A stock loses 10% of its value on Monday. On Tuesday it loses 20% of the value it had at the end of the day on Monday. What is the overall percent loss in value from the beginning of Monday to the end of Tuesday?
Answer: The overall percent loss is 28%.
Step-by-step explanation: Given that a stock loses 10% of its value on Monday and on Tuesday it loses 20% of the value it had at the end of the day on Monday.
We are to find the overall percent loss in value from the beginning of Monday to the end of Tuesday.
Let x represents the value of a stock at the beginning of Monday.
Then, the value of the stock at the end of Monday is given by
[tex]x-10\%\times x=x-\dfrac{10}{100}x=x-\dfrac{x}{10}=\dfrac{9}{10}x.[/tex]
So, the value of the stock at the beginning of Tuesday is [tex]\dfrac{9}{10}x.[/tex]
Therefore, the value of the stock at the end of Tuesday is given by
[tex]\dfrac{9}{10}x-20\%\times\dfrac{9}{10}x\\\\\\=\dfrac{9}{10}x-\dfrac{20}{100}\times\dfrac{9}{10}x\\\\\\=\dfrac{9}{10}-\dfrac{9}{50}x\\\\\\=\dfrac{36}{50}x\\\\\\=\dfrac{18}{25}x\\\\\\=x-\dfrac{7}{25}x\\\\\\=x-\dfrac{28}{100}x\\\\\\=x-28\%x.[/tex]
Thus, the overall percent loss is 28%.
Write the equation of a line that goes through point (0, 1) and has a slope of 0.
Answer:
Equation of this line is y = 1
Step-by-step explanation:
We have to write an equation of a line passing through (0,1) and slope 0.
Standard equation of a line in slope form is y = mx + c
Where m = slope and c = y intercept.
Since m = 0
so y = c is the equation.
This line passes through (0,1)
so equation will be Y = 1
Equation of this line is y = 1
how to solve a system of three equations using the elimination method
Answer:
1. Write all the equations in standard form, leaving out decimals or fractions.
2. Select the variables to be eliminated; And then you take two of these equations, and you eliminate the variables.
3. Select a different set of two equations and eliminate the same variables as in step 2.
4. Solve two equations containing two variables from steps 2 and 3.
5. Substitute the answer to step 4 into any equation that contains the remaining variables.
6. Check the solution with three original equations.
To solve a system of three equations using the elimination method, pair up the equations, eliminate a variable from each pair, solve for the remaining variable and substitute this value into other equations to find the values of other variables.
Explanation:To solve a system of three equations using the elimination method, the process involves eliminating one variable at a time to eventually have one equation with one variable left, which you can then solve.
Pair up the equations. You can pair the first and second equation together, and then pair the second and third equation together. Eliminate one variable from each pair. This can be done by adding or subtracting the equations. For instance, if you have these equations: Qd = 16 - 2P, and Qs = 2 + 5P, subtracting the second equation from the first gives you Qd - Qs = 14 - 7P, thus eliminating the P variable. Solve for the remaining variable. This usually involves rearranging the equation and solving for the variable in question. Once you obtain the value for one variable, substitute this value into the other equations so as to solve for the other two variables. Learn more about Solving Systems of Equations here:

Helen recorded the number of tomatoes on each of her tomato plants and then arranged the numbers from smallest to largest.
The number of tomatoes on each plant were 5, 5, 5, 6, 9, 10, 10,10, 10, and 10. The mean number of tomatoes was 8.
What is the mean absolute deviation?
0.0
2.0
2.2
4.4
Answer:The last experimental design is the best of the options: 'Compare the average number of
tomatoes that are produced by 10 tomato plants that are grown in clay soil to
the average number of tomatoes that are produced by 10 tomato plants that are
grown in sandy soil''.
The first two experimental designs measure the growth of
tomato plants, which is not necessarily related to the yield of tomatoes. The
third experimental design compares the tomato yield of the two
soils with only one plant grown in each soil. Obviously, the result obtained
from this experiment would be statistically weak. The last experimental design
compares tomato yield and also uses a larger number of plants in each soil
type, so the results obtained would be of slightly greater statistical
significance.
Step-by-step explanation:
The mean absolute deviation is M = 2.2
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the total number of plants be n
Now , the value of n = 10
And , the number of tomatoes on each plant is given by set A
Now , the value of set A = { 5 , 5 , 5 , 6 , 9 , 10 , 10 , 10 , 10 , 10 }
So , the total number of tomatoes = 5 + 5 + 5 + 6 + 9 + 10 + 10 + 10 + 10 + 10
The total number of tomatoes = 80 tomatoes
Now , the mean number of tomatoes = 80 / 10 = 8
And , the mean deviation is M
where M = 1/10 [ ( 8 - 5 ) + ( 8 - 5 ) + ( 8 - 5 ) + ( 8 - 6 ) + | ( 8 - 9 ) | + 5( 10 - 8 )
M = ( 1/10 ) [ 3 + 3 + 3 + 2 + 1 + 5 ( 2 ) ]
M = ( 1/10 ) [ 22 ]
M = 2.2
Therefore , the value of M is 2.2
Hence , the mean deviation is 2.2

