Two enterprising college students decide to start a business. They will make up and deliver helium balloon bouquets for special occasions. It will cost them $39.99 to buy a machine to fill the balloons with helium. They estimate that it will cost them $2.00 to buy the balloons, helium and ribbons needed to make each balloon bouquet. Which of the following expressions could be used to model the total cost for producing b balloon bouquets?
$2.00b + $39.99$37.99b$39.99b + $2.00$41.99bSave
Answer:
Option A.
Step-by-step explanation:
Machine to fill the balloons with helium will cost = $39.99
Cost of the balloons, helium and ribbons for each bouquet = $2.00
If b balloon bouquets are produced then cost of b balloon bouquets = $2b
Total cost for producing b balloon bouquets = cost of machine + cost of material
= $(39.99 + 2b)
Therefore, cost to produce b bouquets will be $2.00b + $39.99
Hence option A is the answer.

Answer:
Tony pays $6.75 for his item, & Tanya pays $9 for her items
Step-by-step explanation:
Let Tanya's item be x, and Tony's be y. Set the system of equality:
3x = 4y
y = x - 2.25
Plug in x - 2.25 for y in the first equation
3x = 4(x - 2.25)
Distribute 4 to all terms within the parenthesis
3x = 4x - 9
Isolate the x. Subtract 4x from both sides
3x (-4x) = 4x (-4x) - 9
3x - 4x = -9
-x = -9
Isolate the x. Divide -1 from both sides
(-x)/-1 = (-9)/-1
x = 9
-------------------------------------------------------------------------------------------------------------------
Plug in 9 for x in the equation
y = x - 2.25
y = (9) - 2.25
y = 6.75
--------------------------------------------------------------------------------------------------------------------
Tony pays $6.75 for his item, & Tanya pays $9 for her items

Susanna spends a total 0f 47 minutes on her project. How many more minutes than Susanna does Abby spend working? Draw a number line to model the problem, and write an equation to solve.
a - 47 = more time spent
In this mathematical problem, Abby's time is represented as x and the difference in time between Abby's and Susanna's work can be modeled by the equation x-47=y, where y is the extra time Abby spends. A number line can be used to visualize this problem, but without knowing Abby's time, we cannot determine y.
Explanation:The subject of this problem is mathematics and it discusses time spent by two individuals on their project. We know that Susanna spends 47 minutes on her project. However, we do not know how much time Abby spends on her project. We could represent the time Abby spends on her project as x.
To visualize the situation, we can draw a number line. Place a point at 47 which represents Susanna's time. Then place another point at x which represents Abby's time.
The difference in time between Susanna and Abby can be represented by the equation x - 47 = y, where y is the number of extra minutes Abby spends working on her project.
Without any additional information on how much time Abby spent on her work, it's impossible to give a specific answer.

I believe it would be x5 considering you must add exponents when you multiply.
Answer:
[tex]x^3\cdot x^2=x^5[/tex]
Step-by-step explanation:
The rule to multiply two powers with the same base consists in adding the exponents. The general form would be:
[tex]x^a\cdot x^b=x^{a+b}[/tex]
For verifying the previous rule, let's say that x=2, a=2 and b=3. The equation would be:
[tex]2^2\cdot 2^3=2^{5}[/tex]
[tex](4)\cdot (8)=2^{5}[/tex]
[tex]32=32[/tex]
We have obtained the result multiplying individually and applying the rule.
Now, for the [tex]x^3\cdot x^2[/tex] exercise, the result would be obtained by adding 3 and 2. It would be:
[tex]x^3\cdot x^2=x^{3+2}=x^5[/tex]

Ella owns 15% of Fitz Incorporated. The rest of the shares are owned equally by the remaining 5 shareholders. What percent of the corporation does each of the other shareholders own?
Answer:
17%
Step-by-step explanation:
The total corporation shares is 100%If Ella owns 15% of Fitz,the remaining shares is 100-15=85%If there are 5 shareholders and they all own equal shares,the percentage for each shareholder will be;85/5=17% eachFinal answer:
Ella owns 15% of Fitz Incorporated, and the remaining 85% is shared equally among 5 other shareholders. Thus, each of these shareholders owns an equal share of 17% of the corporation.
Explanation:
The question asks about corporate stock and how it relates to the percentage of ownership in a corporation. Ella owns 15% of Fitz Incorporated, and the remaining 85% is owned equally by 5 other shareholders. To find the percentage each of these shareholders owns, we divide the remaining percentage by the number of shareholders.
The calculation would be:
Subtract the percentage owned by Ella from the total, which is 100% - 15% = 85%.
Divide this remaining percentage (85%) by the number of other shareholders, which is 5.
85% / 5 = 17% ownership for each of the other shareholders.
So, each of the remaining 5 shareholders owns 17% of the corporation.

I don’t understand this. In class we have been doing these problems with only one transversal, not two.
Answer: Yes it is possible. Angle DCF is also 50 degrees
=================================================
Check out the image attachment below. On that image, I've marked that angle EBA is congruent to angle BAC by the alternate interior angle theorem. Those angles are shown in red. Furthermore, angle BAC is congruent to DCF (corresponding angles) using a green marker. Finally, using the transitive theorem, you can connect the statements in a chain to say that angle EBA is congruent to angle DCF, which is why angle DCF is 50 degrees as well.

What is the complement of a single die being rolled to a number greater than 2
a single die being rolled to a number less or equal to 2
Final answer:
The complement of rolling a number greater than 2 on a single six-sided die is rolling a 2 or less, which has a probability of 1/3.
Explanation:
In the context of a single six-sided die roll, the complement of rolling a number greater than 2 would be rolling a number that is 2 or less, which in this case includes rolling a 1 or a 2. Each face of a fair six-sided die has an equal chance of landing face up, giving us a probability of 1/6 for landing on a specific number. Since there are two outcomes that are 2 or less (1 and 2), we simply add their probabilities to get the complement. Thus, the complement of rolling a number greater than 2 is:
P(rolling a 1 or 2) = P(rolling a 1) + P(rolling a 2)
= 1/6 + 1/6
= 1/3.
Therefore, there is a 1/3 chance of rolling a number that is 2 or less when rolling a single fair six-sided die.

The function p(x)=8x-10 shows the profit, in dollars, for selling x books.
p(10) is the profit, in dollars, from selling 10 books. Replace every copy of x with 10 and simplify
p(x) = 8x-10
p(10) = 8*10-10 .... every x is replaced with 10
p(10) = 80-10
p(10) = 70
So the profit is $70
For the function p(x) = 8x - 10, the profit for selling 20 books is $150.
Explanation:
In the problem, the function p(x) = 8x - 10 represents the profit, in dollars, for selling 'x' books. When it's stated that p(20) = 150, it means that by substituting the value of 'x' as 20 in the function, we get the value as 150. In terms of the problem, it means that the profit for selling 20 books is $150.
Let's break down the problem step by step.
1. You're given the function p(x) = 8x - 10, which represents the profit, in dollars, for selling x books. In this equation, p(x) is the profit, and \(x\) is the number of books sold.
2. You're asked to evaluate the function at x = 20, which means you want to find p(20). To do this, substitute x = 20 into the function and calculate the result.
p(20) = 8(20) - 10
3. Perform the calculation:
p(20) = 160 - 10
4. Complete the subtraction:
p(20) = 150
So, p(20) = 150, which means that the profit for selling 20 books is $150. This is the interpretation of the statement "p(20) = 150" in terms of the problem.
