This problem is actually under the subject of Mathematics, particularly, Algebra. For work problems, you can use a convenient technique of dimensional analysis. This is done by multiplying units of measurement, then cancelling out like terms in order to come up with the units of the final answer. For this problem, the total amount of liters is 2,100. So, the equation would be
Volume of Kelly's family + Volume of Stewart's family = 2,100
However, we are only given the rates for each family in liters per hour. To come up with the final answer with a unit of measurement in Liters, we must multiple the rate of L/hour with the individual time. Let x be the time Kelly's sprinkler was used, and y for Stewart's family.
(20 L/h)(x hours) + (40 L/h)(y hours) = 2,100
This is the first equation. The second equation is the total time.
x + y = 65 hours
Rearranging the equation, y = 65 - x. Let's substitute this to the first equation.
20x + 40(65-x) = 2,100
Solving for x, then substituting it to the second equation to obtain y,
x = 25 hours
25 + y = 65
y = 40 hours.
Thus, Kelly's sprinkler was used for 25 hours, while Stewart's sprinkler was used for 40 hours.
Answer:
a. will you receive a margin call?
No you wouldn't. You borrowed $20,000 on the margin which means that you invested $20,000 of your own money. You purchased 1,000 stocks (= $40,000 / $40) of ixnay at $40, and now the stock price is $35. This means that you lost $5,000, and you percentage on the margin = $15,000 / $35,000 = 43%. Since the maintenance margin is 35%, you are still in.
b. how low can the price of ixnay shares fall before you receive a margin call?
we can use the following formula = (1,000price - $20,000)/1,000price = 35%
350price = 1,000price - $20,000
$20,000 = 1,000price - 350price = 650price
price = $20,000/650 = $30.769 ≈ $30.77 or lower
Well yes but not just that when u slow down u mite get a ticket so yea.
Answer:
(d)cannot tell without more information.
Explanation:
Autarkic economy is a self reliant economy, consuming entirely from its own production.
An autarkic economy maximises its utility when : Its PPF & Social Indifference Curve are tangent to each other.
- PPF is sort of a budget constraint to economy, because it denotes maximum production potential with given resources & technology.
- Social Indifference Curve is the curve denoting product combinations yielding same level of social satisfaction.
Their tangency gives utility maximising point with the available resources & technology.
Other options are inapt because: Production on PPF is a necessary but not sufficient condition for social utility maximisation (tangency also needed). Production under PPF reflects under utilisation of resources, cant be utility maximising. Production above PPF is unattainable.
