Answer:
(a)
(b)57.33831 pound/cubic feet
(c)120.1095 hp
Explanation:
We have
(a) 760 miles / hour
We know that 
And 1 hour = 60×60=3600 sec
So 
(b) 927 kg/cubic meter to mass/cubic foot
We know that 1 kg = 2.20 pound
So 921 kg = 921×2.20=2026.2 pound
We know that 1 cubic meter = 35.31 cubic feet
So 57.33831 pound / cubic feet
(c) We have to convert to hp

We know that 1 kj /sec = 1.341 hp
So 89.5 kj/sec = 89.5××1.341=120.1095 hp
Answer:
Initial radius of cylindrical specimen
ri = 15.46mm
Explanation:
Cw = [(A1 - A2)/A1] * 100% ...equation 1
Where CW = cold worked percentage gain for( 27% EL) ductile
A2 = final area of cylindrical specimen = pai * r²
Where r = final radius of cylindrical specimen
So therefore expanding equation 1 will give
A1 * Cw = (100 * A1) - (100 * A2)
Cw = 18% from attached graph
A2 = area of cylindrical specimen after cold work = pai * 14² = 615.75mm²
So therefore
18A1 = 100A1 - (100 * 615.75)
-82A1 = -61575.22
A1 = 750.92mm²
So solving for initial radius from initial area of specimen
r1 = (A1/pai)^½
r1 = (750.92/pai)^½
r1= 15.46mm

Answer:
// Program is written in C++ Programming Language
// Comments are used for explanatory purpose
#include<iostream>
using namespace std;
int main ()
{
// Variable declaration
string name;
int numQuestions;
int numCorrect;
double percentage;
//Prompt to enter student's first and last name
cout<<"Enter student's first and last name";
cin>>name; // this line accepts input for variable name
cout<<"Number of question on test"; //Prompt to enter number of questions on test
cin>> numQuestions; //This line accepts Input for Variable numQuestions
cout<<"Number of answers student got correct: "; // Prompt to enter number of correct answers
cin>>numCorrect; //Enter number of correct answers
percentage = numCorrect * 100 / numQuestions; // calculate percentage
cout<<name<<" "<<percentage<<"%"; // print
return 0;
}
Explanation:
The code above calculates the percentage of a student's score in a certain test.
The code is extracted from the Question and completed after extraction.
It's written in C++ programming language
