Answer:
3,600 from $26 tickets and 1,400 from $40 tickets.
Step-by-step explanation:
Let x = number of $26 tickets and y= number of $40 tickets
x + y = 5000 ⇒ x = 5000 - y
26x + 40y = 149,600
26(5000 - y) + 40y = 149600
130,000 - 26y + 40y = 149600
14y = 19600
y = 19600/14 = 1,400
x = 5000 - 1400 = 3,600
So, 3,600 from $26 tickets and 1,400 from $40 tickets.
To determine the number of tickets sold at each price, set up a system of equations using the given information and solve for the variables.
Explanation:To determine how many tickets should be sold at each price, we can set up a system of equations using the given information.
Let's assume the number of $26 tickets sold is x and the number of $40 tickets sold is y.
The total number of tickets sold is x + y, so we have the equation x + y = 5000.
The revenue generated from $26 tickets is 26x, and the revenue generated from $40 tickets is 40y. The total revenue
is given as $149,600, so we have the equation 26x + 40y = 149600.
Solving this system of equations will give us the values of x and y.
Raphael runs every day for a number of weeks. He runs for 35 days in a row. How many weeks did he run?
Answer:
2 weeks and 5 days
Step-by-step explanation:
Final answer:
Raphael ran for a total of 5 weeks, calculated by dividing the total number of days he ran (35 days) by the number of days in a week (7 days).
Explanation:
Raphael runs for 35 days in a row, and we need to calculate how many weeks he runs. A week consists of 7 days. To find out the number of weeks Raphael ran, we divided the total number of run days by the number of days in a week.
Number of weeks = Total run days / Days in a week = 35 / 7 = 5
Therefore, Raphael ran for 5 weeks, illustrating the duration of his consistent running routine in terms of weeks. This computation provides a clear understanding of the duration of Raphael's running streak in a familiar time frame, aiding in tracking and planning his exercise regimen.

6) 40 percent of 25 is 10.
Step-by-step explanation:
1). 21 is what percent of 168.
Let,
x be the percent.
Therefore,
x% of 168 = 21
[tex]\frac{x}{100}*168=21[/tex]
[tex]1.68x=21[/tex]
Dividing both sides by 1.68
[tex]\frac{1.68x}{1.68}=\frac{21}{1.68}\\x=12.50[/tex]
21 is 12.50% of 168.
2). What is 4 percent of 150.
4% of 150 = [tex]\frac{4}{100}*150[/tex]
4% of 150 = [tex]\frac{600}{100} = 6[/tex]
4% of 150 is 6.

Describe how to solve the inequality 3x+4<13 using algebra tiles
The solution is x < 3.
Solution:
The given expression is 3x + 4 < 13.
To solve the given inequality.
3x + 4 < 13
Subtract 4 tiles on both sides of the inequality.
⇒ 3x + 4 – 4 < 13 – 4
⇒ 3x < 9
Divide by 3 tiles on both sides of the inequality.
⇒ [tex]\frac{3x}{3} =\frac{9}{3}[/tex]
⇒ x < 3
Hence the solution is x < 3.
Final answer:
To solve the inequality using algebra tiles, represent 3x+4 with tiles on one side and 13 units on the other, remove 4 units from both sides to get 3x < 9 and then divide the remaining 9 units into 3 groups to find x < 3.
Explanation:
To solve the inequality 3x+4<13 using algebra tiles, we follow these steps:
Start by representing the inequality with algebra tiles. Place 3 x-tiles (each representing 'x') and 4 unit tiles (each representing '1') on one side of a mat to model the expression 3x+4.
On the other side, place 13 unit tiles to represent the number 13.
To isolate the variable x, we need to remove the same number of unit tiles from each side. Remove 4 unit tiles from each side of the mat, which corresponds to Subtracting 4 from both sides of the inequality.
After removal, the inequality on the mat now shows 3x tiles on one side and 9 unit tiles on the other, representing the inequality 3x < 9.
Lastly, to find the value of one x-tile, divide the remaining unit tiles into 3 equal groups. Since there are 9 units left, each group will consist of 3 unit tiles, indicating that each x-tile is less than 3. This gives us the final inequality x < 3.
From this process, we've determined that for the original inequality 3x+4<13, the solution is x<3.

