Dan, Juan, and Thuy are sharing 4 oranges equally. How
many oranges does each person have?
Answers
Answer: 1 1/3
Step-by-step explanation: To find this answer, we simply divide the people by the oranges. So, 4 / 3 is 1.3333333333333...... We round this to about 1.3. So, that as a fraction is 1 1/3. So, each person gets 1 1/3. To check, we multiply 1 1/3 by 3 (people) and we get 4. I hope this helped!

Which function describes a transformation that maps trapezoid FGHI to trapezoid F'G'H'I'?
Answers
The function that maps the trapezoid FGHI to trapezoid F'G'H'I' is
B. (x, y) → (1/2 x - 5, 1/2 y)
How to determine the transformation?The change of shape as seen in the two objects was reduction in size and linear movement to the left.
The reduction is size is reduction by half and this is dilation with a scale factor of 1/2. This is represented by the formula
(x, y) → (1/2 x, 1/2 y)
Then linear movement to the left is translation to the left and this id 5 units to the left. The formula to show this as below
(x, y) → (1/2 x - 5, 1/2 y)

here are the weights (in pounds) of 20 steers on an experimental feed diet: 183 140 136 142 172 153 172 156 70 167 192 166 113 171 159 129 112 135 174 155 where is the center of the distribution of this data set?
Answers
The centre of the distribution of weights of the 20 steers is 149.85 pounds.
The centre of a distribution of data can be described as the central tendency or typical value of the data. The most common measure of central tendency is the mean, which is calculated by summing all the values in a data set and dividing by the number of values.
To calculate the mean weight of the 20 steers, we can use the following formula:
mean = (183 + 140 + 136 + 142 + 172 + 153 + 172 + 156 + 70 + 167 + 192 + 166 + 113 + 171 + 159 + 129 + 112 + 135 + 174 + 155) / 20
mean = 2997 / 20
mean = 149.85
Therefore, the centre of the distribution of weights of the 20 steers is 149.85 pounds.

a rectangular storage container with an open top is to have a volume of 14 cubic meters. the length of its base is twice the width. material for the base costs 13 dollars per square meter. material for the sides costs 6 dollars per square meter. find the cost of materials for the cheapest such container.
Answers
The cost of the side material is $148.91, the cost of the base material is $73.67 and the cheapest cost of material is $222.58 and this can be determined by using the arithmetic operations.
Let the width of the rectangular storage container be 'x' then according to the given data the length is '2x' and let the height of the container be 'h'.
The base area of the rectangular storage container is given by:
Base Area = 2x² -- (1)
The side area of the rectangular storage container is given by:
Side Area = 2(2x)h + 2xh
= 6xh -- (2)
Now, the volume of the rectangular storage container is given by:
Volume = l x b x h
14 = 2x²h
h = 7/x²
Now, the cost is given by:
C(x) = 13(2x²) + 6(6xh)
C(x) = 26x² + 252/x
To minimize C(x), differentiate the C(x) with respect to x.
C'(x) = 52x - 252/x² --3()
52x - 252/x² = 0
x³ = ∛(63/13)
Now, differentiate equation (3) with respect to x.
C''(x) = 52 + 504/x³
C"( ∛(63/13) ) = 156 > 0
Therefore, ∛(63/13) is the point of minima.
Now, the cost of the base material is:
= 13 x 2 (62/13)^(2/3)
= $73.67
Now, the cost of the side material is:
= 252/(∛(63/13))
= $148.91
Therefore, the total cost is given by:
= 73.67 + 148.91
= $222.58
Hence, the cheapest cost of material is $222.58

The product of (2 + 7i)(2 − 7i) is (B) 53. It can be written in the form of a + bi as 53 + 0i.
What are Complex Numbers?A complex number is formed by multiplying a real and an imaginary number.
Complex numbers are denoted by the symbol z and have the formula a + ib.
Both a and b are real numbers here.
The real component is denoted by Re(z), while the imaginary component is denoted by Im (z). As a result, 'ib' is an imaginary number.
Here, we have the given expression, (2 + 7i)(2 − 7i) ------(1)
We know that, (a+b)(a-b) = a² - b²
Using the above formula, we get (1) as
(2 + 7i)(2 − 7i) = (2)² - (7i)²
⇒ (2 + 7i)(2 − 7i) = 4 - 49i²
Since, i² = -1, we get
(2 + 7i)(2 − 7i) = 4 - (-49)
Solving, we get
(2 + 7i)(2 − 7i) = 4 + 49

