I believe they are icons.
Answer:
#include<bits/stdc++.h>
using namespace std;
int sumOfinteger(int );
// Returns sum of all digits in numbers from 1 to n
int sumOfintegersFrom1ToN(int n) {
int result = 0; // initialize result
// One by one compute sum of digits in every number from
// 1 to n
for (int x = 1; x <= n; x++)
result += sumOfinteger(x);
return result;
}
// A utility function to compute sum of digits in a
// given number x
int sumOfinteger(int x) {
int sum = 0;
while (x != 0) {
sum += x %10;
x = x /10; }
return sum; }
// Driver Program
int main() {
int n ;
cout<<"enter a number between 1 and n : ";
cin>>n;
cout << "Sum of digits in numbers from 1 to " << n << " is " << sumOfDigitsFrom1ToN(n);
return 0; }
The answer is C: Does the paint being used contain any aluminum?
Paint booth filters will be considered hazardous waste if hazardous compounds are present. The easiest way to determine if a paint booth filter is hazardous is to review the data sheets for the paint and the solvents you use. If the paint or solvents contains heavy metals like lead, aluminum, cadmium, or chromium, the spent filters would be considered a hazardous waste.
