What is the formula to calculate the drop in temperature?

• Drop in temperature = Initial temperature - Final temperature.

• Drop in temperature = Final temperature - Initial temperature.

• Drop in temperature = Initial temperature + Final temperature.

• Drop in temperature = Initial temperature * Final temperature.

What is the importance of understanding integers in mathematics?

• They are only used in basic arithmetic operations.

• They are crucial as they form the basis for arithmetic operations and are used in various mathematical concepts.

• They are not important in advanced mathematics.

• They are only relevant in computer programming.

What is the definition of absolute value?

• The absolute value of a number is its distance from zero on the number line, regardless of direction.

• The absolute value of a number is the number itself if it is positive, and its opposite if it is negative.

• The absolute value of a number is always a negative number.

• The absolute value of a number is the square of the number.

Define rational numbers.

• Numbers that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.

• Numbers that cannot be expressed as a fraction.

• Whole numbers and their negatives.

• Numbers that are only positive.

Order the following rational numbers from greatest to least: -0.45, -1/3, 4/5, 0.25, -1/2.

• 4/5, 0.25, -1/3, -0.45, -1/2

• 0.25, 4/5, -1/3, -0.45, -1/2

• -1/3, 0.25, 4/5, -0.45, -1/2

• -1/2, -0.45, -1/3, 0.25, 4/5

What is the relationship between positive and negative numbers?

• Positive numbers are greater than zero, while negative numbers are less than zero; they are opposites on the number line.

• Positive numbers are less than zero, while negative numbers are greater than zero; they are the same on the number line.

• Positive numbers can be negative, while negative numbers can be positive; they are interchangeable on the number line.

• Positive numbers and negative numbers are both equal to zero on the number line.

What does it mean to order numbers from greatest to least?

• Arranging them in ascending order, starting with the smallest number.

• Arranging them in descending order, starting with the largest number.

• Randomly placing the numbers without any specific order.

• Arranging them in a circular pattern based on their values.
