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,

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

7 MORE THAN TWICE a number n

Sever21 [200]

Answer:

2n+7

Step-by-step explanation:

7 more than twice n would be:

2n+7

this is because twice n would mean that you'd multiply n by 2, and by 7 more than they mean you would add 7 to that.

Math queztion -8x + 40> -16 =

emmainna [20.7K]

Answer: x < 7

Step-by-step explanation: Just like any of your two-step equations, in this inequality, start by isolating the x term which in this case is -8x by subtracting 40 from both sides.

That leaves you with -8x > -56.

To get x by itself, divide both sides by -8 but watch out.

If you divide both sides of an inequality by a negative,

you must switch the direction of the inequality sign.

So we have x < 7.

zahra earns $80 each day plus a 6% commission on her sale at an appliance store. on friday zahra has $900in sales.how much does

goldenfox [79]

<h3>Zara earned $ 134 on friday including commission</h3>

Solution:

Given that,

zahra earns $80 each day plus a 6% commission on her sale at an appliance store

zahra has $900 in sales

Find the commission amount

commission amount = 6 % of 900

$commission\ amount = \frac{6}{100} \times 900\\\\commission\ amount = 54$

Zara earnings including commission amount = 80 + 54 = 134

Thus Zara earned $ 134 on friday including commission
