Final answer:
Tripling the side lengths of a pentagon multiplies its perimeter by three, resulting in a new perimeter that is three times the original perimeter.
Explanation:
When we triple the side lengths of a pentagon, we essentially multiply the length of each side by three. Since a pentagon has five sides, if each side is tripled, the new perimeter will be three times the original perimeter. This is because the perimeter of any polygon is the sum of the lengths of its sides. In a more mathematical expression, if the original length of a side of the pentagon is s, the perimeter (P) of the original pentagon is 5s. When we triple the side length, each side becomes 3s, making the new perimeter P' to be 5(3s) = 3(5s) or simply three times the original perimeter, which is 15s.

A scale drawing of a billboard uses the scale 4cm:9 ft. The length of the billboard in the drawing is 11 cm. How long is the actual billboard
The length of the actual billboard is 24.75 ft.
What is Scale Factor?A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size. It is used to find the missing length, area, or volume of an enlarged or reduced figure as well as to draw the enlarged or reduced shape of any given figure.
Given:
Scale: 4cm : 9 ft
So, 1 cm = 9/4 ft
Then, length = 11cm
= 11 x 9/4
= 99/4
= 24.75 ft
Hence, the length is 24.75 feet.

Eder needs 6 cookies and 2 brownies for every 4 plates he makes for a bake sale. Drag cookies and brownies into the box to show how many Eder needs for 10 plates.
Answer:
Eder needs 15 cookies and 5 brownies for every 10 plates he makes.
Step-by-step explanation:
In order to know hoy many cookies and brownies Eder needs for 10 plates, given the fact that he needs 6 cookies and 2 brownies for every 4 plates, we need to perform the following calculation:
6C + 2B = 4X (plates)
6/4C + 2/4B = X
1.5C + 0.5 B = X
So, as we can see, 1.5 cookies and 0.5 brownies are needed for every plate. To know how many of those are needed for ten plates, we ned to multiply those numbers by 10.
1.5 x 10 = 15
0.5 x 10 = 5
Eder needs 15 cookies and 5 brownies for every 10 plates he makes.
Walt received a package that is 2 1/3 inches long, 6 3/4 inches high, and 8 1/2 inches wide. What is the surface area of the package?
Answer : The surface area of the package is, [tex]185.9inch^3[/tex]
Step-by-step explanation :
The given package is in cuboid shape. Now we have to calculate the surface area of the package by using volume of cuboid.
Formula used for volume of cuboid is:
[tex]V=2(lb+bh+hl)[/tex]
where,
V = volume of package
l = length of package = [tex]2\frac{1}{3}inch=\frac{7}{3}inch[/tex]
b = width of package = [tex]8\frac{1}{2}inch=\frac{17}{2}inch[/tex]
h = height of package = [tex]6\frac{3}{4}inch=\frac{27}{4}inch[/tex]
Now put all the given values in the above formula, we get:
[tex]V=2\times [(\frac{7}{3}\times \frac{17}{2})+(\frac{17}{2}\times \frac{27}{4})+(\frac{27}{4}\times \frac{7}{3})][/tex]
[tex]V=2\times [\frac{119}{6}+\frac{459}{8}+\frac{63}{4}][/tex]
[tex]V=185.9inch^3[/tex]
Therefore, the surface area of the package is, [tex]185.9inch^3[/tex]

Use the given information to analyze what happened with the fundraiser.
What happens when the quantity is above the equilibrium point?
Answer:
If the quantity is above the equilibrium point, there is an oversupply.
Step-by-step explanation:
The demand and supply curves intersect at a point called the equilibrium point. At this point, the price and quantity of equilibrium are determined. If we increase the price of the products, there is a decrease in the quantity demanded.
If demand and supply are perfectly elastic, when the price increases, the quantity demanded decreases proportionally. Given this, we can deduce that the collection of funds did not vary from what they would have obtained by selling the rest of the t-shirts at the same price.
If the quantity is above the equilibrium point, there is an oversupply.

100 is not a reasonable estimate for the operation 915.25 divided by 88.22, as the actual answer is approximately 10.37. While estimates don't provide exact numbers, the difference here is too great for 100 to be considered reasonable, depending on the level of accuracy needed.
Explanation:In mathematics, estimation is commonly used when you do not need the exact answer, but rather a ballpark number close to the actual value. The student's question revolves around whether 100 is a reasonable estimate for the operation 915.25 divided by 88.22. We can check this by performing the actual division: 915.25 / 88.22 equals approximately 10.37. Although this is not exactly 100, it is within an order of magnitude which might make the estimate reasonable depending on the context. Therefore, as a quick estimate, 100 might not be suitable for high-precision contexts.
It's important to understand how estimates work. Their value is not in providing exact numbers, but in giving a quick understanding of a situation, especially when the exact numbers are complex or cumbersome. Here, however, the difference between the actual result (10.37) and the estimate (100) is quite significant, which suggests that 100 might not be a reasonable estimate in this case, depending on the level of accuracy needed.

Mr Nickelson tells the class that they double the least common denominator for 1/2 3/5 and 9/15 to find the number of the day what number is the number of the day
Given fractions are [tex] \frac{1}{2} ,\frac{3}{5} ,\frac{9}{15} [/tex]
To find the least common denominators of the given fractions, we need to find the least common multiple (L.C.M.) of the numbers given in denominators i.e. 2, 5, and 15.
Finding the LCM of 2, 5, and 15 :-
2 = 1 x 2
5 = 1 x 5
15 = 3 x 5
So least common multiple of 2, 5, and 15 would be (1 x 2 x 3 x 5) = 30.
Hence, common denominator would be 30.
The teacher tells us to double the common denominator to find the answer that is the number of the day.
So we need to double the value of common denominator i.e. 2 x 30 = 60.
It means that 60 is the number of the day.
Hence, 60 is the final answer.
The number of the day is 4.
Explanation:Least common denominator for 1/2 3/5 and 9/15
To find the least common denominator (LCD) for fractions, we need to find the smallest multiple that is common to all the denominators.
For 1/2, 3/5, and 9/15, the denominators are 2, 5, and 15 respectively.
To find the LCD, we need to double the smallest denominator, which is 2, resulting in an LCD of 4.
Therefore, the number of the day is 4.

The orientation of a figure changes when it is reflected across a line while its shape and size stay consistent, creating a mirror image with symmetry relative to the line of reflection.
When a figure is reflected across a line, its orientation changes, whereas the shape and size of the figure remain the same. The Law of Reflection implies that each point of the figure maintains its distance from the line of reflection but on the opposite side, creating a 'mirror image' or symmetric counterpart. This mirror image aligns with the original figure if an imaginary line were drawn perpendicular to the mirror (line of reflection) at each point, these perpendiculars would be equal in length on both sides. This reflection transformation is an example of a linear transformation, preserving the straightness of lines and parallelism of parallel lines.

Estella buys 1.8 pounds of walnuts for a total of $5.04. She solves the equation 1.8p=5.04 to find the price p in dollars of one pound of walnuts. what does one pound of walnuts cost?
Solution: Let the cost of one pound of walnuts= $p
So, The cost of 1.8 pound of walnuts=$1.8p
Whereas, The cost of 1.8 pound of walnuts=$5.04
So, 1.8p=5.04
Now, To solve for p, Let us isolate p
To isolate p, Let us divide by 1.8 on both sides
[tex] \frac{1.8}{1.8} p=\frac{5.04}{1.8} [/tex]
On dividing 5.04 by 1.8, we get 2.8
