How good are you with figures and formulas? Find out with these Mathematics past questions and answers. This Test is useful for both job aptitude test candidates and students preparing for JAMB, WAEC, NECO or Post UTME.
9.0 m
12. 0 m
8.8 m
10.4 m
Correct answer is B
\(\tan 45 = \frac{x}{10.4}\) = 10.4m
\(height of the tree is equal to 1.6m + 10.4m=12m\)
Find the coordinates of the mid-point of x and y intercepts of the line 2y = 4x - 8
(2, 0)
(1, -2)
(-1, -2)
(1, 2)
Correct answer is B
2y = 4x - 8 \(\implies\) y = 2x - 4.
When x = 0, y = -4.
When y = 0, x = 2.
The midpoint between (0, -4) and (2, 0) = \((\frac{0 + 2}{2}, \frac{-4 + 0}{2})\)
= \((1, -2)\)
12
20
40
10
Correct answer is A
The formula for the sum of the interior angles of a regular polygon = (2n - 4) x 90°
Given: Sum = 20 right angles
(2n - 4) x 90° = 20 \times 90°
⇒ 2n - 4 = 20
2n = 24; n = 12.
304π/3 cm3
144π cm3
128π cm3
72π cm3
Correct answer is A
Volume of a frustrum with top of radius R and bottom r and height h = \(\frac{1}{3} \pi (R^{2} + Rr + r^{2})\)
V = \(\frac{1}{3} \pi \times 4 \times (6^2 + 6 \times 4 + 4^2)\)
= \(\frac{304}{3} \pi cm^{3}\)
Find the equation of the set of points which are equidistant from the parallel lines x = 1 and x = 7
y = 3
x = 3
x = 4
y = 4
Correct answer is C
The line equidistant from x = 1 and x = 7 is
\(x = \frac{1 + 7}{2} \implies x = 4\)
