(True/False): A hexadecimal literal may be written as 0x3A.

9: perfect.cpp) A number is called perfect if the sum of its divisors is equal to the original number. A number is called deficient if the sum of its divisors is less than the original number. A number is called abundant if the sum of its divisors is more than the original number. Write a program that answers the following questions: What numbers below 5000 are perfect? What odd numbers below 5000 are abundant? What are the relative proportions of deficient, abundant, and perfect numbers? 5000 should be in a global constant.

5. (Algebra: solve 2 X 2 linear equations) You can use Cramer's rule to solve the following 2 X 2 system of linear equation: ax + by = e cx + dy = f ● x = ed - bf bc ad y = af - ec ad bc - Write a program that prompts the user to enter a, b, c, d, e, and f and display the result. If ad- bc is 0, report that The equation has no solution. Enter a, b, c, d, e, f: 9.0, 4.0, 3.0, -5.0, -6.0, -21.0 Enter x is -2.0 and y is 3.0 Enter a, b, c, d, e, f: 1.0, 2.0, 2.0, 4.0, 4.0, 5.0 Enter The equation has no solution

1)-Write a Java program that reads values for three sides of a triangle. The sides will form atriangle if the values are greater than zero and the sum of any two sides is greater than thethird side. The program should classify the triangle as either isosceles, scalene, equilateral, orboth right-angled and scalene according to the following rules:• An equilateral triangle has all sides equal• An isosceles triangle has only two sides equal• A scalene triangle has no sides equal• In a right-angled triangle, the square of the longest side must be equal to the sumof the squares of the other two sides. (i.e., if c is the longest side among sides a, band c of a right-angled triangle then c2 = a2 + b2). Here are some specific requirements:• Include a boolean method named checkTriangle, which accepts threedouble values as arguments and returns true if they form a triangle (otherwisereturns false)• Include a value returning method named getLongest, which accepts threedouble values as arguments…

Background: Game Rules The rules to the (dice) game of Pig:   You will need 2 dice.   To Play: a.  The players each take turns rolling two die. b.  A player scores the sum of the two dice thrown (unless the roll contains a 1): If a single number 1 is thrown on either die, the score for that whole turn is lost (referred to as “Pigged Out”). A 1 on both dice is scored as 25. c.  During a single turn, a player may roll the dice as many times as they desire. The score for a single turn is the sum of the individual scores for each dice roll. d.  The first player to reach the goal score wins unless a player scores higher subsequently in the same round. Therefore, everyone in the game must have the same number of turns. Execution and User Input This program is quite interactive with the user(s) and will take in the following information; please review the sample input / output sessions for details; we describe them again here emphasizing input. The program will prompt for the number of…

(Target-Heart-Rate Calculator) While exercising, you can use a heart-rate monitor to see thatyour heart rate stays within a safe range suggested by your trainers and doctors. According to the American Heart Association (AHA) (www.americanheart.org/presenter.jhtml?identifier=4736), theformula for calculating your maximum heart rate in beats per minute is 220 minus your age in years.Your target heart rate is a range that is 50–85% of your maximum heart rate. [Note: These formulas areestimates provided by the AHA. Maximum and target heart rates may vary based on the health, fitness andgender of the individual. Always consult a physician or qualified health care professional before beginning ormodifying an exercise program.] Create a class called HeartRates. The class attributes should include theperson’s first name, last name and date of birth (consisting of separate attributes for the month, dayand year of birth). Your class should have a constructor that receives this data as…
