Problem 2: Given are a segment AB and a ray CD. Use compass, straightedge, and pencil,
to construct a point X on CD such that
CX = 2 1/2 AB
Answers
m is parallel to AB, and passing through points C.
Therefore, m II AB.
In geometry, a line segment is a part of a line bounded by two distinct endpoints and contains every point of the line between its endpoints. The length of a line segment is given by the Euclidean distance between its endpoints. A closed segment includes two endpoints, an open segment does not include both endpoints; a half-open segment has exactly one end. In geometry, a line segment is usually represented using a line above the two end symbols (like AB).
We use the basic rules of construction to draw lines according to the problem.
Draw a straight line AB and take a point C outside of it. Using a ruler and compass to draw the AB line, follow the steps below:
Draw a line AB, and take a point C outside this line. Take any point P on AB.Connect C to P.Take P as the center of the circle, take a suitable radius, draw an arc and cut AB in D, and PC in E.With C as the center and the same radius as in the previous step, draw an arc FG, and PC to H.Adjust the compass to the length of DE. Without changing the compass aperture, draw an arc HG at point I with H as the center.Draw a line l connecting points C and I as shown in the figure.Therefore, the line l is parallel to the line AB.

Answers
Answer:
1.6
Step-by-step explanation:
The stock turnover at retail is a measure of how many times a business sells its average inventory during a period of time. We can calculate the stock turnover by dividing the retail sales by the average inventory.
Stock turnover = Retail Sales / Average Inventory
Given the values :
Average Inventory = $123,456Retail Sales = $196,450Substituting these values
Stock turnover at retail = 196,450 / 123,456 = 1.6 (rounded to the nearest tenth)

Ruben and Estelle just had business cards made. Ruben's printing company charged a one-time setup fee of $8 and then $18 per box of cards. Estelle, meanwhile, ordered hers online. They cost $6 per box. There was no setup fee, but she had to pay $20 to have her order shipped to her house. By coincidence, Ruben and Estelle ended up spending the same amount on their business cards. How much did each spend? How many boxes did each buy?
Answers
Ruben ordered 0 boxes of cards and Estelle ordered 2 boxes of cards. Ruben spent $8 and Estelle spent $20 + $6(2) = $32.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
Let's start by setting up equations for the total cost of Ruben and Estelle's business cards. Let R be the number of boxes of cards Ruben ordered and E be the number of boxes Estelle ordered. Then we have:
Ruben's cost = 8 + 18R
Estelle's cost = 6E + 20
We know that Ruben and Estelle spent the same amount, so we can set their costs equal to each other and solve for R and E:
8 + 18R = 6E + 20
18R - 6E = 12
3R - E = 2
This equation tells us that Ruben ordered two more boxes of cards than Estelle. We can use trial and error to find the values of R and E that satisfy this equation and give us the same cost:
If R = 4 and E = 2, then Ruben's cost = 8 + 18(4) = 80 and Estelle's cost = 6(2) + 20 = 32, which are not equal.
If R = 3 and E = 1, then Ruben's cost = 8 + 18(3) = 62 and Estelle's cost = 6(1) + 20 = 26, which are not equal.
If R = 2 and E = 0, then Ruben's cost = 8 + 18(2) = 44 and Estelle's cost = 6(0) + 20 = 20, which are not equal.
If R = 1 and E = -1, then Ruben's cost = 8 + 18(1) = 26 and Estelle's cost = 6(-1) + 20 = 14, which are not equal.
If R = 0 and E = -2, then Ruben's cost = 8 + 18(0) = 8 and Estelle's cost = 6(-2) + 20 = 8, which are equal.
Therefore, Ruben ordered 0 boxes of cards and Estelle ordered 2 boxes of cards. Ruben spent $8 and Estelle spent $20 + $6(2) = $32.

Answers
The function representing the daily profit based on production of premium coffee is given by ,
T = [tex]\int_{1}^{x}[/tex] [(t² + 1 ) / t² ] dt + (13,500 + (1/x) - x)
Function for daily profit associated with the production of excel so coffee is equal to,
G(x) =[tex]\int_{1}^{x}[/tex] [(t² + 1 ) / t² ] dt
Let's assume that the profit per kilogram of premium coffee is p dollars.
And total production of premium coffee is y kilograms per day.
Total profit from premium coffee is P = p × y
Company produces a total of 4000 kilograms of coffee per day.
⇒ y = 4000 - x
x = production of traditional coffee in kilograms per day.
Total profit for the company is,
T = G(x) + P
Substituting the expressions for P and y,
T = G(x) + p × (4000 - x)
Company's daily profit from producing traditional coffee = $13,500
⇒ 13,500 = G(x) + 4 × x
Substituted the marginal profit of $4 per kilogram for traditional coffee.
Profit per kilogram of premium coffee, p, in terms of x is equal to,
⇒ T = G(x) + p × (4000 - x)
⇒ 13,500 = G(x) + p×(4000 - x)
⇒ 13,500 = [tex]\int_{1}^{x}[/tex][(t² + 1 ) / t² ] dt + p×(4000 - x)
⇒ 13,500 = [x - (1/x)] + p× (4000 - x)
⇒13,500 = x - (1/x) + 4000p - px
⇒ 13,500 = (1-p)x - (1/x) + 4000p
p = (13,500 + (1/x) - x)/(4000 - x)
Function for daily profit associated with the production of premium coffee is,
T = G(x) + (13,500 + (1/x) - x)/(4000 - x) × (4000 - x )
Simplifying we get,
⇒ T = G(x) + (13,500 + (1/x) - x)
Therefore, the function for daily profit associated with the production of premium coffee is equal to
T = [tex]\int_{1}^{x}[/tex] [(t² + 1 ) / t² ] dt + (13,500 + (1/x) - x)

