\(5\frac{1}{2}cm\)
\(4\frac{2}{3}cm\)
\(3\frac{1}{2}cm\)
\(2\frac{1}{3}cm\)
Correct answer is D
\(r=\frac{\theta \times l}{360^{\circ }}\\
r=?, \theta =60^{\circ }\), l = radius of the orginal sector of a circle = 14cm
\(r=\frac{60\times 14}{360}=\frac{7}{3}=2\frac{1}{3}cm\)
2.5cm
3.0cm
3.5cm
4.0cm
Correct answer is D
\(5^{2}=3^{2}+x^{2}\\
25-9=x^{2}\\
16=x^{2}\Rightarrow x=4.0\)
The area of a square field is 110.25m2. Find the cost of fencing it round at N75.00 per meter square
N1,575.00
N3,150.00
N4,734.30
N8,268.75
Correct answer is D
N75.00 x 110.25 = N8,268.75
If \(8^{x+1}=\frac{1}{4}\), find x
\(-\frac{5}{3}\)
-1
\(-\frac{1}{3}\)
\(\frac{1}{3}\)
Correct answer is A
\(8^{x+1}=\frac{1}{4}\\
2^{3(x+1)}=2^{-2}\Rightarrow 3(x+1)=-2\Rightarrow 3x+3=-2\\
3x=-5\Rightarrow x=\frac{5}{3}\)
Solve the simultaneous equation: x+y=2 and 3x-2y=1
x=2 and y=1
x=1 and y=1
x=1 and y=2
x=-1 and y=1
Correct answer is B
x + y = 2 --- eqn I
3x - 2y = 1 --- eqn II
Multiply eqn by 2
2x + 2y = 2 --- eqn III
Subtract eqn II from eqnI
5x = 5 => x = 1
Substitute 1 for x in eqn 1
1 + y = 2 => y = 1
