2. More Shapes
by CodeChum Admin
Since we are interested with drawing in this quiz (it seems), consider a Shape object. We know that for regular shapes (like Rectangle and Circle), they have properties like area and perimeter. Let's also assume that these Shapes have color (simply a String for the purpose of this quiz) and whether the shapes are filled with this color or not (boolean).

You probably are fond of games. This quiz though is not that complicated. You are simply going to work with a point on a screen, and a circle on a screen as well. And let's consider them as the characters in the game. We are going to call both of these characters as Movable objects. Objects are said to be Movable if they can be moved around the screen. The following simple movements are allowed:
public void moveLeft();
public void moveRight();
public void moveUp();
public void moveDown();
public void display();
public void moveLeft();
public void moveRight();
public void moveUp();
public void moveDown();
public void display();Input
- 1 moveLeft()
- 2 moveRight()
- 3 moveUp()
- 4 moveDown()

a change in consumer’s income affect his equilibrium?
1. A tour operating firm plans to take tourists between Addis Ababa and Jimma. its estimated cost function given by C =100 +50 N+4N2 (Where N denotes the number of passengers per day)
A. State the average cost function.
B. State the marginal cost of the average cost function.
C. Find the number of passengers per day that minimize average cost.
D. What is the minimum average cost at the optimal level of passenger?
E. What will be the total cost at the optimal level?
Write the Python code of a program that reads a student’s mark for a single subject, and prints out the corresponding grade for that mark. The mark ranges and corresponding grades are shown in the table below. You need to make sure that the mark is valid. For example, a student cannot receive -5 or 110 marks. So, the valid marks range is 0 to 100.
Suppose that you are travelling in the Space Shuttle Endeavor on a journey to Mars. The atmosphere (of the vehicle) consists of 20% oxygen and 80% helium by volume. It was noticed before take off from the Kennedy Space Center that there is a small leakage which if unchecked, would lead to a continual loss of gas at a rate of 0.05 atm/day through effusion. If the temperature in the space shuttle is maintained at 22°C and the volume of the vehicle is 15,000 liters. Calculate the amounts of helium and oxygen in grams that must be stored on a 5-day journey to allow for the leakage.
A vessel of volume 5 liters was filled with 2 moles of hydrogen gas (a), then a further
1 mole of chlorine gas (b), and then the mixture was sparked leading to the formation of 1 mole of HCI (g) (c). What are the partial pressure of the components
and the total pressure of the system at the final stage. The temperature being 25°C throughout.
If a is equal to 1.2 ± 0.1cm, b=2.0 ± 0.2cm, c=1.05±0.05cm, calculate the following with the errors and standard errors
(i) ab/C³
(ii) ABC
(iii) C²a³/b²
