Explanation:
The italicized are given from the question [unchanged]
import math
paint_colors = {'red': 35,'blue': 25,'green': 23}
wall_height = int(input('Enter wall height (feet):\n'))
This gets input for width
wall_width = int(input('Enter wall width (feet):\n'))
Calculate the wall area
area = wall_height*wall_width
Print the calculated wall area
print('Wall area:',area,'square feet')
Calculate the amount of paint needed
paint_needed = area/350.0
Print the amount of paint needed to 2 decimal places
print('Paint needed: {:.2f} gallons'.format(paint_needed))
Print the amount of can needed to nearest integer
print('Cans needed:',round(paint_needed),'can(s)')
Prompt user for color of paint [here, we assume the user input is correct]
color = input("Choose a color to paint the wall: ")
Prints the corresponding amount for the color
print("Cost of purchasing", color, "paint: $",paint_colors[color])

Write a program named prices.c that repeatedly asks users to enter the price of an item until they enter zero. Prices less than zero will be ignored. The program will then print the number of items purchased, the subtotal of the prices, the sales tax charged (at a rate of 7.5%), and the grand total.
Answer:
Explanation:
The following is written in Java. It creates a while loop that requests price from the user and goes adjusting the quantity and subtotal as more prices are added. If 0 is entered it breaks the loop and outputs the quantity, subtotal, tax, and grand total to the user.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int quantity = 0;
double subtotal = 0;
double tax, grandTotal;
while (true) {
System.out.println("Enter a price: ");
double price = in.nextDouble();
if (price == 0) {
break;
} else if (price > 0) {
quantity += 1;
subtotal += price;
}
}
tax = subtotal * 0.075;
grandTotal = subtotal + tax;
System.out.println("Quantity: $" + quantity);
System.out.println("Subtotal: $" + subtotal);
System.out.println("Tax: $" + tax);
System.out.println("GrandTotal: $" + grandTotal);

Answer:
H-Br bond is polar, hydrogen is partly positive and bromine is partly negative
H-Cl bond is polar, hydrogen is partly positive and bromine is partly negative
O-H bond in water is polar, hydrogen is partly positive and oxygen is partly negative
C-O bond in CH40 is polar, carbon is partly positive and oxygen is partly negative
Explanation:
A molecule possess a dipole moment when there is a large difference in electro negativity between two bonding atoms in the molecule.
The presence of dipole moments introduces polarity to the molecule. In all the molecules listed in the answer, the shared electron pair of the bond is closer to the more electronegative atom causing it to be partially negative while the less electronegative atom in the bond is partially positive.
Write a function called reverse Return that is almost the same job as reverse, but instead of printing the letters straight to the screen, it returns a String in which the letters have been reversed. The function call would look like:
Answer:
The function in Python is as follows:
def reverse(inputstr):
outputstr = ""
for i in inputstr:
outputstr = i + outputstr
return outputstr
Explanation:
This defines the function
def reverse(inputstr):
This initializes the output string
outputstr = ""
This iterates through the input string
for i in inputstr:
This generates the output string by reversing the input string
outputstr = i + outputstr
This returns the reversed string
return outputstr

If the code for JAVA is LCXC, what is the code for BASIC?
Answer:
DCUKE
Explanation:
Given that,
Code for JAVA = LCXC
To find,
Code for BASIC = ?
As we observe the pattern,
In "JAVA", every letter moved two-letter forward in their alphabetical order or we can say that every third alphabet of the given letter is used to make the code:
J + 2 = L
A + 2 = C
V + 2 = X
A + 2 = C
Similarly,
B + 2 = D
A + 2 = C
S + 2 = U
I + 2 = K
C + 2 = E
Thus, DCUKE is the code for BASIC.
The code for BASIC given the code for JAVA is; DCUKE
We are given the code for JAVA as LCXC
From that code for "JAVA", we see that every letter is moved forward two letters in their alphabetical order. This means
J = L because L comes after J and KA = C because C comes after A and BV = X because X comes after V and UA = C because C comes after A and BSimilarly for BASIC;
B = D because D comes after B and CA = C because C comes after A and BS = U because U comes after S and TI = K because K comes after I and JC = E because E comes after C and DThus, finally the code for BASIC is DCUKE