If c (x) = StartFraction 5 Over x minus 2 EndFraction and d(x) = x + 3, what is the domain of (cd)(x)?
all real values of x
all real values of x except x = 2
all real values of x except x = –3
all real values of x except x = 2 and x = –3
Answer:
The domain of the function (cd)(x) will be all real values of x except x = 2.
Step-by-step explanation:
The two functions are [tex]c(x) = \frac{5}{x - 2}[/tex] and d(x) = x + 3
So, (cd)(x) = [tex](\frac{5}{x - 2})(x + 3) = \frac{5(x + 3)}{x - 2}[/tex]
Then, for x = 2 the function (cd)(x) will be undefined as zero in the denominator will make the function (cd)(x) undefined.
Therefore, the domain of the function (cd)(x) will be all real values of x except x = 2. (Answer)

Step-by-step explanation:
Quadratic Equations
The quadratic equation has the following general form
[tex]ax^2+bx+c=0[/tex]
It can be solved by several methods, including the well-known quadratic formula
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
The question requires us to find a number that added with its reciprocal results 2 9/10. If x is the required number
[tex]\displaystyle x+\frac{1}{x}=2\ \frac{9}{10}=\frac{29}{10}[/tex]
Operating
[tex]\displaystyle \frac{x^2+1}{x}=\frac{29}{10}[/tex]
Rearranging
[tex]10(x^2+1)=29x[/tex]
[tex]10x^2-29x+10=0[/tex]
Comparing with the general quadratic equation, we have
[tex]a=10,\ b=-29,\ c=10[/tex]
Using the formula
[tex]\displaystyle x=\frac{29\pm \sqrt{(-29)^2-4(10)(10)}}{2(10)}[/tex]
[tex]\displaystyle x=\frac{29\pm \sqrt{441}}{20}=\frac{29\pm 21}{20}[/tex]
It gives us two possible solutions
[tex]\displaystyle \boxed{x=\frac{5}{2}, x=\frac{2}{5}}[/tex]
Both are valid solutions since
[tex]\displaystyle \frac{5}{2}+\frac{2}{5}=\frac{29}{10}[/tex]

Which graph shows the result of dilating this figure by a factor 1/3 about the origin
Plot the vertices A'(-12, 9), B'(9, 3), and C'(6, -3) on the coordinate plane. Label them as A', B', and C', respectively.
To determine the coordinates of the dilated triangle A'B'C', we can follow these steps:
1. Find the coordinates of the original triangle's vertices: A(-4, 3), B(3, 3), and C(2, -1).
2. Dilate each vertex from the origin by a scale factor of 3. This means we will multiply the x and y coordinates of each vertex by 3.
- For vertex A: Multiply -4 by 3 to get -12 and multiply 3 by 3 to get 9. Therefore, the coordinates of A' are (-12, 9).
- For vertex B: Multiply 3 by 3 to get 9. The y-coordinate remains the same at 3. Therefore, the coordinates of B' are (9, 3).
- For vertex C: Multiply 2 by 3 to get 6 and multiply -1 by 3 to get -3. Therefore, the coordinates of C' are (6, -3).
3. Plot the vertices A'(-12, 9), B'(9, 3), and C'(6, -3) on the coordinate plane. Label them as A', B', and C', respectively.
Note: The original triangle ABC remains unchanged on the coordinate plane.
By following these steps, you will have successfully determined the coordinates of the dilated triangle A'B'C' and plotted it on the coordinate plane.

