The scale factor is 1/3.
What is the scale factor?
The difference in scale between an original object's scale and a new object that is its representation but is larger or smaller is known as a scale factor. For instance, we can increase the size of a rectangle with sides of 2 cm and 4 cm by multiplying each side by, let's say, 2.
Here, we have
Given: Triangle D has been dilated to create triangle D′.
To find the scalar value, simply choose one side of D and one did of D’ and divide them to find the scalar. We can verify that we have the correct scalar by performing this division on each related edge. Below I will do D to D’ represented like D/D’:
4.8 / 1.6 = 3
4.2 / 1.4 = 3
2.7 / x = 3
Knowing that the scaling for each edge is 3, we can solve for x.
2.7 / 3 = x
0.9 = x
The edges for D are 4.8, 4.2, and 2.7 respectively to D’ scaled by 1/3. So we can determine that the edges for D’ are 1.6, 1.4, and 0.9 respectively to D scaled by 3.
So if we go D’ to D, we scale by 3. If we go D to D’, we scale by 1/3.
Hence, the scale factor is 1/3.

The residual plot shows the residuals for the day of the month and the amount in Kali’s checking account. Which statement best assesses the linearity of the relationship between the day of the month and account balance if the scatterplot appears to be reasonably linear?
A) Because the residual plot has an obvious pattern, and the scatterplot appears linear, it is appropriate to use the line of best fit to predict the account balance based on the day of the month.
B) Because the residual plot has an obvious pattern, and the scatterplot appears linear, it is not appropriate to use the line of best fit to predict the account balance based on the day of the month.
C) Because the residual plot has no obvious pattern, and the scatterplot appears linear, it is appropriate to use the line of best fit to predict the account balance based on the day of the month.
D) Because the residual plot has no obvious pattern, and the scatterplot appears linear, it is not appropriate to use the line of best fit to predict the account balance based on the day of the month.
Answers
The best assessment of the linearity of the relationship between the day of the month and account balance would be "Because the residual plot has no obvious pattern, and the scatterplot appears linear, it is appropriate to use the line of best fit to predict the account balance based on the day of the month."The correct answer is option C.
When assessing linearity, it is important to examine both the scatterplot and the residual plot. The scatterplot is used to visualize the relationship between the variables, while the residual plot helps us assess the appropriateness of a linear model by examining the pattern of the residuals (the differences between observed and predicted values).
If the scatterplot appears reasonably linear, it suggests that there is a linear relationship between the variables. In this case, since the scatterplot appears linear, it supports the use of a linear model to predict the account balance based on the day of the month.
Furthermore, the residual plot is used to check for any patterns or systematic deviations from the line of best fit. If the residual plot exhibits no obvious pattern and the residuals appear randomly distributed around zero, it indicates that the linear model captures the relationship adequately.
Therefore, if the residual plot shows no obvious pattern, it provides further evidence in favor of using the line of best fit to predict the account balance based on the day of the month.
In conclusion, when the scatterplot appears linear and the residual plot shows no obvious pattern, it is appropriate to use the line of best fit to predict the account balance based on the day of the month.

The depth of a local lake averages 38 ft, which is represented as |−38|. In February, it measured 6 ft deep, or |−6|, and in July, it was 25 ft deep, or |−25|. What is the difference between the depths in February and July?
A32 feet
B 31 feet
C 19 feet
D 13 feet
Answers
The difference between the depths in February and July is 31 feet.
How to measure depth?The method of measuring depth depends on what we are trying to measure the depth of. Here are some general methods for measuring different types of depth:
Depth of water: The depth of water can be measured using a sounding device such as a sonar or a simple depth gauge. A sonar uses sound waves to determine the distance from the water's surface to the bottom. A depth gauge is a simple device that measures the distance from the surface of the water to the bottom using a weight and a line.
Depth of a hole: The depth of a hole can be measured using a tape measure or a ruler. Simply insert the measuring device into the hole and measure the distance from the top of the hole to the bottom.
Depth of a trench: The depth of a trench can be measured using a measuring tape or a surveyor's level. Place the measuring device at the edge of the trench and measure the distance from the top of the trench to the bottom.
Depth of a pool: The depth of a pool can be measured using a pool depth marker or by using a measuring tape. A depth marker is usually located on the side of the pool and indicates the depth at various points. Alternatively, you can use a measuring tape to measure the distance from the surface of the water to the bottom of the pool.
Depth of a well: The depth of a well can be measured using a well sounder or a tape measure. A well sounder is a device that sends a signal down the well and measures the time it takes for the signal to bounce back. The time it takes is then used to calculate the depth of the well. Alternatively, a tape measure can be used to measure the distance from the surface of the water to the bottom.
Given, In February, it measured 6 ft deep, or |−6| and in July, it was 25 ft deep, or |−25|.
The difference between the depths in February and July is:
|−6| − |−25| = 6 − (−25) = 6 + 25 = 31
Therefore, the correct choice is B) 31 feet.

