The height of an equilateral triangle equals 3√2 times the side length. Using 74 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 point)
The height of an equilateral triangle equals 3√2 times the side length.
Given that √3 is approximately 1.732, we can substitute the value into the equation.
Approximate height = 3(1.732) * 8 = 24.768 meters.
Given that √3 is approximately 1.732, we can substitute the value into the equation.
Approximate height = 3(1.732) * 8 = 24.768 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?(1 point)
The diagonal of a square equals 2–√ times the side length.
Given that √2 is approximately 1.4, we can substitute the value into the equation.
Approximate length = 2(1.4) * 700 = 1960 feet.
Given that √2 is approximately 1.4, we can substitute the value into the equation.
Approximate length = 2(1.4) * 700 = 1960 feet.
Using a number line, what whole number and rational number to the nearest half is 40−−√ between?(1 point)
40−−√ is between
and
.
40−−√ is between
and
.
To determine the whole number and rational number to the nearest half that 40−−√ is between, we need to find the integers closest to it on a number line.
Approximating 40−−√, which is roughly 6.325, we can identify the whole number to the left and right of it:
To the left: 6
To the right: 7
Next, let's find the rational numbers to the nearest half:
To the left: 6.5
To the right: 7.0
Therefore, 40−−√ is between 6 and 7 on the number line and between 6.5 and 7.0 as rational numbers to the nearest half.

To determine the whole number and rational number to the nearest half that 58−−√ is between, we need to find the integers closest to it on a number line.
Approximating 58−−√ to the nearest whole number, we have:
To the left: 7
To the right: 8
Next, let's find the rational numbers to the nearest half:
To the left: 7.5
To the right: 8.0
Therefore, 58−−√ is between 7 and 8 on the number line and between 7.5 and 8.0 as rational numbers to the nearest half.

Using rational approximations, what is an inequality statement comparing 81−−√ and 8–√8? Enter <, >, or =.(1 point)
The inequality is: 81−−√
8–√8.
The inequality is: 81−−√
8–√8.
To compare 81−−√ and 8–√8 using rational approximations, we can simplify and compare the decimal values.
Approximating the square roots:
√81 is exactly 9.
√8 is approximately 2.828.
Comparing the approximate values:
9 > 2.828
Therefore, the inequality statement is:
81−−√ > 8–√8.
Approximating the square roots:
√81 is exactly 9.
√8 is approximately 2.828.
Comparing the approximate values:
9 > 2.828
Therefore, the inequality statement is:
