3) a scraper with a 275 hp. diesel engine will be used to excavate and haul earth for a highway project. an evaluation of the job-site conditions indicates the scraper will operate 40 min./hr. for this project it is anticipated that the total cycle time will be 20 min. for a round trip. previous job records show the scraper operated at full power for the 1.5 min. required to fill the bowl of the scraper and at 80% of the rated hp. for the balance of the cycle time. calculate the gallons per hour for fuel consumption of the scraper.

explanation:

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
