Help 2 what the answer for this?
Answer: a single compound
Explanation: I know it
Answer:
142.82 g
Explanation:
The following data were obtained from the question:
Volume of water = 12 mL
Volume of water + gold = 19.4 mL
Density of gol= 19.3 g/cm³
Mass of gold =.?
Next, we shall determine the volume of the gold. This can be obtained as follow:
Volume of water = 12 mL
Volume of water + gold = 19.4 mL
Volume of gold =.?
Volume of gold = (Volume of water + gold) – (Volume of water)
Volume of gold = 19.4 – 12
Volume of gold = 7.4 mL
Finally, we shall determine the mass of the gold as follow:
Note: 1 mL is equivalent to 1 cm³
Volume of gold = 7.4 mL
Density of gol= 19.3 g/cm³ = 19.3 g/mL
Mass of gold =?
Density = mass /volume
19.3 = mass of gold /7.4
Cross multiply
Mass of gold = 19.3 × 7.4
Mass of gold = 142.82 g
Therefore, the mass of the gold pebble is 142.82 g
The statement was false as it mentioned, the profit-maximizing rule leaves room for cases where it is both possible and reasonable for a firm to operate at a loss over the long run
What is profit-maximizing rule ?
According to the Profit Maximization Rule, if a corporation want to maximise its profits, it must select the level of output where Marginal Cost (MC) equals Marginal Revenue (MR) and the Marginal Cost curve is increasing. To put it another way, it must generate at a level where MC = MR.
The profit maximization rule formula is as follows:
MC = MR
The marginal cost is the cost increase caused by manufacturing one extra unit of an item.
The difference in total revenue as a result of altering the rate of sales by one unit is referred to as marginal revenue. The slope of Total Revenue is also known as Marginal Revenue.
Total Revenue - Total Costs = Profit
Profit maximisation happens when there is a considerable gap or disparity between total revenue and total cost.
so the given statement the profit-maximizing rule leaves room for cases where it is both possible and reasonable for a firm to operate at a loss over the long run. was a false statement.
