Distance Conversions The United States, Liberia, and Myanmar are the only three countries that have not adopted the metric system as its primary system of measurement. There have been reports and legislation calling for a conversion to the metric system since the 1960s. The U.S. Department of Commerce's National Institute of Standards and Technology wrote that "industrial and commercial productivity, mathematics and science education, and the competitiveness of American products and services in world markets, will be enhanced by completing the change to the metric system of units" (1997, 2). From a student's perspective, it would be better if the U.S. converted to the metric system. Because scientists globally use the metric system, most of U.S. scientists do, as well. Until the U.S. "metrifies", students in the United States will need to continue to use and understand both measurement systems. 6. Refer to Appendix 2.1.

If 1600 square centimeters of material is available to make a box with a square base and an open top, find the largest possible volume of the box.
Answers
The largest possible volume of the box is 6158.394 cm^3.
Define the dimensions of the box to be L, W, and H.
Square base, L = W
Area: A = L^2 * H
Surface Area (Base + Area of 4 sides):
1600 = L^2 + 4 (L*H) ⇒ H = (1600 - L^2) / (4L)
Area: A = 400L - (1/4)L^3
Maximum (Derivative) A' = 400 - (3/4)L^2
Solving for 0
0 = 400 - (3/4)L^2
L^2 ⇒ (40 * SQRT(3)) / 3 = 23.094 (Maximum)
Solving for dimensions, known L=23.094
L = 23.094 cm
W = 23.094 cm
H ⇒ (1600 - L^2) / (4L) = (20 * SQRT(3) / 3) = 11.547 cm
Volume ⇒ L*W*H = 6158.394 cm^3
To locate the most viable extent, add the greatest viable mistakes to every dimension, then multiply. To find the minimum viable volume, subtract the greatest feasible mistakes from each measurement, then multiply.

(the order of the $5$ players in the lineup does not matter; that is, two lineups are the same if they consist of the same $5$ players.)
Answers
The total number of starting lineups (of 5 players) can coach yells lot make, if the starting lineup can't contain both bob and yogi is 672.
What is starting lineups?An official list of the players who will take part in the event when the game starts is known as a starting lineup in sports. The players who are in the starting lineup are frequently referred to as starters, while the rest are known as bench players or replacements.
Case 1: Bob starts (and Yogi doesn't). In this case, the coach must choose 4 more players from the 10 remaining players (remember that Yogi won't play, so there are only 10 players left to select from). Thus there are 10C4 lineups that the coach can choose.
⇒ ¹⁰C₄ = 10!/4!(10-4)! = 10!/4!6!
⇒ ¹⁰C₄ = (10*8*9*7)/(4*3*2*1)
⇒ ¹⁰C₄ = 210
Case 2: Yogi starts (and Bob doesn't). As in Case 1, the coach must choose 4 more players from the 10 remaining players. So there are 10C4 lineups in this case.
⇒ ¹⁰C₄ = 210
Case 3: Neither Bob nor Yogi starts. In this case, the coach must choose all 5 players in the lineup from the 10 remaining players. Hence there are 10C5 lineups in this case.
⇒ ¹⁰C₅ = 10!/5!(10-5)! = 10!/5!5!
⇒ ¹⁰C₅ = (10*8*9*7*6)/(5*4*3*2*1)
⇒ ¹⁰C₅ = 252
To get the total number of starting lineups, we add the number of lineups in each of the cases:
Case 1 + Case 2 + Case 3
= 210 + 210 + 252 = 672

Answers
Answer:
How does computer make you work easier
To calculate the height of the pole, we can use the tangent of the angle between the ground and the pole.The tangent of the angle of 45° is the opposite side (the height of the pole) divided by the adjacent side (the distance from the pole to the observer).The tangent of the angle of 60° is the opposite side (the height of the pole) divided by the adjacent side (the distance from the pole to the observer plus 10m).We can use these two equations to set up a system of equations and solve for the height of the pole:tan(45°) = h / xtan(60°) = h / (x + 10)Where h is the height of the pole and x is the distance from the pole to the observer.By solving this system of equations, we get: h = (x * tan(60°)) + (10 * tan(45°))Since we know that x = 10m, we can substitute that value into the equation and get:h = (10 * tan(60°)) + (10 * tan(45°))h = 14.14213562373095The height of the pole is approximately 14.14 meters.

