7.381 qnd -11
2.34 and 10
3.871 and 2
7.831 and -11
Correct answer is A
\(\frac{0.0001432}{1940000}\) = k x 10n
where 1 \(\leq\) k \(\leq\) 10 and n is a whole number. Using four figure tables, the eqn. gives 7.38 x 10-11
k = 7.381, n = -11
\(\frac{1}{7}\)

\(\frac{1}{3}\)
3
Correct answer is A
\(\frac{2}{3} - \frac{1}{5}\) = \(\frac{10 - 3}{15}\)
= \(\frac{7}{15}\)
\(\frac{1}{3}\) Of \(\frac{2}{5}\) = \(\frac{1}{3}\) x \(\frac{2}{5}\)
= \(\frac{2}{15}\)
(\(\frac{2}{3} - \frac{1}{5}\)) - \(\frac{1}{3}\) of \(\frac{2}{5}\)
= \(\frac{7}{15} - \frac{2}{15}\) = \(\frac{1}{3}\)
3 - \(\frac{1}{1 \frac{1}{2}}\) = 3 - \(\frac{2}{3}\)
= \(\frac{7}{3}\)
\(\frac{\frac{2}{3} - \frac{1}{5} \text{of} \frac{2}{15}}{3 - \frac{1}{1 \frac{1}{2}}}\)
= \(\frac{\frac{1}{3}}{\frac{7}{3}}\)
= \(\frac{1}{3}\) x \(\frac{3}{7}\)
= \(\frac{1}{7}\)
If a{\(\frac{x + 1}{x - 2} - \frac{x - 1}{x + 2}\)} = 6x. Find a in its simplest form
x2 - 1
x2 + 1
x2 + 4
x2 - 4
1
Correct answer is D
a{\(\frac{x + 1}{x - 2} - \frac{x - 1}{x + 2}\)} = a{\(\frac{(x + 1)(x + 2)- (x - 1)(x - 2)}{(x - 2)(x + 2)}\)}
= 6
\(\frac{6x}{x^2 - 4}\) = 6x
a = x2 - 4

Correct answer is E
Total students = 120
grade = 18
Zo = \(\frac{18}{120}\) x \(\frac{360}{1}\)
= 54o
16667km
28850km
8333km
2233km
Correct answer is A
Length of an area = \(\frac{\theta}{360}\) x 2\(\pi\)r
Longitude difference = 147 + 153 = 30NoN
distance between xy = \(\frac{\theta}{360}\) x 2\(\pi\)R cos60o
= \(\frac{300}{360}\) x 4 x 104 x \(\frac{1}{2}\)
= 1.667 x 104km(1667 km)
