Can you help me with these AP Computer Science Questions. (THIS IS DUE BY 1:30 PM today) you have to evaluate the Boolean Expres

vfiekz [6]

Answer + Explanation:

'and' -> both statements are 'True' to evaluate as 'True'.

'or' -> at least one statement is 'True' to evaluate as 'True'.

1. True (grade has the value of 82, so the statement evaluates to 'True').

2. True (Both statements are true, this expression evaluates to 'True').

3. False (Both statements are false, this expression evaluates to 'False').

4. True (the != operator means not equal. Since the 'name' variable holds the string 'Rumpelstiltskin', name != 'Rumpelstiltskin' evaluates to 'False'. The 'not' operator returns the opposite of the given Boolean expression, so this expression evaluates to 'True').

5. True (name == 'Rumpelstiltskin' evaluates to 'True', so this expression is true).

6. False (All statements evaluate to 'False').

7. True (All statements evaluate to 'True').

8. False (All statements evaluate to 'True' except for not(x == - 3) which evaluates to 'False', so the whole statement now becomes false).

9. True (grade+5 < 90 and grade >= 80 evaluates to 'True', so this whole expression becomes true).

10. True (grade > 0 and x % 2 == 1 evaluates to 'True')

Hope this helps :)

To plan a pizza party, one may want to order enough pizza for everyone. Use the slicesInPizza, slicesPerPerson, and totalGuests

zheka24 [161]

Answer:

Explanation:

The following code was written in Javascript. It asks the user to enter the values for each of the variables and saves it to them. Then it uses those values to calculate the total number of pizzas needed to feed everyone at the party. Finally, it prints out the total to the screen as an alert. Both test cases were used and the outputs can be seen in the attached images below.

var slicesPerPizza = window.prompt("How many slices per pizza?");

var slicesPerPerson = window.prompt("How many slices per person?");

var totalPersons = window.prompt("How many total people will attend?");

var pizzasNeeded = Math.round((slicesPerPerson * totalPersons) / slicesPerPizza)

alert(`You need a total of ${pizzasNeeded} pizzas.`)
