In the figure below, triangle ABC is similar to triangle PQR, as shown below: What is the length of side PQ?
A right triangle ABC with right angle at B and base BC is drawn. Length of AB is 4, length of BC is 2. A similar right triangle; triangle PQR, which is triangle ABC enlarged and reflected across a horizontal line, is drawn near it. The right angle is at Q. Angle A is congruent to angle P and angle C is congruent to angle R. The length of QR is 12.
Answers
The corresponding side of QR is BC
BC = 2 and QR = 12
As you can see QR is 6 times longer than BC and so PQ should be proportional to AB by the same factor.
if AB is 4 then multiply that by 6:
4 x 6 = 24

find the volume of the cylinder 13mm and 16mm
Answers
The volume of the cylinder is approximately 8491 mm³.
To find the volume of a cylinder, we use the formula:
[tex]\[ \text{Volume} = \pi \times \text{radius}^2 \times \text{height} \][/tex]
Given:
Radius [tex](\( r \))[/tex] = 13 mm
Height [tex](\( h \))[/tex] = 16 mm
Substitute the values into the formula:
[tex]\[ \text{Volume} = \pi \times (13)^2 \times 16 \][/tex]
[tex]\[ \text{Volume} = \pi \times 169 \times 16 \][/tex]
[tex]\[ \text{Volume} = \pi \times 2704 \][/tex]
Using an approximate value of [tex]\( \pi \)[/tex] as 3.14:
[tex]\[ \text{Volume} \approx 3.14 \times 2704 \][/tex]
[tex]\[ \text{Volume} \approx 8491.36 \, \text{mm}^3 \][/tex]
Rounded to the nearest whole number, the volume is approximately 8491 mm³, which matches option B. Therefore, the correct answer is B.

Let L, W, N represent the length in feet, width in feet, and number of floors (count). Then it seems we can write
.. L = W +40 . . . . . length is 40 ft more than width
.. 10LW +35000N = 1180000 . . . . . cost is based on foundation area and number of floors. (Here, we assume the 1st floor is sandwiched between the foundation at ground level and whatever it is that is 12 ft high and costs 35,000.)
.. 2(L +W) = 3*(12N) . . . . the height is 12 ft times the number of floors, and the perimeter is 3 times that.
These give rise to a quadratic equation.
.. 10L(L -40) +35000(L +(L -40))/18 = 1180000
Eliminating fractions and dividing by 10, we get

The positive solution is

Answers
Intuitively, you can imagine that the triangle is simply being "scaled up" by a factor of 7/3, so the base scales up to 7/3 its original length and the height becomes 7/3 its original height.
Therefore, the new ratio is the square of the ratio of the perimeters, which is 9:49.

“You are collecting email addresses from 74 customers per day, which is about 90% of the daily goal of emails per day.”
Answers
74 = 0.90x , where x is the daily goal of emails per day.
Dividing both sides by 0.90 gives x = 82.222. We can round down to 82 emails.
Final answer:
To find the daily email goal when 74 is 90%, we divide 74 by 0.9, leading to approximately 82.22 emails. The importance of email is underscored by the billions of users and emails sent daily, highlighting its role in business communication.
Explanation:
The student's question pertains to the calculation of a daily email collection goal based on the collection of email addresses from 74 customers, which they've stated is 90% of that goal.
To find the total daily goal, we can set up a proportion where 90% (or 0.9) of the goal equals 74 customers. We use a simple algebraic equation to solve for the total goal (G): 0.9 * G = 74. Dividing both sides by 0.9 gives us G = 74 / 0.9, which gives us the total goal as approximately 82.22 customers per day.
It's important to understand the context and relevance of emails in our daily lives. As of 2023, there are over 4.2 billion email users globally with up to 60 billion emails sent daily.
This vast number shows the significance of email communication, especially in business communication, making it a fundamental skill to manage effectively. With an average office worker receiving 120 emails daily, it becomes clear why being effective with email correspondence is crucial.

