What is a fraction?
If the numerator is bigger, it is referred to as an improper fraction and can also be expressed as a mixed number, which is a whole-number quotient with a proper-fraction remainder.
Any fraction can be expressed in decimal form by dividing it by its denominator. One or more digits may continue to repeat indefinitely or the result may come to a stop at some point.
Cye-Na is starting a juice stand. It takes her 15 minutes to prepare 3 1/4 cups of juice.
So in 15 minutes, she makes 13/4 cups of juice.
So for 1 cup she will take 15/ (13/4) minutes.
For 32 1/2 cup she will take 15 * (65/2)/ (13/4)
= 15*65*4/ 2*13
= 150 minutes.
Which is 2.5 hours

Addison earns a fixed hourly rate working as a sales clerk. If she works on a holiday, she earns a different hourly rate than she earns on a regular day. In one week, she earns $188.50 by working 5 hours on a holiday and 16 hours during regular days. A different week, she earns $254.00 by working 8 hours on a holiday and 20 hours during regular days.
How much more is Addison’s holiday hourly rate than her regular hourly rate?
A$2.00
B$8.50
C$10.50
D$19.00
Option a is correct.
$2 more is Addison’s holiday hourly rate than her regular hourly rate
What are Time and Work?
According to fundamental mathematical concepts, time may be described as the amount of time that a specific activity occurs, whereas work can be described as the collection of actions carried out in order to attain a specific activity or outcome. It should go without saying that time is needed to accomplish a task. It implies that time and work have a certain relationship.
The task completed is calculated as the sum of the number of people participating in the work and the number of days it took to finish. The fundamental time and work equation is W = N X D.
W is the amount of work done.
N is the number of people.
D is the number of days or hours needed.
Let r be the regular rate and h the holiday rate.
Then you can write these two equations:
From the first statement:
188.50 = 5h + 16r
From the second statement:
254.00 = 8h + 20r.
There you have a system of two independent equations with two variables, which you can solve by several methods.
If you multiply the first by 8 and the second by 5, you get:
40h + 128r = 1508
40h + 100r = 1270
Subtract the second equation from the first one:
28r = 238
Divide by 28
r = 238/28 = 8.5
You can use now any of the two original statements to find h
254.00 = 8h + 20r
8h = 254 -20(8.5) = 84
h = 84/8 = 10.5
h - r = 10.50 - 8.50 = 2.00
The holiday hourly rate is $2.00 more than the regular hourly rate.
Hence,
$2 more is Addison’s holiday hourly rate than her regular hourly rate

What is unitary method?
It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary Method
First, let us make a note of the information we have. There are 5 ice-creams.
5 ice-creams cost is $125.
Step 1: Let's find the cost of 1 ice cream.
In order to do that, divide the total cost of ice-creams by the total number of ice-creams.
The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-
creams = 125/5 = 25.
Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams.
The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75.
Finally, we have the cost of 3 ice-creams i.e. $75.

What is maxima and minima ?Calculus maxima and minima are found using the concept of derivatives. Knowing that the derivative concept gives information about the slope/slope of a function, we find the point where the slope is zero. These points are called inflection points/stationary points. These are the points associated with the maximum or minimum (local) values of the function.
Knowledge of maxima and minima is essential for our everyday problems. In addition, this article also explains how to find the absolute maximum and minimum values.
Solvable maximum and minimum arithmetic problems are discussed in this article.
CalculationSuppose the width is x (m), length of the base is 2x (m), the base area is 2x^2 (m^2).
Since the volume is 10 (m^3), the height has to be 10/2x^2 (m) = 5/x^2.
The cost of making such container is
cost of base: 2x^2*15 = 30x^2
cost of sides: (2*2x*5/x^2 + 2*x*5/x^2)*9 = 270/x
The overall cost is hence the sum of the base and the sides: f(x) = 30x^2 + 270/x
The get the minimum,
df(x)/dx = 30*(2x - 9/x^2) = 0
so x = (9/2)^(1/3) = 1.651 (m)

What are polygons?
A closed polygonal chain made up of a finite number of straight-line segments is what defines a polygon in geometry. A polygon can be defined as a region that is circumscribed by a bounding circuit, a plane, or both. The edges or sides of a polygon circuit are its segments.
Solution Explained:
Similar polygons have proportional matching sides and all corresponding angles that are congruent.
Since the polygons' side lengths ensure that they are parallelograms, the congruence of just one pair of related angles is sufficient to guarantee the congruence of all the others.
The ratio of side lengths in the left polygon is 13/8, whereas in the right polygon it is 5.2/2.4, which equals 13/6. The matching sides are NOT proportionate since their ratios are different from one another.

