Answer: 45%
Step-by-step explanation:
Converting the word problem into words, we have:
18= x/100*40
Solving for it, we get that x=45.
Answer: C
Step-by-step explanation:
When there is division inside a set of parentheses, you can distribute the power to each term. When you take a power to another power, you multiply the powers.
-5 x -4 = 20
-2 x -4 = 8
So your answer is:

Answer:
The steady state solution of the system is calculated in the diagram below:
The linear function that describes the total cost of a tiny house, based on the number of square feet A is given by:
C = 175A + 1000.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem:
- The house has a fixed cost of $1,000 for the factory equipment, hence the y-intercept is of b = 1000.
- The variable cost is of $175 per square foot, hence the slope is of a = 175.
Then, the equation is given as follows:
C = 175A + 1000.