Part B
He buys a second property that has 0.62 times as many acres as the first property. How many acres of land does the second property have?
Answers
For the park: 6.125 acres * 0.25 = 1.53125 acres
For the second property: 6.125 acres * 0.62 = 3.7975 acres
The builder plans to use 0.25 of the 6.125-acre land for a park. To determine how many acres will be used for the park, we need to multiply the total land area (6.125 acres) by the fraction allocated for the park (0.25). The calculation is as follows: 6.125 acres * 0.25 = 1.53125 acres. Therefore, the builder will use 1.53125 acres of land for the park.
For Part B, the builder buys a second property with 0.62 times as many acres as the first property. To find out how many acres the second property has, we need to multiply the first property's total acres (6.125 acres) by 0.62. The calculation is as follows: 6.125 acres * 0.62 = 3.7975 acres.

If you are dealing with a data set that consists of sales with a consistent percentage increase, what type of method would be best? Random walk additive regression model Multiplicative regression model Simple moving average
Answers
If you are dealing with a data set that consists of sales with a consistent percentage increase, a multiplicative regression model would be the best method to use.
What is multiplicative model?Multiplicative models are useful when the relationship between variables is not linear, but rather exponential or logarithmic. In the case of sales with a consistent percentage increase, the relationship between sales and time would be multiplicative, because each successive time period's sales would be a multiple of the previous period's sales. Multiplicative models are also useful for dealing with trends that increase or decrease at an accelerating rate, rather than at a consistent rate. In contrast, a simple moving average or a random walk additive regression model would not be appropriate for a data set with a consistent percentage increase, as they assume linear relationships between variables and would not account for the exponential or logarithmic relationship between sales and time.

Two chemical plants, one in Macon and one in Jonesboro, produce three types of fertilizer: LP, MP, and HP. The Macon plant produces 1 ton of LP, 2 tons of MP, and 3 tons of HP per hour. The Jonesboro plant produces 1 ton of LP, 5 tons of MP, and 1 ton of HP. On any given day, the company needs to produce atleast 100 tons of LP, 260 tons of MP, and 180 tons of HP. If it costs $600 per hour to run the Macon plant, and $1000 an hour to run the Jonesboro plant, how many hours should each plant be run in order to minimize cost?-I'm not sure what the correct variables are and how to make the right equations I need to graph. I need to solve this problem by creating equations like 6x+7y>100. Then once I have them I need to graph all of then and shade the line based on the inequality sign. If someone could help that would be great!
Answers
We have a linear optimization problem.
We have two plants with different capacity for each type of fertilizer. Each hour, the plant can produce a mix of the products.
Each plant has an associated cost per hour of operation.
Let:
J: the number of operation hours of the Jonesboro plant
M: the number of operation hours of the Macon plant
We can write the total production for the LP fertilizer as:
\(\begin{gathered} 1\cdot J+1\cdot M\ge100 \\ J+M\ge100 \end{gathered}\)Each plant produces one ton per hour, and the total production of both plants togheter has to be 100 tons or more.
For the MP fertilizer, we can similarly write:
\(5J+2M\ge260\)For the HP fertilizer, we can write:
\(J+3M\ge180\)We have the equations of the restrictions:
\(\begin{gathered} J+M\ge100 \\ 5J+2M\ge260 \\ J+3M\ge180 \end{gathered}\)The objective function is the cost function, that have to be minimized:
\(1000J+600M\)We can graph the restrictions as:
(J is written as x and M as y)
Now we can graph the objective function, and minimize satisfying all the restrictions:
We can see that the minimization happens when the MP and HP restrictions meet (both restrictions are "saturated").
Then, we can write:
\(\begin{gathered} 5J+2M=260 \\ J+3M=180\longrightarrow J=180-3M \\ \\ 5(180-3M)+2M=260 \\ 900-15M+2M=260 \\ 900-13M=260 \\ 13M=900-260 \\ 13M=640 \\ M=\frac{640}{13}\approx49.231 \\ \\ J=180-3M=180-3(49.231)=180-147.693=32.307 \end{gathered}\)The cost is:
\(1000J+600M=1000\cdot32.307+600\cdot49.231=32,307+29,538.60=61,845.60\)The combination that minimize the cost is:
Hours of Jonesboro plant: 32.307 hours
Hours of Macon plant: 49.231 hours.

