Can anyone help with pre- alerba
faust18 [17]

Answer:

\sqrt{x^2} = |x|

Step-by-step explanation:

\sqrt{x^2} = |x|

The radical symbol when used for a square root means the non-negative  square root. You cannot state that sqrt(x^2) = x because x may be negative. That is why you need use the absolute value symbol.

A dealer earns a profit of 8$ per bag of white cement and a loss of 5$ per bag of grey cement.
Natali [406]

Answer :-

  1. loss = <em> </em><em>100</em><em>0</em><em>$</em><em> </em>
  2. 4000

Step by step explanation :-

1#

Profit on 3000 bags of white cement sold = 3000 × 8 = 24000

loss on 5000 bags of grey cement sold = 5000 × 5 = 25000

<u>Alternatively</u><u>:</u><u> </u>

  • Net loss = ( 25000 - 24000 ) = 1000$
  • profit/ loss = $ [3000 × 8 - 5000 × 5 ]
  • $ [24000 - 25000]
  • -1000$

<em>As</em><em> </em><em>the</em><em> </em><em>result</em><em> </em><em>of</em><em> </em><em>transaction</em><em> </em><em>is</em><em> </em><em>negative</em><em>/</em><em> </em><em>loss</em><em> </em>

  • Loss = 1000$

2#

  • Loss on the scale of 6400 grey bags = 6400 × 5 = 32,000

<em>In</em><em> </em><em>order</em><em> </em><em>to</em><em> </em><em>have</em><em> </em><em>no</em><em> </em><em>profit</em><em>, </em><em> </em><em>profit from the </em><em>Cello </em><em>white cement should be 32</em><em>0</em><em>0</em><em>0</em><em>.</em><em> </em>

  • Number of white cement bags to be sold = 32000 / 8 = 4000

<em>4000 why cement bags and 6400</em><em> </em><em>grey</em><em> </em><em>cement</em><em> </em><em> </em><em>bags</em><em> </em><em>are sold in order to have no profit and </em><em>n</em><em>o</em><em> </em><em>loss </em>

<em>Hope</em><em> </em><em>it</em><em> </em><em>helps</em><em> </em><em>~</em>