Find the dimensions of the most economical shed.
A storage shed is to be built in the shape of a box with a square base. It is to have a volume of cubic feet.
The dimensions of the most economical shed are height = 10 ft and side 5 ft
Taken data
volume = 250 cubic feet
base costs = $4 per square foot
material for the roof costs = $6 per square foot
material for the sides costs = $2.50 per square foot
to find out the dimensions of the most economical shed solution
let us consider length of side x and height is h
so we can say x²h = 250
and h = 250 / x²
now cost of material = cost of base + cost top + cost 4 side
cost = x²(4) + x²(6) + 4xh (2.5)
cost = 10 x² + 10xh
put here h = 250 / x²
cost = 10 x² + 10x (250/ x² )
cost = 10 x² + (2500/ x )
if we differentiate and we get
c' = 20 x - 2500 / x²
put c' = 0 solve x
20 x - 2500 / x² = 0
x = 5
so we say one side is 5 ft base
and height is h = 250 / x²
h = 250 / 5²
height = 10 ft
Hence the answer is, the dimensions of the most economical shed are height = 10 ft and side 5 ft

Question 3[tex]\begin{aligned}&\textsf{Given}: & \dfrac{1}{5}|x-4|-3&=6\\&\textsf{Add 3 to both sides}: & \dfrac{1}{5}|x-4|&=9\\&\textsf{Multiply both sides by 5}: &|x-4|&=45 \\\end{aligned}[/tex]
Set the contents of the absolute value equal to both the positive and negative value of the number on the other side of the equation, and solve both equations.
[tex]\begin{aligned}\underline{\sf Equation\; 1}&&\underline{\sf Equation\; 2}\\x-4&=45 & x-4&=-45\\x-4+4&=45+4 & \quad \quad \quad x-4+4&=-45+4\\x&=49 & x&=-41\\\end{aligned}[/tex]
Therefore, the solutions are x = -41 and x = 49.
Question 4[tex]\begin{aligned}&\textsf{Given}: & -2(x + 3) &= -2x-6\\&\textsf{Distribute}: &-2x-6&=-2x-6\\&\textsf{Add 6 to both sides}: & -2x&=-2x\\&\textsf{Divide both sides by -2}: & x&=x\end{aligned}[/tex]
Therefore, the solution is all real numbers.
Question 5[tex]\begin{aligned}&\textsf{Given}: & \dfrac{3}{2}+\dfrac{1}{2}x & = 2x\\&\textsf{Subtract $\dfrac{1}{2}x$ from both sides}: & \dfrac{3}{2}&=\dfrac{3}{2}x\\&\textsf{Multiply both sides by 2}: & 3&=3x\\&\textsf{Divide both sides by 3}: & 1&=x\end{aligned}[/tex]
Therefore, the solution is x = 1.
john is $\frac{3}{4}$ the age of james. three years ago, john was $\frac{5}{7}$ the age of james. how old is james?
James is 24 years old.
Let John's age now is J.
Let james's age now is A.
From the question, we have
John is 3/4 the age of james.
J=3/4*A
J=3A/4
Three years ago, John was 5/7 the age of james.
J-3=5/7*(A-3)
J-3=(5A-15)/7
J=(5A-15)/7+3
3A/4=(5A-15)/7+3
21A=4(5A-15)+84
21A=20A-60+84
A=24
James is 24 years old.
Multiplication:
Finding the product of two or more numbers in mathematics is done by multiplying the numbers. It is one of the fundamental operations in mathematics that we perform on a daily basis. Multiplication tables are the main use that is obvious. In mathematics, the repeated addition of one number in relation to another is represented by the multiplication of two numbers. These figures can be fractions, integers, whole numbers, natural numbers, etc. When m is multiplied by n, either m is added to itself 'n' times or the other way around.