the weights of certain machine components are normally distributed with a mean of 5.12 ounces and a standard deviation of 0.07 ounces. find the two weights that separate the top 5% and the bottom 5% . these weights could serve as limits used to identify which components should be rejected. round your answer to the nearest hundredth, if necessary.
Answers
The weight that separates the bottom 5% is approximately 5.02 ounces.
To find the weights that separate the top 5% and the bottom 5%, we need to use the z-score formula and the standard normal distribution table.
First, let's find the z-score for the top 5%. Using the standard normal distribution table, we find that the z-score for the top 5% is approximately 1.645.
Next, we can use the formula z = (x - μ) / σ, where z is the z-score, x is the weight we're trying to find, μ is the mean, and σ is the standard deviation.
For the top 5%, we have:
1.645 = (x - 5.12) / 0.07
Solving for x, we get:
x = 5.12 + 1.645 * 0.07
x ≈ 5.22 ounces
Therefore, the weight that separates the top 5% is approximately 5.22 ounces.
To find the weight that separates the bottom 5%, we use the same process but with a negative z-score. The z-score for the bottom 5% is approximately -1.645.
-1.645 = (x - 5.12) / 0.07
Solving for x, we get:
x = 5.12 - 1.645 * 0.07
x ≈ 5.02 ounces
Therefore, the weight that separates the bottom 5% is approximately 5.02 ounces.
These weights could serve as limits used to identify which components should be rejected. Any component with a weight less than 5.02 ounces or greater than 5.22 ounces should be rejected.

Answer:
C ≈ 26.7
Step-by-step explanation:
The given equation to solve is F = \(\frac{9}{5}\)C + 32.
F is given the value of 80.
So, the equation to solve is 80 = \(\frac{9}{5}\\\)C + 32.
\(\frac{9}{5}\)C + 32 = 80 First, isolate the variable C by subtracting 32 from both sides.
\(\frac{9}{5}\)C = 48 Next, show C in its true form by multiplying both sides by the reciprocal of \(\frac{9}{5}\).
\(\frac{5}{9}\)(\(\frac{9}{5}\)C) = \(\frac{5}{9}\)(48)
C = 26.666→∞
Rounding to the nearest tenth, the value of C is 26.7 °C.
The answer you are looking for is
Solution/Explanation:
Writing out the formula for converting Fahrenheit and Celsius first
F=9/5C+32
Substituting the given value of the "F" or "Fahrenheit" variable, 80,
80=9/5C+32
Subtracting 32 from both sides
80-32=9/5C+32-32
Since 32-32=0, this cancels out.
80-32=9/5C+0
80-32=9/5C
Simplifying 80-32, which is 48
48=9/5C
Multiplying both sides by 5
(48)(5)=(9/5C)(5)
Simplifying both sides of the equation
240=9C
Finally, dividing both sides of the equation by 9
240/9=9C/9
240/9=26.6667
9C/9=C
You will get 26.6667=C, or C=26.6667.
You can round 26.6667 to the nearest tenth as approximately 26.7.
So, therefore, the final answer to this problem is C≈26.7°C.
