3 hours is longer than 175 minutes. An hour is 60 minutes long, so just multiply that by 3 and compare your answer to 175.
60 x 3 = 180
180 > 175
Therefore, 3 hours is longer than 175 minutes.
Hope this helps!
Answer:
Probability of chossing a face card and the month of june = 0.019
Step-by-step explanation:
Let A be the event that a face card is chosen from a deck of 52 cards
And
B be the event that a month is being chosen from 12 months of an year
So,
n(S)for A=52
n(S)for B=12
As a deck of card has total of 12 face cards so
P(A)=12/52
=3/13
P(B)=1/12
As both the events are independent, the probability of A and B is the product of both events’ probabilities.
P(A and B)= P(A)*P(B)
=3/13*1/12
=3/156
=0.019
Answer: 9.4
Explanation: 8.4^2+4.3^2=
70.56+18.49=89.06
square root of 89.06 is 9.437
9.4 rounded off
169.65mm
A=2πrh+2πr2=2·π·3·6+2·π·32≈169.646
