Answer:
Pool will be filled in 280 hours
Step-by-step explanation:
Inlet pipe fills in 40 hours = 1 pool
Inlet pipe fills in 1 hours =
Drain pipe empty in 42 hours = 1 pool
Drain pipe empty in 1 hour =
If both pipes are opened together
then in pool fills in 1 hour = -
on simplifying the right side ,we get
=
=
pool fills in 1 hour
1 pool will be filled in 840 hours
pool is filled
empty pool = 1 - =
therfore pool will be filled in
X 840 =
= 280 hours
Answer:
64 degrees
Step-by-step explanation:
Since the triangles are similar they have the same angle measures
∠P = ∠S ∠R =∠U ∠Q=∠T
We know 2 of the angle measures: ∠S and ∠R, and since they are similar we know ∠P and ∠U
In triangles the sum of all angle measures is always 180 degrees, so we can solve for ∠Q with this formula
subtract 116 from both sides
Therefore ∠Q is equal to 64 degrees
