The width of a cuboid is half the length and one third of the height. If the length of the cuboid is 4 meters, what is the volume of three identical cuboids?

- a)96
- b)88
- c)74
- d)68
- e)62

Correct answer is option 'A'. Can you explain this answer?

NIMRAT KAUR answered • 2 days ago

Normalize all the dimensions to the width.

Let the width be X.

The length is twice the width, thus 2X.

The height is 3 times the width, thus 3X.

The volume of the cuboid is X.2X..3X = 6X^{3}.

The length is equal to 4 → 2X = 4 → X = 2 → Volume = 6 x 8 = 48.

The length is twice the width, thus 2X.

The height is 3 times the width, thus 3X.

The volume of the cuboid is X.2X..3X = 6X

The length is equal to 4 → 2X = 4 → X = 2 → Volume = 6 x 8 = 48.

The volume of two cubes will be 96.

Eating fish and other foods rich in omega-3 fatty acids could help people maintain healthy brains as they age as well as protect their hearts, new research suggests. Per this research, participants with low levels of omega-3 fatty acids in their blood had slightly smaller brains and scored lower on memory and cognitive tests than people with higher blood levels of omega-3s.

The researchers then looked at and ranked the level of omega-3 fatty acids in the participants' blood. People who scored in the bottom 25% in omega-3 fatty acid levels were compared with the rest of the study participants. Researchers found that those who had the lowest level of omega-3 fatty acid levels in their blood had lower brain gray matter volume compared with those with higher levels.

Gray matter volume is crucial to brain health. When it remains higher, brain health is being maintained. Decrease in gray matter volume indicates that brain cells are shrinking. The findings showed that consumption of baked or broiled fish on a weekly basis was positively associated with retention of gray matter volume in several areas of the brain. In fact the greater hippocampal, posterior cingulate, and orbital frontal cortex volumes obtained by optimal fish consumption led to reduced risk of contracting MCI or Alzheimer’s by almost five-fold.

The most recent U.S. dietary guidelines—released last year—recommend at least two servings of seafood a week. Some doctors and diet experts recommend that patients consume fish three times a week or take fish-oil supplements so they get enough omega-3 fatty acids to obtain health benefits.

The passage suggests the following about diet and gray matter volume

In the equation 4Y 3kX = 18, k is a constant and Y equals 42 when X equals 12. What is the approximate value of X when Y equals 36?

- a)5
- b)10
- c)15
- d)20
- e)25

Correct answer is option 'B'. Can you explain this answer?

MADHURIMA YELLA answered • 2 days ago

The best answer is B.

First, find the constant k. Plug in the numbers for X and Y, to receive 4 x 42 – 3k x 12 = 18 → k = (18 – 168)/36 = -25/6.

Now, plug in the value of Y to receive: 4 x 36 – 3kX = 18 → after a little math, X is equal to 10.08, therefore the approximate answer is 10.

Analyst 1: Many parents take their children along when they go for shopping for toys because they want to know whether the children will really enjoy playing with a toy before buying it for them. But in many cases, children ask for toys that are either out of their parents’ budgets or are somewhat unsafe for the children. Either way, it is not a good idea to take children along when shopping for toys.

Analyst 2: But since parents have the ultimate authority to decide whether to purchase a particular toy, your consideration is not valid.

Which of the following, if true, most helps to strengthen the conclusion drawn by analyst 1?

Choice overload is a term used to describe the effects of having too many options to choose from while making a decision. Under such conditions, people usually feel paralyzed and as a result are unable to make decisions for themselves. However, various studies have shown that when making decisions for others, people face what is called “reverse-choice overload”. In other words, people are enthused and more decisive while making decisions from a wide variety of available options. Clearly, people are less careful while making decisions for others and hence are not overwhelmed with the stress to make the choice.

Which of the following, if true, provides the most support for the argument?

Customers are aware that most of the faults that arise in their mobile phones are due to the excessive exposure of these phones to moisture or water. Accordingly, engineers at Talkit Inc. have developed a water-resistant phone that can stay underwater for at least 30 minutes without any resultant damage to either its hardware or software. However, since the manufacturing cost of the phone is anywhere between 25-30% more than that of an ordinary phone, trade analysts have predicted that the phone will be very expensive and as such not be able to find enough customers.

Which of the following, if true, argues in favor of the assertion that the analysts’ prediction is premature?

Oscar Mishra asked • yesterday

Although the journal Social Text was never at the forefront of publishing articles on feminism and never debated whether capitalism was the source of women’s oppression in 1970s or whether male supremacy was itself a systematic form of domination, it is not clear whether social feminist’s classification of the journal as the one run by “boy’s club” could have been completely justified till recently. There could have been many reasons that the journal’s mission statement as set out in its first prospectus in 1979 did not take notice of the burning issues feminists were then discussing. May be triumvirate of founding editors were too focused on Marxist high theory to consider gender alongside economic class as an important mode of social organization and oppression, or on the other hand they may have simply chosen on purpose to not include feminism specifically in its charter.

The recent paper by Rosa Luxemburg suggests that the first prospectus contained the seeds of its own feminist undoing. The founders demarcated fields of focus for the journal that could hardly be explored without attention to gender, sexuality, and the historical experiences of women. They were rather interested in “everyday life,” “mass culture,” and “consumer society”. Hence, the little feminist work that appears in Social Text is in the realm of cultural analysis not revolutionary praxis and is often buried in the back of the journal in “Unequal Developments,” the section that offers reviews and experimental writing.

For example, in the second edition of the journal in the section Unequal Developments, Christine Holmland performs a thorough feminist dissection of the then-current Disney film ‘The North Avenue Irregulars’, showing how this comedy about a group of church ladies who take on the local mafia superficially celebrates, but finally deflates the idea of women’s activism, and along the way reinforces gendered roles at every level of social life.

Why does the author cite Christine Holmland’s example to?

Fast food chains constantly face the problem of low employee retention, to counter which the companies offer high salaries. The companies have come up with the solution of hiring retired people who have a very low attrition rate. However, **their time taken to service an order is more and they require going through long training programs at regular intervals**. Thus, for most fast food chains the gain in employee retention does not compensate for the increase in time taken to serve each customer. Nevertheless, since **the customers continue to be more appreciative when served by retired people**, their employment is likely to become an industry-wide feature.
