If 2k +3,3k - 1,5k - 3 are in an AP, find the three terms.
Answers
Answer:
Step-by-step explanation:
First term = 2k +3
Second term = 3k - 1
Third term = 5k - 3
As, it is AP,
Second term - first term = Third term - Second term
3k - 1 - (2k + 3) = 5k -3 - (3k -1)
3k - 1 - 2k -3 = 5k - 3 - 3k + 1
3k - 2k - 1 - 3 = 5k - 3k - 3 + 1
Combine like terms
1k - 4 = 2k -2
Add '2k' to both sides
k - 2k -4 = -2
-k - 4 = - 2
Add 4 to both sides
-k = -2 +4
-k = 2
Multiply both sides by (-1)
k = 2 * (-1)
k = -2
2k + 3 = 2*(-2) + 3 = -4 +3 = -1
3k - 1 = 3*(-2) - 1 = -6 - 1 = -7
5k - 3 = 5*(-2)- 3 = -10 - 3 = -13
Skyler is buying wings and quesadillas for a party. A package of wings costs $8.00. A package of quesadillas cost $10.00. He must spend no more than $160.00. Skyler's freezer will hold a maximum of 20 packages of wings and quesadillas. Write a system of linear inequalities to represent the situation.
Answers
Answer:
The system of inequalities are;
q + w ≤ 20
8w + 10q ≤ 160
Step-by-step explanation:
Let the number of wigs be w and the number of quesadillas be q
Since we have a maximum of 20 packages;
then;
q + w ≤ 20
Let’s now work with the prices
price of w wings is 8 * w =$8w
price of q quesadillas is 10 * q = 10q
The maximum amount to spend is $160
Thus, the addition will be;
8w + 10q ≤ 160

B
T ? Which one will have a greater γ ? Which one will have a greater D (where D refers to the diffusion constant not diameter)? Justify your reasoning for each case.
Answers
(a) Both particles have the same value of k_B T.
(b) The smaller particle has a greater value of γ.
(c) The smaller particle has a greater value of D.
a) To show γD = k_B T, we start with the given relations:
⟨v0,x^2⟩ = (Δt/L)^2
γ = Δt/(2m)
D = (2Δt)/(L^2)
Substituting the expression for γ into the equation for D:
D = (2Δt)/(L^2) = (2Δt)/(L^2) * Δt/(2m) = (Δt^2)/(mL^2) = γ^2/m
Now, multiplying γ and D:
γD = γ * D = γ^2/m = (Δt/(2m))^2/m = Δt^2/(4m^2) = (1/4m) * (Δt^2/m) = (1/4m) * γ = (1/4m) * (Δt/(2m)) = (k_B T)/(4m)
Since k_B T is the average kinetic energy per degree of freedom and (1/4m) is the average kinetic energy per particle, we can equate γD and k_B T:
γD = k_B T
b) The dependence of γD on m is 1/m. As we can see from the equation γD = (k_B T)/(4m), as the mass (m) increases, the value of γD decreases.
c) When comparing two spherical particles in the same solution:
Greater value of k_B T: Both particles will have the same value of k_B T since it depends on temperature (T) and is independent of the size or mass of the particles.
Greater value of γ: The smaller particle will have a greater value of γ. As γ = Δt/(2m), since the mass of the smaller particle is smaller, the value of γ will be greater.
Greater value of D: The smaller particle will have a greater value of D. As D = (2Δt)/(L^2), since the time between collisions (Δt) will be smaller for the smaller particle due to its faster movement, the value of D will be greater.

