The building of a hacker rank is one that cost a lot of money and as such the minimum cost is 4.
What is the minimum cost?
The minimum cost is the lowest cost that is needed to complete a building. It depends on:
- The cost of each type of house to be built (e.g. cost of a wood house, cost of a brick house, etc.)
- The number of the type of house to be built e.g. 2 03 3 or even more.
When one is given input such as : [[1,2,3],[1,2,3],[3,3,1]] (the values in column stands for the cost of materials)
The output : 4
So you have to:
Select material-1 of cost 1 in first house(row)
Select material-2 of cost 2 in second house(row)
Select material-3 of cost 1 in third house (row)
total = 1+2+1 -> 4

The height of the ball at time t is given as h = -16t² + 14t + 6 while the height of the receiver hand at time t is given as h = -16t² + 10t + 8
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
A quarterback throws a football toward a receiver from a height of 6 ft. The initial vertical velocity of the ball is 14 ft/s. At the same time that the ball is thrown, the receiver raises his hands to a height of 8 ft and jumps up with an initial vertical velocity of 10 ft/s.
The height of the ball at time t is given as h = -16t² + 14t + 6 while the height of the receiver hand at time t is given as h = -16t² + 10t + 8

The forth wall acts as a barrier between the fictional world and the real world. I would believe the answer to this is C, the characters speak directly to and interact with the audience.
The number of electrons passes through 20 ohms resistor in 10 minutes is 5.625e+21.
<h3>What is a resistor?</h3>
In an electronic circuit, a resistor is an electrical component that limits or regulates the flow of electrical current.
Given, the resistance is 20 ohms.
The potential difference is 30 volts
Time is 10 minute
By the formula of current

The charge flowing through the resistor is 1.5 C/s
1 electron charge is 1.6e+19
Now, the number of electrons passing through a 20 ohms resistor is

In 10 minutes

Thus, the number of electrons passes through 20 ohms resistor in 10 minutes is 5.625e+21.
