Answer:

the allocation of overhead to department A is $8,000.00

Step-by-step explanation:

Given that Department A had sales of $200,000.00 and Department B had sales of $600,000.00, the ratio of department A's sales to that of department B is 200,000.00 / 600,000.00 = 1/3.

The total overhead expenses were $32,000.00, the allocation of overhead to department A is  32,000.00 / (3 + 1) = $32,000.00 / 4 = $8,000.00

Answer:

[tex]f(x)=|x+4|+2[/tex]

Step-by-step explanation:

The given absolute value function is

[tex]f(x)=|x|[/tex]

This is the base or the parent function.

The transformation [tex]f(x)=|x+b|+c[/tex] will shift the parent function b units to the left and c units up.

From the question, b=4 units and c=2 units.

The new equation is [tex]f(x)=|x+4|+2[/tex]

Answer:  The equation of the new function is [tex]f(x)=|x+4|+2.[/tex]

Step-by-step explanation:  We are given to find the equation of the new function if we apply the following changes to the absolute value parent function f(x)=lxl :

Shift 4 units left   and  Shift 2 units up.

We know that

if we shift the absolute value parent function f(x) = |x| to h units left and k units up, then the new equation will be

[tex]f(x)=|x+h|+k.[/tex]

Therefore, if the function is shifted 4 units left and 2 units up, then the equation of the new function will be

[tex]f(x)=|x+4|+2.[/tex]

Thus, the equation of the new function is [tex]f(x)=|x+4|+2.[/tex]

Answer:

78°

Step-by-step explanation:

The angular distance of an arc is twice the angle that forms it if that angle lies of the edge of the circle.

By this, Arc AK has angular distance 158°.

Arc JL = 202°.

Arc KL = 122°.

By subtracting these we get 80° for Arc JK.

Arc KA = 158°.

Arc AJ = KA - JK

AJ = 158-80

AJ = 78°

Answer:

the answer is D.  576 square cm

Step-by-step explanation:

Find the area of one of the rectangular faces using the formula, Area = lw.

A = (12 cm) (6 cm)

A = 72 square cm

Since there are 4 rectangular faces, multiply the area of one rectangular face by 4 to get a total of 288 square cm.

The area of one of the congruent squares is 12 cm × 12 cm, or 144 cm2. Multiply 144 cm2 by 2 to get a total of 288 cm2.

To find the surface area of the rectangular prism, add the area of the four rectangular faces to the area of the two square faces.

288 square cm + 288 square cm = 576 square cm

Answer:

6

Step-by-step explanation:

cause we will add them together

5x -1 = 3x +11

2x=12

x=6

The value of x if ∠3 = 5x - 1, and ∠5 = 3x + 11, is 6.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively.

Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles.

Given;

∠3 = 5x - 1, and ∠5 = 3x + 11,

Calculate the value of x as shown below,

∠3 = ∠5  (Alternate interior angles between parallel lines are equal)

5x - 1 = 3x + 11

5x - 3x = 11 + 1

2x = 12

x = 12 / 2

x = 6

Thus, the value of x is 6.

B:  The salaries

Step-by-step explanation:

B:  The salaries.  While not strictly continuous, the range of salaries is closest of these four choices to being continuous.  In contract, "number of employees," "number of printers," and "number of phone calls" are all discrete random variables.

The statement at D "The number of phone calls made daily from an office" is a continuous random variable.

A random variable is defined for all the values in an interval or between two values.

A. The number of employees in an office.

It is a constant value. It's not a continuous random variable.

B. The salaries of employees in an office

It is a constant value. It has only one value means represented in a closed interval. So, not a continuous random variable

C. The number of printers in an office

This is also a constant value. So, not a continuous random variable

D. The number of phone calls made daily from an office

The number of phone calls made daily, may not be the same and are continuous. If the interval of a month, there may be a different number of phone calls. So, it is a continuous random variable.

So, option D is correct.

