Which expression represents the phrase " the difference of 18 and 12"?

Answer:

166,000

Step-by-step explanation:

1x166,000=166,000

Answer:

The algorithm is given below.

#include <iostream>

#include <vector>

#include <utility>

#include <algorithm>

using namespace std;

const int MAX = 1e4 + 5;

int id[MAX], nodes, edges;

pair <long long, pair<int, int> > p[MAX];

void initialize()

{

   for(int i = 0;i < MAX;++i)

       id[i] = i;

}

int root(int x)

{

   while(id[x] != x)

   {

       id[x] = id[id[x]];

       x = id[x];

   }

   return x;

}

void union1(int x, int y)

{

   int p = root(x);

   int q = root(y);

   id[p] = id[q];

}

long long kruskal(pair<long long, pair<int, int> > p[])

{

   int x, y;

   long long cost, minimumCost = 0;

   for(int i = 0;i < edges;++i)

   {

       // Selecting edges one by one in increasing order from the beginning

       x = p[i].second.first;

       y = p[i].second.second;

       cost = p[i].first;

       // Check if the selected edge is creating a cycle or not

       if(root(x) != root(y))

       {

           minimumCost += cost;

           union1(x, y);

       }    

   }

   return minimumCost;

}

int main()

{

   int x, y;

   long long weight, cost, minimumCost;

   initialize();

   cin >> nodes >> edges;

   for(int i = 0;i < edges;++i)

   {

       cin >> x >> y >> weight;

       p[i] = make_pair(weight, make_pair(x, y));

   }

   // Sort the edges in the ascending order

   sort(p, p + edges);

   minimumCost = kruskal(p);

   cout << minimumCost << endl;

   return 0;

}

Q2 :) hope this helps!

Step-by-step explanation:

Answer:

5.00

Step-by-step explanation:

20%=0.20

To find 20% of 25, you will multiply 0.20 and 25

0.20x25=5.00

The amount is a $5 tip.

I hope I'm right and I hope this helps:)

Answer:

B. a = rⁿ

C. a¹/ⁿ = r

Step-by-step explanation:

ⁿ√a = r

The above expression can be simplified as follow:

1. ⁿ√a = r

Recall:

ⁿ√a = a¹/ⁿ

Therefore,

a¹/ⁿ = r

2. ⁿ√a = r

Take the n square of both side

(ⁿ√a)ⁿ = rⁿ

(a¹/ⁿ)ⁿ = rⁿ

a = rⁿ

The number of problems solved per hour is proportional to the number of team members solving the problems.

• The number of team members needed to solve 39 problems in one hour are 6 team members.

Reasons:

The time it takes 2 members to solve 13 problems = 1 hour

The rate at which each team member solve problems = The same rate

Required:

The number of team membersto solve 39 problems in 1 hour

Solution:

The time it takes 2 members to solve 13 problems = 1 hour

Let x represent the number of team members needed to solve 39 problems in 1 hour.

Using a proportional relationship approach, given that the duration is the same, we have;

Which gives;

2 × 3 = x × 1

6 = x

x = 6

• The number of team members needed to solve 39 problems in 1 hour is x = 6 team members.

Answer:

6 team members

Step-by-step explanation:

We know that 2 team members can solve 13 problems in an hour. So, all you have to do is find what 39÷13 is, and multiply that by 2.

39÷13= 3

3*2= 6

And we have our answer!

I hope this helps! If it did, it would mean a lot to me if you could mark me brainliest :D

Have a nice day!
