Answer: BD = 60.34
Step-by-step explanation:
8x -33 = 2x+37
Take away 2x from both sides ( the 2x will cancel out)
= 6x - 33= 37
Add the 33 to both sides. (The -33 will cancel out)
Now you are left with 6x = 70
Divide both sides by 6.
x = 11.67 (rounded by the hundredth) (11.66666...)
Now to figure out BD your new equation is 2(11.67) + 37
After multiplying you get 23.34 + 37.
BD = 60.34

The monthly fee is [tex]\boxed{\$\;3.00}[/tex] and the yearly fee is [tex]\boxed{\$\;12.00}[/tex]
Step-by-step explanation:
The graph is a straight line whose equation can be represented in general terms as
y = mx + b
m = slope which is the rate of change of y with respect to x
b = y-intercept which is the value of y when x = 0; also the y-value where the line crosses the y-axis
To find m:
Take any two points on the lineLet's choose (1, 15) and 6, 30) Find the difference in y values. This is called the rise
rise = 30 - 15 = 15Find the corresponding difference in x values. This is called the run
run = 6 - 1 = 5Divide the rise by run to get the slope
Slope m = rise/run = 15/5 = 3So, for starters we can state that
y = 3x + b
To find b:
Let's take point(2, 18)Substitute y and x values in y = 3x + b
18 = 3 x 2 + b
18 = 6 + b
6 + b = 18 (switching sides)
b = 18-6 (subtract 6 both sides)
b = 12
So the equation of the line is
y = 3x + 12

A map of a highway has a scale of 2 inches = 33 miles. The length of the highway on the map is 6 inches. There are 11 rest stops equally spaced on the highway, including one at each end. You are making a new map with a scale of 1 inch = 30 miles. How far apart are the rest stops on the new map?
Answers
Thus, the required rest stops are approximately 4.09 miles apart on the new map.
What is the scale factor?The scale factor is defined as the ratio of the modified change in length to the original length.
Here,
The total length of the highway in miles can be found by using the scale of the original map. Since 2 inches on the map represent 33 miles in reality, 6 inches on the map represent:
= 6 inches × (33 miles/2 inches) = 99 miles
Since there are 11 equally spaced rest stops along the highway,
= (99 miles)/(11 intervals) = 9 miles per interval
To create the new map with a scale of 1 inch = 30 miles, we need to use a scale factor of (1/2) × (30/33) = 15/33.
Therefore, the distance between each rest stop on the new map can be found by multiplying the distance between rest stops on the old map by the scale factor,
= (9 miles per interval) × (15/33) = 4.09 miles per interval
So, the required rest stops are approximately 4.09 miles apart on the new map.

Mckenna spends 7/4 hours mopping the floors and 27/8 hours mowing and weeding the yard how many hours does she needs to spend on her chors
Answers
The total amount of time McKenna spends on her chores is 41/8 hours, or approximately 5.125 hours.
To find the total amount of time McKenna spends on her chores, we need to add up the time she spends mopping the floors and mowing and weeding the yard.
First, let's convert both the time spent mopping the floors and mowing and weeding the yard to a common denominator. The least common multiple of 4 and 8 is 8, so we can convert 7/4 hours to
7/4 * 2/2 = 7/2 hours.
Next, we can add the time spent on each chore:
7/2 hours + 27/8 hours = (14 + 27)/8 hours = 41/8 hours.
So, the total amount of time McKenna spends on her chores is 41/8 hours, or approximately 5.125 hours.
It is important to note that this calculation assumes that the time spent on each chore is a continuous amount of time, rather than broken up into smaller increments throughout the day.

Shape A is reflected in the line with equation x = 2 to give Shape B
Answers
In mathematical terms, each point (x, y) on Shape A is mapped to a point (2 + (2 - x), y) on Shape B as reflected line equation and explained as
When a shape is reflected in a line, it means that each point on the original shape is mapped to a corresponding point on the reflected shape that is symmetrical with respect to the reflecting line.
The line of reflection can be any straight line, and in this case, the line of reflection is given by the equation x = 2. To understand how the reflection works, imagine holding a mirror along the line x = 2 and placing Shape A on the mirror. The reflected shape, Shape B, would be the image that you see in the mirror. In mathematical terms, each point (x, y) on Shape A is mapped to a point (2 + (2 - x), y) on Shape B. This means that for each point on Shape A, we take its x-coordinate, subtract it from 2 to find the distance from the line of reflection, and then add that distance to 2 to find the x-coordinate of the corresponding point on Shape B. The y-coordinate remains the same.
The line of reflection acts as a dividing line between Shape A and Shape B, and the points on Shape B are exactly the same distance from the line of reflection as the points on Shape A, but on the opposite side. This means that Shape B is a perfect mirror image of Shape A, reflected across the line x = 2.
In summary, the reflection of Shape A in the line x = 2 maps each point on Shape A to a corresponding point on Shape B that is symmetrical with respect to the line of reflection. The result is a perfect mirror image of the original shape, reflected across the line.

the mayor of a town believes that above 72% of the residents favor annexation of an adjoining community. is there sufficient evidence at the 0.05 level to support the mayor's claim? state the null and alternative hypotheses for the above scenario.
Answers
Null hypothesis: Proportion of residents favoring annexation <= 72%. Alternative hypothesis: Proportion of residents favoring annexation > 72%
The null hypothesis is that the proportion of residents who favor annexation is equal to or less than 72%. The alternative hypothesis is that the proportion of residents who favor annexation is greater than 72%.
To determine if there is sufficient evidence to support the mayor's claim, a hypothesis test should be performed. A common approach is to use a one-sample proportion test. This test compares the proportion of residents who favor annexation in a sample to the hypothesized proportion of 0.72.
Assuming a significance level of 0.05, if the p-value is less than 0.05, then there is sufficient evidence to reject the null hypothesis and conclude that the proportion of residents who favor annexation is greater than 72%.

If all of the diagonals are drawn from a vertex of an n-gon, how many triangles are formed?A) n - 2B) n - 1C) nD) n + 1
Answers
The correct answer to the given question about all of the diagonals drawn from a vertex of an n-gon is option b) n-1
If all of the diagonals are drawn from a vertex of an n-gon, the number of triangles formed is equal to the number of non-diagonal sides of the n-gon. To see why, imagine selecting a vertex of the n-gon and drawing all of the diagonals from that vertex. Each diagonal connects that vertex to a non-adjacent vertex of the n-gon, which splits the n-gon into a series of triangles. The total number of triangles formed is equal to the number of non-diagonal sides of the n-gon, because each non-diagonal side forms one triangle with the selected vertex and one of its adjacent vertices. An n-gon has n sides, so the number of non-diagonal sides is equal to n - 3. This is because each vertex is connected to two adjacent vertices, so there are n - 2 diagonal sides emanating from the selected vertex, and the remaining n - 2 sides are non-diagonal. In addition, there are three sides at the selected vertex that are not counted as non-diagonal sides, so we subtract 3 from n - 2 to get n - 3. Therefore, the answer is (B) n - 1.
