Bearing in mind that a rectangle has a perimeter of length + length + width + width.

P = perimeter
L = length
x=width

P = 2L + 2x
P = 2(L+x)     <==== perimeter of the base of the box.

check the picture below.

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>

in Connecticut the sales tax rate is 6.35% find sales tax amount and the total price of a pillow that costs $ 8.00
Novosadov [1.4K]
If you multiply $8.00 by 6.35% the answer is .508. Round that up to .51. So tax is .51. You add that to $8.00 for a total amount of $8.51.

−−→AB=(xy)<br><br> What values should <br> x<br> and <br> y<br> take?
laiz [17]

The values of x and y are 2 and 0, respectively

The complete question is given below:-

−−→AB=(xy) a line is given in the question from the image given in the question What values should x and y take?

<h3>How do determine the value of x?</h3>

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

From the graph, we have the following highlights:

Point A is at:

A = 2

The point B is located at:

B = 0

The coordinate (x,y) is represented as:

(x,y) = (A,B)

So, we have:

(x,y) = (2,0)

Hence, the values of x and y are 2 and 0, respectively
