30o
60o
112.5o
157.5o
Correct answer is D
Rice = 75g, Margarine = 40g, Meat = 105g, Bread = 20g, Total = 240
Angle of sector represented by meat
= \(\frac{105}{240}\) x \(\frac{360°}{1}\) = 157.5°
2\(\sqrt{5}\)
3
4
4\(\sqrt{3}\)
Correct answer is D
xz2 = 62 + 62
36 + 36 = 72
xz = \(\sqrt{72}\)
6\(\sqrt{2}\) = xT
\(\frac{6\sqrt{2}}{2}\) = \(\frac{3}{\sqrt{2}}\)
OT2 = 52 + (3\(\sqrt{2}\))2 = 25 + 18
OT = 4\(\sqrt{3}\)
440\(\pi\)cm3
1100\(\pi\)cm3
4400\(\pi\)cm3
1100\(\pi\)cm3
Correct answer is A
Volume of cylinder pip (V) = \(\pi\)h(R\(^2\) - r\(^2\))
= 100\(\pi\)(7.2\(^2\) - 2.8\(^2\))
= 100\(\pi\)(51.84 - 7.84)
= 100\(\pi\) x 44
= 440\(\pi\)cm\(^3\)
336
420
576
720
Correct answer is A
Total floor area = 720 x 420
Area of one tile = 30 x 30
No. of tile required = \(\frac{720 \times 420}{30 \times 30}\)
= 24 x 14
= 336 tiles
4sin2 x - 3 = 0, find x if 0 \(\geq\) x \(\geq\) 90o
30o
45o
60o
9o
Correct answer is C
4 sin2x - 3 = 0
sin2x = \(\frac{3}{4}\)
Sin x = \(\pm\) \(\sqrt{\frac{3}{4}}\)
= \(\pm\) \(\sqrt{\frac{3}{4}}\)
= 60o
