Number Operations
Distance, Speed, Time
1. A trucker drove for 4 hours at an average speed of 60 miles per hour (mph) and then for 3 hours at an average speed of 30 mph. What was his total distance traveled?
There are two parts to his travel.
Applying the formula: Distance = Speed X Time and substituting the values,
                     First part, Distance = 60  X  4 = 240 miles
              Second part, Distance = 30  X  3 = 90 miles
                              Total Distance traveled = 240 + 90

                                                         =
330 miles

Fractions
 3.
Solve the following: (i) 2⅔  X  3      (ii) +  2        (iii) 1⅝    ⅜
                         
                        2⅔  X  3           +  2                1⅝    ⅜
      
                                         8/3 X 7/2                +  = 1             13/8  X  8/3
                                                   = 56/6         and 5 + 2 = 7                    = 13/3 

                                      =
9              7 + 1 = 8                   = 4

Percent 
2.
The computer I need to buy costs $1,200.00. So far I have managed to save only 65% of the  cost. How much more money will I need to make the purchase?
                    
Percent means out of 100. Therefore 65% is 65/100
                         
Money save so far is 65/100  X  1200   =   65 X 1200 
                                                                                                          100      
                                                                                                =  780
                                                                                   That is $780.00
If the computer costs $1,200.00 and I have only $780.00, I will need then

                                        
$1,200.00 - $780.00   =   $420.00

Percent
 
4. (i) What is 14% of 250?  (ii) 40% of what number is 30? (iii) 80 is what percent of 200?
       (i)
  14% is 14/100                    (ii)  Let the number be T                  (iii)  80/200) X 100
                (14/100) X 250                          40/100 of T = 30                              (8/20) X 100 = 800/20  
   
                     = 
35                                   40T = 30 X 100                                = 40%
                                                            
T = (30 X 100) 40
                                                                                     = 3000 40

                                                                =
75


Algebra

Simple Equations
 
Solve the equations:
  
   (i) -3x = 12       (ii) 4x + 2x = 66            (iii) 5a + 3a = 120             (iv) Solve for x in: 6(x - 3) + x = 24
        
   -3x = 12              4x + 2x = 66                   5a + 3a = 120                                               6(x - 3) + x = 24
              x = 12/-3                  6x = 66
                            8a = 120                                               6x - 18 + x = 24
            
x = -4                     x = 66/6                            a = 120/8                                       7x = 24 + 18 = 42
                                      
x = 11                      a = 15                                       x = 42/7 = 6
                                                                                          
                                 x = 6


Measurement and Geometry
 Area of a Circle
1. Find the area of a circle with radius 3.5 cm.
            
  Area of the circle = πr where π = 3.14
 
              Substituting the values:
                                           Area = 3.14 X (3.5)

                                                    = 3.14 X 12.25 12.25
                                                   = 38.465 sq. cm.
 Circumference of a Circle
  2.
 What is the circumference of the same circle described above?
       
Circumference of the circle = π X diameter.
           If the radius of the circle is 3.5 cm then its diameter is 2 X 3.5 = 7 cm.
                                                      Circumference therefore is 3.14 X 7 =
21.98 cm

Perimeter of a Square
 3.
If one side of a square is 4 cm, what is the perimeter of the square?            Perimeter of the square is the total distance around  = 4 X 4 cm or 4 + 4 + 4 + 4
                                                                                            
          = 16 cm
