Convert the fraction 3/8 to a decimal and a percent.

3/8 = 0.375 = 37.5%. (Divide 3 by 8 for the decimal; multiply by 100 for the percent.)

What is the difference between a rational number and an irrational number?

A rational number can be written as a fraction a/b of two integers (including terminating or repeating decimals). An irrational number cannot (non-terminating, non-repeating decimal), e.g., π or √2.

What is the difference between an expression and an equation in algebra?

An expression is a combination of numbers, variables, and operations with no equals sign (e.g., 3x + 2). An equation states that two expressions are equal using an equals sign (e.g., 3x + 2 = 11).

In the linear equation y = mx + b, what do m and b represent?

m is the slope (rate of change, rise over run), and b is the y-intercept (the value of y where the line crosses the y-axis, when x = 0).

How is the slope between two points (x1, y1) and (x2, y2) calculated?

Slope m = (y2 − y1) / (x2 − x1), i.e., the change in y divided by the change in x ('rise over run').

What is the difference between a dependent and an independent variable?

The independent variable is the input that is changed or controlled (often x). The dependent variable is the output that responds to or depends on the independent variable (often y).

What is the formula for the area and the circumference of a circle?

Area = πr² and Circumference = 2πr (or πd), where r is the radius and d is the diameter.

State the formulas for the area of a triangle, a rectangle, and a parallelogram.

Triangle = ½ × base × height; Rectangle = length × width; Parallelogram = base × height.

What is the Pythagorean theorem and when is it used?

a² + b² = c², where a and b are the legs and c is the hypotenuse of a RIGHT triangle. It is used to find an unknown side length of a right triangle.

How do you find the volume of a rectangular prism and the volume of a cylinder?

Rectangular prism: V = length × width × height. Cylinder: V = πr²h (area of the circular base times the height).

What is the difference between an acute, right, obtuse, and straight angle?

Acute: less than 90°. Right: exactly 90°. Obtuse: between 90° and 180°. Straight: exactly 180°.

How many degrees are in the interior angles of a triangle and of a quadrilateral?

A triangle's interior angles sum to 180°; a quadrilateral's sum to 360°. (General formula: (n−2) × 180° for an n-sided polygon.)

Define mean, median, and mode.

Mean is the arithmetic average (sum ÷ count). Median is the middle value when data is ordered. Mode is the value that occurs most frequently.

What is the range of a data set and how is it calculated?

The range measures spread; it equals the maximum value minus the minimum value in the data set.

How do you calculate the probability of a single event?

Probability = (number of favorable outcomes) ÷ (total number of possible outcomes). It ranges from 0 (impossible) to 1 (certain).

What is the difference between independent and dependent events in probability?

Independent events: the outcome of one does not affect the other (e.g., two coin flips). Dependent events: the outcome of one changes the probability of the other (e.g., drawing cards without replacement).

What is the difference between inductive and deductive reasoning?

Inductive reasoning moves from specific observations to a general conclusion (pattern-based, probable). Deductive reasoning moves from general premises to a specific, logically certain conclusion.

What were the main causes and the result of the American Revolution?

Causes: British taxation without representation (Stamp Act, Townshend Acts), restrictions on colonial self-government, and events like the Boston Tea Party. Result: the 13 colonies declared independence (1776) and won, forming the United States.

What was the significance of the Emancipation Proclamation (1863)?

Issued by President Lincoln during the Civil War, it declared enslaved people in the Confederate states to be free, shifted the war's purpose toward ending slavery, and paved the way for the 13th Amendment.

What is the difference between the five themes of geography: location, place, region, movement, and human-environment interaction?

Location = where (absolute/relative). Place = physical and human characteristics. Region = areas sharing common features. Movement = flow of people, goods, ideas. Human-environment interaction = how people adapt to and modify their surroundings.

What is the difference between weather and climate?

Weather is the short-term, day-to-day state of the atmosphere (temperature, precipitation) in a place. Climate is the long-term average pattern of weather in a region over many years.

In the social sciences, how do anthropology and sociology differ?

Anthropology studies human cultures, origins, and development—often whole societies across time. Sociology studies the structure, institutions, and behavior of groups within modern society.

What were two major contributions of ancient Mesopotamia and ancient Egypt to civilization?

Mesopotamia: cuneiform writing, the wheel, and Hammurabi's Code (early written law). Egypt: hieroglyphic writing, pyramids/monumental architecture, and advances in calendar and medicine.

What are the three branches of the U.S. federal government and their primary functions?

Legislative (Congress) makes laws; Executive (President) enforces laws; Judicial (courts) interprets laws. They are balanced through checks and balances.

What is the difference between the Declaration of Independence and the Constitution?

The Declaration of Independence (1776) announced separation from Britain and stated natural rights. The Constitution (1787) established the framework, structure, and powers of the U.S. government.

In economics, what is the difference between a need and a want, and what is opportunity cost?

A need is a necessity for survival (food, shelter); a want is something desired but not essential. Opportunity cost is the value of the next-best alternative given up when a choice is made.

What are the layers of the Earth from outermost to innermost?

Crust, mantle, outer core (liquid), and inner core (solid).

Describe the three main types of rock and how each forms.

Igneous: from cooled and solidified magma/lava. Sedimentary: from compacted, cemented sediments (often in layers). Metamorphic: from existing rock changed by intense heat and pressure.

What is the difference between photosynthesis and cellular respiration?

Photosynthesis (in plants) uses sunlight, CO2, and water to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to release energy (ATP), producing CO2 and water. They are essentially reverse processes.

What is the difference between a physical change and a chemical change?

A physical change alters form or state but not the substance's identity (e.g., melting, cutting). A chemical change produces a new substance with new properties (e.g., burning, rusting), often irreversible.

What are the three states of matter and how do their particles behave?

Solid: particles packed tightly in fixed positions (definite shape and volume). Liquid: particles close but able to flow (definite volume, takes container's shape). Gas: particles spread far apart, moving freely (no definite shape or volume).

What is the difference between a scientific observation and an inference?

An observation is information gathered directly through the senses or instruments (a fact about what is seen). An inference is a conclusion or explanation drawn from observations, going beyond the direct data.

What is the difference between an independent variable, a dependent variable, and a controlled variable in an experiment?

The independent variable is what the scientist deliberately changes; the dependent variable is what is measured as the response; controlled variables are kept constant so they don't affect the results.
