Navern Corporation's manufacturing cycle efficiency (MCE) for its elevators is approximately 11.36%.
How to calculate the valueValue-added time is the time spent on activities that directly add value to the product.
Value-added time: Process time = 5 days (the process of manufacturing the elevators)
Total cycle time: Wait time + Inspection time + Process time + Move time + Queue time
= 12 days + 12 days + 5 days + 6 days + 9 days
= 44 days
MCE = (Value-added time / Total cycle time) * 100
= (5 days / 44 days) * 100
≈ 11.36%
Therefore, Navern Corporation's manufacturing cycle efficiency (MCE) for its elevators is approximately 11.36%.

(1) The full payment required on January 22 to reduce the balance on the invoice to zero is $136,294.57.
(2)The full payment required on October 19 to reduce the balance on the invoice to zero is $98,482.75.
(3)The full payment required on April 3 to reduce the balance on the invoice to zero is $48,190.38.
The calculation of the full payment required takes into account the terms specified on the invoice. In the first scenario, the invoice terms are 2/10, n/30, which means that a 2% discount can be applied if payment is made within 10 days, otherwise, the full payment is due within 30 days.
Therefore, the full payment is calculated as the invoice amount minus the discount. Similarly, for the second scenario, the invoice terms are 3/10, 2/20, 1/30, and n/50, which involve multiple discounts based on different payment dates.
The full payment is determined by applying the applicable discounts. Finally, in the third scenario, the invoice terms are ROG (Receipt of Goods), and the full payment is due by April 15. Hence, the full payment required on the specified date is calculated.

Step-by-step explanation: A is not a subset of E.
However, E is a subset of A
find all the values of c such that the distance from the point (x,8) to the point (2,-4) is exactly 13 units give answer in ascending order
Therefore, the values of c are 2 + 5 = 7 and 2 - 5 = -3. So, the values of c that satisfy the condition are -3 and 7.
To find the values of c such that the distance from the point (x,8) to the point (2,-4) is exactly 13 units, we can use the distance formula.
The distance formula between two points (x₁, y₁) and (x₂, y₂) is given by:
√((x₂ - x₁)² + (y₂ - y₁)²)
In this case, we have (x₁, y₁) = (x, 8) and (x₂, y₂) = (2, -4). Substituting these values into the distance formula, we get:
√((2 - x)² + (-4 - 8)²) = 13
Simplifying, we have:
√((2 - x)² + (-12)²) = 13
Squaring both sides of the equation to eliminate the square root, we get:
(2 - x)² + (-12)² = 13²
Expanding and simplifying:
(x - 2)² + 144 = 169
(x - 2)² = 169 - 144
(x - 2)² = 25
Taking the square root of both sides, we have:
x - 2 = ±5
Solving for x, we get:
x = 2 ± 5

if f(x)= 1 over 9x -2, what is f^-1(x)?
Therefore, the inverse function f^(-1)(x) of f(x) = 1/(9x - 2) is f^(-1)(x) = (2x + 1)/(9x).
To find the inverse function of f(x) = 1/(9x - 2), denoted as f^(-1)(x), we follow these steps:
Replace f(x) with y: y = 1/(9x - 2).
Swap the variables x and y: x = 1/(9y - 2).
Solve the equation for y. Begin by multiplying both sides of the equation by (9y - 2): x(9y - 2) = 1.
Distribute the x on the left side: 9xy - 2x = 1.
Add 2x to both sides: 9xy = 1 + 2x.
Divide both sides by 9x: y = (1 + 2x)/(9x).

(x+6/7)^2+(y+4)^2=49/4 find three points of this circle
To find three points on the circle defined by the equation (x+67)2+(y+4)2=494(x+76)2+(y+4)2=449, we can manipulate the equation to extract the center and radius information.
Expanding the equation, we have:
x2+127x+3649+y2+8y+16=494x2+712x+4936+y2+8y+16=449
Combining like terms, we get:
x2+y2+127x+8y+1149=0x2+y2+712x+8y+4911=0
Comparing this equation to the standard form of a circle, (x−a)2+(y−b)2=r2(x−a)2+(y−b)2=r2, we can identify the center (a,b)(a,b) as −67,−4−76,−4 and the radius rr as 7227.
Now we can find three points on the circle by substituting different angles into the equation. For example:
At 00 degrees: (−6/7+72),−4(−6/7+27),−4 or (11/14,−4)(11/14,−4)
At 9090 degrees: −6/7,−4+72−6/7,−4+27 or −6/7,1/2−6/7,1/2
At 180180 degrees: (−6/7−72),−4(−6/7−27),−4 or (−55/14,−4)(−55/14,−4)
Therefore, three points on the circle are (11/14,−4)(11/14,−4), (−6/7,1/2)(−6/7,1/2), and (−55/14,−4)(−55/14,−4).

