Answer:
0.027 cubic ft/min
Explanation:
Volume of water is V=V(t) Depth of water is h=h(t)
The relationship between V and h is
V=π/3.r2.h
Let
h0= the height of the cylinder = 24ft, r0= the radius of the opening = 10ft.
Since water level (h) rise with respect to flow rate we find an expression for r and substitute into V
r/h = r0/h0= 10/24 = 5/12
r = (5/12) h,
Substitute for r in V
so,
V=1/3.π.(h2)square = 1/3.π. 25/144.(h3)
When
h= 16ft
and dV/dt = 20ft3/min
,
dV/dt =1/3*π*25/144*h3*(dh/dt)
20ft3/min= 1/3*π* 25/144*h3*(dh/dt)
20 = 1/3*π*(16)3.(dh/dt)
Make dh/DT subject of formula
dh/dt=(20*3*144)/(25*π*4096) = 8640/321740.8
=
dh/dt= 0.027 ft3/min
Answer:
Since the Fertile Crescent shared that same latitude with Europe and Asia, the people were able to migrate to new areas and thrive.
Answer:
B. Tracing a sequence of events resulting in a positive outcome
Explanation:
Answer B
Correct. Writers frequently use certain recognizable approaches to develop and organize the reasoning of their arguments. In the opening lines of the passage, the author employs such a method of development when he traces a sequence of events that he believes have culminated in a positive outcome: the First World War happened; the war provided a cautionary example; world leaders have been trying to prevent another outbreak of war; in the end, they succeed in devising the “greatest preventive measures ever adopted by nations.” A method of development provides an audience with the means to trace a writer’s reasoning in an argument. In this case, the author’s approach to organizing his argument suggests that he understands recent peace preservation efforts in terms of a temporal chain of events—one in which each event is linked to the next by a causal logic.

Answer:
B. bargaining
Explanation:
When a person is bargaining they are typically trying to negotiate over something. It is the third stage of DABDA.
Car accelerates whenever its velocity is changed by either changing the speed or the direction of the car's motion. So, even if you are driving your car at a constant speed while turning around a corner, you are still accelerating.
