Answer:
All real numbers Interval Notation: (-∞,∞)
Step-by-step explanation:
Any value of n makes the inequality true.
Hope this helps.
He will mix some 20% solution and some 70% solution to make 60% solution.
Let x = number of liters of 20% solution.
Let y = number of liters of 70% solution.
He wants to make 50 liters of 60% solution, so
x + y = 50 First Equation
The amount of acid in x amount of 20% solution is 20% of x, or 0.2x
The amount of acid in y amount of 70% solution is 70% of y, or 0.7y
The amount of acid in 50 liters of 60% solution is 60% of 50 liters, or 0.6 * 50 = 30
Now we add the amounts of acid.
0.2x + 0.7y = 30 Second Equation
x + y = 50
0.2x + 0.7y = 30
-0.2x - 0.2y = -10
0.2x + 0.7y = 30
------------------------
0.5y = 20
y = 40
x + y = 50
x + 40 = 50
x = 10
Answer: He needs 10 liters of 20% solution and 40 liters of 70% solution.
Answer:
The worth of the company in 2000 is $56,000.
Step-by-step explanation:
The growth rate of the company is:

To determine the worth of the company in 2000, first compute the change in the net worth during the period 1990 (<em>t</em> = 0) to 2000 (<em>t</em> = 10) as follows:

The increase in the company's net worth from 1990 to 2000 is $16,000.
If the company's worth was $40,000 in 1990 then the worth of the company in 2000 is:
Worth in 2000 = Worth in 1990 + Net increase in company's worth

Thus, the worth of the company in 2000 is $56,000.
