Answer:
B. A mosaic has an area of \frac{3}{4} square foot and a width of \frac{1}{5} foot. What is the length of the mosaic?
Step-by-step explanation:
Mathematic representation of a story
Real-life problems involving calculations usually come as stories. The mathematician must be able to represent them in the mathematics language to solve them.
This is an unusual case where the maths are given, and we must find the equivalent story that generated it.
Recall the area of a rectangular shape of length L and width W is:
A = L*W
If we had the area and wanted to calculate the width or the length, we can solve for the required variable as follows:
\(\displaystyle L=\frac{A}{W}\)
\(\displaystyle W=\frac{A}{L}\)
We are given the division:
\(\displaystyle \frac{3}{4}\div \frac{1}{5}\)
can be the calculation of any of the above-mentioned situations.
Note that in both cases, the area is the dividend or the numerator of the fraction. This leads to preselect only the options that provide an area of 3/4 as part of the data.
Only option B. uses 3/4 as the area of the rectangular shape. As 1/5 is the other dimension of the rectangle, this is the correct answer.
B. A mosaic has an area of \frac{3}{4} square foot and a width of \frac{1}{5} foot. What is the length of the mosaic?
Identify the missing
term(s) in the polynomial
X^3 - 95
A. Both 0x^2 and 0x
B. 0x^2
C. 0x
D. 0x4
E. There are no missing terms
The missing term in the polynomial X^3 - 95 is 0x^2.
Option A (Both 0x^2 and 0x) is the correct answer choice, as 0x represents the missing term with a degree of x (linear term) as well.
In the polynomial expression X^3 - 95, we can observe that there is a missing term with an x^2 degree.
To identify the missing term, we need to consider the standard form of a polynomial expression, which is written in descending order of exponents. In this case, the highest exponent present is x^3, followed by a constant term (-95).
To fill in the missing term, we look for the term with an x^2 degree. Since it is not present in the given expression, we can conclude that the missing term is 0x^2.
Therefore, the missing term in the polynomial X^3 - 95 is 0x^2.
Option A (Both 0x^2 and 0x) is the correct answer choice, as 0x represents the missing term with a degree of x (linear term) as well.

How to find the intersection points?(a) The intersection points of the line and curve are the points where the line and curve meet. Thus, the intersection points are:
(0, -3) and (10, 2)
(b) The integral terms of y which gives the area bound are:
a = -3, b = 2 (These are the y values of the intersection points)
Since we have x = y² + 3y and x = 2y + 6, we can say:
y² + 3y = 2y + 6
y² + 3y - 2y - 6 = 0
y² + y - 6 = 0
Thus, h(y) =
Using a = -3 and b = 2 with h(y) = y² + y - 6, we have the bounded area as:
\(Area = \int\limits^b_a {y} \, dy\)
\(Area = \int\limits^{2}_{-3} {(y^{2} + y - 6}) \, dy\)

The weight of one atom of lithium is: 6.941 atomic mass units.
And we know that:
1 atomic mass unit = 1.661x10^(-24)g
Then the mass of one atom is 6.941 times 1.661x10^(-24)g
m = 6.941*1.661x10^(-24)g = 1.153x10^(-23)g
Then the mass of 1.204x10^24 atoms is 1.204x10^24 times 1.153x10^(-23)g
M = 1.204x10^24 *1.153x10^(-23)g = 1.388x10^(24 - 23) g
M = 1.388x10^1g = 13.88 g