The sides of a triangle are 54, 31, and 69. Use the Pythagorean Theorem to determine if the triangle is right, acute, or obtuse.
Answers
The triangle is acute since a² + b² < c² ( 2916 + 961 < 4761.
Is the triangle is right, acute, or obtuse?To determine whether the triangle is right, acute, or obtuse, we can use the Pythagorean Theorem, which states that in a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.
We can start by finding the longest side of the triangle, which is the hypotenuse.
hypotenuse = 69
Now we can use the Pythagorean Theorem to check whether the triangle is right:
a² + b² = c²
where a and b are the lengths of the other two sides of the triangle.
Plugging in the values we know, we get:
54² + 31² = 69²
Simplifying, we get:
2916 + 961 = 4761
3877 = 4761
Since this equation is not true, we know that the triangle is not a right triangle.
To determine whether the triangle is acute or obtuse, we need to compare the sum of the squares of the lengths of the shorter sides to the square of the length of the longest side:
a² + b² < c² => the triangle is acute
a² + b² > c² => the triangle is obtuse
c² = 69² = 4761
Plugging in the values we know, we get:
54² + 31² = 2916 + 961 = 3877
Since 3877 < 4761, we can conclude that the triangle is acute.

A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 100 nails and each large box has 450 nails. The contractor bought 3 more small boxes than large boxes, which all together had 2500 nails. Determine the number of small boxes purchased and the number of large boxes purchased. PLEASE HELP!!
Answers
Answer: Let's call the number of large boxes purchased "L" and the number of small boxes purchased "S".
From the problem, we know that:
Each small box has 100 nails, so the total number of nails from the small boxes is 100S.
Each large box has 450 nails, so the total number of nails from the large boxes is 450L.
The contractor bought 3 more small boxes than large boxes, so S = L + 3.
The total number of nails purchased is 2500, so 100S + 450L = 2500.
We can use the second equation to solve for one of the variables in terms of the other. For example, we can solve for L:
100S + 450L = 2500
Substituting S = L + 3:
100(L + 3) + 450L = 2500
Expanding the parentheses:
100L + 300 + 450L = 2500
Combining like terms:
550L + 300 = 2500
Subtracting 300 from both sides:
550L = 2200
Dividing both sides by 550:
L = 4
So the contractor purchased 4 large boxes of nails.
We can use the equation S = L + 3 to find the number of small boxes purchased:
S = L + 3 = 4 + 3 = 7
So the contractor purchased 7 small boxes of nails.
Therefore, the contractor purchased 4 large boxes and 7 small boxes of nails.

The surface area of this rectangular prism is 94 square feet. What is the volume
Answers
The volume of the rectangular prism is 60 cubic feet.
What is a rectangular prism?
A rectangular prism is a three-dimensional geometric shape with six faces, where each face is a rectangle. It is also known as a rectangular cuboid. A rectangular prism has 8 vertices, 12 edges, and 6 rectangular faces. The opposite faces of a rectangular prism are congruent and parallel to each other. The length (l), width (w), and height (h) of a rectangular prism are the three dimensions that determine its size and shape.
The formula for the surface area of a rectangular prism is:
SA = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the prism, respectively.
In this case, we have l = r, b = 5ft, h = 3ft, and SA = 94 sq ft. Substituting these values into the formula, we get:
94 = 2(r)(5) + 2(r)(3) + 2(5)(3)
94 = 10r + 6r + 30
94 = 16r + 30
64 = 16r
r = 4
So, the length of the rectangular prism is 4 feet.
Now, we can use the formula for the volume of a rectangular prism:
V = lwh
Substituting the values for l, w, and h, we get:
V = (4)(5)(3) = 60 cubic feet
Therefore, the volume of the rectangular prism is 60 cubic feet.

Emmy watson is buying a new oven for 915. 0. She made a down payment of 20% and financed the remainder. How much did she finance
Answers
Answer: Emmy Watson made a down payment of 20%, which means she paid 20% of the total cost of the oven upfront.
20% of 915.0 = 0.20 x 915.0 = 183.0
So, Emmy Watson paid $183.0 as a down payment.
To find out how much she financed, we need to subtract the down payment from the total cost of the oven:
Financed amount = Total cost - Down payment
Financed amount = $915.0 - $183.0
Financed amount = $732.0
Therefore, Emmy Watson financed $732.0.

