Answer:

Steve can mow the lawn in 240 minutes

Explanation:

It is given Hillary works three times as fast as Steve

When both work together the work is completed in 60 minutes

Let Steve can do 1 work in 1 minute

So Hillary can do 3 work in 1 minute

So work done by both in 1 minute = 1+3 = 4

As they can complete the work in 60 minutes

So total work = 4×60 = 240 work

As Steve can do 1 work in a minute

So time taken by Steve to complete the work =\frac{240}{1}=240minutes

Answer:

Steve will take 240 minutes or 4 hours.

Explanation:

Steve and Hillary can mow a lawn in 60 minutes by working together. However, Hillary works three times faster than Steve.

Let's assume Steve takes takes x minutes to mow alone.

This implies that Hillary can mow alone in x/3 minutes.

In a minute, Steve can mow 1/x of the lawn, so this means Hillary can mow 3/x of the lawn.

In a minute together then can mow,

= \frac{1}{x} + \frac{3}{x}

= \frac{4}{x}

In 60 minutes they can mow

= \frac{4}{x} \times 60

= \frac{240}{x}

This means that it takes 4 hours for Steve to mow the lawn alone.

A construction company entered into a fixed-price contract to build an office building for $32 million. Construction costs incur
Delicious77 [7]

Answer:

company gained a gross profit of $2 million

Explanation:

Data provided in the question;

Contract price to build an office = $32 million

Construction costs incurred during the first year = $9 million

Estimated costs to complete at the end of the year = $21 million

Therefore,

Total cost incurred to complete the construction of the office at the end of the first  year

=  Construction costs incurred during the first year + Estimated costs to complete at the end of the year

= $9 million + $21 million

= $30 million

Thus,

The revenue generated by the company = Contract price - cost incurred

= $32 million - $30 million

= $2 million

since the revenue is positive, hence the company gained a gross profit of $2 million

Which of the following analytical techniques is designed to output the best decision?
navik [9.2K]

Answer:

Prescriptive analytics      

Explanation:

Prescriptive Analytics refers to the data analytics field that specializes on determining the best approach in a situation, based on the data accessible. It is linked towards both descriptive analytics as well as predictive analytics yet highlights valuable insights rather than data analysis.  

Prescriptive analytics collects information with its systems from either a range of descriptive or predictive databases and relates it to the choice-making process. It involves mixing existing conditions with alternative actions to evaluate how well the outcome would be influenced by each.

It can also assess the effects of judgment, based on various potential future situations. The discipline draws inspiration from applied mathematics, using a number of statistical techniques to construct and re-create potential judgment trends that could have different effects on an entity.

Aliun [14]

Answer:

See explanation section

Explanation:

(a) December 1     Cash             Debit    $18,000

                        Unearned revenue      Credit    $18,000

<em>Note: The company received the money in advance for a contract to do during December to April. Therefore, they received cash while a liability increased due to receiving advance money.</em>

(b) December 31   Unearned revenue     Debit    $3,600

                            Service revenue           Credit    $3,600

<em>Note: As the company started performing, after the completion of 1st month, i.e., December 1 to December 31, the advance money started expiring because of providing services. Moreover, as the service is performed evenly for 5 months, the 1st month's revenue = $(18,000/5) = $3,600.</em>

Choose one of the scenarios below and write a three-paragraph essay describing its effect on prices for food, housing, and oil.
Ray Of Light [21]
<span>The issue isn't black and white, a true answer is closer to the middle ground but to play devil's advocate I personally believe investors have a net positive effect on companies they keyword: invest in. Investments naturally leads to expansion and growth, that's always at least a main goal of anyone profitable company. It produces more jobs, but it can have the negative effect of curbing jobs in the name of cutting costs. A lasting problem is an overreliance in investment when companies don't have enough liquidity to continue running and is forced to sell assets valuable to the business in times of panics and reduced investment. Overall investors are in large part a reason for the success of modern corporations.</span>
