Answer:
0.10865 killograms
Step-by-step explanation:
calculating the liquid mass of ammonia removed through the bottom value from a rigid tank at constant temperature.
Given:
temperature: 
quality : 50% = 0.5
initial mass: 
to find the removed liquid mass first we have to find total volume from which we can find remaining mass. as the tang is rigid the temperature and volume remains constant.
by taking the difference of mass we can determine the mass of liquid removed.
we have two phases at temperature 
with specific volume for liquid 
and specific volume for vapor is 
.
The Volume in the initial state is given by, (Using definition of specific volume)
using 
substituting 
, 
,
we get
finally 
we know the formula to find liquid mass is
density of ammonia is 
inserting the values into the formula we get the value for liquid mass removed through the valve.
the final answer is
A) Commission made last week is $ 288
B) Commissions earned in a year,treating a year as having exactly 52 weeks is $ 14976
<em><u>Solution:</u></em>
From given,
Commission rate = 4 %
Last week,she sold $7,200 worth of stocks
<em><u>A. ) How much commission did she make last week?</u></em>
Therefore,
Thus commission made last week is $ 288
B)
Given that,
If she were to average that same commission each week
To find the commissions earned in a year, treating a year as having exactly 52 weeks
Therefore,
Thus commissions earned in a year,treating a year as having exactly 52 weeks is $ 14976

Answer:
L = 15.53 ft
Step-by-step explanation:
using diagram which is attached below
now, using Pythagoras theorem
L² = b² + (5 + x)²...............(1)
using similarity of triangle
from equation (1)
for maxima or minima
x = -5 and x = ∛190 = 5.74
on second derivative 5.74 is the value which comes out to be minimal value which is the distance between the fence and ladder
now,
L² = 241.38
L = 15.53 ft