We can say that after answering the offered question The ladder is Pythagorean theorem therefore 15 feet long, rounded up to the next foot. Thus, 15 feet is the solution.
what is Pythagorean theorem?The Pythagorean Theorem is the foundational Euclidean geometry connection that exists between the three sides of the right triangle. According to this rule, the area of either a cube with the length x side is equal to the total of the regions of triangles shared by its other two sides. According to the Pythagorean Theorem, the square that spans the hypotenuse of a right triangle opposite the perfect angle is the combined squares that spanned its sides. It is sometimes expressed as a2 + b2 = c2 in general algebraic notation.
The ladder serves as the hypotenuse in this basic example of a right triangle, which also includes the distance from the house as one of its legs and the ladder's height as its second leg. The Pythagorean theorem can be used to find the ladder's length.
[tex]c^2 = a^2 + b^2[/tex]
In this instance, we know that the distance from the house (a) is 9 feet, and the height of the ladder (b) is 12 feet. Hence, we can enter these values into the formula as follows:
[tex]c^2 = 9^2 + 12^2 c^2 = 81 + 144\sc^2 = 225\sc = √225\sc = 15[/tex]
The ladder is therefore 15 feet long, rounded up to the next foot. Thus, 15 feet is the solution.

In hypothesis testing, a null hypothesis is a statement or assumption about a population parameter that we want to test using sample data. The p-value is the probability of obtaining a test statistic as extreme as, or more extreme than, the observed test statistic, assuming the null hypothesis is true.
Now,
To test the hypothesis,
we need to perform a hypothesis test using a significance level (α) to determine whether the sample proportion of satisfied customers is significantly different from 0.9.
The null hypothesis (H0) is that the true proportion of satisfied customers is equal to 0.9. The alternative hypothesis (H1) is that the true proportion is not equal to 0.9.
We can use the normal approximation to the binomial distribution to test this hypothesis, since the sample size is large (n = 1000) and both np and n(1-p) are greater than or equal to 10, where p is the true proportion of satisfied customers.
The test statistic is given by:
z = (P - p0) / √(p0(1 - p0) / n)
where p0 is the proportion (0.9), P is the sample proportion (850/1000 = 0.85), and n is the sample size.
Plugging in the values, we get:
z = (0.85 - 0.9) / √(0.9 * 0.1 / 1000) = -1.5811
The P-value is the probability of getting a test statistic as extreme as -1.5811 or more extreme, assuming the null hypothesis is true. Since this is a two-tailed test (H1: p ≠ 0.9), we need to find the area in both tails of the standard normal distribution.
Using a standard normal distribution table, we find that the area to the left of -1.5811 is 0.0569, and the area to the right of 1.5811 is also 0.0569. Therefore, the total area in both tails is:
p-value = 0.0569 + 0.0569 = 0.1138
So,
the p-value is 0.1138.

A scatter plot of the data is shown below.
An equation of a reasonable trend line is y = x - 0.1.
The arm span of someone who is 1.6 m tall is 1.5 meter.
The arm span of someone who is 2.2 m tall is 2.1 meters.
How to write an equation of the line of best fit for the data?In order to write a linear equation for the line of best fit (trend line) that models the data points contained in the table, we would have to use a graphing calculator (scatter plot).
In this scenario, the heights would be plotted on the x-axis of the scatter plot while the arm span would be plotted on the y-axis of the scatter plot.
At point (2.0, 1.9), an equation of this line can be calculated by using the point-slope form:
y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
y - 1.9 = (2.0 - 1.9)/(2.1 - 2.0)(x - 2.0)
y - 1.9 = (x - 2.0)
y = x - 0.1.
For someone who is 1.6 m tall, their arm span is given by;
y = x - 0.1
y = 1.6 - 0.1.
x = 1.5 meter.
For someone who is 2.2 m tall, their arm span is given by;
y = x - 0.1
y = 2.2 - 0.1.
x = 2.1 meters.

a bowl of fruit is on the kitchen table it contains 5 apples 2 oranges and 2 bananas christian and Aaron come home from school and randomly grab one fruit each what is the probability that both grab oranges
Answers
Answer:
The probability that both grab oranges would be = 1/30
Step-by-step explanation:
bc 1/8 * 2/9 = 1/30
hope this helps
Answer: The probability that both grab oranges would be =1/36
Step-by-step explanation:
Given,
A bowl contains,
Apples = a = 5
Oranges = o = 2
bananas = b = 2
Total fruits in bowl = x = a + o + b = 5 + 2 + 2 = 9
Now, Christian and Aaron come home from school and randomly grab one fruit each.
The probability of first selecting orange would be = o/b =2/9
Now, the oranges left would be 2 - 1 = 1
and total fruits would be = 9 - 1 = 8
Hence, the probability of selecting second orange would be = 1/8
Therefore, the probability that both grab oranges would be = 1/8 2/9 =1/36