Step-by-step explanation:
A certain spinner has equally sized slices. The adds in favor of landing on a green slice are 7:2. What is the probability of landing on A green slice
Given: The odds in favor of landing on a green slice are 7:2
To Determine: The probability of landing on A green slice
Find the total number of landing slices
Since the ratio given is 7:2. The total number of landing slices would be a multiple of the total ratio. The total ratio is
\(\text{Total ratio=7+2=9}\)Therefore, the total number of equal slices is a multiple of 9
Find the ration of the odds on green slice
The ration of the odds on green slice given that the ratio of the odds in favour of landing on a green slide is 7:2 would be multiples of 7
Find the probability of landing on A green slice
The probability of an event A from a sample space S is
\(\begin{gathered} P(A)=\frac{n(A)}{n(S)} \\ P(A)=\text{Probability of event A} \\ n(A)=\text{ number of element in event A} \\ n(S)=\text{ number of elements in the sample space} \end{gathered}\)The probability of landing on a green slice would be
\(\begin{gathered} P(G)=\frac{n(G)}{n(T_r)} \\ P(G)=\text{Probability of landing on a gre}en\text{ slice} \\ n(G)=\text{ number of multiples of the ration for a gr}een\text{ slice landing} \\ n(T_r)=\text{ number of multiples of the total ratio of the landings} \\ \text{Therefore:} \\ n(G)=7 \\ n(T_r)=9 \\ P(G)=\frac{7}{9} \end{gathered}\)Hence, the probability of landing on a green slice is 7/9

It has taken me 32 minutes to drive 48 km. If the total length of my journey is 146 km and I maintain the same speed, estimate how much longer I will be driving for?
It has taken me 32 minutes to drive 48 km. If the total length of my journey is 146 km and I maintain the same speed, then you can estimate that you will be driving for approximately 65.344 minutes longer to complete the remaining 98 km of your journey.
To estimate how much longer you will be driving for, we can use the concept of proportionality. We know that the time taken to drive 48 km is 32 minutes. Let's use this information to find the time it would take to drive 146 km.
We can set up a proportion to find the time:
(time taken for 48 km) / (48 km) = (time taken for 146 km) / (146 km)
Let's solve for the time taken for 146 km:
(time taken for 146 km) = (time taken for 48 km) * (146 km / 48 km)
Substituting the given values:
(time taken for 146 km) = 32 minutes * (146 km / 48 km)
Calculating the value:
(time taken for 146 km) ≈ 32 minutes * 3.042
(time taken for 146 km) ≈ 97.344 minutes
Therefore, it would take approximately 97.344 minutes to drive 146 km at the same speed.
To estimate how much longer you will be driving for, we can subtract the initial time of 32 minutes from the estimated time of 97.344 minutes:
Additional time = 97.344 minutes - 32 minutes
Additional time ≈ 65.344 minutes