Answer:

- 1/5

Step-by-step explanation:

Slope of a line passing through two points can be calculated as:

[tex]\text{slope}=\frac{\text{rise}}{\text{run}} \\\\ \text{slope}=\frac{\text{Difference of y coordinates}}{\text{Difference of x coordinates}}[/tex]

The given points are (-2, -1) and (8, -3). Using the values in above formula, we get:

[tex]\text{slope}=\frac{-3-(-1)}{8-(-2)}\\\\ \text{slope}=\frac{-3+1}{8+2}\\\\ \text{slope}=\frac{-2}{10}\\\\ \text{slope}=\frac{-1}{5}[/tex]

Thus the slope of the line through the given points is -1/5. So 2nd option gives the correct answer

Answer:

The correct answer is second option

-1/5

Step-by-step explanation:

Points to remember

The slope of line passing through (x₁, y₁) and (x₂, y₂) is given by,

Slope = (y₂ - y₁)/(x₂ - x₁)

To find the slope of given line

Here, (x₁, y₁) = (-2, -1) and (x₂, y₂) = (8, -3)

Slope = (y₂ - y₁)/(x₂ - x₁) = ( -3 - - 1)/(8 - -2)

 = (-3 + 1)/(8 + 2) = -2/10

 = -1/5

Therefore the correct answer is second option -1/5

Average Rate of Change

[tex] = \frac{f(b) - f(a)}{b - a} [/tex]

EXPLANATION

To find the average rate of change of y=f(x) from x=a to x=b means finding the slope of the secant line joining the points

(a,f(a)) and (b,f(b))

The slope of the secant line joining these points is

[tex] = \frac{f(b) - f(a)}{b - a} [/tex]

This gives the average rate of change of the function.

To find the average rate of change of a function, you need to subtract the function values at two different points and divide by the difference in the input values.

To find the average rate of change of a function, you need to calculate the change in the function's output divided by the change in its input. This can be done by subtracting the function values at two different points and dividing by the difference in the input values. For example, if you have a function f(x) and want to find the average rate of change between x = a and x = b, you would use the formula:

Average Rate of Change = (f(b) - f(a)) / (b - a)

This will give you the average rate at which the function is changing over the interval from a to b.

#SPJ1

In a thirty-year fixed-rate mortgage, the principal portion of the payment is the same amount each time it is paid, while the interest decreases over time, thus maintaining a consistent total payment amount.

The student is asking which of the following payments is the same amount each time it is paid: Property Taxes, PMI (Private Mortgage Insurance), Interest, or Principal. The answer is Principal in the context of a thirty-year fixed-rate mortgage.

This type of mortgage has a consistent monthly payment that includes both the principal and the interest. Early in the loan, the payment consists of more interest than principal, but as the loan matures, the portion of the payment that goes towards the principal increases while the interest portion decreases.

This ensures that the total payment amount remains the same throughout the life of the loan.

Example of Principal Payment Over Time

If you have a thirty-year fixed-rate mortgage, your monthly payment is calculated at the outset to ensure that each payment is the same, even though the principal paid increases over time as the outstanding balance of the loan decreases.

Answer:

sin(62)=18/x

Step-by-step explanation: sine = opp/hyp

Answer: Third option.

Step-by-step explanation:

Given the right triangle in the figure attached, you know that, for the known angle of 62 degrees, the lenght of the opposite side is 18 and the hypotenuse is "x"

[tex]sin\alpha=\frac{opposite}{hypotenuse}[/tex]

Then, having that:

[tex]\alpha=62\°\\opposite=18\\hypotenuse=x[/tex]

 You need to substitute these values into  [tex]sin\alpha=\frac{opposite}{hypotenuse}[/tex], then  you get that the correct trigonometry formula to use to solve for "x" is:

Answer:

Finance charge =  $2.32

new balance = $201.51

Step-by-step explanation:

Finance charge = Previous balance×Periodic percentage rate

The previous balance is 199.19

The annual percentage rate is 0.14. Therefore, the periodic percentage rate is; (0.14/12)

Finance charge = 199.19 * (0.14/12)

                           = 2.3239 = $2.32

new balance = previous balance + finance charge

                      = 199.19 + 2.32

                      = $201.51

Solution:

Let t = working together in terms of days

(1/4) + (1/12) = 1/t
