It is an integer but not a whole number.
It is an integer but not a whole number.
It is both an integer and a whole number.
It is both an integer and a whole number.
It is an integer but not a rational number.
It is an integer but not a rational number.
It is a whole number but not an integer.
The correct answer is: It is both an integer and a whole number.
What is a number that is a whole number but not a natural number?
A number that is a whole number but not a natural number is zero (0). Natural numbers start from 1 onwards, so they do not include zero. However, zero is still considered a whole number because it is not a fraction or a decimal.
A sign in a gas station advertises gas at the rate of $3.39 9/10 per gallon. How many dollars does a gallon cost, writing the price strictly as a decimal?

The correct answer is: fractions.
Fractions are always rational numbers because they can be expressed as the quotient of two integers.
The height of an equilateral triangle equals 3√/2 times the side length. Using 7/4 for the square root of 3, what is the approximate height in meters of an equilateral triangle with a side length of 8 meters?(1
To find the height of an equilateral triangle, you can use the formula height = (sqrt(3)/2) * side length.
Given that we will use 7/4 as the approximation for the square root of 3, we can substitute it into the formula:
height = (7/4)(8) = 14 meters.
Therefore, the approximate height of the equilateral triangle with a side length of 8 meters is 14 meters.
The diagonal of a square equals 2–√ times the side length. Using 1.4 for the square root of 2, what is the approximate length in feet from one corner to an opposite corner of a square park that is 700 feet on a side?
To find the length of the diagonal of a square, you can use the formula diagonal = (2 - √2) * side length.
Given that we will use 1.4 as the approximation for the square root of 2, we can substitute it into the formula:
diagonal = (2 - 1.4)(700) = 0.6 * 700 = 420 feet.
Therefore, the approximate length from one corner to an opposite corner of the square park with a side length of 700 feet is 420 feet.
