<h3>Answer is choice D) 7:8</h3>

==============================================================

Work Shown:

The ratio of the surface areas is 686:896 which reduces to 49:64 when we divide both parts by the GCF 64.

Now apply the square root to both parts to go from 49:64 to 7:8

---------

Here's an example why the square root comes into play. Imagine we had two rectangles where one is 3 by 5 and the other is 6 by 10. The areas of each are 3*5 = 15 and 6*10 = 60. Notice how the ratio of the areas is 15:60 which reduces to 1:4, and then that becomes 1:2 after applying the square root. Furthermore, notice how the 6 by 10 rectangle has dimensions exactly double that of the 3 by 5 rectangle, showing the linear scale factor is 1:2.

David express company was asked to deliver 325 boxes of apples. according the rule, the delivery fee is
Andrew [12]

Answer:

22 boxes were lost.  Look for the happy squirrels.

Step-by-step explanation:

Let x be the number of lost boxes.  David Express should expect to receive  $25 for each of the 325 boxes of apples.  That means:

($25)*(325) = $8125

The loss of a box means that the delivery fee would be forfeited, which would amount to:  x*($25)

But a compensation fee of $75/box also applies, so the total loss to the income would be x*($25+$75) or x*($100).  This would be subtracted from the total expected income of $8125:

Resulting Income:   $8125 - ($100)x = $5925

$8125 - ($100)x = $5925

$8125 - ($100)x = $5925

-100x = -2200

x = 22 boxes were lost.                    Zounds! [A metric term for %$%^&]

===================

<u>Check:</u>  Does the loss of 22 of the 325 boxes result in a total payment of $5925?

Delivered boxes:  (325 - 22) = 303 boxes delivered.  303*$25 = $7575

Penalty of $75 per lost box:  22*($75) = $1650

Result:  $7575 - $1650 = $5925  <u>YES</u>
