The result of which expression will best estimate the actual product
prisoha [69]

Answer:

The answer is,

(-1) \times \frac {1}{2} \times (-1) \times (1)

Step-by-step explanation:

The given product is,

\frac {-4}{5} \times \frac{3}{5} \times \frac{-6}{7} \times \frac {5}{6}

= \frac {12}{35}

\simeq 0.3429 ---------------------(1)

Now, the first product to compare is,

(-1) \times \frac {1}{4} \times (-1) \times (-1)

= - 0.25 ----------------------------(2)

The second product to compare is,

(-1) \times \frac {1}{2} \times (-1) \times (1)

= 0.5 ------------------------(3)

The 3rd product to compare is,

\frac {-4}{2} \times \frac {3}{2} \times \frac{-2}{5} \times \frac {5}{2}

= 3 ----------------------------(4)

The 4th product to compare is,

\frac {-3}{4} \times \frac {-3}{4} \times \frac {-1}{5} \times \frac {1}{2}

= \frac {-9}{160}

= 0.05625 -----------------(5)

Comparing all the values , we get (3) is closest to (1).

Hence, we get, the answer is,

(-1) \times \frac {1}{2} \times (-1) \times (1)

Shaneen has $30 to spend on CDs that each cost $10. She wants to calculate n, the number of CDs she can buy with her $30. Which
weqwewe [10]

Answer:

10n \le 30

n \le 3

Step-by-step explanation:

Given

Total = \$30

Cost (each) = \$10

Required

Determine the inequality

Assume she wants to buy n CDs.

If 1 CD costs $10, then n CDs costs 10n.

So, the inequality is:

10n \le 30

<em>We used </em>\le<em> because the amount she wants to spend cannot exceed 30</em>

Divide both sides by 10, to solve for n

n \le 3