5
-10

-5
-10 +
A. It is constant.
e
B. It is decreasing.
C. It is increasing.
Step-by-step explanation:
so, please look at the graph !
it shows you the answer very clearly.
your do know what it means when it is said x = -1 or x = 1 ?
if not, please know that every function with only one input variable (argument) is usually defined as
y = g(x)
and g(x) is then an expression or a group of expressions defining the calculation of the result value (y) for a given input value (x).
and this function can then be represented by a 2- dimensional graph like this showing all valid pairs of x and y.
to represent the values of x there is a horizontal x-axis (going from left to right potentially from -infinity to +infinity).
and to represent the result values of y there is a vertical y-axis (going from down to up potentially from -infinity to +infinity).
and we are looking at the area of the crossing point of both lines, the origin with the x, y coordinates (0, 0), as this is the area of the usually most interesting behavior of the function, and where it often shows us its behavior it will have for large x far out on the chart.
so, when we say x = -1, look at this horizontal x-axis one unit to the left of the crossing with the y-axis. and now at that point look up or down on the chart where a vertical line would cross the function.
in our case (at least based on the fuzzy image) it seems that crossing will be at y = a little big bigger than 2 (above the x-axus are the positive y values, below the negative y values).
and now for x = 1.
look at the horizontal x-axis one unit to the right of the crossing with the y-axis. and now at that point look up or down on the chart where a vertical line would cross the function.
in our case it seems that crossing will be at y = between 0 and -1.
so, when we go from left to right (x=-1 to x=1), are the functional results increasing, decreasing or constant ?
what does the line do in this segment ?
it goes from upper left to lower right. also indicated by the 2 functional values we have seen : for x=-1 we got a result for y of about +2, and for x=1 we got even a negative result (a little bit below 0).
so, the right answer is, it is decreasing in that interval.
The table represents a linear relationship
X—2 0 4
Y-4 3 1
Which equation represents the table
Y=1/2x+5
y=-1/2x+3
Y=2x-3
Y=-4x+2
The linear relationship illustrated in the provided table can be effectively described by the equation Y = -4x + 2. Option D.
To determine the equation that represents the given table with the values of x and y, we can observe the pattern and find the equation of the line that fits these points.
Given the table:
X: 2 0 4
Y: -4 3 1
We can plot these points on a graph and see that they form a straight line.
Plotting the points (2, -4), (0, 3), and (4, 1), we can see that they lie on a line that has a negative slope.
Based on the given options, we can now evaluate each equation to see which one represents the line:
Y = 1/2x + 5
When we substitute the x-values from the table into this equation, we get the following corresponding y-values: -3, 5, and 6. These values do not match the given table, so this equation does not represent the table.
Y = -1/2x + 3
When we substitute the x-values from the table into this equation, we get the corresponding y-values: 4, 3, and 2. These values also do not match the given table, so this equation does not represent the table.
Y = 2x - 3
When we substitute the x-values from the table into this equation, we get the corresponding y-values: -4, -3, and 5. These values do not match the given table, so this equation does not represent the table.
Y = -4x + 2
When we substitute the x-values from the table into this equation, we get the corresponding y-values: -6, 2, and -14. Interestingly, these values match the y-values in the given table. Therefore, the equation Y = -4x + 2 represents the table.
In conclusion, the equation Y = -4x + 2 represents the linear relationship described by the given table. So Option D is correct.

A, solve the system by
I. Gassian elimination method,
II. LU- decomposition method
III. Gauss- Jacobi method,and
IV. Gauss-seidel method,
I. The solution to the system of equations using Gaussian elimination is x = 1, y = -1, and z = 2.
II. For the LU-decomposition method, we need to have a square coefficient matrix, which is not the case in the given system. Therefore, we cannot directly apply the LU-decomposition method.
III. For this method to converge, the coefficient matrix must be diagonally dominant, which is not the case in the given system. Therefore, the Gauss-Jacobi method cannot be directly applied either.
IV. It requires the coefficient matrix to be diagonally dominant, which is not satisfied in the given system. Hence, the Gauss-Seidel method cannot be directly used.
I. Gaussian Elimination Method:
To solve the system of linear equations using Gaussian elimination, we perform row operations to reduce the system into upper triangular form. The augmented matrix for the given system is:
| 6 2 -1 | 4 |
| 1 5 1 | 3 |
| 2 1 4 |27 |
We can start by eliminating the coefficients below the first element in the first column. To do this, we multiply the first row by a suitable factor and subtract it from the second and third rows to eliminate the x coefficient below the first row. Then, we proceed to eliminate the x coefficient below the second row, and so on.
After performing the necessary row operations, we obtain the following reduced row-echelon form:
| 6 2 -1 | 4 |
| 0 4 2 | -1 |
| 0 0 3 | 6 |
From this form, we can easily back-substitute to find the values of x, y, and z. We have z = 2, y = -1, and x = 1.
II. LU-Decomposition Method:
LU-decomposition is a method that decomposes a square matrix into a product of two matrices, L and U, where L is lower triangular and U is upper triangular.
III. Gauss-Jacobi Method:
The Gauss-Jacobi method is an iterative numerical method to solve systems of linear equations.
IV. Gauss-Seidel Method:
Similar to the Gauss-Jacobi method, the Gauss-Seidel method is an iterative method for solving linear systems.
Therefore, out of the four methods mentioned, only the Gaussian elimination method can be used to solve the given system of linear equations.
