Using proportions, it is found that the value of x is of x = 5, hence option A is correct.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Since the triangles are similar, the lengths are proportional. Researching the problem on the internet, we have that the proportions are given as follows:
A side with a length of x is proportional to a side with length 25.A side with a length of 3 is proportional to a side with length 15.Hence:
[tex]\frac{x}{25} = \frac{5}{25}[/tex]
Simplifying the denominators:
x = 5.

Use the information in this table(in the attachment) to help you answer the questions. Remember, you have a budget of $20,000 for the car.
1. What add-on options do you want in your car?
Sun-roof, and Keyless entry
2. Write an inequality to model purchasing a car from Dealership A with the desired add-on options and staying within your budget. Use x to represent the base price of the car. (Assume that only the base price of the car is taxed to simplify the problem.)
3. Solve for x. Explain in words what the solution to the inequality means.
4. Graph the possible base price values that are included in the solution. Please upload an image of your graph.
5. Complete 2–4 for Dealership B using the same add-on options.
Will you buy from Dealership A or from Dealership B? Why?
The best buy is from dealership B because dealership B has a lesser base price
The add-on optionsFor the purpose of this exercise, the add-on options to select are:
SunroofKeyless entryDealership AThe total amount of the add-on options is:
Total = $500 + $1500
Total = $2000
The inequality
This is represented using:
Base price * (1 + Tax) + Fees + Add-on total ≤ 20000
So, we have:
(1 + 6.75%) * x + 751.56 + 2000 ≤ 20000
Solve for x
We have:
(1 + 6.75%) * x + 751.56 + 2000 ≤ 20000
Evaluate the like terms
(1 + 6.75%) * x ≤ 17248.44
Divide both sides by (1 + 6.75%)
x ≤ 16157.79
The solution means that the base price of the car cannot exceed $16157.78 for dealership A
The graph of the possible base price
See attachment
Dealership BThe total amount of the add-on options is:
Total = $750 + $1000
Total = $1750
The inequality
This is represented using:
Base price * (1 + Tax) + Fees + Add-on total ≤ 20000
So, we have:
(1 + 6.75%) * x + 1524.72 + 1750 ≤ 20000
Solve for x
We have:
(1 + 6.75%) * x + 1524.72 + 1750 ≤ 20000
Evaluate the like terms
(1 + 6.75%) * x ≤ 16725.28
Divide both sides by (1 + 6.75%)
x ≤ 15667.71
The solution means that the base price of the car cannot exceed $15667.71 for dealership B

A. 54.5 miles
B. 57.5 miles
C. 59.5 miles
D. 62.5 miles
Answer:
D. 62.5
Step-by-step explanation:
2 ways
1.
7.5 ÷ 3 = 2.5
25 times 2.5 = 62.5
2.
3/7.5 = 25/x
3x = 187.5
187.5 ÷ 3 = 62.5
The actual distance for a length on a map is 62.5. so correct option is D.

the volume of a cylinder is 539 cm cube and the circumference of the base is 22 cm. find the height of the cylinder.
Answer:
13.994[tex]cm (5.sf)[/tex]
Step-by-step explanation:
We know that the base of the cylinder is a circular base.
So circumference of base = [tex]2\pi r[/tex]
Given [tex]2\pi r=22cm\\\\r=\frac{22}{2\pi } \\r=\frac{11}{\pi } cm\\[/tex]
Volume of a cylinder = [tex]\pi r^{2} h[/tex] = 539[tex]cm^{3}[/tex]
Substitute r into the formula for volume of cylinder.
[tex]\pi (\frac{11}{\pi } )^{2} h=539\\\pi (\frac{121}{\pi ^{2} } )h=539[/tex]
Now, we will cancel [tex]\pi[/tex] from the numerator and denominator.
[tex](\frac{121}{\pi } )h=539\\h = \frac{539}{\frac{121}{\pi } } \\h = 539 * \frac{\pi }{121} \\h = 13.994cm(5s.f)[/tex]
Answer:
Aproximated height is:
14 cm
Step-by-step explanation:
volume of a cylinder = л r² h
л = 3.1416 (aprox)
r = radius
h = height
r = circunference/2л
r = 22/(2*3.1416)
r = 3.5 (aprox)
then volume is:
539 = 3.1416 * 3.5² * h
539 = 3.1416 * 12.25 * h
539 = 38.5 * h
h = 539/38.5
h = 14 cm (aprox)
Is -(3x + 5)^2 a perfect trinomial? Why or why not?
The given equation-(3x + 5)^2 is not a perfect trinomial because it is not obtained through the multiplication of a binomial.
