Answer:
45°, 54°, 81°
Step-by-step explanation:
5x+6x+9x=20x
20x --> 180
x --> 9
for each angle :
5x --> 45°
6x --> 54°
9x --> 81°
Time = Distance / Speed
1. 240/60 = 4 Hours
2. 6/3 = 2 Hours
3. 90/30 = 3 Hours
Therefore the correct answer is 3.
Answer:
73
Step-by-step explanation:
17×2=34
180-34=146
146/2=73
=73
Answer:
-8
Step-by-step explanation:
Answer:
Probabilty of first component drawn defective= 0.1161
Probability of second component drawn defective= 0.1560
Step-by-step explanation:
Total component = 9
Defective component= 3
Non-defective component= 6
Probability of defective= 3/9
= 0.3333
Probabilty of non defective= 1-0.3333
= 0.6666
Probabilty of first component drawn is defective
= 9C1(0.333)¹(0.6666)^8
= 9(0.3333)(0.0387)
= 0.1161
Probabilty of second component is defective
= 8C1(0.3333)¹(0.6666)^7
= 8(0.3333)(0.0585)
= 0.1560
