(21cm3, 3cm3)
(24cm3, 3cm3)
(24cm3, 21cm3)
(72cm3, 9cm3)
(63cm3, 9cm3)
Correct answer is B
Vol. of the 1st section is side x height
vol. = 3 x 8
= 24cm3
vol. of the second section is 3 x 1 = 3
= 24cm3, 3cm3
58 sq.cm
34 sq.cm
132 sq.cm
77 sq.cm
66 sq.cm
Correct answer is E
Given: length of the arc AOB = 22cm ; L = 6cm
Curved surface area of cone = \(\pi\)rl
Length of an arc = \(\frac{\theta}{360}\) x 2 \(\pi\)L
= 22cm
but length of an arc = circumference of the cone = 2\(\pi\)
where r is the radius of the cone circle
2\(\pi\)r = 22, r = \(\frac{22}{2\pi}\)r
= 11 x \(\frac{7}{22}\)
= \(\frac{7}{2}\)
curved surface area = \(\pi\)rl
= \(\frac{22}{7}\) x \(\frac{7}{2}\) x 6
= 66 sq.cm
The solution to the simultaneous equations 3x + 5y = 4, 4x + 3y = 5 is
(\(\frac{-13}{11}, \frac{1}{11}\))
(\(\frac{13}{11}, \frac{1}{11}\))
(\(\frac{13}{11}, \frac{-1}{11}\))
(\(\frac{11}{13}, \frac{1}{11}\))
(13, 11)
Correct answer is B
3x + 5y = 4, 4x + 3y = 5
3x + 5y = 4 x 4
4x + 3y = 5 x 3
12x + 20y = 16.....(i)
12x + 9y = 15.......(ii)
subtract eqn.(ii) from eqn.(i)
11y = 1
y = \(\frac{1}{11}\)
12x + 20 x \(\frac{1}{11}\) = 16
12x = \(\frac{156}{11}\)
x = \(\frac{13}{11}\)
= \(\frac{13}{11}, \frac{1}{11}\)
N220.00
N222.00
N201.40
N202.00
N180.80
Correct answer is B
3 kg of garri at N13.00 per kg = N39.00
half a cow = N160.00
24 oranges at 10k each = N2.40
balance = N20.60
Adding all together = N222.00
The solution to the quadratic equation 5 + 3x - 2x2 = 0 is
(\(\frac{5}{2}\), 1)
(5, 3)
-(\(\frac{5}{2}\), -1)
(\(\frac{5}{2}\), -1)
Correct answer is D
5 + 3x - 2x2 = 0, (x + 1)(5 - 2x) (expand to check)
(x + 1)(5 - 2x) = 0
when x = 1 = 0, x = -1
when 5 - 2x = 0, x = \(\frac{5}{2}\) - 1
