To find the rate at which the lawn sprinkler would fill the pool if used alone, subtract the rate of the hose from the combined rate. The equation is rs = 1/5 - 1/8.
To determine the rate at which the lawn sprinkler would fill the pool if used alone, we can set up an equation using the concept of rates. Let r be the rate at which the sprinkler fills the pool. If it takes 8 minutes for Byron to fill the pool with just the hose, then the rate of the hose alone is 1 pool/8 minutes, or rh = 1/8. If it takes 5 minutes to fill the pool when both the hose and sprinkler are used together, then the combined rate is 1 pool/5 minutes, or rc = 1/5.
The rate of the sprinkler alone, rs, can be determined by subtracting the rate of the hose from the combined rate. Thus, we have rs = rc - rh. Substituting the given values, we have rs = 1/5 - 1/8.
Therefore, the equation that can be used to determine the rate at which the lawn sprinkler would fill the pool if used alone is rs = 1/5 - 1/8.

Answer:
GF = GE that prove G is the mid-point of EF
Step-by-step explanation:
In the Parallelogram ABCD
∵E is the mid-point of AB
∵F is the mid-point of CD
∵AB = CD opposite sides in the parallelogram
∴EB = DF⇒(1)
∵AB // CD opposite sides in the parallelogram
∴m∠EBD = m∠FDB alternate angles ⇒(2)
∵BD intersects EF at G
∴m∠BGE = m∠DGF vertically opposite angles ⇒(3)
By using (1) , (2) and (3) you can prove:
ΔBGE is congruent to ΔDGF ⇒ AAS
∴GF = GE
∴G is the mid-point of EF
