Write the definition of a function named alternator that receives no parameters and returns true the first time it is invoked, r
Nataly [62]

Answer:

The solution code is written in C++

  1. bool STATUS = true;
  2. bool alternator ()
  3. {
  4.    if(STATUS){
  5.        STATUS = false;
  6.        return true;
  7.    }else{
  8.        STATUS = true;
  9.        return false;
  10.    }
  11. }

Explanation:

We need a global variable to track the status of true or false (Line 1).

Next, create the function alternator (Line 2) and then check if current status is true, set the status to false but return the previous status boolean value (Line 5-6). At the first time of function invocation, it will return true.

The else block will set the STATUS to true and return the false (Line 7-9).

A painting company has determined that for every 115 square feet of wall space, one gallon of paint and eight hours of labor wil
Reptile [31]

Answer:

Follows are the code to the given question:

Wallsize = int(input("Enter the size of wall space for painting(in sq ft): "))#defining variable Wallsize for input value  

rate = int(input("Enter the price of the paint(per gallon): $"))#defining variable rate for input value

per_Gallon = Wallsize/115#defining a variable per_Gallon that calculate its value

print("Number of Gallons of paint: ",per_Gallon)#print value with message

total_Hours = per_Gallon * 8#defining a variable total_Hours that calculate its value

print("Hours of labor required: ",total_Hours)#print value with message

paint_Cost = rate * per_Gallon#defining a variable paint_Cost that calculate its value

print("Cost of the paint: $",paint_Cost)#print value with message

labor_Charge = total_Hours * 20#defining a variable labor_Charge that calculate its value

print("Labor charges: $",labor_Charge)#print value with message

total_Cost = paint_Cost + labor_Charge#defining a variable total_Cost that calculate its value

print("Total cost of paint job: $",total_Cost)#print value with message

Output:

Enter the size of wall space for painting(in sq ft): 800

Enter the price of the paint(per gallon): $33

Number of Gallons of paint:  6.956521739130435

Hours of labor required:  55.65217391304348

Cost of the paint: $ 229.56521739130434

Labor charges: $ 1113.0434782608695

Total cost of paint job: $ 1342.6086956521738

Explanation:

Please find the complete question in the attached file.

In this code, the "Wallsize and rate" two variable is defined that is used for input the value from the user-end, after input the value multiple variables"

per_Gallon, total_Hours,paint_Cost, labor_Charge, and total_Cost" is declared, in which it calculates its respective value and prints the value with the message value.

A circuit is supplied with 30 VDC and contains three resistors connected in series. The value or R1 is 80 , the value of R2 is 1
sukhopar [10]
The answer is 5.68 Volts.

So givens are electric supply of 30 VDC and the values of 3 resistors. 

Given:
E= 30 VDC
R1 = 80 Ohms
R2 = 1000 Ohms
R3= 42000 Ohms

And what we are looking for is the voltage on the second resistor.
First we have to get the current of the circuit.

I = E/(R1+R2+R3)
I = 30 / (80+1000+4200)
I = 30 / (5280)
I = 0.00568 A

Then get the voltage V = I x R

V = 0.00568 x 1000
V = 5.68 V
