Question
The circumference of a circle equals pi times the diameter. Using 3.14 to approximate pi, what is the approximate circumference in inches of a circle with a diameter of 12 in.?
To approximate the circumference of a circle with a diameter of 12 inches using the formula C = πd, we can substitute π with 3.14 and the diameter (d) with 12:
C = 3.14 * 12
C ≈ 37.68
Therefore, the approximate circumference of the circle is 37.68 inches.
Question
9/4 is close to the square root of what integer?
The square root of 9/4 is equal to the square root of 9 divided by the square root of 4, which simplifies to 3/2.
So, 9/4 is close to the square root of 2.
Question
Identify which condition is necessary for a number to be rational.
Answer Choices
* It must not be negative.
* It must be able to be expressed as an integer divided by a nonzero integer.
* It must be written as a fraction.
* It must not be an endless decimal.
The condition necessary for a number to be rational is that it must be able to be expressed as an integer divided by a nonzero integer.
So, the correct answer is "It must be able to be expressed as an integer divided by a nonzero integer."
Question
Which of the following is irrational?
Answer Choices
* 52.781654292
* 3.6363636363636363...
* −7 8/37
* √3/4
The irrational number among the options given is √3/4.
Question
Estimate the value of 6×√2. Which of the following choices is the best estimate?
Answer Choices
* 9.8
* 8.4
* 7.1
* 6.4
To estimate the value of 6 × √2, we can approximate the square root of 2 as 1.41 (a commonly used approximation). Then we multiply this approximation by 6:
6 × 1.41 ≈ 8.46
Therefore, the best estimate among the options given is 8.4.
Question
Which statement is true about the square root of 28?
Answer Choices
* It is between 4 and 5, probably closer to 5.
* It is between 5 and 6, probably closer to 5.
* It is between 6 and 7, probably closer to 6.
* It is between 5 and 6, probably closer to 6.
To determine the approximate value of the square root of 28, we can find the perfect square numbers closest to 28. We know that 4^2 = 16 and 5^2 = 25. Since 28 is between these two perfect squares, the square root of 28 will be between 4 and 5.
Therefore, the correct statement is: It is between 4 and 5, probably closer to 5.
Question
Which statement is true about the integer fraction that equals the square root of 2?
Answer Choices
* It does not exist.
* It requires a computer to find it.
* It involves large numbers.
* It is equal to 1.
The correct answer is: It does not exist.
The square root of 2 is an irrational number, meaning it cannot be represented as a fraction of integers. It is a non-repeating and non-terminating decimal.
Are You Sure These Are The Correct Answers
I apologize for any confusion. Let me clarify the correct answer for you.
The statement that is true about the integer fraction that equals the square root of 2 is: It does not exist.
The square root of 2 is an irrational number, and it cannot be expressed as a fraction of integers. It is a non-repeating and non-terminating decimal.