\(\frac{-(-7)±\sqrt{(-7)^2 - 4 * 6 * (-20)} }{2(6)}\)
= \(\frac{7±\sqrt{49 + 80 * 6} }{12}\)
= \(\frac{7±\sqrt{49 + 480} }{12}\)

= \(\frac{7±23 }{12}\)
\(\frac{7 - 23 }{12}\) = \(\frac{-16 }{12}\) = -8 / 6 = -4 / 3

Answer:
\(x1 = - \frac{4}{3} \)\(x2 = \frac{5}{2} \)Step-by-step explanation:
\(6 {x}^{2} - 7x = 20\)
Move constant to the left and change its sign
\( {6x}^{2} - 7x - 20 = 0\)
Write -7x as a difference
\(6 {x}^{2} + 8x - 15x - 20 = 0\)
Factor out 2x from the expression
\(2x(3x + 4) - 15x - 20 = 0\)
Factor out -5 from the expression
\(2x(3x + 4) - 5(3x + 4) = 0\)
Factor out 3x + 4 from the expression
\((3x + 4)(2x - 5) = 0\)
When the product of factors equals 0 , at least one factor is 0
\(3x + 4 = 0\)
\(2x - 5 = 0\)
Solve the equation for X1
\(3x + 4 = 0\)
Move constant to right side and change its sign
\( 3x = 0 - 4\)
Calculate the difference
\(3x = - 4\)
Divide both sides of the equation by 3
\( \frac{3x}{3} = \frac{ - 4}{3} \)
Calculate
\(x = - \frac{4}{3} \)
Again,
Solve for x2
\(2x - 5 = 0\)
Move constant to right side and change its sign
\(2x = 0 + 5\)
Calculate the sum
\(2x = 5\)
Divide both sides of the equation by 2
\( \frac{2x}{2} = \frac{5}{2} \)
Calculate
\(x = \frac{5}{2} \)
\(x1 = - \frac{4}{3} \)
\(x2 = \frac{5}{2} \)

Rectangle measures 6 by 4 whereas rectangle b measures 6 by 2. A rectangle has two dimensions: a length and a width that are both perpendicular to it.
How do you determine a rectangle's dimensions?How to calculate a rectangle's dimensions: The perimeter equation can be expressed in terms of one of the following dimensions as follows: P = 2(a+b) b = P/2−a The equation for the area (A) plus the following one is as follows: The equation for area is A = ab.
We are given a square of 36 square centimeters.
The square's size will be 6 cm as a result.
Two rectangles are created by dividing the square into two equal-sized pieces.
Let the rectangles' measurements be 6*a and 6*b. Consequently, we can establish the ratio.
Moreover, we can set the combined area of rectangles equal to the area of square to form another equation:
Using substitution method, we can solve for 'a' and 'b' as shown below:
And
Therefore, dimensions of the two rectangles are 6x4 and 6x2, respectively.

Answers
If an O proposition is true, its corresponding I proposition must also be true.
If an O proposition is true, according to the square of opposition, the truth-values of the corresponding A, E, and I propositions are as follows:
1. A Proposition: The A proposition will be false.
This is because A and O propositions are contradictories, meaning if one is true, the other must be false.
2. E Proposition: The E proposition's truth-value cannot be determined from the O proposition alone, as E and O propositions are called "sub contraries."
This means that they can both be true at the same time, but they cannot both be false at the same time.
