a museum wants to use equal rows to arrange the African baskets. which list shows all the different possible arrangements so that all the rows have the same number. Assume that an arrangement such as 4 x 20 is the same as 20 x 4.
Answers
Answer:
(B)1 x 80,2x 40,4 x 20,5 x 16,8 x 10
Explanation:
The number of African Baskets = 80
The list of all possible arrangements so that all the rows have the same number will be a list that contains all the positive product of factors of 80.
Factors of 80 are: 1,2,4,5,8, 10, 16,20,40,80
The list is, therefore:
[tex]1\times80,2\times40,4\times20,5\times16,8\times10[/tex]The correct choice is B.

2( 2 - 7y) - 3y = 6

Complete the proof that the point (-2, V5 ) does or does not lle on the circle centered at the origin and containing the point (0,3). Part 1 out of 4 The radius of the circle is

We will have the following:
*First: We have that the equation of the circle will be given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex]Here (h, k) is the coordinate of the center of the circle and r is the radius of the circle.
*Second: We will replace the center of the circle and determine the radius:
[tex]x^2+y^2=r^2[/tex]*Third: We determine the radius of the circle by using the point given:
[tex](0)^2+(3)^2=r^2\Rightarrow r^2=9\Rightarrow r=3[/tex]*Fourth: We have the following expression representing the circle:

Answers
Two lines are parallel if they do not intersect at any point.
Another way of thinking on parallel lines is: two lines are parallel if they have the same slope.
On the other hand, all horizontal lines have the same slope, which is equal to 0.
Since all horizontal lines have a slope equal to 0, this means that all horizontal lines are parallel.
Therefore, the answer is: yes. All horizontal lines are parallel.

Answers
The equation of the line that goes through the point (5, -1) and is parallel to the given equation is; 3x + 2y = -7.
What is the equation of the line that gOES through the point given and is parallel tomthe given equation?Recall from line geometry that parallel lines have equal slopes.
Therefore, by computing the slope of the equation given as follows; we have;
3x + 2y = 19.
By rearranging the equation in the slope-intercept form; y = mx + c; we have;
y = (-3/2)x + 19/2
Therefore, the slope of both lines is same and is; -3/2.
Therefore, By using the point slope equation of a straight line; (y - y1) = m (x - x1); we have;
(y - (-1)) = -3/2(x - 5)
2y + 2 = -3x - 5
3x + 2y = -7.
Ultimately, the required equation is; 3x + 2y = -7.

Comparison chartsB. SizingC. Missing informationD. Axis and scaling manipulation
Answers
From the given graph, let's determine the tactics which the media outlet used to create the graph.
From the graph, we can see that the scaling of the y-axis was manipulated.
The numbers in the y-axis starts from 8%, while a normal graph is suposed to start from 0%.
Although the graph is correct, but the scaling of the y-axis is misleading. This is because when you look at the graph, you will think there is a major difference between unnemployment before and unemployment after.
Therefore, the tactics the media outlet used to create this graph can be said to be Axis and Scaling manipulation.
Axis and scaling manipulation is a method used in producing misleading graphs to make the data look worse or better than it actually is. This method leads to incorrect conclusions,

End Behavior Graphically
Answers
We will investigate how to determine the end behaviours of polynomial functions.
The function given to us is:
[tex]f(x)=123x^3+9x^4-786x-3x^{5^{}}-189x^2\text{ + 1260}[/tex]Whenever we try to determine the end-behaviour of any function. We are usually looking for value of f ( x ) for the following two cases:
[tex]x\to\infty\text{ and x}\to-\infty[/tex]The most important thing to note when dealing with end-behaviour of polynomial functions is that the behaviour is pre-dominantly governed by the highest order term of a polynomial. The rest of the terms are considered small or negligible when considering end-behaviours of polynomials.
The highest order terms in the given function can be written as:
[tex]f(x)=-3x^5[/tex]Then the next step is to consider each case for the value of ( x ) and evaluate the value of f ( x ) respectively.
[tex]\begin{gathered} x\to\infty \\ f\text{ ( }\infty\text{ ) = -3}\cdot(\infty)^5 \\ f\text{ ( }\infty\text{ ) = -3}\cdot\infty \\ f\text{ ( }\infty\text{ ) = -}\infty \end{gathered}[/tex]Similarly repeat the process for the second case:

concetta had a 2kg bag of flour. she used 180g of flour to make biscotti. how many kilograms of flour are left in the bag?
Answers
Answer
The amount of flour left in the bag = 1.82 kg
Explanation
Concetta had 2 kg of flour.
She uses 180 g of the flour to make biscotti.
We are then asked to calculate how much flour is left in kilograms.
Amount of flour left = (Initial Amount of flour) - (Amount of flour used)
Initial amount of flour = 2 kg
Amount of flour used = 180 g = 0.18 kg
Amount of flour left = (Initial Amount of flour) - (Amount of flour used)
Amount of flour left = 2 - 0.18 = 1.82 kg

Let:

We know that Dale uses four times as much solution A as solution B, meaning
[tex]A=4B[/tex]Now, we know that we will end up with 570 mL of pure alcohol in the final solution. Using the dilution of both A and B (20% means 0.2 and 15% is 0.15) we would have that:
[tex]0.2A+0.15B=570[/tex]We would have the following system of equations:
[tex]\begin{cases}A=4B \\ 0.2A+0.15B=570\end{cases}[/tex]Substituting equation 1 in equation 2 and solving for B :
[tex]\begin{gathered} 0.2A+0.15B=570 \\ \rightarrow0.2(4B)+0.15B=570 \\ \rightarrow0.8B+0.15B=570 \\ \rightarrow0.95B=570\rightarrow B=\frac{570}{0.95} \\ \Rightarrow B=600 \end{gathered}[/tex]Substituting in equation 1 and solving for A:
[tex]\begin{gathered} A=4B \\ \rightarrow A=4(600) \\ \Rightarrow A=2400 \end{gathered}[/tex]This way, we can conclude that 2400 mL of solution A and 600mL of solution B were used.
