X=1 y=2.5 I’m not sure if that’s correct but I hope it is.
X=14
Y=14
Perimeter=56
The reason is because if you see 8 and 6 you can see that the lines are equivalent so I just assumed that the missing lines are 8 and 6. So I added the number up causing x and y to be 14 then for perimeter I simply just multiplied 14x4 which is 56.
Circumference = 2πr = 2π(1.25) = 7.85ft
I hope this answers your question and best of wishes!!
Answer:
The least amount of time (in hours) both pumps need to be open is 3 hours.
Step-by-step explanation:
According to the Question,
- Given That, A pool has two inlet pumps A and B. If pump A alone is open, it takes 12 hours to fill the pool with water. If pump B alone is open, it takes 18 hours to fill the pool with water.
Let the Capacity of the Pool is 36Litre.
- Thus, If pump A alone is open, it takes 12 hours to fill the pool with water. thus the Efficiency of Pipe A is 3 ltr/hour.
- And, If pump B alone is open, it takes 18 hours to fill the pool with water. thus the Efficiency of Pipe B is 2 ltr/hour.
If the pool needs to be filled in 10 hours the least amount of time (in hours) both pumps need to be open is 3 hours.
Note:- if 3 hour both pipe open so 3 x (5) = 15 ltr Pool is Filled.
Now For Remaining 7 hour Pipe A with Efficiency 3 ltr/hour is open alone to fill the pool Remaining 7 x 3 = 21 ltr . Total 21+15 = 36ltr .
