To go to a movie, a family with 2 adults and 4 children spends $64. A family containing 1 adult and 3 children spends $42. Find the cost of an adult movie ticket and the cost of a child movie ticket.
Answer:
all work is pictured and shown
The cost of a ticket for an adult is $12 while for children it is $10.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
Let's assume that cost for adults is A while for children it is C
Now,
2 adults and 4 children spend $64.
2A + 4C = 64
1 adult and 3 children spend $42.
A + 3C = 42
Multiply by 2
2A + 6C = 84
By subtracting equations
6C - 4C = 84 - 64
2C = 20
C = 10
A = 42 - 3(10)
A = 12
Hence "The cost of a ticket for an adult is $12 while for children it is $10".

solve for x. log10x=4
Final answer:
To solve the equation log10x = 4, we convert it to its exponential form, which is 10^4 = x. By doing the calculation, we find that x equals 10,000. This value is the inverse log of the number 4.
Explanation:
To solve the equation log10x=4, we need to understand that this is a common logarithmic equation where the base of the logarithm is 10. The equation essentially asks what power we must raise 10 to in order to get x. In this case, the power is 4.
According to the properties of logarithms, we can rewrite the equation in its exponential form which is 10^4 = x. So, x = 10,000.
This value of x is obtained by taking the inverse log of 4 or calculating 10^4 using a calculator, which yields the result 10,000. Therefore, x = 10,000 is the solution to the equation log10x = 4.
A cylinder and its dimensions are shown below.
12.1 cm
3.8 cm
One equation for calculating the volume of a cylinder is V=Bh, where 8 represents the area of the base of the cylinder. Which expression can be used to find the value of B, in square centimeters, for this cylinder?
A (12.1 B 2(12.1)
C (3.8)
D None of these
Answer:
[tex](A) B=\pi (12.1)^2[/tex]
Step-by-step explanation:
Given a cylinder with the following dimensions
Radius of the Cylinder =12.1 cm
Height of the Cylinder =3.8cm
Volume of a cylinder = Base Area X Height
The base area is a circle, therefore the expression that can be used to find the value of B, (in square centimeters), for this cylinder is given as:
[tex]Base Area =\pi r^2\\B=\pi (12.1)^2[/tex]
The correct option is A. (12.1) expression can be used to find the value of B, in square centimeters, for this cylinder.
To find the value of B, which represents the area of the base of the cylinder, we can use the formula for the volume of a cylinder, V = Bh, where V is the volume, B is the area of the base, and h is the height.
We are given the volume V = 12.1 cm³ and the height h = 8 cm.
We can rearrange the formula to solve for B:
[tex]\[ B = \frac{V}{h} \][/tex]
Substituting the given values:
[tex]\[ B = 1.5125 \text{ cm}^2 \][/tex]
Since the volume and height are both given in centimeters, the unit for B will be in square centimeters.
The expression that can be used to find the value of B is indeed the volume divided by the height, which simplifies to the given volume of 12.1 cm³ divided by the height of 8 cm, resulting in [tex]\( B = \frac{12.1}{8} \) or \( B = 1.5125 \).[/tex]
Therefore, the expression to find the value of B, in square centimeters, for this cylinder is [tex]\( B = \frac{12.1}{8} \),[/tex] which is option A. (12.1).

Complete question:
Find length of PR. TR=x+11
Step-by-step explanation:
In a square,
we know that when diagonals bisect each other it is divided into two equal parts
so
TR = TP
So
PR = x +11 + x + 11
= 2x + 22
And
Both diagonals are equal so
QS = PR
7x - 3 = 2x + 22
7x - 2x = 22 + 3
5x = 25
x= 25 /5
x = 5
Now
PR = 2 * 5 +22= 10 +22 = 32
Answer:
PR = 34
Step-by-step explanation:
The diagonals of a square bisect each other, and are congruent, thus
QS = PR, that is
7x - 8 = x + 11 + x + 11 = 2x + 22 ( subtract 2x from both sides )
5x - 8 = 22 ( add 8 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6
Thus
PR = 2x + 22 = 2(6) + 22 = 12 + 22 = 34

