Answer:

Efficient when the marginal benefits of project = marginal costs of project.

Explanation:

Majority Decision Rule:

Majority decision rule is based on the notion of equality. An alternative is selected which has majority of votes. The simple majority decision rule may generate efficient results if the marginal benefits of a project are equal or greater than the marginal costs of the project.

Explain why the failure of a garden hose occurred near its end and why the tear occurred along its length. Use numerical values

Nataliya [291]

Answer:

Most hydraulic systems develops pressure surges that may surpass settings valve. by exposing the hose surge to pressure above the maximum operating pressure will shorten the hose life.

Explanation:

Solution

Almost all hydraulic systems creates pressure surges that may exceed relief valve settings. exposing the hose surge to pressure above the maximum operating pressure shortens the hose life.

In systems where pressure peaks are severe, select or pick a hose with higher maximum operating pressure or choose a spiral reinforced hose specifically designed for severe pulsing applications.

Generally, hoses are designed or created to accommodate pressure surges and have operating pressures that is equal to 25% of the hose minimum pressure burst.

Let’s define a new language called dog-ish. A word is in the lan- guage dog-ish if the word contains the letters ’d’, ’o’, ’g’ a

attashe74 [19]

Answer and Explanation:

// code

class Main {

public static void main(String[] args) {

* your code

System.out.println(inDogish("aplderogad"));

System.out.println(inXish("aplderogad", "dog"));

}

// returns true if the word is in dog-ish

// returns false if word is not in dog-ish

public static boolean inDogish(String word) {

// first find d

if (dogishHelper(word, 'd')) {

// first find string after d

String temp = word.substring(word.indexOf("d"));

// find o

if (dogishHelper(temp, 'o')) {

// find string after o

temp = temp.substring(temp.indexOf("o"));

// find g

if (dogishHelper(temp, 'g'))

return true;

}

The output is attached below

}

return false;

}

// necessary to implement inDogish recursively

public static boolean dogishHelper(String word, char letter) {

// end of string

if (word.length() == 0)

return false;

// letter found

if (word.charAt(0) == letter)

return true;

// search in next index

return dogishHelper(word.substring(1), letter);

}

// a generalized version of the inDogish method

public static boolean inXish(String word, String x) {

if (x.length() == 0)

return true;

if (word.length() == 0)

return false;

if (word.charAt(0) == x.charAt(0))

return inXish(word.substring(1), x.substring(1));

return inXish(word.substring(1), x.substring(0));

}
