Step-by-step explanation:
Given
no of houses that can be served by water is directly Proportional to the square of diameter
where k =constant
10 cm diameter can supply 40 houses
-----------1
For d=30 cm Pipe
-------------2
divide 1 & 2
(b)for N=1440 houses
----------------3
Answer: $11,839.16
<u>Step-by-step explanation:</u>
Use the compounded annually formula: , where:
- A is the accumulated amount (total amount)
- P is the principle (amount invested)
- r is the interest rate (in decimal form)
- t is the time (length of time the principle amount was invested)
use a divider to find the length of the middle line then use
Answer:
$1.60
Step-by-step explanation:
i really dont know
Find the volume
volume=hpir^2
d/2=r=16/2=8
1.
hmm, ok, after 1/2 hour or 30 mins
30/5=6
6*1=6, 6 cubic meters
volume=6, solve for height
v=hpir^2
but r=8 all the time, solve for h
6=hpi8^2
6=hpi64
6/(64pi)=h
the depth is
meters or about 0.02984155182973037545666570563235 meters
the depth is about 0.03 meters
2. the full volume is
v=6pi8^2=6pi64=384pi
1 cubic meter every 5 mins so
384pi/1 is how many 5 mininute intervals
so 384pi times 5=total minutes=1920pi minutes or about 6031.8578948924030178482752958966minutes
