Answer:
The number of pools clean per hour is 1.5
Step-by-step explanation:
Given as :
The number of pools clean in 8 hours = 12
The number of pools clean in 7.5 hours = 9
Let The number of pools they clean per hours = x
I.e x = +
Or, x =
Or, x =
∴ x =
I.e x = 1.5
Hence The number of pools clean per hour is 1.5 Answer
Answer:
The value of k is and The value of p is - 23
Step-by-step explanation:
Given equation as :
81 y - 17 = k² y + 6 + p
The equation has real solution ,
Now for real solution the equation have no solution
∵ The equation has no solution the ,
The coefficient of y must be equal
I.e 81 = k²
Or, k =
∴ k =
Again , If the coefficient of y is same then the equation is written as
6 + p = - 17
or, p = - 17 - 6
or, p = - 23
Hence The value of k is and The value of p is - 23 Answer
