ABC Company is unloading coal from a barge on the Mississippi River. The barge contains 1,760 tons of coal. The coal is shoveled

out of the barge with a material handling machine into dump trucks. Each truck takes 4 minutes to load, 4 minutes to travel to the dump site, 4 minutes to dump, and 4 minutes to return. Each dump truck holds 22 tons of coal. Assuming no delays, how quickly can the barge be unloaded and what is the optimal number of dump trucks to be used?

Answer:

The answer is: 5 hours 20 minutes; 4 Trucks

Explanation:

Each truck has a 16 minute window to pick up and dump the coal. This process can be observed as an assembly line where each stage of production is the stages of coal transport. When Truck A is travelling to the dump site, Truck B can be loading the coal. When Truck B is travelling to the dump site and Truck A is dumping the coal, Truck C would be loading the coal. When Truck A is travelling to the loading area, Truck B dumping the coal and Truck C travelling to the dump site, Truck D would be loading the coal. Once Truck A gets to the loading area, Truck D would be on its way to the dump site and so on. In each 16 minute window 88 tons of coal (22 tons * 4) is picked up and dumped, that is, 22 tons every 4 minutes. Given that there are 1, 760 tons of coal, the total time taken to dump all the coal is equal to 320 minutes:

88 tons = 16 minutes (22 tons dumped every 4 minutes)

1, 760 tons = (1760 tons * 16)/88 tons = 320 minutes

320 minutes/ 60 minutes = 5 hours 20 minutes

With a framework in place, controls and risk become more measurable. The ability to measure the enterprise against a set of stan
weeeeeb [17]

Answer:

True

Explanation:

When a company as a framework to measure risk against, it can properly assess risk in different periods of time, depending of the risk score obtained within the framework.

This helps regulators because they can access an accurate primary information from the company itself (later on, they should probably compare that information against their own standards in order to prevent bias), and it also helps the company because it can see where it stands in terms of risk, which reduces uncertainty.

A client has been given atropine to cause mydriasis and cycloplegia. What is the expected outcome for this client?
Nady [450]

Answer:

dilation of the pupil and loss of accommodation

Explanation:

Mydriasis is the dilation of the pupil of the eye. The dilation causes vision to be blurry.

Cycloplegia on the other hand is the loss of accommodation of the pupil and it is caused by the paralysis of the cilliary muscle of the eye. This paralysis causes the eyes to lose its ability to focus on things nearby.

Looking at this two conditions from the administration of atropine, the expected outcome of the client is blurry vision and inability to focus or see things close by(farsightedness).

I hope this helps.

zloy xaker [14]

Answer:

c. Sales budget, budgeted income statement, budgeted balance sheet

Explanation:

First, we calculate the sales for the period. It would also calculatethe cash proceeds from sales, which will be useful for the balance sheet.

With that, we can plug sales revenue into the income statement and calcualte the net income.

And with the income statement, we can solve for retained earnings and build up the balance sheet. Among other data

Doing it in any other order, we are going to leave blanks and need to do the next one to fill them. In the proposed orde,r we do not need information from the subsequent budget to complete the previous one, which is good.

You manage a risky portfolio with an expected rate of return of 18% and a standard deviation of 30%. The T-bill rate is 6%. Your
Roman55 [17]

Answer:

Explanation:

Expected return of the portfolio is weighted average of the return of the components.

E(R) = w1 * R1 + w2 * R2

E(R) = 65% * 18% + 35% * 6%

E(R) = 11.70% + 2.10%

Expected Return, E(R) = 13.80%

Standard deviation of portfolio is mathematically represented as:

\sigma =\sqrt{w_1^2\sigma _1^2+w_2^2\sigma _2^2+2w_1w_2p_{1,2}\sigma_1\sigma_2}

where

w1 = the proportion of the portfolio invested in Asset 1

w2 = the proportion of the portfolio invested in Asset 2

σ1 = Asset 1 standard deviation of return

σ2 = Asset 2 standard deviation of return

For risk free money market fund, standard deviation = 0 and its correlation with risky portfolio = 0

\sigma  =\sqrt{ (0.65 * 0.30)^2 + (0.35 * 0)^2 + (2 * 0.65 * 0.30*0.35 *0*0)} \\\\= \sqrt{0.038025 +0+0} \\\\ = 0.195

Standard deviation = 19.50%
