The dimensions and number of animals are given for different corrals

Suppose that the corrals are rectangular in shape. The formula of the area of a rectangle is
[tex]\begin{gathered} A=lw \\ l\to\text{ length} \\ w\to\text{ width} \end{gathered}[/tex]Therefore, the areas of the four different corrals are

[tex]\begin{gathered} \frac{A_1}{110}=18.1818\ldots<20 \\ \frac{A_2}{115}=18.2608\ldots<20 \\ \frac{A_3}{125}=19.8<20 \\ \frac{A_4}{110}=20=20 \end{gathered}[/tex]Therefore, the only corral that meets the requirement is corral 4, the answer is option D.
Which proportion describes the relationship between corresponding sides of the triangles?
Answers
Answer: C. WX/RS = 3/6
Explanation:
In the triangle WXY the vertical side is WX, and the horizontal side is XY.
In the triangle RST the vertical side is RS, and the horizontal side is ST.
Since both triangles are similar, this means that their angles have the same measurements, and that there is a propotion or relationship between their sides.
The corresponding sides in this triangle are the following:
WX is a corresponding side with RS
XY is a corresponding side with ST
WY is a corresponding side with RT
Out of the options that we have, the only one that relates two corresponding sides is:
[tex]C\mathrm{}\frac{WX}{RS}=\frac{3}{6}[/tex]This is because as we pointed out, WX ans RS are correponding sides.
Also from the image we see that WX = 3 and RS = 6 wich is correctly placed in option C. Thus C represents the proportion between the two corresponding sides.
Answer: C. WX/RS = 3/6
Find the equation (in terms of xx ) of the line through the points (-4,1) and (3,-2)
Answers
First, find the slope of the line that passes through the given points using the slope formula:
[tex]m=\frac{\Delta y}{\Delta x}[/tex]Next, substitute the value of the slope and the coordinates of one of the given points into the slope-intercept form of the equation of a line to find the y-intercept b:
[tex]y=mx+b[/tex]Compute the value of the slope:
[tex]\begin{gathered} m=\frac{(-2)-(1)}{(3)-(-4)} \\ =\frac{-2-1}{3+4} \\ =\frac{-3}{7} \\ =-\frac{3}{7} \end{gathered}[/tex]Replace m=-3/7, x=-4 and y=1 into the slope-intercept form of the equation of a line:
[tex]\begin{gathered} \Rightarrow1=-\frac{3}{7}(-4)+b \\ \Rightarrow1=\frac{12}{7}+b \\ \Rightarrow1-\frac{12}{7}=b \\ \Rightarrow-\frac{5}{7}=b \\ \therefore b=-\frac{5}{7} \end{gathered}[/tex]Replace m=-3/7 and b=-5/7 to get the equation of the line through the points (-4,1) and (3,-2):
[tex]y=-\frac{3}{7}x-\frac{5}{7}[/tex]Therefore, the answer is:

What is a packaging machine?A packaging machine is defined as the industrial equipment that is used package finished product of food and food products such as juice.
For every case of 36 juice boxes = 0.17 liter of wastes juice
The quantity of juice per box = 0.12 liter
This means that the 36 juice boxes = 36 × 0.12 = 4.32 liters
The quantity of juice that is packaged after the wastes has been removed would be;
= 4.32 - 0.17

Standard Deviation for given set of data is 0.25634797778466.
What is standard deviation?
Standard deviation is a measurement of how evenly distributed a set of numbers is. Since the variance is the squared average of the squared deviations from the mean, it represents the square root of the variance.For instance: To determine the standard deviation, sum all of the numbers inside this data set, divide by the total number of numbers, and the result is the standard deviation.Given that,

Write the numbers that will fill in the eighth row of Pascal’s triangle.
Answers
To answer this question, we're going to use some important properties of the Pascal's triangle.
1) If we number the rows starting at zero, then the kth row has k + 1 elements.
2) If we number the elements on the kth row starting with zero, then the mth element of row k is given by
[tex]\begin{pmatrix}{k} \\ {m}\end{pmatrix}=\frac{k!}{m!(k-m)!}[/tex]Using those two properties, we can answer our question.
We want to know the numbers that will fill in the eighth row, this means our k = 8.
From the first property, we know that we have 9 elements on this row, and they are given by
[tex]\begin{pmatrix}{8} \\ {m}\end{pmatrix}=\frac{8!}{m!(8-m)!},m=0,1,2,\ldots,8[/tex]Plugging each m value on this equation, we have
[tex]\begin{gathered} \begin{pmatrix}{8} \\ {0}\end{pmatrix}=\frac{8!}{0!(8-0)!}=\frac{8!}{8!}=1 \\ \begin{pmatrix}{8} \\ {1}\end{pmatrix}=\frac{8!}{1!(8-1)!}=\frac{8!}{7!}=8 \\ \begin{pmatrix}{8} \\ {2}\end{pmatrix}=\frac{8!}{2!(8-2)!}=\frac{8\cdot7}{2}=28 \\ \begin{pmatrix}{8} \\ {3}\end{pmatrix}=56 \\ \begin{pmatrix}{8} \\ {4}\end{pmatrix}=70 \\ \begin{pmatrix}{8} \\ {5}\end{pmatrix}=56 \\ \begin{pmatrix}{8} \\ {6}\end{pmatrix}=28 \\ \begin{pmatrix}{8} \\ {7}\end{pmatrix}=8 \\ \begin{pmatrix}{8} \\ {8}\end{pmatrix}=1 \end{gathered}[/tex]And those are the values on the eighth row.
Write an equation in slope-intercept form of the line that contains the points in the table.
Answers
Step 1. We are given a table of (x, y) values and we need to select the option that represents the slope calculation.
First, we remember the formula to calculate the slope:
[tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]Where (x1, y1) and (x2, y2) are two points or sets of values given for the line.
Step 2. In the numerator of the slope formula, we have a subtraction between y-values.
In the table, the y-values are:
Therefore, in the numerator of the calculation, we must have a subtraction between two of these numbers. This discards options A, and B.
Step 3. In options C and D we have this:
[tex]C.\frac{9-(-3)}{1-(-2)}[/tex][tex]D.\frac{-3-11}{-2-4}[/tex]In option C, there is a correct subtraction of 9 and -3, but in option D, the correct subtraction would be -3-(-11). Therefore option D is also discarded and the correct answer is C.

Neve has 12 full boxes of jars of slime and 7 loose jars of slime. If Neve has a total of 187 jars of slime, which equation can be used to find the number of jars in each box?
Answers
Answer:
15 jars in each box
Step-by-step explanation:
linear equation:
12*N + 7
Now we know that Neve has 187 jars in total, then we can write:
12*N + 7 = 187
We want to find the value of N, which is the number of jars in each box, so we need to solve the linear equation:
12*N + 7 = 187
12*N = 187 - 7
12*N = 180
N = 180/12 = 15
