The 4 is in the tenth place...so you have to look at the number beside it to see if you round up or down. It's a 6, which is greater than 5 so you round up.
3.5
Answer:
The answer is C, 17 and | -17|
Step-by-step explanation:
We can solve this using the process of elimination.
Looking at the first one, we know that those | | around the 7 mean to find the absolute value. The absolute value is the number of units the number is from zero, and it is always positive. This means that it is saying 7 and -7. Those are opposites, so we know that this isn't right.
17 and -17 are opposites, since the opposite of a positive is a negative.
The last one is the same. 71 and -71 are opposites. That leaves us with C.
Remember that those | | mean to find the absolute value of. -17 is 17 unites from zero. So is 17 the oppostie of 17? No, so these are not opposites, and therefore are our answer.
The total time taken to fill the bucket completely is 3 hours 45 minutes
The time taken to fill the bucket by one tap= 6 hours
Then the time take by one tap to fill half of the bucket= 3 hours
Part filled by one tap in one hour =
Part filled by four taps in one hour =
Given, that after half the bucket is filled, three more similar taps are opened
Then the remaining part = 
Time taken to fill the half of the bucket= 
hours
Convert the hours to minutes
minutes
Therefore,
Total time taken to fill the bucket= The time taken by one tap to fill half of the bucket+ Time taken by 4 taps to fill the half of the bucket
=3 hours+ 45 minutes
=3 hours 45 minutes
Hence, The total time taken to fill the bucket completely is 3 hours 45 minutes

Answer:
9 sqrt(2) /2 = PQ
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp/ hypotenuse
sin 45 = PQ = 9
9 sin 45 = PQ
9 sqrt(2) /2 = PQ
