Answer:
The rate of tax is 0.9% of the actual business amount.
Step-by-step explanation:
Given that:
Tax amount = $1035
Business value = $115,000
So, for finding the rate, we will have to divide the tax amount by business value and multiply it by 100 as follows:
Rate = 1035/115,000 * 100
By simplifying we get:
Rate = 0.009 *100
Rate = 0.9 %
This means that the tax rate is 0.9% of the original amount.

Answer:
Therefore the concentration of salt in the incoming brine is 1.73 g/L.
Step-by-step explanation:
Here the amount of incoming and outgoing of water are equal. Then the amount of water in the tank remain same = 10 liters.
Let the concentration of salt be a gram/L
Let the amount salt in the tank at any time t be Q(t).

Incoming rate = (a g/L)×(1 L/min)
=a g/min
The concentration of salt in the tank at any time t is =
g/L
Outgoing rate =



Integrating both sides

[ where c arbitrary constant]
Initial condition when t= 20 , Q(t)= 15 gram


Therefore ,
.......(1)
In the starting time t=0 and Q(t)=0
Putting t=0 and Q(t)=0 in equation (1) we get









Therefore the concentration of salt in the incoming brine is 1.73 g/L
For this case we have the following expression:

By definition, a coefficient is the term that accompanies one or more variables.
For example:

The coefficient of the linear term is 3.
So, in the given expression we have to:
-4 is the term that accompanies the variables xy.
Answer:
-4
