A project requires transporting 13,000 cy of sand using (12) - cy dump trucks. A front-end loaded will load trucks at a rate pf 95 cy / hr. The trucks will transport the sand (7) miles at an average haul speed of 30 mi / hr, return speed of 40 mi / hr, and dump time of (3) minutes. Assume a (45) min effective hour for all equipment. (a) Calculate the number of trucks required to balance the production rate of the loader and (b) estimate the time to transport the sand based on the calculated number of trucks.

this is true

i looked it up

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
