Answer:
Explanation:
Question 1:
0.42 repeating is rational. A rational number is any integer, fraction, terminating decimal, or repeating decimal.
11/3 = rational. A rational number is any integer, fraction, terminating decimal, or repeating decimal.
6.25 is a rational number. A rational number is any integer, fraction, terminating decimal, or repeating decimal.
16
= irrational irrational number, any real number that cannot be expressed as the quotient of two integers.
0.01045 is rational. A rational number is any integer, fraction, terminating decimal, or repeating decimal.
= Irrational number because it cannot be expressed as a fraction of two whole numbers and it has no accurate decimal equivalent.
= The square root of 48 is not a rational number, as it cannot be expressed in the p/q form.
= rational. The square root of (16/81) is the same as the square root of 16 divided by the square root of 81. You can divide the fraction inside the radical before or after you calculate the square root. The result will be the same.Here we first calculate the square root of the numerator and the square root of the denominator separately, and then we divide the two: √16 √81 = 4 9 ≈ 0.4444 Alternatively, we first divide 16 by 81 and then do the square root of the quotient:√16/81 ≈ √0.1975 ≈ 0.4444
Question 2:
= irrational. Irrational number because it cannot be expressed as a fraction of two whole numbers and it has no accurate decimal equivalent.
= irrational number because it cannot be expressed as a fraction of two whole numbers and it has no accurate decimal equivalent.
= the square root of 30 is not a rational number. It is an irrational number, as it cannot be expressed in the form of p/q.
= irrational number, as it cannot be expressed in the form of p/q.
= irrational since there is no exact square root for 30 and 5.
Question 3:
= 68 is not an exact square root so it is about 8.24621125124….. about 8.25 or 8.3 or just 8.
