To find the length from one corner to the opposite corner of a square park, we can use the formula mentioned:

diagonal = (2 - √2) * side length

Given that the side length of the square park is 700 feet, we can substitute this value into the formula:

diagonal = (2 - √2) * 700

Now, let's substitute √2 as 1.4:

diagonal = (2 - 1.4) * 700
diagonal = (0.6) * 700
diagonal = 420

Therefore, the approximate length from one corner to an opposite corner of the square park is 420 feet.

To find the height of an equilateral triangle, we can use the formula mentioned:

height = (√3/2) * side length

Given that the side length of the equilateral triangle is 8 meters, we can substitute this value into the formula:

height = (√3/2) * 8

Now, let's substitute √3 as 7/4:

height = (7/4 * 8) / 2
height = (14/4) * 8 / 2
height = (14 * 8) / (4 * 2)
height = 112 / 8
height = 14

Therefore, the approximate height of the equilateral triangle is 14 meters.

To identify the whole number and rational number to the nearest half that √40 lies between, let's calculate the square root of 40 to determine its approximate value:

√40 ≈ 6.324

Now, let's consider the nearest whole number and its respective halves:

5 and 5.5

Since √40 is approximately 6.324, it lies between the whole number 6 and the rational number 6.5 (which is the nearest half).

Therefore, √40 is between 6 and 6.5 on the number line.

To find the whole number and rational number to the nearest half that √58 lies between, let's calculate the square root of 58 to determine its approximate value:

√58 ≈ 7.616

Now, let's consider the nearest whole number and its respective halves:

7 and 7.5

Since √58 is approximately 7.616, it lies between the whole number 7 and the rational number 7.5 (which is the nearest half).

Therefore, √58 is between 7 and 7.5 on the number line.

To compare the square root of 81 (√81) and the square root of 88 (√88) using rational approximations, let's calculate their approximate values:

√81 = 9

√88 ≈ 9.380

Therefore, the inequality statement is:

√81 < √88

To express 8/11 as a repeating decimal, we perform long division:

```
0.72
----------
11| 8.00
77
----
30
22
----
80
77
----
30
22
----
80
77
----
30
```

The remainder repeats after the division, which means the decimal representation of 8/11 is 0.72 with a repeating cycle of 72. So, we can write it as:

8/11 = 0.72̅
Answered by GPT 3.5
To convert the repeating decimal 0.72̅ to a rational number, we can set it up as a fraction and solve for it.

Let's represent the repeating decimal as variable x:

x = 0.727272...

Multiply both sides of the equation by 100 to shift the repeating part to the left side of the decimal point:

100x = 72.727272...

Subtract the original equation from the equation multiplied by 100:

100x - x = 72.727272... - 0.727272...

99x = 72

Divide both sides of the equation by 99:

x = 72/99

We can simplify this fraction by finding the greatest common divisor (GCD) of the numerator and denominator, which is 9:

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

Therefore, the rational representation of 0.72̅ is 8/11.

To find a rational number with a denominator of 7 between √7 and √8, we can consider the fractions with a denominator of 7 and test their values in comparison to √7 and √8.

Let's start with the fraction 1/7 and compare:

√7 ≈ 2.645
√8 ≈ 2.828

1/7 ≈ 0.142

Since 0.142 is less than √7, we can try the next fraction, 2/7:

2/7 ≈ 0.285

Still, 0.285 is less than √7. So, we can proceed to the next fraction, 3/7:

3/7 ≈ 0.428

Now, 0.428 is greater than √7 but less than √8. Therefore, the rational number with a denominator of 7 that lies between √7 and √8 as an improper fraction is:

3/7
