Answer:
420 meters
Step-by-step explanation:
The first thing we must do is understand the exercise, the first thing is that they go in opposite directions, one goes clockwise and the other goes counter-clockwise.
We can interpret that one is in the "beginning" of the track and the other is in the "middle". Let's say that the length of the track is "x"
Now, their first meeting is when Amy has traveled 120 meters, which means that how Betty is in the middle would be x/2 - 120, which she traveled. We are told that Betty traveled 180 meters after that meeting point which means, how did she start "beginning" but that beginning can also be seen as the end, that is, distance x, traveled x - 180.
We can do the following proportion:
120*180 = (x/2 -120)*(x-180)
in resolving:
x^2-420*x+43200=43200
x^2 -420*x = 0
x*(x -420)=0
x - 420 = 0
x = 420
Therefore the circular track has a length of 420 meters

Step-by-step explanation:
The business can turn a profit by cutting costs.The sum of the units sold times the price per unit is the revenue.Multiply the output level by the pricing function to get the revenue function.
How can the business save expenses?
- Total revenue is important because it gives businesses a high level understanding of the relationship between pricing and consumer demand for an additional unit of product at any given time. The total revenue formula is simply: TR = P * Q (Total Revenue = Price * Quantity Sold)
changing the personnel.
- using less expensive substitute raw materials.
- enhancing the pace of production.
- Profit for a business is the amount of income that remains after all expenses are paid.
- The profit would increase if these costs were decreased because less income would be needed to pay for manufacturing costs.
- production crew salaries and raw materials
- The entire income generated from the sale of x units of the product is represented by the revenue function R(x).
- The total profit made from producing and selling the x units of the product is represented by the profit function, P(x).
- Price of goods or services divided by the quantity or number of clients equals revenue.
- For instance, if a business sells 10 computers for $50,000 each, it may figure out its gross income using the following formula:Gross revenue = ₹50,000 × 10 = ₹500,000.
