How you can predict the way your current health decisions will affect your health in the future?
daser333 [38]
In my case, I know from experience and heredity that for example my father died of a second heart attack at least partly because of his high cholesterol. The high cholesterol was related to his high metabolism so that he ate a lot of eggs and bacon when young so that probably produced a lot of bad cholesterol. Myself I also have a tendency to high cholesterol and was warned by my dad's doctor to watch it so consequently I mostly avoid dairy products and egg yolk and beef (red meat) and am mostly able to control it that way with diet so haven't had a heart attack yet.

Weekly rental= 30800

Direct labor= ($14*8 hours*5workes)*5 days= 2800

Total fixed costs= $33,600

Unitary fixed costs= total fixed costs/ Q

7=33600/Q

Q= 4800 units

B) Now Q= 6600

Buy= 6600*22= $145,200

Make= 6600*15 + 33600= $132,600

Which of the following best describes why German firms were nationalized after World War II?
Akimi4 [234]

Answer:

<u>D. Happenstance.</u>

Explanation:

The fact that German firms were nationalized has often been regarded as mere happenstance; meaning it just occurred based on the circumstances they were in immediately after World War II.

It thus encompasses several factors such as the cost of operations, changes in government, etc, not just one factor.
