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?(1 point)
The approximate length from one corner to an opposite corner of a square park that is 700 feet on a side, using 1.4 for the square root of 2, is 700 * (2-√) feet = 700 * (2-1.4) feet = 700 * 0.6 feet = 420 feet.

To convert 0.72¯¯¯¯¯ to a rational number in simplest form, we can express it as 0.727272..., where the cycle of repeating digits is marked with a bar. This can be simplified as 8/11.
A rational number between 5 and 514 is 513.
$$
7–√ ≈ 7 - 2.6 = 4.4
8–√ ≈ 8 - 2.8 = 5.2
Therefore, a rational number with a denominator of 7 that is between 7–√ and 8–√ is 19/7 in improper fraction form.
A rational number can be defined as any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero. Whole numbers, on the other hand, are non-negative integers (including zero) without any fractional or decimal parts.
Examples:
- All whole numbers are rational numbers. For example, 3 is a whole number and can also be expressed as the rational number 3/1.
- Not all rational numbers are whole numbers. For example, the rational number 2/3 is not a whole number as it is not an integer and has a fractional part.
1) No, not all rational numbers are whole numbers. Whole numbers are a subset of rational numbers, but not all rational numbers are whole numbers. For example, 1/2 is a rational number but not a whole number.
2) Yes, all whole numbers are rational numbers. Since whole numbers can be expressed as fractions with a denominator of 1, they can also be considered rational numbers. For example, 5 can be written as 5/1.
3) An example of a rational number that is not a whole number is 3/4.
4) An example of a whole number that is also a rational number is 2.
Question 1: No, not all rational numbers are whole numbers. Example: 1/2 is a rational number but not a whole number.
Question 2: Yes, all whole numbers are rational numbers. Example: 5 can be expressed as the rational number 5/1.
Question 3: An example of a rational number that is not a whole number is 3/4.
Question 4: An example of a whole number that is also a rational number is 2.
Question 10: A rational number with a denominator of 7 that is between 7–√ and 8–√ in improper fraction form is 12/7.
Question 15: The relationship between rational numbers and whole numbers is that every whole number can also be considered a rational number because whole numbers can be expressed as fractions with a denominator of 1. However, not all rational numbers are whole numbers. For example, 1/2 is a rational number but not a whole number, while 2/1 is a whole number and also a rational number.

811 ÷ 9 = 90 with a remainder of 1.
We can see that the remainder is 1, and it repeats indefinitely after the decimal point. So, the repeating decimal representation of 811 is 90.1111... where the cycle of repeating digits is marked with a bar over the digit 1. Therefore, the expression is 90.1¯¯¯¯¯.
$$
Let's denote x as 0.72¯¯¯¯¯.
Multiplying both sides of this equation by 100 gives us:
100x = 72.7272¯¯¯¯¯
Subtracting the original equation from the above equation eliminates the repeating portion:
100x - x = 72.7272¯¯¯¯¯ - 0.72¯¯¯¯¯
99x = 72
Dividing both sides of the equation by 99 yields:
x = 72/99
The fraction 72/99 can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 9:
x = (72 ÷ 9) / (99 ÷ 9)
x = 8/11
Therefore, the rational number representation of 0.72¯¯¯¯¯ is 8/11 in its simplest form.

Let's calculate the approximate values of 7–√ and 8–√:
7–√ ≈ 7 - 2.65 ≈ 4.35
8–√ ≈ 8 - 2.83 ≈ 5.17
Therefore, a possible rational number with a denominator of 7 between 7–√ and 8–√ can be 29/7 in improper fraction form.
A rational number, such as 3.14, can be written as a fraction with both the numerator and denominator as integers, like 314/100. However, an irrational number, like π, cannot be expressed as a fraction and has a decimal representation that neither terminates nor repeats.