It will cost $1080 to paint all the interior surfaces of the pool.
6. & 7. The triangles have sides of 8, 8, and 10 cm, and an area of 24 square cm. The remaining areas are 18 and 12 square cm, respectively.
Triangle with Sides 8, 8, and 10 cm: First, we must calculate the area of the whole triangle, which has sides of 8, 8, and 10 cm. Using the Heron's formula, we can find the area of a triangle given the lengths of its sides: A = √(s(s - a)(s - b)(s - c)), where s = (a + b + c)/2 is the semi perimeter of the triangle.
A = √(13(13 - 8)(13 - 8)(13 - 10)) = √(13(5)(5)(3)) = √(2925) = 15√(65) ≈ 59.17 square cm. Next, we can calculate the areas of the shaded regions as follows: Area of Shaded Region 1 = Area of Whole Triangle - Area of Small Triangle Area of Shaded Region 1 = 15√(65) - 18 = 15√(65) - 6√(65) = 9√(65) ≈ 27.94 square cm.
Area of Shaded Region 2 = Area of Whole Triangle - Area of Large Triangle Area of Shaded Region 2 = 15√(65) - 24 = 3√(65) ≈ 7.74 square cm.7.
A swimming pool has the dimensions 8 m (length), 6 m (width), and 1.5 m (depth). The total area to be painted is the sum of the areas of the floor, the ceiling, and the walls of the pool. Since the pool is rectangular in shape, we can break it down into six different parts: the top and bottom surfaces, and the four vertical surfaces.
Let's begin by calculating the area of the floor, which has dimensions of 8 m by 6 m:Area of Floor = length x width = 8 x 6 = 48 square meters.
Next, we can calculate the area of the ceiling, which has the same dimensions as the floor: Area of Ceiling = length x width = 48 square meters. Since the pool has a depth of 1.5 m, the total height of the vertical surfaces is 1.5 x 2 = 3 m (since there are two vertical surfaces on each side of the pool).
Thus, the total area of the four vertical surfaces is given by: Area of Walls = perimeter x height = 2(length + width) x height = 2(8 + 6) x 3 = 84 square meters.
Finally, we can calculate the total area to be painted by adding up the area of the floor, ceiling, and walls: Total Area = Area of Floor + Area of Ceiling + Area of Walls Total Area = 48 + 48 + 84 = 180 square meters.
The cost of paint is given as $6 per square meter, so we can calculate the total cost of painting the pool as follows: Cost = Total Area x Cost per Square Meter Cost = 180 x $6 = $1080. Therefore, it will cost $1080 to paint all the interior surfaces of the pool.

A cook has 6 onions that have a total mass of 900 grams and 8 apples that have a total mass of 1 kilogram. All onions are the same size, and all apples are the same size. Which has the greater mass, an onion or an apple? Explain.
1. Underline the question you need to answer.
See above
2. What units are used in the problem?
The units used are grams and kilograms.
3. What should you do before comparing the masses?
Before comparing masses you should make sure that the apples and onions unit's are both the same.
4. How many kilograms is 900 grams?
0.9 kilograms
---
This is solved by creating a proportion:
Proportion is a mathematical comparison between two ratios (or fractions) and are equal to each other.
We know that 1 kilogram = 1000 grams
You can remember this by the fact that the prefix kilo = 1000
Your proportion would be set up as:
1 kilogram/ 1000 grams = x kilograms/ 900 grams
we can multiply 900 grams on both sides to isolate x (get x by itself)
900 grams * 1 kilogram/ 1000 grams = 900 grams * x kilograms/ 900 grams
simplified it would look like:
900 kg/1000 = x kg
x = 0.9 kg
So 0.9 kilograms is equal to 900 grams.
---
5. How many grams is 1 kilograms?
There are 1000 grams in 1 kilograms.
6. What do you need to do find the mass of 1 onion and 1 apple? Explain.
To find the mass of one onion you must divide the total mass of onions (900 grams) by 6, and you get that one onion is equal to 150 grams. To find the mass of one apple you can first convert its total mass (1 k) to grams, which equals 1000 grams. Now you can take its total mass in grams and divide it by 8. You get that one apple is equal to 125 grams.
Which has the greater mass, an onion or an apple? Explain
An onion has a greater mass than the apple because one onion has mass of 150 grams, which is greater than one apple's mass of 125 grams.