disjoint subsets A and B of a universal set U, except assume that n(U)=120, n(A)=45, and n(B)=50.
Then n(A′∪B)=
Answer:
n (A' U B ) = 75
Step-by-step explanation:
Here, given : n(U)=120, n(A)=45, and n(B)=50
As we know:
n (A ' U B) = n(A) − n (A∩B) ... (1)
Here, n(A) = 45
So, n( A') = n(U) - n(A) = 120 - 45 = 75
⇒ n(A') = 75
Now, as given A and B are disjoint sets.
⇒ n (A ∩ B) = Ф
So, (A' U B ) = A'
So, n (A' U B ) =n( A') = 75
⇒ n (A' U B ) = 75
Is 57 a prime number
For 57 to be a prime number, it would have been required that 57 has only two divisors, i.e., itself and 1. However, 57 is a semiprime (also called biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 57 = 3 x 19, where 3 and 19 are both prime numbers.
Answer: No
Step-by-step explanation: For 57 to be a prime number, it would have been required that 57 has only 2 divisors, ie itself and 1. How ever 57 is a semiprime because it is the product of a two non- necessarily distinct prime numbers. inderd, 57= 3×19, where 3 and 19 are prime numbers.

6700 dollars is placed in an account with an annual interest rate of 8.25%. How much will be in the account after 28 years, to the nearest cent?
After 28 years, there will be approximately $48,505.29 in the account.
To calculate the amount of money that will be in the account after 28 years with an annual interest rate of 8.25%, we can use the formula for compound interest:
[tex]\[ A = P \times (1 + r)^n \][/tex]
Where:
- A is the amount of money accumulated after n years, including interest.
- P is the principal amount (the initial amount of money), which is $6700 in this case.
- r is the annual interest rate (in decimal form), which is 8.25% or 0.0825.
- n is the number of years, which is 28 in this case.
Plugging in the values into the formula:
[tex]\[ A = 6700 \times (1 + 0.0825)^{28} \][/tex]
Calculating the value:
[tex]\[ A = 6700 \times (1.0825)^{28} \][/tex]
[tex]\[ A \approx 6700 \times 7.2417 \][/tex]
[tex]\[ A \approx 48,505.29 \][/tex]

Answer:
15. ∠ABE = 50°
16. ∠EBD = 10n - 19
Step-by-step explanation:
If [tex]$ \overline{\textbf{BE}} $[/tex] bisects ∠ABD then we have ∠ABE = ∠DBE
So, we will have: (6x + 2)° = (8x - 14)°
⇒ 6x + 2 = 8x - 14
⇒ 8x - 6x = 14 + 2
⇒ 2x =16
⇒ x = 8
∴ ∠ABE = 6(8) + 2
= 48 + 2
= 50°
∴∠ABE = 50°
16. If [tex]$ \overline{\textbf{BE}} $[/tex] bisects ∠ABD then ∠ABE + ∠EBD = ∠ABD
⇒(12n - 8) + ∠EBD = (22n - 11)
⇒ ∠EBD = 22n - 11 - 12n + 8
⇒ ∠EBD = 10n - 3
Hence, the answer.
Erica and her sister Laura are making baby blankets to sell at a boutique. Erica has already completed 10 blankets and can finish 6 more blankets per day. Laura has already completed 6 blankets and can finish 10 more blankets per day. At some point, they will have completed the same number of blankets. How many blankets will each woman have made? How long will that take?
Answer:
Laura and Erica will both have made 16 blankets in one more day.
Step-by-step explanation:
i) Erica has made 10 blankets already.
ii) Erica can make 6 blankets more per day
iii) Laura has completed 6 blankets already
iv) Laura can complete 10 more blankets per day.
v) Let x be the number of days to the point when they will have completed the same number of blankets
vi) Therefore the number of blankets that Erica makes till x days is = to the number of blankets that Laura makes till x days
vi) therefore 10 + 6x = 6 + 10x ⇒ 4x = 4 ⇒ x = 1 day
vii) Therefore Laura and Erica will both have made 16 blankets in one more day.
