a trapezoid is shown with bases AD and BC. if slopCe of AD is 1/2, what is the slope of BC
Answers
The slope of BC is 1/2, since the slope of AD is 1/2. This is because the rise and run of the two bases are the same.
What is slope?The slope of a line is defined as the ratio of the vertical change (the rise) to the horizontal change (the run).
In the case of an isosceles trapezoid, the two bases (AD and BC) are parallel and of equal length. Therefore, the slope of the two bases is the same.
Given that the slope of AD is 1/2, the slope of BC is also 1/2.
This is because the rise and run of the two bases are the same. Therefore, the ratio of rise to run is the same and the slope of both bases is 1/2.
To understand this better, let us consider the rise and run of the two bases:
AD: Rise = y² − y1, Run = x² − x1
BC: Rise = y² − y1, Run = x² − x1
Therefore,
Slope of AD = (y² − y1)/(x² − x1)
Slope of BC = (y² − y1)/(x² − x1)
Since the rise and run of the two bases are the same, the slope of the two bases is also the same.
Therefore, the slope of BC is 1/2, since the slope of AD is 1/2.

How to find?
The composition r x-axis ° T(7,5) first reflects the quadrilateral MATH about the x-axis and then translates it 7 units to the right and 5 units up.
To find the image of M(-6,-3) after reflection about the x-axis, we flip the sign of the y-coordinate to get M'(-6,3). Then, we translate M' 7 units to the right and 5 units up to get the coordinates of M":
M" = T(7,5) ∘ M' = (7 + (-6), 5 + 3) = (1, 8)
Similarly, we can find the coordinates of A", T", and H":
A' = (-1, 3) → A" = T(7,5) ∘ R(x-axis) ∘ A' = (7 + (-1), 5 - 3) = (6, 2)
T' = (-2, 1) → T" = T(7,5) ∘ R(x-axis) ∘ T' = (7 + (-2), 5 - 1) = (5, 4)
H' = (-4, 1) → H" = T(7,5) ∘ R(x-axis) ∘ H' = (7 + (-4), 5 - 1) = (3, 4)
Therefore, the coordinates of M"A"T"H" are M"(1,8), A"(6,2), T"(5,4), and H"(3,4).

Mr Lim, Mr Bell and Mrs Walker paid for a meal. Mr Lim paid 1/5 of the amount Mr Bell and Mrs Walker paid together. Mr Bell paid 1/4 of the amount Mr Lim and Mrs Walker paid. A) What fraction of the total cost of the meal did Mrs Walker pay?
Answers
As a result, Mrs. Walker contributed a portion of the overall cost of the supper, which is: 400/61 - (16B + 25L) / (61C) (61C)
what is fraction ?A fraction is a number that in mathematics represents a portion of a whole. It consists of a horizontal line between the numerator and denominator of two numbers. The denominator is the total number of equally sized components that make up the whole, whereas the numerator is the number of parts that are being taken into account. As an illustration, the fraction 3/4 denotes three of the four equal pieces. The denominator, 4, indicates that the entire is divided into four equal parts, while the numerator, 3, indicates that three parts are being taken into consideration.
given
Payment to Mr. Lim:
1/5(B + W) = (B + W)/5
Payment to Mr. Bell:
1/4(L + W) = (L + W)/4
These equations can be combined to find the value of W, or the amount Mrs. Walker paid:
(L + W)/4 + W + (B + W)/5 = C
To get rid of the fractions, multiply both sides by 20, which is the least common multiple of 5 and 4. This gives us:
20W + 4(B + W) + 5(L + W) = 20C
By enlarging and condensing, we obtain:
20C = 4B + 4W + 5L + 5W + 20W
9W + 4B + 5L = 20C
Now, we may change the expressions for the payments made to Mr. Lim and Mr. Bell to:
9W plus 4 (1/5 B + W) plus 5 (1/4 L + W) equals 20C.
If we simplify, we get:
9W + 4B + 4W + 4W + 4W + 5L + 5W = 20C.
When we multiply both sides by 20 to once more get rid of the fractions, we get:
400C = 180W + 16B + 16W + 25L + 25W
20C = 4B + 4W + 5L + 5W + 20W
9W + 4B + 5L = 20C
Now, we may change the expressions for the payments made to Mr. Lim
If we simplify, we get:
61W + 16B + 25L = 400C
We may now determine W:
W = (400C - 16B - 25L) / 61
We can divide W by the overall cost C to determine the portion of the cost of the lunch that Mrs. Walker covered:
W/C = (400C - 16B - 25L) / (61C)
W/C = 400/61 - (16B + 25L) / (simplified) (61C)
As a result, Mrs. Walker contributed a portion of the overall cost of the supper, which is: 400/61 - (16B + 25L) / (61C) (61C) .

