Cindy says that 1/3 is an irrational number because the fraction form doesn't terminate. Construct an argument to support or refute Cindy's position.

Answers

Answer 1

Answer: It’s not an irrational number because it can be written as a decimal. It is in an infinite decimal but if anything can be written as a fraction it is not a irrational number. :))

Answer 2

Answer:

Final answer:

Cindy's argument is incorrect. 1/3 is a rational number because it can be expressed as the ratio of two integers. The fact that the decimal representation of 1/3 does not terminate does not make it irrational.

Explanation:

Cindy's argument is incorrect. A fraction is considered irrational if it cannot be expressed as the ratio of two integers. In the case of 1/3, it can be expressed as the division of the integer 1 by the integer 3, so it is a rational number. The fact that the decimal representation of 1/3 (0.333...) does not terminate does not make it irrational. Irrational numbers are decimal numbers that do not repeat or terminate, such as π (pi) and √2 (the square root of 2).

Answers

If you would like totransform the phrase 7 copies of the sum of 8 fifths and 4 into a math expression, you can do this using the following steps:

8 fifths ... 8/5

What is the correct classification of 7x2 + 9x + 4? Select one of the options below as your answer:A. monomial B. binomial C. trinomial

Answers

Answer:

The correct classification is trinomial.

Step-by-step explanation:

Given the equation

$7x^2+9x+4$

we have to choose the options.

Monomial is an algebraic expression containing one term, binomial with two terms and trinomial with 3 terms.

Now, the given expression

$7x^2+9x+4$

consisting of 3 terms therefore called trinomial.

Hence, the correct classification is trinomial.

B. binomial

this expression has two terms (whole numbers and a x-term

A car factory produces 100 cars in a day. If c is the total number of cars produced in d days, which equation represents the number of cars as a function of the number of days?. a.d = f(c) = 100c.
b.d = f(c) = 100 + c.
c.c = f(d) = 100d.
d.c = f(c) = 100d.
e.d = f(c) = 100 – d
