To convert the price to a decimal, we can round up the fraction 9/10 to the nearest whole number. Then, we add it to the whole number part of the price.
$3.39 + 1 = $4.39
Thus, a gallon costs $4.39.
$3.39 + 1 = $4.39
Thus, a gallon costs $4.39.

Given that the height of an equilateral triangle is equal to 3√/2 times the side length, and using 7/4 as the approximate value for the square root of 3, we can calculate the height as follows:
height = (3√/2) * side length
height = (3 * (7/4))/2 * 8
To calculate the height, we can simplify the expression:
height = (21/4)*(8/2)
height = (21/4)*4
height = 21
Therefore, the approximate height in meters of an equilateral triangle with a side length of 8 meters is 21.
height = (3√/2) * side length
height = (3 * (7/4))/2 * 8
To calculate the height, we can simplify the expression:
height = (21/4)*(8/2)
height = (21/4)*4
height = 21
Therefore, the approximate height in meters of an equilateral triangle with a side length of 8 meters is 21.

Given that the diagonal of a square is equal to 2–√ times the side length, and using 1.4 as the approximate value for the square root of 2, we can calculate the length from one corner to an opposite corner as follows:
diagonal = (2 - √2) * side length
diagonal = (2 - 1.4) * 700
To calculate the length, we can simplify the expression:
diagonal = 0.6 * 700
diagonal = 420
Therefore, the approximate length in feet from one corner to an opposite corner of a square park that is 700 feet on a side is 420.
diagonal = (2 - √2) * side length
diagonal = (2 - 1.4) * 700

To compare 81−−√ and 8–√8 using rational approximations, we can simplify the expressions:
81−−√ is approximately 9
8–√8 is approximately 6.83
Therefore, the inequality statement comparing 81−−√ and 8–√8 would be:
9 > 6.83
Thus, the inequality is: 81−−√ > 8–√8.
81−−√ is approximately 9
8–√8 is approximately 6.83
Therefore, the inequality statement comparing 81−−√ and 8–√8 would be:
9 > 6.83
Thus, the inequality is: 81−−√ > 8–√8.

811 ÷ 1000 = 0.811
Therefore, 811 can be expressed as the decimal 0.811.
811 ÷ 1000 = 0.811

To convert the repeating decimal 0.72¯¯¯¯¯ to a rational number, we can use the method of repeating decimals.
Let x = 0.72¯¯¯¯¯
To eliminate the repeating part, we can multiply both sides of the equation by a power of 10. Since the repeating part consists of 2 digits, we can multiply by 100:
100x = 72.7272¯¯¯¯¯
Next, we subtract the original equation from the multiplied equation to eliminate the repeating part:
100x - x = 72.7272¯¯¯¯¯ - 0.72¯¯¯¯¯
99x = 72
Dividing both sides by 99, we have:
x = 72/99
To simplify this fraction, we can factor out the greatest common divisor (GCD) of 72 and 99, which is 9:
x = (8 * 9)/(11 * 9)
x = 8/11
Therefore, the decimal 0.72¯¯¯¯¯ can be expressed as the rational number 8/11 in simplest form.
Let x = 0.72¯¯¯¯¯
To eliminate the repeating part, we can multiply both sides of the equation by a power of 10. Since the repeating part consists of 2 digits, we can multiply by 100:
100x = 72.7272¯¯¯¯¯
Next, we subtract the original equation from the multiplied equation to eliminate the repeating part:
100x - x = 72.7272¯¯¯¯¯ - 0.72¯¯¯¯¯
99x = 72
Dividing both sides by 99, we have:
x = 72/99
To simplify this fraction, we can factor out the greatest common divisor (GCD) of 72 and 99, which is 9:
x = (8 * 9)/(11 * 9)
x = 8/11
Therefore, the decimal 0.72¯¯¯¯¯ can be expressed as the rational number 8/11 in simplest form.

To find a rational number with a denominator of 7 that lies between 7–√ and 8–√, we need to find the whole number part of each radical expression.
7–√ is approximately 2.64, which means the whole number part is 2.
8–√ is approximately 2.83, which means the whole number part is also 2.
To find a rational number with a denominator of 7 between these values, we can use the whole number part and the common denominator.
The whole number part is 2, so we will use 2 as the numerator with a denominator of 7, resulting in the improper fraction:
2/7
Therefore, 2/7 is a rational number with a denominator of 7 that lies between 7–√ and 8–√.
7–√ is approximately 2.64, which means the whole number part is 2.

The relationship between rational numbers and whole numbers is as follows:
1. Are all rational numbers also whole numbers?
No, not all rational numbers are whole numbers. Rational numbers are numbers that can be expressed as a fraction of two integers, where the denominator is not zero. Whole numbers, on the other hand, include all natural numbers (positive integers) and zero. Whole numbers do not have a fractional or decimal component.
Example:
3/2 is a rational number but not a whole number because it has a fractional component.
2. Are all whole numbers also rational numbers?
Yes, all whole numbers are also rational numbers. This is because whole numbers can be expressed as fractions with a denominator of 1. Any number with a denominator of 1 is considered a rational number.
Example:
5 is a whole number, and it can also be expressed as 5/1, which is a rational number.
In conclusion, while all whole numbers are rational numbers, not all rational numbers are whole numbers.
