The height of an equilateral triangle equals 3√2 times the side length. Using 74 for the square root of 3, we can substitute the values into the formula to find the approximate height.

Approximate Height = (3√2) * Side Length
= (3 * 74) * 8
= 222 * 8
= 1776 meters

Therefore, the approximate height of an equilateral triangle with a side length of 8 meters is 1776 meters.

To determine the whole number and rational number that 40−−√ is between on a number line, we can round the square root value to the nearest half.

The square root of 40 is approximately 6.32. Rounded to the nearest half, it becomes 6.5.

Therefore, 40−−√ is between the whole number 6 and the rational number 6.5 on a number line.

To compare 81−−√ and 8–√8 using rational approximations, we can find the decimal or rational approximations of each square root.

The square root of 81 is exactly 9.

To approximate the square root of 8, we can use rational approximations:
√8 ≈ 2.83

Therefore, the inequality statement comparing 81−−√ and 8–√8 is:

9 > 2.83

The circumference of a circle is calculated using the formula C = π * d, where C is the circumference and d is the diameter.

Given a diameter of 4.5 miles and using the approximation of π as 3.14, we can estimate the circumference:

C = 3.14 * 4.5
C ≈ 14.13 miles

Therefore, the estimated circumference of a circle with a diameter of 4.5 miles is 14.13 miles.

To express 811 as a repeating decimal, we divide 811 by the divisor of 999 to obtain the repeating decimal form.

811 ÷ 999 ≈ 0.811811...

In this case, the repeating pattern is 811, so we can express it as 0.8̅1̅1̅.

Therefore, 811 can be expressed as a repeating decimal as 0.8̅1̅1̅.

To convert the repeating decimal 0.72¯¯¯¯ to a rational number in simplest form, we can set a variable equal to the repeating part (72¯¯¯¯¯) and subtract the variable from the whole decimal:

x = 0.72¯¯¯¯
100x = 72.72¯¯¯¯

Now, we subtract the first equation from the second equation:

100x - x = 72.72¯¯¯¯ - 0.72¯¯¯¯
99x = 72
x = 72/99

To simplify the fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 9:

x = (72/9)/(99/9)
x = 8/11

Therefore, 0.72¯¯¯¯ can be converted to the rational number 8/11 in simplest form.

To find a rational number with a denominator of 7 that is between 7–√ and 8–√, we can identify the whole number part and the decimal part of the square roots.

The whole number part of 7–√ is 7, and the decimal part is less than 1.
The whole number part of 8–√ is 8, and the decimal part is also less than 1.

To find a rational number between them with a denominator of 7, we can take the average of these two whole numbers:

(7 + 8) / 2 = 15 / 2

Therefore, a rational number with a denominator of 7 that is between 7–√ and 8–√ is 15/2, which is an improper fraction.

The relationship between rational numbers and whole numbers is that all whole numbers are rational numbers, but not all rational numbers are whole numbers.

To understand this, we need to define rational numbers and whole numbers.

A rational number is a number that can be expressed as the ratio of two integers, where the denominator is not zero.

A whole number, on the other hand, is a non-negative integer, including zero.

All whole numbers can be expressed as the ratio of two integers, where the denominator is 1. For example, 2 can be written as 2/1, which is a ratio of two integers. Therefore, all whole numbers are rational numbers.

However, not all rational numbers are whole numbers. Rational numbers can include fractions and decimals. For instance, 1/2 and 0.5 are rational numbers, but they are not whole numbers because they are not integers.

In summary, all whole numbers are rational numbers, but not all rational numbers are whole numbers.