A baker has a bin filled with 30 cups of flour. His signature cake requires one and a half cups of flour. Determine which graph and which equation represent the amount of flour in the bin, F, after he bakes c signature cakes.
Answers
The equation for the flour left in the bin after baking c number of cakes is F = 30 - 1.5*c. This equation can be graphed with flour left, F, on the vertical axis and the number of cakes, c, on the horizontal axis, producing a downward sloping line.
Explanation:The subject of this question is mathematics and it focuses on linear equations and graphical representations. To answer this question, consider that the baker uses one and a half cups of flour for each cake. So, if he bakes 'c' amount of cakes, then the total flour used will be 1.5*c cups. If he started with 30 cups of flour in the bin, after making 'c' cakes, the flour remaining, F, in the bin will be given by the equation F = 30 - 1.5*c. This is a linear equation and its graph would be a line with a negative slope (because the amount of flour decreases as more cakes are baked). On the graph, the vertical axis (y-axis) could be the amount of flour left 'F', and the horizontal axis (x-axis) would be the number of cakes 'c'. The line would start from the point (0,30) (since initially, when no cakes are baked, there are 30 cups of flour) and slope downwards.

The function f(x)=15000(0.96)^x represents the value in dollars of a vehicle x years after it has been purchased new. What is the average decrease in value per year between years 5 and 10? Please show all work!
Answers
Value of the car after 5 years will be:
[tex]f(5)=15000 (0.96)^{5}=12230.59 [/tex]
Value of the car after 10 years will be:
[tex]f(10)=15000 (0.96)^{10}=9972.49 [/tex]
The decrease in the value of car will be:
[tex]f(5)-f(10)=2258.10 [/tex]
Average decrease in the value of car will be:
[tex] \frac{2258.10}{10-5}=451.62 [/tex]
Thus, on average the value of car decreases by $451.62 between year 5 and 10.
To find the average decrease in value per year between years 5 and 10 of a vehicle, we plug in x=5 and x=10 into the given function, subtract the values, and divide by 5.
Explanation:To find the average decrease in value per year between years 5 and 10, we need to calculate the difference in value between those two years and then divide it by the number of years.
First, we find the value of the vehicle in year 5 by plugging in x = 5 into the function:
f(5) = 15000(0.96)^5
solving this equation gives us the value of the vehicle in year 5.
Next, we find the value of the vehicle in year 10 by plugging in x = 10 into the function:
f(10) = 15000(0.96)^10
solving this equation gives us the value of the vehicle in year 10.
Finally, we subtract the value in year 10 from the value in year 5 and divide by 5 (the number of years) to get the average decrease in value per year.

No vowels
The question actually starts right here. The preamble tells us that we can only use letters, no numbers, and no symbols. We are not asked to do anything. The first question makes no mention of there being anything special about m. It can be there or it most likely is not. This part of the problem is the first part.
First Part

At a wedding, there are 456 people spread out amongst 45 tables. There are no empty seats. The reception hall has tables that sit 12 people or 8 people. Write a system of equations that can be used to find the number of each type of table the restaurant has.
Answers
The system of equations is [tex]\[ \begin{cases} x + y = 45 \\ 12x + 8y = 456 \end{cases} \][/tex]
How did we arrive at this equation?
Let's denote the number of 12-person tables as [tex]\( x \)[/tex] and the number of 8-person tables as [tex]\( y \)[/tex]. Since there are 45 tables in total, we can express the first equation as:
[tex]\[ x + y = 45 \][/tex]
Now, considering the total number of people seated, we know that each person at a 12-person table occupies one seat, and each person at an 8-person table occupies one seat as well. The total number of people is 456. Therefore, the second equation is:
[tex]\[ 12x + 8y = 456 \][/tex]
So, the system of equations is:
[tex]\[ \begin{cases} x + y = 45 \\ 12x + 8y = 456 \end{cases} \][/tex]
These equations represent the conditions that the total number of tables is 45 and the total number of people seated is 456, with no empty seats.
