Answer:

A. A lively accompaniment

Step-by-step explanation:

B. Dissonant - would most likely result in a eerie mood

C. A slow tempo - could result in melancholy or calm emotions

D. A minor key - could also result in melancholy emotions

Step-by-step explanation:

0.25c = 63.25

We would just get c alone by dividing by 0.25 on both sides of the equal sign

c = 253

Answer: C = 253

Step-by-step explanation:

Based on the given data, the distance from center to center of two consecutive holes is approximately 25.83 inches.

To solve this problem, we need to divide the length of the metal strip (excluding the 2 inches on each end) by the number of holes to be drilled, and that will give us the distance from center to center of two consecutive holes.

So the length of the metal strip available for the 12 holes is:

3414 - 2 - 2 = 3410 inches

Dividing this length by the number of holes gives us:

3410 ÷ 12 = 284.166666... inches

To find the distance from center to center of two consecutive holes, we need to divide this value by the number of spaces between the holes, which is 11 (since there are 12 holes, but only 11 spaces between them). So:

284.166666... ÷ 11 = 25.833333...

Rounding this to the nearest hundredth of an inch, we get:

25.83 inches (to the nearest hundredth)

Therefore, the distance from center to center of two consecutive holes is approximately 25.83 inches.

Answer: To calculate the total cost of the units in beginning inventory for each year, we need to multiply the number of units by the per-unit cost:

Year 1: Cost of units in beginning inventory = 0 units * $13 + $5 + $5 = $0

Year 2: Cost of units in beginning inventory = 1,000 units * ($13 + $5 + $5) = 1,000 * $23 = $23,000

To calculate the total cost of the units produced during each year, we need to multiply the number of units by the per-unit cost:

Year 1: Cost of units produced = 10,000 units * ($13 + $5 + $5) = 10,000 * $23 = $230,000

Year 2: Cost of units produced = 9,000 units * ($13 + $5 + $5) = 9,000 * $23 = $207,000

To calculate the total cost of the units sold during each year, we need to multiply the number of units sold by the per-unit cost:

Year 1: Cost of units sold = 9,000 units * ($13 + $5 + $5 + $6) = 9,000 * $29 = $261,000

Year 2: Cost of units sold = 8,000 units * ($13 + $5 + $5 + $6) = 8,000 * $29 = $232,000

To calculate the total variable manufacturing costs for each year, we need to sum the costs of the units in beginning inventory, units produced, and units sold:

Year 1: Total variable manufacturing costs = $0 + $230,000 + $261,000 = $491,000

Year 2: Total variable manufacturing costs = $23,000 + $207,000 + $232,000 = $462,000

To calculate the total fixed manufacturing overhead costs for each year, we need to add the fixed manufacturing overhead per year to the total variable manufacturing costs:

Year 1: Total manufacturing costs = $491,000 + $90,000 = $581,000

Year 2: Total manufacturing costs = $462,000 + $90,000 = $552,000

To calculate the total variable selling and administrative expenses for each year, we need to multiply the number of units sold by the variable selling and administrative expense per unit:

Year 1: Total variable selling and administrative expenses = 9,000 units * $6 = $54,000

Year 2: Total variable selling and administrative expenses = 8,000 units * $6 = $48,000

To calculate the total selling and administrative expenses for each year, we need to add the fixed selling and administrative expenses per year to the total variable selling and administrative expenses:

Year 1: Total selling and administrative expenses = $54,000 + $61,000 = $115,000

Year 2: Total selling and administrative expenses = $48,000 + $61,000 = $109,000

Step-by-step explanation:

Using the system of equations, we found the number of adult tickets sold as 82 and the number of child tickets sold as 42.

What is the system of equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

Given,

Number of tickets sold = 124

Cost of one adult ticket = $ 12.50

Cost of one child ticket = $ 6.50

Total money received = $ 1298

We can write a system of equations using the above information.

Number of adult tickets sold = x

Number of child tickets sold = y

x + y = 124

12.5x + 6.5y = 1298

Solving the above equations, we can find x and y.

Multiplying the first equation by 6.5

6.5x+ 6.5y = 806

12.5x + 6.5y = 1298

Subtracting the equations,

-6x = -492

x = 82

Substituting the above value in any one of the equation

82 + y = 124

y = 42

Therefore from the system of equations, the number of adult tickets sold is 82 and the number of child tickets sold is 42.

If a rectangular room is 2 meters longer than it is wide, and its perimeter is 24 meters then the  dimensions of the room: 7 meter x 5 meter

Perimeter is a mathematical term, it indicates total outer boundary of a figure, we define it only for two dimensional figures.

Perimeter = Sum of length of the all the sides

Let x be the width of the room in meters.

Then the length of the room is 2 meters longer, which means it is x+2 meters.

In this case, we know that the perimeter is 24 meters.

So we can set up an equation:

Perimeter = 2Length + 2Width

Substituting the values we know:

24 = 2(x+2) + 2x

Simplifying the equation:

24 = 2x + 4 + 2x

24 = 4x + 4

20 = 4x

x = 5

So the width of the room is 5 meters, and the length is x+2 = 7 meters.

Here's how the long division would look like:

x³ - 4x² - 3x + 18

       ÷ x + 2

__________________________

x² - 6x - 20

             ÷ x + 2

__________________________

x - 22

       ÷ x + 2

__________________________

-20

Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.

The formula for calculating Compound Interest is

A = P ( 1 + r/n )ⁿᵇ

where A = Final Amount

P = Principal

r = rate of interest

n = number of times interest is applied

b = number of time periods elapsed

Given data ,

Answer:

To solve this problem, we can use the formula for exponential growth:

V(t) = V0 * (1 + r)^t

where:

V(t) is the value of the equipment at time t

V0 is the initial value of the equipment ($15,000)

r is the annual growth rate (15.9% or 0.159)

t is the time in years

We want to find the time t when the value of the equipment will be less than $7500. So we can set up the following inequality:

V(t) < 7500

Substituting the formula for V(t), we get:

V0 * (1 + r)^t < 7500

Substituting the given values, we get:

15000 * (1 + 0.159)^t < 7500

Simplifying and solving for t,

we get:(1 + 0.159)^t < 0.5

t * log(1 + 0.159) < log(0.5)

t > log(0.5) / log(1 + 0.159)

The equation which is in the quadratic form is 6x⁴ + 7x² - 3 = 0. So Option B is correct.

An equation is quadratic in form if it can be written in the form of ax + bx + c = 0, where a, b, and c are constants and x is the variable.

Among the given equations, we can see that the first, third, and fourth equations are not quadratic in form, since they contain x raised to powers other than 2.

The second equation, 6x⁴ + 7x² - 3 = 0, can be written in quadratic form by making a substitution.

If we let y = x², then we can write the equation as 6y² + 7y - 3 = 0,
