A tap can fill a bucket in 6 hours. After half the bucket is filled, three more similar taps are opened. What is the total time

777dan777 [17]

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 = $\frac{1}{6}$

Part filled by four taps in one hour = $4(\frac{1}{6})=\frac{4}{6}=\frac{2}{3}$

Given, that after half the bucket is filled, three more similar taps are opened

Then the remaining part = $1-\frac{1}{2}=\frac{1}{2}$

Time taken to fill the half of the bucket= $(\frac{1}{2} )(\frac{2}{3})=\frac{3}{4}$ hours

Convert the hours to minutes

$(\frac{3}{4})60=45$ 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

Help me please !!!!!!!!

y=5/3x

this is because f(x)=x is one of (identity function) the 12 basic functions and when you multiply it it will shift it on the y axis

If you were to do y=x+5/3 it would make a horizontal shift to the left 5/3

So the unit your on is mostly about knowing the number located in the function that will make the graph shift different ways

Answer:

-3x³ - 4x² + x - 9

Step-by-step explanation:

-5x³ + 2x² + x - 7

- <u>(-2x³ + 6x² + 0 + 2)</u> remember: when you subtract, you 'add the opposite'

-3x³ + (-4x²) + x + (-9)
