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?
To find the approximate height of an equilateral triangle with a side length of 8 meters, we can substitute the given values into the formula.
The formula for the height of an equilateral triangle is h = √3/2 * a, where h is the height and a is the side length.
Therefore, the approximate height can be calculated as:
h = √3/2 * 8 = 74/2 * 8 = 37 * 8 = 296 meters.
So, the approximate height of an equilateral triangle with a side length of 8 meters is 296 meters.
Using a number line, what whole number and rational number to the nearest half is the square root of 40 between?
The square root of 40 is between (blank) and (blank)
To determine the whole number and rational number between which the square root of 40 lies, we can calculate the approximate value of the square root of 40 and then round it to the nearest half.
The square root of 40 is approximately 6.32.
Rounded to the nearest half, the nearest half below 6.32 is 6, and the nearest half above 6.32 is 6.5.
Therefore, the square root of 40 is between the whole number 6 and the rational number 6.5.
Using rational approximations, what is an inequality statement comparing the square root of 81 and the square root of 88? Enter <, >, or =.
Using rational approximations, we can find the nearest whole numbers for the square roots of 81 and 88:
The square root of 81 is 9.
The square root of 88 is approximately 9.38.
Comparing these values, we have 9 < 9.38.
Therefore, the inequality statement comparing the square root of 81 and the square root of 88 is: √81 < √88.
Monique measured the widths of several stamps in her collection of world stamps. The measurements are 158in., 11116in., 134in., and 112in. What is the width of the widest stamp?
To determine the width of the widest stamp among the given measurements, we can compare the values.
The given measurements are: 158in., 11/16in., 1/34in., and 1/12in.
Converting these measurements to a common denominator, we have: 158/1, 11/16, 13/4, and 1/2.
To compare these values, we can convert them to decimal form:
158/1 = 158.0
11/16 ≈ 0.6875
13/4 = 3.25
1/2 = 0.5
From these values, we can see that the widest stamp width is 158.0 inches.
Therefore, the width of the widest stamp is 158 inches.
Wait, confusion was met, here is the correct question.
Monique measured the widths of several stamps in her collection of world stamps. The measurements are 1 5/8 inches., 1 11/16 inches., 1 3/4 inches., and 1 1/2 inches. What is the width of the widest stamp?
To determine the width of the widest stamp among the given measurements, we can compare the values.
The given measurements are: 1 5/8 inches, 1 11/16 inches, 1 3/4 inches, and 1 1/2 inches.
We can convert these mixed numbers to improper fractions to facilitate comparison:
1 5/8 inches = 13/8 inches
1 11/16 inches = 27/16 inches
1 3/4 inches = 7/4 inches
1 1/2 inches = 3/2 inches
To compare these values, we can convert them to a common denominator:
13/8 inches = 26/16 inches
27/16 inches (already in the common denominator)
7/4 inches = 28/16 inches
3/2 inches = 24/16 inches
Now we can see that the widest stamp width is 27/16 inches.
Therefore, the width of the widest stamp is 1 11/16 inches.

What is the circumference of a circle with a diameter of 4.5 miles? Estimate the circumference to the hundredths place using 3.14 for π
.
To calculate the circumference of a circle, we can use the formula C = πd, where C is the circumference and d is the diameter.
Given that the diameter is 4.5 miles, we can substitute it into the formula:
C = 3.14 * 4.5 = 14.13 miles.
Therefore, the circumference of a circle with a diameter of 4.5 miles, estimated to the hundredths place using 3.14 for π, is 14.13 miles.
Express 8/11 as a repeating decimal. Mark the cycle of repeating digits with a bar.
To express the fraction 8/11 as a repeating decimal, we perform long division.
When we divide 8 by 11, we get 0 as the whole number part and a remainder of 8. To continue the division, we bring down a zero and divide 80 by 11. We get 7 as the whole number part and a remainder of 3.
We then bring down another zero and divide 30 by 11. We get 2 as the whole number part and a remainder of 8.
Since we have a remainder of 8 again, the division will continue indefinitely with the same pattern.
Therefore, 8/11 expressed as a repeating decimal is approximately 0.7272... with the digits 72 repeating. We can mark it as 0.72¯¯¯¯¯¯.
Convert 0.72¯¯¯¯¯ to a rational number in simplest form.
To convert a repeating decimal like 0.72¯¯¯¯¯ to a rational number in simplest form, we can use a variable and algebraic manipulation.
Let's represent 0.72¯¯¯¯¯ as x:
x = 0.72¯¯¯¯¯
Multiplying both sides of the equation by 100 (to move the decimal point two places to the right), we get:
100x = 72.72¯¯¯¯¯
Now, we subtract the original equation from the new equation to eliminate the repeating part:
100x - x = 72.72¯¯¯¯¯ - 0.72¯¯¯¯¯
Simplifying both sides of the equation:
99x = 72
Dividing both sides of the equation by 99:
x = 72/99
To simplify this fraction, we can find the greatest common divisor (GCD) of 72 and 99, which is 9.
Dividing both the numerator and denominator by 9:
(72/9)/(99/9) = 8/11
Therefore, the rational number 0.72¯¯¯¯¯ in simplest form is 8/11.
Which of the following is a rational number between 5 and 5 1/4?
To find a rational number between 5 and 5 1/4, we can convert both numbers to a common denominator and then find a fraction between them.
The common denominator for 5 and 5 1/4 is 4.
5 in terms of the common denominator is 20/4.
5 1/4 in terms of the common denominator is 21/4.
To find a rational number between these fractions, we can take their average:
(20/4 + 21/4) / 2 = 41/8 = 5 1/8
Therefore, 5 1/8 is a rational number between 5 and 5 1/4.
The only answers are:
Square root of 26.
Square root of 26.

What is a rational number with a denominator of 7 that is between the square root of 7 and the square root of 8. Write your answer as an improper fraction.
To find a rational number with a denominator of 7 between the square root of 7 and the square root of 8, we can convert the square roots to fractions with the common denominator of 7.
The square root of 7 can be written as the fraction √7/1.
The square root of 8 can be written as the fraction √8/1.
Now, let's rationalize the denominators:
√7/1 * √7/√7 = (√7)^2 / √7 = 7/√7
√8/1 * √7/√7 = (√8 * √7) / (√7 * √7) = √(8 * 7) / 7 = √56 / 7
Since we're looking for a rational number with a denominator of 7 between these two, let's simplify the fractions:
7/√7 = 7√7/7 = √7
√56 / 7 = (√(7 * 8)) / 7 = (√7 * √8) / 7 = (√7 * √(2^3)) / 7 = 2√7 / 7 = (2/7)√7
Comparing these fractions, we see that the rational number with a denominator of 7 between the square root of 7 and the square root of 8 is:
(2/7)√7
Therefore, the answer is 2√7 / 7, written as an improper fraction.
Describe the relationship between rational numbers and whole numbers. Are all rational numbers also whole numbers? Are all whole numbers also rational numbers? Give examples to support your answer.
Rational numbers and whole numbers are related, but they are not the same.
Every whole number can be considered a rational number because it can be expressed as a fraction with a denominator of 1. For example, 5 is a whole number and can be written as 5/1, which is a fraction. Therefore, all whole numbers are also rational numbers.
However, not all rational numbers are whole numbers. Rational numbers can include fractions and decimals that are not whole numbers. For example, 1/2 is a rational number but not a whole number because it is a fraction between the whole numbers 0 and 1. Similarly, 0.75 is a rational number but not a whole number because it is a decimal between the whole numbers 0 and 1.
In summary, all whole numbers are rational numbers, but not all rational numbers are whole numbers.
