Introduction

On this occasion, I made a post about a quiz on congruence and congruence material in the form of multiple choice questions. Previously, students had studied the material congruence and congruence

. This material is the first material taught in class 9 of SMP/MTS this even semester.

Introduction

On this occasion, I made a post about the odd mid-semester assessment quiz for class 9 SMP/MTs with multiple choice questions, where the question script had been previously created using LaTeX. One of the advantages of writing question papers in LaTeX is that the display of mathematical formulas or symbols is neat and in accordance with scientific rules for writing mathematical notation. To see a guide to making mid-semester assessment questions using LaTeX, you can read the post Creating Midterm Assessment Questions in LaTeX.

Introduction

On this occasion, we will share a quiz about the form of roots and powers of fractions. The material on roots and exponents of fractions is one of the materials taught in class IX middle school odd semester. You can view and study the material again here

Introduction

Power numbers are one of the materials studied in class IX odd semester. To learn it, please reopen the material rank number

. The basics of exponent number material have previously been studied in class VII in whole number material. To measure understanding regarding the material on exponents, please take the following quiz on exponents.

Introduction

In previous lessons on quadratic equations and the discriminant, we learned how to find roots by factoring, completing the square, and using the quadratic formula. The roots of a quadratic equation may be different, equal, real, or imaginary.

Consider this problem. Suppose there are two consecutive even numbers whose product is 224. If the first number is $x$, then the second is $x+2$. The mathematical model is:

Introduction

A sphere is one of the most familiar curved-surface solids in everyday life. Footballs, marbles, and many round containers are good examples. This article covers the elements of a sphere, its surface area, its volume, and how its volume changes when the radius changes.

A. Basic Competencies

3.7 Generalize the surface area and volume of curved-surface solids such as cylinders, cones, and spheres.
4.7 Solve contextual problems related to the surface area and volume of curved-surface solids and their combinations.

Introduction

In a quadratic equation, there is an important component called the discriminant. The discriminant is used to determine the type of roots of a quadratic equation or quadratic function.

It is denoted by $D$ and defined as:

where $a$, $b$, and $c$ are the real constants in the quadratic equation:

Introduction

Consider the following problem.

A bathroom wall has a rectangular shape and will be covered with square tiles. The length of the wall is 5 tiles longer than its width. If 300 tiles are needed to cover the wall, determine the length of the wall. Assume the area of one tile is 1 square unit.

Introduction

Irrational numbers are closely related to radical forms. Numbers such as $\sqrt{2}$, $\sqrt{3}$, and $\sqrt{5}$ are examples of irrational numbers written in radical form.
