Show answer & explanation
Correct answer: C
A. The angle between the hour hand and the minute hand at 2:40 PM is 130°
Minute hand angle:
40×6=240°
Hour hand angle:
2×30+40/60×30=60+20=80°
Angle between hands:
240−80=160°
So statement A is false.
B. If x3=1331, then x=11
113=11×11×11=1331
So statement B is true.
C. The area of a 1.0 m wide track around a rectangular sports field of dimensions 20 m×18 m is 80 m2
Outer dimensions:
(20+2)×(18+2)=22×20=440
Inner area:
20×18=360
Track area:
440−360=80 m2
So statement C is true.
D. (1 / 8 of 1000)1/3 =1251/3=5
So statement D is true.
Correct statements are:
B, C, and D Only
