Vomit Comet' used for simulating weightlessness. However, such controlled descents are carefully managed to avoid accidents.
Environmental aspects can also be considered when relating a plane's descent to garbage heaps. For example, the way resources are depleted and environmental sinks become overwhelmed, as mentioned in 'The Tragedy of the Commons,' can be analogous to how an overloaded trash can at a concert spills over, drawing a parallel to the ecological impacts of mishandled waste.

Explanation:The correct ordered pairs for the equation y = -4x + 5 are (-1, 9) and (1, 1).
To determine if an ordered pair is a solution to the equation, substitute the x and y values into the equation and check if the equation holds true. For example, for the ordered pair (-1, 9):
y = -4x + 5
9 = -4(-1) + 5
9 = 4 + 5
9 = 9
Since the equation is true, (-1, 9) is a solution to the equation.

Solve x42=37 x 42 = 3 7 using two different strategies. Explain each strategy.
Given equation : [tex]\frac{x}{42}=\frac{3}{7}[/tex].
Strategy 1: We can cross mutiply both sides remove fraction form.
On cross multiplication, we get
x * 7 = 3 * 42
7x = 126.
Dividing both sides by 7, we get
x = 18.Strategy 2: We can find least common denominator(lcd) of both sides and multiplying both sides by that lcd to get rid denominators from both sides.
LCD of 42 and 7 is 42.
Therefore, multiplying both sides by 42, we get

Explain the differnce between function and relation and the relationship between the domain and the range of a function.
A relation is a set of numbers that have a relationship through the use of a domain and a range, while a function is a relation that has a specific set of numbers that causes there to be only be one range of numbers for each domain of numbers. All functions are relations, but all relations are not functions.
Given two sets [tex] A [/tex] and [tex] B [/tex], the "starting" set is called the domain, while the "landing" set is called the codomain.
With that being said, a relation is any way you can associate any number of elements in the domain with every number of elements in the codomain.
A function has more restriction: you can associate one and only one output for every input.
If you visualize this with arrows linking domain and codomain, in order for a relation to be a function, only one arrow can start from each point in the domain.
The domain is thus the set of elements from whence an arrow starts. The range is the subset of the codomain, given by the elements that are reached by at least one arrow.
A certain arithmetic sequence has this explicit formula for the nth term: an = 11 + (n – 1)(4) The same sequence has this recursive formula: an = an–1 + What number belongs in the blank space in the recursive formula?
a.15
b.11
c.3
d.4
Answer:
I would say D
Answer:
4
Step-by-step explanation:
A certain arithmetic sequence has this explicit formula for the nth term:
[tex]a_n = 11 + (n- 1)(4)[/tex]
Substitute n = 1
[tex]a_1 = 11 + (1- 1)(4)[/tex]
[tex]a_1 = 11 [/tex]
Substitute n =2
[tex]a_2 = 11 + (2- 1)(4)[/tex]
[tex]a_2 = 15[/tex]
[tex]d= a_2-a_1=15-11=4[/tex]
So,[tex]a_2=a_1+d=11+4=15[/tex] --1
Substitute n = 3
[tex]a_3 = 11 + (3- 1)(4)[/tex]
[tex]a_3 = 19[/tex]
[tex]a_3=a_2+d=15+4=19[/tex] ---2
So, with 1 and 2
Recursive formula : [tex]a_n=a_{n-1}+d[/tex]
Since d is 4
So, the number belongs in the blank space in the recursive formula is 4.

the price p of a clubs membership is $30 foran enrollment fee and $12 per week w tobe a member .Write a function
The function would be
p = $30 + $12w
or
p = $12w + 30
The function representing the total cost of the club membership is p(w) = 12w + 30, where 'w' is the number of weeks.
Explanation:The student is essentially asking to write a function which represents the cost of a club membership based on a fixed fee and a weekly cost. This is an example of a linear function in the form of y = mx + b. In this case, 'y' is the total cost 'p', 'm' is the weekly cost $12 (w), 'x' is the number of weeks, and 'b' is the fixed enrollment fee $30.
Thus, the function representing the total cost of the club membership is p(w) = 12w + 30. This equation can be used to find the total cost of the club membership for any number of weeks 'w'.

