You will make 4 sales if you are making a sale between 3 and five because 4 is whats in between 3 and 5. If your are to compute you will make a sale of average 4 because the average of 3 and 4 is 5. Computed as 3+5/2=4.
        
             
        
        
        
Answer:
0 to StartFraction pi Over 2
Step-by-step explanation:
we know that
If the arc on a circle measures 85 degrees, then the measure of the central angle is also 85 degrees too
so
The central angle in degrees is within the range 
Convert to radians
Remember that

therefore
the range in radians is

The best way to put them into a number line is to make sure that they've all got the same denominator, which in this case, will be 24, as this is the lowest common multiple of 3,4 and 8. You will then need to multiply these fractions accordingly. The first one (1/4) will need to be multiplied by 6 to get a denominator of 24, so this will then give you a result of 6/24. The second one (2/3), will need to be multiplied by 8, which will then give you a result of 16/24. The third one (3/4)will also need to be multiplied by 6, giving you 18/24. The final one (6/8) will need to be multiplied by 3, giving you 18/24. You will then need to put these in order, which will be- 1/4, 2/3, 3/4, and 6/8.
The alternative method is to turn these into decimals- 1/4 is equivalent to 25%, which is equal to 0.25. 2/3 is equivalent to 66.66%, which is equivalent to 0.66. 3/4 is equivalent to 75%, which is equal to 0.75. 6/8 is also equivalent to 75%, which is equal to 0.75, you can then easily line them up this way.
Hope this has been able to help you
        
             
        
        
        
Answer:
The differential equation for the amount of salt A(t) in the tank at a time  t > 0 is  .
.
Step-by-step explanation:
We are given that a large mixing tank initially holds 500 gallons of water in which 50 pounds of salt have been dissolved. Another brine solution is pumped into the tank at a rate of 3 gal/min, and when the solution is well stirred, it is then pumped out at a slower rate of 2 gal/min. 
The concentration of the solution entering is 4 lb/gal.
Firstly, as we know that the rate of change in the amount of salt with respect to time is given by;
 
 
where,  = concentration of salt in the inflow
 = concentration of salt in the inflow  input rate of brine solution
 input rate of brine solution
and  = concentration of salt in the outflow
 = concentration of salt in the outflow  outflow rate of brine solution
 outflow rate of brine solution
So,  = 4 lb/gal
 = 4 lb/gal  3 gal/min = 12 lb/gal
 3 gal/min = 12 lb/gal
Now, the rate of accumulation = Rate of input of solution - Rate of output of solution
                                                 = 3 gal/min - 2 gal/min
                                                 = 1 gal/min.
It is stated that a large mixing tank initially holds 500 gallons of water, so after t minutes it will hold (500 + t) gallons in the tank.
So,  = concentration of salt in the outflow
 = concentration of salt in the outflow  outflow rate of brine solution
 outflow rate of brine solution
              =  =
 = 
Now, the differential equation for the amount of salt A(t) in the tank at a time  t > 0 is given by;
=
