Sebastian swan laps every day in the community swimming pool. He swam 45 minutes each day, 5 days each week, for 12 weeks. In that time, he swam 1800 laps. What was his average rate in laps per hour?
Let us convert time taken into hours as:


1 hour = 60 minutes. To convert minutes into hours, we will divide total minutes by 60.

Now, we will divide 1800 by 45 to find average rate in laps per hour as:


Therefore, Sebastian's average rate is 40 laps per hour.
Answer:
The two triangles are related by Side-Side-Side (SSS), so the triangles can be proven congruent.
Step-by-step explanation:
There are no angles that can be shown to be congruent to one another, so this eliminates all answer choices with angles (SSA, SAS, ASA, AAA, AAS).
This leaves you with either the HL (Hypotenuse-Leg) Theorem or SSS (Side-Side-Side) Theorem. We could claim that the triangles can be proven congruent by HL, however, we aren't exactly sure as to whether or not the triangles have a right angle. There is no indicator, and in this case, we cannot assume so.
This leaves you with the SSS Theorem.
.2 is 2/10 while .5 is 1/2. 1/2 is much larger than 1/5 (which is 2/10 reduced).
Answer:
GH = 6 units
Step-by-step explanation:
Calculate GC using Pythagoras' identity in right triangle GCE
GC² = 9² + 12² = 81 + 144 = 225 ( take the square root of both sides )
GC =
= 15
GH + HC = GC ← HC is the radius of the circle and HC = 9, thus
GH + 9 = 15 ( subtract 9 from both sides )
GH = 6
