____________________Solution :-Given Information :-Fraction 1 ➢ [tex] \sf12 \frac{1}{2} [/tex]Fraction 2 ➢ [tex] \sf -4 \frac{1}{2} [/tex]Operation ➢ Subtraction To Find :-The difference between two fractionsCalculation :-[tex] \sf: \implies \sf12 \frac{1}{2} - ( - 4 \frac{1}{2} ) = \boxed{ ? }[/tex]
Firstly, converting mixed fractions to improper fractions, We get,
[tex] \sf: \implies \frac{25}{2} - ( - \frac{9}{2} ) = \boxed?[/tex]
Now, solving the parentheses, We get,
[tex] \sf: \implies \frac{25}{2} + \frac{9}{2} = \boxed ?[/tex]
Since, We have like terms, We will directly add up the two fractions, We get,
[tex] \sf: \implies \frac{25 + 9}{2} = \boxed?[/tex]
Calculating further, We get,
[tex] \sf: \implies \frac{34}{2} = \boxed?[/tex]
Bringing the fraction to it's lowest terms, We get,
[tex] \sf: \implies \frac{ \cancel{34} \: \: \tiny{7}}{ \cancel2} = \boxed7[/tex]
[tex] \sf :\implies \sf12 \frac{1}{2} - ( - 4 \frac{1}{2} ) = \red{ \boxed{ \bf7 }}[/tex]

What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
An inequality is a mathematical statement which compares two values or expressions using a relational operator, such as less than (<), greater than (>), less than or equal to (≤), greater than or equal to (≥), or not equal to (≠). Inequalities are used to show relationships between quantities or to express constraints or conditions.

Before they graduate from Great Lakes High School, all 12th grade students fill out a survey about their future college plans.
Are you attending an in-state college after high school graduation?
Will you begin college during the summer semester?
The same group of students are asked to answer yes or no to both questions. The students’ responses were recorded on the table below.
Determine the probability that a student will begin college during the summer semester and attend an in-state college.
Determine the probability that a student will begin college during the summer semester given that he is attending an in-state college.
Answers
The probability is P = 0.894
How to get the probabilities?
a) Determine the probability that a student will begin college during the summer semester and attend an in-state college.
The probability is given by the quotient between the number of students that start on summer semester and attend to an in-State college, and the total number of students that start on the summer semester.
The number of students starting on the summer semester is:
178 + 21 = 199
Of these 199 students, 178 will attend to an in-state college, so our probability is:
P = 178/199 = 0.894

We are given a 45°-45°-90° triangle with hypotenuse measuring 18 cm.
Let us assume the following labeling of the diagram, as attached in the answer area.
The two angles here are equal to 45° so two sides of the triangle opposite to the equal angles will also be equal to each other i.e. it is an isosceles triangle.
i.e. The sides XY and YZ will be equal.
Let XY = YZ = x cm

A donkey eats three fifths of a hay bale a week.
How many bales does he eat in 10 weeks?
Answers
Answer:
Step-by-step explanation:
the donkey eats 3/5 of hay bale a week
3/5 x 2 = 6
the donkey eats 6 hay bales in 10 weeks
The amount of bales the donkey eats in 10 weeks is 6 bales.
Given,
A donkey eats three-fifths of a hay bale a week.
We need to find out how many bales he eats in 10 weeks.
How do we compare two quantities?Example:
2 miles in 1 hour
2 miles = 1 hour
To find miles in 4 hours we multiply both sides by 4.
4 x 2 miles = 4 x 1 hour
8 miles = 4 hours
We have,
Donkey eats:
3/5 bales = 1 week ____(1)
In 10 weeks:
Multiply 10 on both sides of (1)
10 x 3/5 bales = 10 x 1 week
6 bales = 10 weeks
Thus the amount of bales the donkey eats in 10 weeks is 6 bales.