Answers
Sue needs to sell 16 rings to make her revenue equal to her expenses
What is revenue?Revenue is the total income generated by a company or organization from its sales or operations. It is the amount of money that a business earns from selling its products or services, or from other sources such as investments or interest on deposits.
According to question:Let's assume that Sue sells x rings.
The revenue generated by selling x rings = $6x
The total expenses for selling x rings = $2.50x + $56
To find the number of rings that Sue needs to sell for her revenue to equal her expenses, we need to set the revenue equal to the expenses and solve for x.
6x = 2.5x + 56
Subtracting 2.5x from both sides, we get:
6x - 2.5x = 56
Simplifying the left side, we get:
3.5x = 56
Dividing both sides by 3.5, we get:
x = 16
Therefore, Sue needs to sell 16 rings to make her revenue equal to her expenses.

Correct ___17.65___ bacteria
Find the doubling period.
____?_____ minutes

____?_____ bacteria
When will the population reach 12000.
___?____ minutes
Answers
The population will reach 12000 bacteria after 56.4 minutes and other solutions are listed below
What was the initial size of the culture?We can use the formula for exponential growth, which is given by:
N = N0 * e^(kt)
where N is the final population, N0 is the initial population, k is the growth rate constant, and t is time.
To find the initial size of the culture, we can use the values given at 15 minutes and 40 minutes:
100 = N0 * e^(15k)
1800 = N0 * e^(40k)
Dividing the second equation by the first, we get:
18 = e^(25k)
Taking the natural logarithm of both sides, we get:
k = ln(18)/25
Solving for k, we get:
k = 0.1156
Substituting this value of k into the first equation, we can solve for N0:
100 = N0 * e^(15 * 0.1156)
N0 = 17.65
Therefore, the initial size of the culture was 17.65 bacteria.
The doubling periodTo find the doubling period, we use the fact that the population doubles when t increases by a certain amount, which we'll call T. That is:
N0 * e^(kT) = 2N0
Dividing by N0 and taking the natural logarithm of both sides, we get:
T = ln(2)/k
Solving for T, we get:
T = ln(2)/k ≈ 6.00 minutes
Therefore, the doubling period is approximately 6 minutes.
The population after 115 minutesTo find the population after 115 minutes, we can use the formula with the values of N0, k, and t:
N = N0 * e^(kt) = 17.65 * e^(0.1156 * 115) ≈ 10477448.92
Therefore, the population after 115 minutes is approximately 10477448.92 bacteria.
When the population reaches 12000To find when the population reaches 12000, we set N equal to 12000 and solve for t:
12000 = 17.65 * e^(0.1156t)
Dividing by 17.65 and taking the natural logarithm of both sides, we get:
ln(12000/17.65 ) = 0.1156t
Solving for t, we get:
t ≈ 56.42 minutes
Therefore, the population will reach 12000 bacteria after approximately 56.4 minutes.