Answers
According to the statement the labour cost is $393 (Type an integer or a decimal rounded to two decimal places.) or simply $393.
Given information:Labour content in the production of an article is 16 2/3% of total cost.
Total cost is $456
To find:The labour costSolution:Labour content in the production of an article is 16 2/3% of total cost.
In other words, if the total cost is $100, then labour cost is $16 2/3.
Let the labour cost be x.
So, the total cost will be = x + 16 2/3% of x
According to the question, total cost is 456456 = x + 16 2/3% of xx + 16 2/3% of x = $456
Convert the percentage to fraction:16 \frac{2}{3} \% = \frac{50}{3} \% = \frac{50}{3 \times 100} = \frac{1}{6}
Therefore,x + \frac{1}{6}x = 456\Rightarrow \frac{7}{6}x = 456\Rightarrow x = \frac{456 \times 6}{7} = 393.14$
So, the labour cost is $393.14 (Type an integer or a decimal rounded to two decimal places.)
The labour cost is $393 (Type an integer or a decimal rounded to two decimal places.) or simply $393.

1. The product of 1.35 m and 2.467 m is 3.3 m².
2. The product of 1.4267 × 10² m and 1.278 × 10³ m is 1.8 × 10⁶ m².
1. When multiplying numbers, the rule for significant figures is to count the number of significant figures in each factor and use the smaller count as the significant figures in the result.
In this case, both 1.35 m and 2.467 m have three significant figures each, so the result should be expressed with three significant figures as well. The multiplication gives us 3.33345 m², but since we can only have three significant figures, we round it to 3.3 m².
2. The product of 1.4267 × 10² m and 1.278 × 10³ m is 1.8 × 10⁶ m².
To multiply numbers in scientific notation, we multiply the coefficients and add the exponents. In this case, multiplying 1.4267 and 1.278 gives us 1.8259306.
When we multiply the powers of 10 (10² and 10³), we add the exponents, resulting in 10⁵.
Combining these results, we get 1.8259306 × 10⁵ m². However, since we need to express the answer with the correct number of significant figures, we round it to 1.8 × 10⁶ m², as there is only one significant figure in the given data.

jeff paid $4773 for 6 identical printers and 3 identical cameras. ron bought 4 such printers and 6 such cameras and paid $5002 in all. what is the cost of each printer?
Answers
The cost of each printer is $568.
Find cost per unitTo find the cost of each printer, we need to use a system of equations.
Let's call the cost of each printer "p" and the cost of each camera "c".
The first equation we can create is: 6p + 3c = 4773
The second equation we can create is: 4p + 6c = 5002
Now we can use the elimination method to solve for one of the variables.
Let's eliminate the "c" variable by multiplying the first equation by -2: -12p - 6c = -9546
And then add the two equations together: -8p = -4544
Now we can solve for "p" by dividing both sides by -8: p = 568
So the cost of each printer is $568.
To find the cost of each camera, we can plug the value of "p" back into one of the original equations and solve for "c":
6(568) + 3c = 4773
3408 + 3c = 4773
3c = 1365
c = 455
So the cost of each camera is $455.
Therefore, the cost of each printer is $568 and the cost of each camera is $455.

Answers
The school’s band members sold 40 shirts and 40 magazine subscriptions.
What is an equation?A statement of equality between two expressions made up of variables and/or integers is called an equation. In essence, equations are questions, and the reason for the advancement of mathematics has been the systematic search for the answers to these questions.
Given:
profit per shirt = $5
set up costs = $40
profit per magazine = $4
Let us assume S = shirts, C = setup costs, M = magazine
So, we can write the equation
5S - C = 4M
The profit from shirts and magazines are same. So, S = M
5S - 40 = 4S
5S - 4S = 40
S = 40

Answers
Given:
Short sides of a rectangle = 2 inches.
Area of the rectangle = 22 square inches.
The long sides of the same rectangle are three less than an unknown number of inches.
To find:
The unknown number.
Solution:
Let x be the unknown number. Then the longer side of the rectangle is (x-3) inches.
We know that the area of a rectangle is
\(A=length\times width\)
The area of the rectangle is 22 square inches.
\(22=2(x-3)\)
Divide both sides by 2.
\(11=x-3\)
Add 3 on both sides.
\(11+3=x-3+3\)
\(14=x\)
Therefore, the value of the unknown number is 14.
