The cost of a ticket to an amusement park is $42 per person. For groups of up to 8 people, the cost per ticket decreases by $3 for each person in the group. Marcos's ticket cost $30. Write and solve an equation to find the number of people in Marcos's group.
Answer:
Cost of each ticket per person = $42
For groups of up to 8 people, the cost per ticket decreases by $3 for each person in the group.
Marco's ticket cost $30.
This means he paid 42-30=12 dollars less.
Now when there are 8 members, the cost decreases by $3.
So, $12 will decrease, when there will be members
I hope this helps! Have an awesome day!

The value of a collectible coin can be represented by the equation y = 2 x + 9.74, where x represents the number of years that Consuello has owned the coin and y represents the total value, in dollars, of the coin. What was the value of the coin when Consuello originally purchased it? $4.87 $7.74 $9.74 $19.48
Answer:
you would multiply 2 * 4.87 and then add that to 9.74 and then you do that to everyone and then one of them will get you your answer and I am not sure about the answer but I think its b
Step-by-step explanation:
Answer:
The value of the coin when Consuelo originally purchased it is $9.74 ⇒ C
Step-by-step explanation:
The form of the linear equation is;
y = m x + b, where
m is the slope of the line (The rate)
b is the y-intercept (initial amount, value y at x = 0)
∵ The value of a collectible coin can be represented by the equation
y = 2 x + 9.74
→ Compare it with the form of the linear equation above
∴ m = 2
∴ b = 9.74
∵ x represents the number of years that Consuelo has owned the coin
∵ y represents the total value, in dollars, of the coin
→ That means the value of y at x = 0 is the value of the coin when
Consuelo originally purchased it
∵ b represents the value of y at x = 0
∵ b = 9.74
∴ The value of the coin when Consuelo originally purchased it is $9.74

Explanation:
The result of problem 7 is undefined because the matrices are not the same size. Both matrices must have the same number of rows, and they must have the same number of columns. This is so the terms match up when we add them. This applies to question 9 as well because subtraction is a form of addition.
For problem 8, we add the corresponding terms. So for instance, along the top we have -2+(-3) = -5 as the first entry in the top row. So that's why the answer is C for problem 8. Problem 10 and 11 are similar to this. Be careful to distribute the negative through to each term in the second matrix when subtracting matrices.
For problem 12, we multiply the outer 3 by each term inside the matrix. We end up with choice B.

-2(x + 6) = 5x - 10
The Answer: x = -2/7
Answer: x = 2/7 or 0.29
Step-by-step explanation:
- 2x - 12 = 5x - 10
- 2x - 5x = 12 - 10
- 7x = 2
x = 2/7 or x = 0.29

By rounding each number to 1 significant figure, estimate the answer to 39x52/ 3.8x4.9
Answer:
100
Step-by-step explanation:
Round off each number to 1 significant figure first.
(39×52)/(3.8×4.9) = (40×50)/(4×5)
Evaluate numbers in brackets.
(40×50)/(4×5) = 2000/20
Evaluate.
2000/20 = 100
The value of the expression will be equal to 100.

69 cents each. She used partial products to find the total cost in cents. Which are NOT possible partial products for 24 × 69? Choose all that apply. A. 24 B. 36 C. 180 D. 240
Answer:
A. 24
Step-by-step explanation:
If we have two digits to multiply together, the multiplication of the individual digit of those number with each other whereby each digit retain its place is known as partial product.
From the given question, by applying the distributive property method, the partial products are:
24 × 69 = 24 × (60 + 9)
open brackets
= (24 × 60) + (24 × 9)
By factorization
= 60 (20 + 4) + 9(20 + 4)
expanding the brackets, we get:
= (60 × 20) + (60 × 4) + (9 × 20) + (9 × 4)
= 1200 + 240 + 180 + 36 (These are the partial products)

Of those who said they would vote for proposition P,70 percent actually voted for P,and of those who did not say they would vote for P,20 percent actual voted for P.What percent of those polled voted for P
Answer:
60%
Step-by-step explanation:
Let the total number of people polled to vote be 1000
80% said they would vote for him
That is 800
20% said they would not vote for him
That is 200
Out of the 800, 70% actually voted
That will be ;
70/100 * 80 = 560
Also, 20% of the 200 that said they would not vote actually voted
That will be ;
20/100 * 200 = 40
Total is thus;
569 + 40 = 600

Answer:
[tex]\sin 2A + \csc 2A = 2.122[/tex]
Step-by-step explanation:
Let [tex]f(A) = \sin A + \csc A[/tex], we proceed to transform the expression into an equivalent form of sines and cosines by means of the following trigonometrical identity:
[tex]\csc A = \frac{1}{\sin A}[/tex] (1)
[tex]\sin^{2}A +\cos^{2}A = 1[/tex] (2)
Now we perform the operations: [tex]f(A) = 3[/tex]
[tex]\sin A + \csc A = 3[/tex]
[tex]\sin A + \frac{1}{\sin A} = 3[/tex]
[tex]\sin ^{2}A + 1 = 3\cdot \sin A[/tex]
[tex]\sin^{2}A -3\cdot \sin A +1 = 0[/tex] (3)
By the quadratic formula, we find the following solutions:
[tex]\sin A_{1} \approx 2.618[/tex] and [tex]\sin A_{2} \approx 0.382[/tex]
Since sine is a bounded function between -1 and 1, the only solution that is mathematically reasonable is:
[tex]\sin A \approx 0.382[/tex]
By means of inverse trigonometrical function, we get the value associate of the function in sexagesimal degrees:
[tex]A \approx 22.457^{\circ}[/tex]
Then, the values of the cosine associated with that angle is:
[tex]\cos A \approx 0.924[/tex]
Now, we have that [tex]f(A) = \sin 2A +\csc2A[/tex], we proceed to transform the expression into an equivalent form with sines and cosines. The following trignometrical identities are used:
[tex]\sin 2A = 2\cdot \sin A\cdot \cos A[/tex] (4)
[tex]\csc 2A = \frac{1}{\sin 2A}[/tex] (5)
[tex]f(A) = \sin 2A + \csc 2A[/tex]
[tex]f(A) = \sin 2A + \frac{1}{\sin 2A}[/tex]
[tex]f(A) = \frac{\sin^{2} 2A+1}{\sin 2A}[/tex]
[tex]f(A) = \frac{4\cdot \sin^{2}A\cdot \cos^{2}A+1}{2\cdot \sin A \cdot \cos A}[/tex]
If we know that [tex]\sin A \approx 0.382[/tex] and [tex]\cos A \approx 0.924[/tex], then the value of the function is:
[tex]f(A) = \frac{4\cdot (0.382)^{2}\cdot (0.924)^{2}+1}{2\cdot (0.382)\cdot (0.924)}[/tex]
[tex]f(A) = 2.122[/tex]

The equation y = (x + 2)² + 3 represents the shown parabolic graph. The correct answer is option B.
The vertex of the parabola occurs at the point (-2, 3), which is the point where the parabola reaches its minimum value.
The term (x + 2)² indicates that the parabola is translated horizontally by 2 units to the left from the standard vertex form of a parabola.
The "+3" term indicates that the parabola is translated vertically by 3 units upward.
Hence, the equation y = (x + 2)² + 3 represents the shown parabolic graph.
Thus, the correct answer is option B.