As part of a competition Diego must spin around in a circle six times and then run to a tree. The time he spends on each spin is represented by s and the time he spends running is r. He gets to the tree 21 seconds after he starts spinning. Write an equation showing the relationship between s and r.
Answer:
6s + 2r = 21
Step-by-step explanation:
Please kindly see the attached file for explanaion
The correct equation showing the relationship between s and r is 6s + r = 21
To derive this equation, we consider the total time Diego spends on the competition, which is the sum of the time he spends spinning and the time he spends running.
Since Diego spins around in a circle six times and each spin takes time s, the total time spent spinning is 6s
After spinning, he runs to the tree, which takes time r.
Therefore, the total time from the start of the spinning until Diego reaches the tree is the sum of the time spent spinning and running.
Given that Diego reaches the tree 21 seconds after he starts spinning, we can set up the following equation to represent this relationship:
6s + r = 21
This equation states that six times the time spent on each spin plus the time spent running equals 21 seconds.
Solving this equation for either s or r would give us the time spent on each activity, provided we know the total time of 21 seconds.
If the risk-free rate is 8 percent and the market risk premium is 2 percent, what is the required return for the market?
The required return for the market can be calculated using the Capital Asset Pricing Model (CAPM), which takes into account the risk-free rate, beta value, and market risk premium.
Explanation:The required return for the market can be calculated using the Capital Asset Pricing Model (CAPM). The CAPM formula is:
Required Return = Risk-Free Rate + Beta * Market Risk Premium
In this case, the risk-free rate is given as 8%, and the market risk premium is given as 2%. To calculate the required return for the market, we need to know the beta value, which represents the stock's sensitivity to market movements.
Once we have the beta value, we can substitute it into the formula to find the required return for the market.
Final answer:
The required return for the market, when the risk-free rate is 8 percent and the market risk premium is 2 percent, is 10 percent according to the Capital Asset Pricing Model.
Explanation:
The student is inquiring about the concept of the required return of the market, which is a fundamental concept in finance related to the Capital Asset Pricing Model (CAPM). According to CAPM, the required return on a market portfolio (the market) is the sum of the risk-free rate and the market risk premium. In this case, with an 8 percent risk-free rate and a 2 percent market risk premium, the required return for the market would be the sum of these two figures, which equals 10 percent.

Factor the following polynomial:
5x(a-b)-2y(a-b)
Answer:
(a - b)(5x - 2y)
Step-by-step explanation:
Given
5x(a - b) - 2y(a - b) ← factor out (a - b) from each term
= (a - b)(5x - 2y) ← in factored form
The polynomial 5x(a-b)-2y(a-b) can be factored into (a-b)(5x-2y). This is achieved by taking out the common factor of (a-b) from both terms.
Explanation:To factor the polynomial
5x(a-b)-2y(a-b)
, you first notice that the terms have a common factor, (a-b). Factoring is a process where you write the expression as a product of its factors. In this case, you can pull out the common factor from both terms. This leaves you with
(a-b)(5x-2y)
. So, the factored form of the given polynomial is (a-b)(5x-2y). By applying the distributive property, you can check your work: (a-b)*5x gives the first term and (a-b)*(-2y) gives the second term, confirming the factored form is correct.

Answer:
Step-by-step explanation:
It means there is no solution and the lines are parallel. It is called an inconsistent system.
I hope this helps
The system has no solution. Thus, the lines are parallel to each other.
The system of the equation has no solution. The expression leads to the value that is 0=4, which means you concluded the final result as 0=4.
Do you think practically it is possible, never, it is not possible to equate zero with four, same in the solutions of the system in the lines, this kind of results will not be taken by the intersecting lines.
Hence, the above expression is the condition for "No Solution"
If we try to evaluate the solution of the system that has no solution or an infinite number of solutions, then the variables are canceled out and only the constant values are left that are not equal.