If don has three more than three times the number of marbles mark how many does each boy have to sell if the total number of marbles is 99 
Answer:
Don has 75 marbles to sell, Mark has 24 marbles to sell
Step-by-step explanation:
Don has three more than three times the number of marbles Mark has
Now this information can be put into equation form
(In this equation, D = Don and M = Mark)
Equation:
D = 3M + 3
The total number of marbles is 99
This represented as an equation is:
D + M = 99
Now, with both of these equations, it is now a system of equations. Now you must solve the system of equations.
Substitute the value of D from the first equation into the second equation
(3M + 3) + M = 99
4M + 3 = 99
4M = 99 - 3
4M = 96
M = 96/4
M = 24
Now you can substitute the value of M back into the first equation to find the value of D
D = 3(24) + 3
D = 72 + 3
D = 75
This shows that Don has 75 marbles to sell, and Mark has 24.

(2x + 3)2 = 81
Answer: x = 3 and x = -6
Step-by-step explanation:
the first step is to square root both sides of the equation to get rid of the exponent (2) on the left side of the equation, however lets break it down:
[tex](2x + 3)^2 = 81\\\\[/tex]
81 can be rewritten as 9^2
[tex](2x + 3)^2= 9^2[/tex]
and now lets square root both sides:
[tex]\sqrt{(2x+3)^2} =\sqrt{9^2}[/tex]
The squares (the exponent 2) cancels out with the square root:
2x + 3 = +/- 9
now lets isolate x by subtracting 3 from both sides:
2x + 3 = +/- 9
-3 -3
2x = -3 +/- 9
2x = -3 + 9
2x = 6
2x = -3 - 9
2x = 12
And after simplifying, you can divide two on both sides:
2x = 6
/2 /2
x = 3
2x = -12
/2 /2
x = -6
x = 3 and x = -6
Given that ABCDEF, solve for x.
A. 3
B. 2
OC. 6
D. 4
The value of side length x (DF) in the triangle is 4.
What is the value of x?The figures in the image is that of two similar triangle.
Triangle ABC is similar to triangle DEF.
From the diagram:
Leg 1 of the smaller triangle DE = 5
Leg 2 of the smaller triangle DF = x
Leg 1 of the larger triangle AB = 30
Leg 2 of the larger triangle AC = 24
To find the value of x, we take the ratio of the sides of the two triangle since they similar:
Hence:
Leg DE : Leg DF = Leg AB : Leg AC
Plug in the values:
5 : x = 30 : 24
5/x = 30/24
Cross multiplying, we get:
30x = 5 × 24
30x = 120
x = 120/30
x = 4
Therefore, the value of x is 4.

(2x-3)(5x squared-2x+7
Answer: [tex]10x^3-19x^2+20x-21[/tex]
Step-by-step explanation:
This problem is a binomial being multiplied by a trinomial.
We can solve it by multiply each term in the first expression by each term in the second expression and combine like terms.
[tex](2x - 3)(5x^2 -2x + 7)[/tex]
First lets multiply the 2x to the trinomial, (5x^2 - 2x + 7)
2x * 5x^2 = 10x^3
2x * -2x = -4x^2
2x * 7 = 14x
Next lets multiply the -3 to the trinomial (5x^2 - 2x + 7)
-3 * 5x^2 = -15x^2
-3 * -2x = 6x
-3 * 7 = -21
Now put all in order by highest power (Exponent) to lowest (to lowest exponent/ or constant)
[tex]10x^3-4x^2-15x^2+14x+6x-21[/tex]
And lastly, combine like terms:
[tex]10x^3-19x^2+20x-21[/tex]
Your final answer is [tex]10x^3-19x^2+20x-21[/tex]

Answer:
The interval from -12 to -7
The interval from 6 to 12.
Step-by-step explanation:
The equation is log(x + 9) + log(x 9) = log[(x + 9)(x 9)]. = log(x² − 81)
Here is the equation:
log(x² - 81) = 0.47712
This can be expressed in exponential form:
x² - 81 = 10^(0.47712)
x² = 81 + 3.02343
x² = 84.02343
x ≈ ± 9.1658
The answers are therefore x -9.1658 and x 9.1658.
These intervals are where these solutions occur:
The answer, x -9.1658, can be found in the range from -12 to -7.
- The answer x = 9.1658 is found in the range of 6 to 12.
The appropriate choices are:
- The range between -7 and -12; - The range between 6 and 12.

