most countries in europe follow Christianity and speak a languade derived from indo-europen. this area can be considered a ____?
Talja [164]

Answer:

Europe can be considered as a cultural region.

Explanation:

Europe is part of the Eurasian continent. It has been defined as a separate continent not as all others, but on the basis of culture, religion, and race. While this may come as strange, it is not actually, as almost all ethnic groups are descended from the Aryans, speak Indo-European languages, and follow the same religion (Christianity).

These traits put Europe on the map as a cultural region. Not to be confused though, as these are all general traits, which is in contrast with the high amount of different cultures, languages, and religious fractions throughout Europe. While the continent as a whole can be defined as a cultural region, it has to be mentioned that there are also smaller ethnic groups like the Magyars, Szekely, Finns, Basques, Tartars, etc. that come from different cultural, ethnic, and in some cases religious backgrounds.

adelina 88 [10]

Answer:

$13764 ; $247752 ; $173426 ; $259740

Explanation:

1 white pine = 62 board feets

Density of white pine = 120 trees per acre

Wholesale price per board foot = $1.85

The value per acre of white pines

(Number of board foots per white pine) * (Number of white pines per acre) * (wholesale price per board foot)

(62 * 120 * $1.85) = $13,764

B.) Amount Realized on harvesting 18 acres

Value per acre * 18

$13764 * 18

= $247752

C.)

Amount charged by timber company = 30% of wholesale price

Total wholesale amount realized on 18 acre = $247752

Amount left after paying timber company :

$247752 - (0.3 * $247752)

= $173426.4

= $173426 (nearest dollar)

d.

Amount made now : = $247752

After 10 years :

The value per acre of white pines

(Number of board foots per white pine) * (Number of white pines per acre) * (wholesale price per board foot)

(127 * 120 * $1.85 * 18) = $507492

$507492 - $247752 = $259740