the diagram shows two joined rectangles the total area of the compound shape ABCDEF is 36cm^2
Answers
Note that given the diagram showing joined Rectangles with the total area of the compound shape given as: ABCDEF = 36cm², the value of length AB = 4.5 or 9/2
What is a compound shape?A compound form is created by combining simple shapes. It's also known as a "composite" or "complex" form.
To solve for the value of AB, lets start form the given:
Given that:
The area of the shape ABCDEF is 36 square centimeters.
From the given figure:
In the smaller rectangle, length of sides AB is x and BC is (2-4) cm.
In the larger rectangle, length of the sides DE is (x-2) and EF is 3x cm.
thus the area if the Smaller Rectangle is:
A(Small) = x(x-4)
= x² - 4x
The area of the larger rectangle will be:
A(Large) = 3x(x-2)
= 3x² -6x
The total area of the shape will be:
A(Small) + A(Large) = 36
X²-4x+3x²-6x = 36
⇒ 4x² - 10x - 36 = 0; Divide both sides by 2
⇒2x² - 5x - 18 = 0
solving the above using the factoring method, we have:
⇒2x2-5x-18=0
⇒2x2-9x+4x-18=0
⇒x(2x-9)+2(2x-9)=0
⇒(2x-9)(x+2)=0
⇒(2x-9)=0or(x+2)=0
⇒ 2x = 9or x= -2
Thus, x = 9/2 or -2
Since the value of AB cannot be a negative value, thus the correct answer is: 9/2 or 4.5

8. Value Hardware sells 3-in. finishing nails for 0.99/lb and 2-in finishing nails sell for $1.39/1b. Toni needs 5 lb of nails. If his bill totals $6.15, how many pounds of each size did he buy?
Answers
Answer:
This algebraic problem can be solved by setting up a system of equations. For example, let x be the number of pounds of 3-inch nails that Toni buys, and y be the number of pounds of 2-inch nails that Toni buys. We know that x + y = 5 (since Toni believes a total of 5 pounds of pins) and that 0.99x + 1.39y = 6.15 (since that is the total cost of the nails). We can solve for one of the variables using one equation and then substitute that value into the other equation.
Solving for x in the first equation: x + y = 5
x = 5 - y
Substituting this into the second equation: 0.99(5 - y) + 1.39y = 6.15
4.95 - 0.99y + 1.39y = 6.15
4.95 = 0.4y + 6.15
-1.2 = 0.4y
y = -3
Since the number of pounds of nails cannot be harmful, we know that this solution is not possible. We can check by plugging in y = 3 (possible) into the first equation and seeing that x + 3 = 5, so x = 2.
Hence, Toni bought 2 lb of 3-inch nails and 3 lb of 2-inch nails.

Answers
We Disagree with the statement that "" If i prove that an algorithm takes O(n²) worst-case time, is it possible that it takes O(n) on some inputs" because if the algorithm is proven to take O(n²) time in the worst-case, it is likely to take even more time on many inputs.
The "big-O" notation provides an upper bound on the growth rate of a function, and is used to describe the asymptotic behavior of an algorithm as the size of the input grows to infinity.
If an Algorithm is proven to take O(n²) time in the worst-case, it means that the running time grows quadratically as the size of the input increases.
It is not likely that the same algorithm will take O(n) time on some inputs because the big-O notation provides an upper bound, and O(n) represents a much faster growth rate than O(n²).
Therefore , O(n²) represents the "worst-case" scenario, so any scenario where the algorithm runs faster is not considered .

To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing calculator, but he could only see one line.

A rational expression seems to be undefined when ever the denominator is zero.
How does an expression becomes undefined?A rational expression seems to be undefined when its denominator becomes zero. Set the denominator to zero and solve the resulting equation to find the values that make a rational expression undefined.An expression in mathematics that has no meaning and thus does not have an interpretation. In the field of real numbers, for example, division by zero is undefined.Here given expression, 5/(x - 10)
The expression becomes undefined when denominator becomes 0.
So here, if x = 10 then the denominator becomes 0.
That is 5/10-10
= 5/0
which is undefined, when x = 10.
Given expression, 15/(y² + 4)
To a expression to be undefined denominator has to be 0.
But here denominator cannot become zero.