Answer:
(a) To find the mean of the data set, sum up all the values and divide by the total number of values.
44 + 44 + 54 + 54 + 65 + 39 + 54 + 44 = 398
Mean = 398 / 8 = 49.75
Rounded to one decimal place, the mean of this data set is 49.8.
(b) To find the median of the data set, i need to arrange the values in ascending order first:
39, 44, 44, 44, 54, 54, 54, 65
The median is the middle value in the sorted data set. In this case, we have 8 values, so the median is the average of the two middle values:
(44 + 54) / 2 = 98 / 2 = 49
Rounded to one decimal place, the median of this data set is 49.0.
(c) To determine the modes of the data set, identify the values that appear most frequently.
In this case, the mode refers to the value(s) that occur(s) with the highest frequency.
From the data set, i see that the value 44 appears three times, while the value 54 also appears three times. Therefore, there are two modes: 44 and 54.

Mushrooms have a yield factor of 90%. A 15 pound flat of mushrooms cost $29.85. What is the ap,cost per pound?
Answer: $2.21
Step-by-step explanation:
To calculate the cost per pound of mushrooms, we need to use the yield factor given in the question. The yield factor tells us the percentage of the total weight of the mushrooms that can be used for cooking or sale. Here, the yield factor is 90%, which means that 90% of the weight of the mushrooms can be used. Let's begin with the calculation:
First, we need to find out how much of the weight of the mushrooms is usable: 90% of 15 pounds = 0.9 x 15 = 13.5 pounds
Now, we can find out the cost per pound of the mushrooms:
Cost per pound = Total cost / Total usable weight
Total cost = $29.85
Total usable weight = 13.5 pounds
Therefore, the cost per pound of mushrooms = $29.85 / 13.5 pounds ≈ $2.21 per pound
Therefore, the cost per pound of mushrooms is $2.21 per pound.
100 Points! Geometry question. Determine whether each pair of triangles is similar. If so, write a similarity statement. If not, what would be sufficient to prove the triangles similar? Explain your reasoning. Photo attached. Thank you!
Answer:
Yes; TSU ~ PJM
Step-by-step explanation:
Because the angle in between the sides are the same, we can see if each corresponding side is proportional to each other. If they are, then they are similar. (This is SAS similarity theorem)
First we can divide 10 by 15 and see if 14 divided by 21 is the same:
10/15 = 0.6666....
14/21 = 0.6666....
Yes, the two triangles are similar
Answer:
Δ STU [tex]\bold{\sim}[/tex] ΔPJM similar
Step-by-step explanation:
Similar triangles are two or more triangles that have the same shape, but their sides are in proportion. In other words, if you divide the length of any side of one triangle by the corresponding side of another triangle, you will get the same number.
For Question:
In Δ STU and ΔPJM
TS:US =10:14=5:7
PJ: JM=15:21= 5:7
Since the length of any side of one triangle is by the corresponding side of another triangle, you will get the same number.
Therefore,
Δ STU [tex]\bold{\sim}[/tex] ΔPJM is similar.

what is the equasion for this line
The equation of the line in the graph that passes through (0,1) and (4,0) is [tex]y = -\frac{1}{4}x + 1[/tex].
What is the equation of the line?The equation of line is expressed as:
y = mx + b
Where m is slope and b is the y-intercept.
From the image, the graph passes through points (0,1) and (4,0).
First, we calculate the slope (m) using the formula:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1} \\\\m = \frac{0 - 1 }{4 - 0} \\\\m = -\frac{1 }{4 }[/tex]
Next, plug the slope m = -1/4 and one point (0,1) into the point-slope form and simplify:
( y - y₁ ) = m( x - x₁ )
[tex]y - 1 = -\frac{1}{4}( x - 0 ) \\\\y - 1 = -\frac{1}{4}x\\\\y = -\frac{1}{4}x + 1[/tex]
Therefore, the equation of the line is [tex]y = -\frac{1}{4}x + 1[/tex].