What is the measure of each of the two angles formed by the bisector of the diagonal of a rhombus if the original angle measures 58 degrees?
Answer: 29 degrees is the answer
Step-by-step explanation:
The bisector is the line that divides the angle, and rhombus diagonally. So, basically you're just dividing 58 in half. Which is 29 degrees.
The measure of each of the two angles formed by the bisector of the diagonal of a rhombus will be 29 degree.
What is angle ?Angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
We have,
A Rhombus with one of its angle equal to 58°.
Now,
Bisector of an angle, divides an angle into two equal parts.
So,
From the above mentioned definition,
i.e.
[tex]=\frac{58}{2} = 29^0[/tex]
So, the measure of each angle is 29°.
Hence, we can say that the measure of each of the two angles formed by the bisector of the diagonal of a rhombus will be 29 degree.

What is the vertex of x^2 -10x + 21
Answer:
(5, - 4)
Step-by-step explanation:
Given a quadratic in standard form : ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
x² - 10x + 21 ← is in standard form
with a = 1, b = - 10, so
[tex]x_{vertex}[/tex] = - [tex]\frac{-10}{2}[/tex] = 5
Substitute x = 5 into the quadratic for the corresponding value of y
y = 5² - 10(5) + 21 = 25 - 50 + 21 = - 4
vertex = (5, - 4)

When converting from inches to feet , the measurement in inches,m, of an object varies directly with its measurement in feet, f, with the constant of variation being 12. What is the equation relating these two quantities?
Answer:
m = 12f
Or
m/12 = f
Step-by-step explanation:
The conversion from inches to feet involves a constant factor of variation which is 12. Inches is a smaller unit while feet are obtained by dividing the inches with 12.
As we know,
1 foot = 12 inches
Given in the question:
m = measurement in inches
and
f= measurement in feet
Hence the equation will be:
m = 12f
Or
m/12 = f ..

Using the prime factor method, find the lowest common multiple of 20 and 12.
Answer:
lcm = 4
Step-by-step explanation:
20 = 2 × 2 × 5 ← product of prime factors
12 = 2 × 2 × 3 ← product of prime factors
The lowest common multiple (lcm) = 2 × 2 × 5 × 3 = 60
Answer:
60
Step-by-step explanation:
First, break down each of the numbers into their prime factors.
20 = 2² x 5
12 = 2² x 3
To find the LCM, underline each of the prime numbers. If there is a repeated prime number, underline the one with the largest possible value. For example, if there is 3² and 3³, underline the second one. In this case, the values are the same, so just underline one.
20 = 2² x 5
12 = 2² x 3
Next, multiply all the underlined numbers.
LCM (20, 12) = 2² x 5 x 3 = 60

For the graph will you have a empty or colored in circle?
If the symbol is ≥ or ≤ then the circle will be colored in. This represents that the number the circle is on is included.
If the symbol is > or < then the circle will be empty. This represents that the number the circle is on is NOT included.
Which direction will the ray go?
If the variable is LESS then the number then the arrow will go to the left of the circle.
If the variable is MORE then the number then the arrow will go to the right of the circle.
In this case your inequality is:
3 ≥ q OR q ≤ 3
aka 3 is greater then q OR q is less then 3
This means that the graph will have an colored circle and the arrow will go to the left of 3. Look at image below.

Compare the graph of f (x) with the graph of k (x) = 2 (x-8)2
The graph of k(x)=2(x-8)², a quadratic function, will be an upwards-opening parabola with a vertex at (8,0). To compare it with the graph of f(x), we need more details about f(x), which could be linear, quadratic, or a different type of function entirely. The comparison can focus on attributes like shape, orientation, position, steepness, continuity, differentiability, or periodicity.
Explanation:The function k (x) = 2 (x-8)² is a quadratic function where 2 is the coefficient, and 8 is the amount that the graph is shifted to the right in the x coordinate. This graph will be a parabola that opens upwards, with a vertex at the point (8,0) due to the transformation in the x term (x-8).
To compare the graph of f(x) with the graph of k(x), we first need to understand the characteristics of f(x). For example, if f(x) is also a quadratic function, we can compare their shapes, orientations (upward or downward opening), positions (based on vertex and line of symmetry), and steepness (determined by the absolute value of the coefficient -- in this case, 2).
If f(x) is a linear function, it will be a straight line and we can compare the orientation, steepness (slope), and position (y-intercept). Or if f(x) is a different type of function entirely, the comparison will focus more generally on attributes like continuity, differentiability, periodicity, etc. Therefore, without additional details about f(x), a complete comparison isn't possible.