Find the average rate of change of f(x) = x² - 4x + 1 from x=3 to x = 5.
Simplify your answer as much as possible.
Answers
To find the average rate of change of the function f(x) = x² - 4x + 1 from x=3 to x = 5, we need to find the difference in f(x) between these two values and divide by the difference in x:
f(5) - f(3) / (5 - 3)
= (5² - 4(5) + 1) - (3² - 4(3) + 1) / 2
= (25 - 20 + 1) - (9 - 12 + 1) / 2
= (6) / 2
= 3
Therefore, the average rate of change of f(x) from x=3 to x=5 is 3.
Step-by-step explanation:
Given a interval x=a to x=b, the average rate of change is equal to
[tex] \frac{f(b) - f(a)}{b - a} [/tex]
where [a,b] is the interval.
Here
a is 3
b is 5 so
[tex] \frac{f(5) - f(3)}{5 - 3} [/tex]
Using the function
[tex]f(5) = 25 - 20 + 1 = 6[/tex]
[tex]f(3) = 9 - 12 + 1 = - 2[/tex]
So
[tex] \frac{6 - ( - 2)}{5 - 3} = 4[/tex]
The average rate of change of f from x=3 to x=5 is 4

Answers
Answer:
Step-by-step explanation:
To find x + 1/x, we need to first find the value of x.
Given, x = 2-√3
To simplify x + 1/x, we need to find the value of 1/x.
1/x = 1/(2-√3)
Multiplying the numerator and denominator by the conjugate of the denominator, we get:
1/x = (2+√3)/(2-√3)(2+√3)
1/x = (2+√3)/(4-3)
1/x = 2+√3
Now, substituting the values of x and 1/x, we get:
x + 1/x = (2-√3) + (2+√3)
x + 1/x = 4
Therefore, the answer is option a) 4.

Answers
Answer: f(x) is -74(x+1/7)^(-1/2)
Step-by-step explanation:
To find the derivative of f(x), we can use the power rule and the chain rule.
First, let's rewrite f(x) as:
f(x) = -148(x+1/7)^(1/2)
Now, we can apply the power rule:
f'(x) = -148 * (1/2) * (x+1/7)^(-1/2)
Finally, we can use the chain rule:
f'(x) = -148 * (1/2) * (x+1/7)^(-1/2) * 1
f'(x) = -74(x+1/7)^(-1/2)
Therefore, the derivative of f(x) is -74(x+1/7)^(-1/2).

Answers
The expected number of students who classify the crown shapes as medium is approximately 38.3.
What is statistics?
Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of numerical data.
To find the expected number of students who classify the crown shapes as medium, we need to use the assumption that the distributions of responses from the professionals and the students are the same. We can use the row and column totals to calculate the expected counts.
First, let's calculate the marginal totals for the students:
The total number of students is 91.
The total number of students who classified the crown shapes as low is 43.
The total number of students who classified the crown shapes as medium is 39.
The total number of students who classified the crown shapes as high is 9.
Now let's calculate the expected counts for the students who classified the crown shapes as medium:
The total number of classifications for the medium category is 87 (from the table).
The proportion of classifications in the medium category made by the professionals is 48/109.
The expected number of classifications in the medium category made by the students can be calculated as (proportion from professionals) x (total number of student classifications) = (48/109) x 87 = 38.3 (rounded to one decimal place).
Therefore, the expected number of students who classify the crown shapes as medium is approximately 38.3.

Answers
Answer:
-6x + 6y = 6 (Equation 1)
-6x + 3y = -12 (Equation 2)
We can use the method of elimination, which involves adding or subtracting the equations to eliminate one of the variables.
In this case, we can start by multiplying Equation 2 by 2 to eliminate the x variable:
-6x + 6y = 6 (Equation 1)
-12x + 6y = -24 (Equation 2 multiplied by 2)
Now we can subtract Equation 1 from Equation 2:
-12x + 6y = -24 (Equation 2 multiplied by 2)
-(-6x + 6y = 6) (Equation 1, with the opposite sign)
-6x = -30
Simplifying this expression, we get:
x = 5
Now we can substitute this value of x into either Equation 1 or Equation 2 to solve for y. Let's use Equation 1:
-6x + 6y = 6
-6(5) + 6y = 6
-30 + 6y = 6
6y = 36
y = 6
Therefore, the solution to the system of equations is x = 5 and y = 6, or (5, 6) in coordinate form.

