Detailed Solution0.000215215 x 0.000028= 215 x 10^{4} x 28 x 10^{4} = 215 x 28 x 10^{66} = 6020 x 10^{12} = 6.020 x 10^{3} x 10^{12} = 6.02 x 10^{3  12} = 6.02 x 10^{9} 

2. 
Factorize: x + y  ax = ay A. (x  y)(1  a) B. (x + y)(1 + a) C. (x + y)(1  a) D. (x  y)(1 + a)
Show Content
Detailed Solutionx + y  ax = ay= (x + y) a(x + y) = (x + y)(1  a) 

3. 
A car uses one litre of petrol for every 14km. If one of petrol cost N63.00, how far can the car go with N900.00 worth of petrol? A. 420km B. 405km C. 210km D. 200km
Show Content
Detailed Solution1 litre = N63.00xlitres = N900.00 x x N63 = N900 x 1 litre x = \(\frac{900}{63} \times litre\) x = \(\frac{100}{7}\) litres Also, 1 litre = 14km \(\frac{100}{7}\) = y y x 1 litre = \(\frac{100litre}{7}\) x 14km y = 20km 

4. 
Correct 0.002473 to 3 significant figure A. 0.002 B. 0.0024 C. 0.00247 D. 0.0025 
C 
5. 
Simplify 1\(\frac{1}{2} + 2\frac{1}{3} \times \frac{3}{4}  \frac{1}{2}\) A. 2\(\frac{1}{3}\) B. 2\(\frac{1}{4}\) C. 2\(\frac{1}{8}\) D. 2\(\frac{3}{4}\)
Show Content
Detailed Solution1\(\frac{1}{2} + 2\frac{1}{3} \times \frac{3}{4}  \frac{1}{2}\)\(\frac{3}{2} + \frac{7}{3} \times \frac{3}{4}  \frac{1}{2} = \frac{3}{2} + \frac{7}{4}  \frac{1}{2}\) = \(\frac{6 + 7  2}{4} = \frac{11}{4}\) = 2\(\frac{3}{4}\) 

6. 
The sum of 2 consecutive whole numbers is \(\frac{5}{6}\) of their product, find the numbers A. 3, 4 B. 1, 2 C. 2, 3 D. 0, 1
Show Content
Detailed SolutionLet the no. be x and x + 1x + (x + 1) = \(\frac{5}{6}\) of x(x + 1) 2x + 1 = \(\frac{5}{6}\) x(x + 1) 6(2x + 1) = 5x^{2} + 5x 12x + 6 = 5x^{2} + 5x 5x^{2} + 5x  12x  6 = 0 5x^{2}  7x  6 = 0 5x^{2}  10x + 3x  6 = 0 5x(x  2) + 3(x  2) = 0 (5x + 3)(x  2) = 0 (5x + 3)(x  2) = 0 (5x + 3) = 0 x  2 = 0 for (5x + 3) = 0 5x = 3 

7. 
A casting is made up of Copper and Zinc. If 65% of the casting is Zinc and there are 147g of Copper. What is the mass of the casting? A. 320g B. 420g C. 520g D. 620g
Show Content
Detailed Solution%Zinc + %Copper = 100%65% + %Copper = 100% %Copper = 100%  65% = 35% %Copper = \(\frac{\text{Mass of % Copper}}{\text{Mass of Casting}}\) x 100% Mass of Casting = \(\frac{147}{35}\) x 100% = 420g 

8. 
Given that P = {x : 1 \(\leq x \leq 6\)}, and Q = {x : 2 \(\leq x \leq 10\)} where x is an integer. Find n(P \(\cap\) Q) A. 5 B. 6 C. 8 D. 10
Show Content
Detailed SolutionP = {1, 2, 3, 4, 5, 6}; Q = {3, 4, 5, 6, 7, 8, 9}P \(\cap\) Q) = {2, 3, 4, 5, 6} n(P \(\cap\) Q) = 5 

9. 
The sum of 6 and onethird of x is one more than twice x, find x A. x = 7 B. x = 5 C. x = 3 D. x = 2
Show Content
Detailed Solution6 = \(\frac{1}{3}x\) = 1 + 2x6 = 1 = \(\frac{2x}{1}  \frac{x}{3}\) 5 = \(\frac{6x  x}{3} = \frac{5x}{3}\) 5 = \(\frac{5x}{3}\) 3 x 5 = 5x 15 = 5x x = \(\frac{15}{5}\) = 3 

10. 
Given that = {x: 2 < x \(\leq\) 9}, where x is an integer what is n(T)? A. 9 B. 10 C. 11 D. 12
Show Content
Detailed SolutionT = {1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9}n(T) = 11