Answer: w = 4tFind the value of k the diagram is not to scale.
Answer:
[tex]k=73[/tex]
Step-by-step explanation:
We have been given a triangle. We are asked to find the value of k for our given triangle.
We will use angle sum property to solve for k. The angle sum property states that all angles of triangle add up-to 180 degrees.
[tex]k+62^{\circ}+45^{\circ}=180^{\circ}[/tex]
[tex]k+107^{\circ}=180^{\circ}[/tex]
[tex]k+107^{\circ}-107^{\circ}=180^{\circ}-107^{\circ}[/tex]
[tex]k=73^{\circ}[/tex]
Therefore, the value of k is 73.
The value of [tex]\angle{k}[/tex] is [tex]\fbox{\begin\\\ \bf 73^{\circ}\\\end{minispace}}[/tex].
Further explanation:
Consider, the given triangle as [tex]\triangle{ABC}[/tex] shown in figure 1.
Now, the value of [tex]\angle{A}[/tex] is 62 degree, the value of [tex]\angle{B}[/tex] is 45 degree and the value of [tex]\angle{C}[/tex] is [tex]k[/tex] .
From the property of the triangle, we know that sum of angles of a triangle is equal to 180 degree.
Now, for [tex]\triangle{ABC}[/tex] it can be written as follows:
[tex]A+B+C=180[/tex] ……(1)
Substitute 62 for [tex]A[/tex], 45 for [tex]B[/tex] and [tex]k[/tex] for [tex]C[/tex] in equation (1) to obtain the value of [tex]k[/tex].
[tex]\begin{aligned}62+45+k&=180\\107+k&=180\\k&=180-107\\k&=73\end{aligned}[/tex]
Thus, the value of angle [tex]k[/tex] is [tex]\fbox{\begin\\\ \bf 73^{\circ}\\\end{minispace}}[/tex].

What type of lines are these? Y = 2x + 4 and 2y = -4x + 10
ANSWER
The lines are two intersecting lines. They intersect` at the point [tex](\frac{1}{4}, \frac{9}{2})[/tex]
EXPLANATION
To determine which type of lines, we look for the slopes of the two lines and compare them to see whether they are parallel or perpendicular.
The first line is [tex]y=2x+4--(1)[/tex].
This line is already in the form;
[tex]y=mx+c[/tex], which is referred to as the slope intercept form, where [tex]m=2[/tex] is the slope.
The second line is
[tex]2y=-4x+10[/tex]
Dividing through by 2 gives;
[tex]y=-2x+5--(2)[/tex]
This implies that, this line also has a slope of [tex]-2[/tex].
Since the two slopes are not the same,the lines are not parallel.
Also the the product of the two slopes, [tex]-2\times 2 \ne -1[/tex], hence the two lines are not perpendicular.
Adding equation (1) and (2) gives;
[tex]2y=9[/tex]
[tex]\Rightarrow y=4.5[/tex]
Putting [tex]y=4.5[/tex] in equation (1) gives
[tex]4.5=2x+4[/tex]
[tex]\Rightarrow 0.5=2x[/tex]
[tex]\Rightarrow x=\frac{1}{4}[/tex].
Hence the two lines intersect` at the point [tex](\frac{1}{4}, \frac{9}{2})[/tex]

The equation of a line is 4x−3y=−24.
What is the x-intercept of the line?
x-intercept → y = 0
substitute to 4x - 3y = -24:
4x - 3(0) = -24
4x - 0 = -24
4x = -24 |divide both sides by 4
x = -6
How to work this out ?
Answer:
The solution is (-3, -2).
Step-by-step explanation:
Please note that if you simply add these 2 equations together, 9x - 9x = 0, and you are then left with -5y = 10. Thus, y = -2. Subbing -2 for y in the first equation, we get 9x - 8(-2) = -11, or 9x + 16 = -11.
Subtracting 16 from both sides, we get 9x = -27, so that x = -3.
The solution is (-3, -2).