1. Nathaniel hikes 15 4/5 kilometres on a
three-day hiking trip.He hikes 3 kilometre
on the first day.Then
Nathaniel hikes the same distance on
the second and third days of his trip.
Determine the distance Nathaniel hikes
on the second and third days.
Answers
Nathaniel hikes 6 2/5 kilometers on each of the second and third days of his hiking trip.
Calculating the distance hiked on the second and third daysIf Nathaniel hikes a total of 15 4/5 kilometers on a three-day hiking trip and he hikes 3 kilometers on the first day, then he must hike the remaining distance on the second and third days.
To find out how much Nathaniel hikes on the second and third days, we can start by subtracting the distance he hikes on the first day from the total distance he hikes:
15 4/5 - 3 = 12 4/5 kilometers
Since Nathaniel hikes the same distance on the second and third days, we can divide the remaining distance by 2 to find out how much he hikes on each of those days:
12 4/5 ÷ 2 = 6 2/5 kilometers
Therefore, Nathaniel hikes 6 2/5 kilometers on each of the second and third days of his hiking trip.

x = -2
2(-2) + 5y = 6
5y - 4 = 6
5y = 10
10/5=2
y = 2
- So x = -2, because you divided both sides by 4
2x + 5y = 6
You input your solution of x into the variable
-So it would be 2(-2) + 5y = 6
- so y = 2
Solution: X= -2 Y= 2 (-2,2)

What is
A
Astart color #9e034e, start text, A, end text, end color #9e034e rounded to the nearest tenth?
Answers
the rounded color remains the original colour:: 9e034e
The color code #9e034e represents a shade of deep pink or magenta. To round this color to the nearest tenth, we need to convert the hexadecimal code to its corresponding RGB values and then round those values.
Converting #9e034e to RGB gives us (158, 3, 78).
Rounding each of these values to the nearest tenth gives us (158, 3, 78), which is the same as the original color. Therefore, the rounded color is still #9e034e.
As for the mention of "A" in the question, it's unclear what context it refers to. If it's related to the color, it might mean that the color is used to represent the letter "A" in a certain context. However,
The question doesn't provide enough information to determine the exact meaning of "A."n summary, the rounded color #9e034e remains the same as the original color, and the mention of "A" in the question is unclear.

Solve the system.
x + y = 2
x – y = 0
Answers
Both equations are true when x = 1 and y = 1, so the solution is correct.
What are system of equations ?
A system of equations is a set of two or more equations that are to be solved simultaneously. The equations in the system share common variables, and the solution to the system is a set of values for those variables that satisfy all of the equations in the system.
To solve this system, we need to find the values of x and y that satisfy both equations at the same time. This means that any solution we find must work in both equations simultaneously.
According to the question:
To solve the system:
x + y = 2 ...(1)
x - y = 0 ...(2)
We can add equations (1) and (2) to eliminate y:
(x + y) + (x - y) = 2 + 0
2x = 2
x = 1
Substituting x = 1 into equation (1):
1 + y = 2
y = 1
Therefore, the solution to the system is x = 1 and y = 1. We can check the solution by substituting the values into both equations
x + y = 2
1 + 1 = 2 (true)
x - y = 0
1 - 1 = 0 (true)
Both equations are true when x = 1 and y = 1, so the solution is correct.

A triangular prism has a volume of 1950 cm?. The height of the triangle is 13 cm, and the height of the prism is 20 cm. What is the perimeter of the triangle (assuming all the sides are equal)?
Answers
The perimeter of the triangle is therefore P= 45 cm.
What is a triangular prism?A triangular prism is a prism composed of two triangular bases and three rectangular sides. It is a pentahedron.
What is perimeter?The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape.
We know that the volume of a prism is given by
V = Bh, where B is the area of the base and h is the height of the prism. In this case, we have V = 1950 cm³ and h = 20 cm.
So, we can solve for B:
B = V/h = 1950/20 = 97.5 cm².
The base of the triangular prism is a triangle with height 13 cm, so we have
B = 1/2bh = 1/2(13)(b) = 97.5.
Solving for b, we get b = 2B/h = 2(97.5)/13 = 15 cm.
Since all sides of the triangle are equal, we have b = c = 15 cm.
The perimeter of the triangle is therefore P = 3b = 3c = 3(15) = 45 cm.
