The time it will take to fill the vat if both pipes are left open is = 4.3 hours
<h3>Calculation of time taken to fill vat</h3>
The number of pipes a vat has = 2
The time it takes the inlet pipe to fill the vat = 3hrs
The time it takes the outlet pipe to empty the vat= 10hrs
Therefore, the time it will take to fill the vat if both pipes are left open is;
1/t = 1/3-1/10
1/t = 7/30
Make t the subject of formula,
t = 30/7
t= 4.3 hours

Answer:
5π
Step-by-step explanation:
just need to find half of the circumference
Answer:
The correct option is C) 36
Step-by-step explanation:
Consider the provided table:
x - y
1 - 1
2 - 4
3 - 9
4 - 16
Observe the pattern:
If we square the x value we can find the corresponding y value.
For example
2² = 4
Where 2 is x value and 4 is corresponding y value, similarly
3² = 9
4² = 16
Now we need to find the y value when x=6.
To find this simply square the x value that will gives us the corresponding y value.
6² = 36
Hence, the correct option is C) 36
Answer:
41
Step-by-step explanation:
1. Multiply 5 by 6 in order to get to the 9th number. (5 places away, 4 were given.) Also, notice that the difference between all of the numbers are consistently 6.
2. Add 30 to 11, which gives you 41.
It has three lines of symmetry.