5. The set V = {(x, y): 0, y ≥ 0}, together with the usual operations in R2, is not a vector space. Of the ten axioms that must hold for a vector space, give specific examples showing that two of them do not hold.
Answers
Two of the axioms that do not hold for the set V with the usual operations in R2 are the existence of additive inverses and distributivity of scalar multiplication over addition.
Additive Inverses: For a vector space, every vector has an additive inverse, meaning that there exists a vector in the set such that their sum is equal to the zero vector. However, in the set V, the vector (0, 0) is not an additive inverse of any vector of the form (x, y) where y > 0, since their sum is (x, y) which is not equal to the zero vector (0, 0).Distributivity of Scalar Multiplication over Addition: For a vector space, scalar multiplication must be distributive over addition, meaning that (a + b)v = av + bv for all scalars a, b and all vectors v. However, in the set V, this property does not hold, since if we take a = 1, b = -1, and v = (0, 1), then (a + b)v = (1 + (-1))(0, 1) = (0, 0), which is not equal to av + bv = 1(0, 1) + (-1)(0, 1) = (0, 1) + (0, -1) = (0, 0).To learn more about axioms here:

One-fifth inch = Three-fourths mile
Three-fourths inch = One-fifth mile
Four-fifths inch = 3 miles
3 inches = 12 miles
4 inches = 15 miles
Answers
The scale that Lyle could include on the map is /5 inch = 3/4 mile, 4/5 inch = 3 miles, and 4 inches = 15 miles. Hence, option A, option C and option E is the correct answer.
What is the distance?Distance is calculated as the sum of a person's movement and time.
Let D be the actual distance in miles between any two points, and let d be the distance shown on the map between any two points, measured in inches.
The distance between the location on the map and the real distance is equal to 1/5 of an inch since the scale on the map is 1/5 inch = 3/4 mile.
d/D = (1/5)/ (3/4)
1/5 inch = 3/4 mile
4/5 inch = 3 miles
4 inches = 15 miles
Hence, the scale that Lyle could include on the map is /5 inch = 3/4 mile, 4/5 inch = 3 miles, and 4 inches = 15 miles. Hence, option A, option C and option E is the correct answer.

A flower kiosk is selling roses and carnations that are either red or white. 3/5 of all the flowers are red, 1/3 of all the flowers are roses, and 9/20 of all the roses are white. What percent of all the flowers are white carnations?
Answers
Answer:
25%
Step-by-step explanation:
If 3/5 of the flowers are red, then 2/5 of them are white. Since 9/20 of the roses are white, then 9/20*2/5=3/20 of all of the flowers are white roses. Subtracting the number of white roses from the total amount of white flowers will give us the fraction of how many of the flowers are white carnations. 2/5-3/20=5/20=1/4 of all of the flowers, which is 25% as a percentage.
The percent of all the flowers are white carnations is 255.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. With the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
3/5 of the flowers are red.
2/5 of them are white.
and, 9/20 of the roses are white.
fraction of white roses of all flower
= 9/20 x 2/5
=3/20
Fraction of Flowers that are white Carnations
= 2/5 - 3/20
= 5/20
= 1/4.
Then, the percent of all the flowers are white carnations is
= 1/4 x 100

a right triangle has a hypotenuse with a length of 10cm. one angle of the three in this triangle is 53.1 degrees. what is the length of the side opposite this angle?
Answers
The length of the side opposite this angle of the hypotenuse is 12.51°.
A right triangle consists of the hypotenuse (longest side), the opposite(length of the leg) and the adjacent.
The angle at the corner is 90degrees
In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle. We use special words to describe the sides of right triangles. The hypotenuse of a right triangle is always the side opposite the right angle.
Given that,
Length of the leg = 10cm
angle opposite the side = 53.1 degrees
To get the hypotenuse,
sin θ = opposite/hypotenuse
sin 53.1 = 10/hypotenuse
hypotenuse = 10/sin53.1°
hypotenuse = 10/0.799
hypotenuse = 12.51
Therefore,
The length of the side opposite this angle of the hypotenuse is 12.51°.
