The correct answer here is A because it asks to prove congruence. Since we know line ST is the BISECTOR of PR, we know that Q is the middle point and indeed PQ and RQ are congruent lines.
Answer:
9 1/16 in
Step-by-step explanation:
When chords cross, the distances from their point of intersection to the circle have the same product for each chord. For the 9-in chord, those two distances are 4.5 inches. For the diameter, the distances are 4 in and (d-4) in, where d is the diameter of the circle. Then ...
4.5^2 = 4(d -4)
d = 4.5^2/4+4 = 9 1/16 . . . . inches
The diameter is 9 1/16 inches.

<em>Comment on the diagram</em>
The fact that the 9-inch chord looks very much like a diameter tells you the actual diameter won't be much different than that. These figures are not always drawn to scale, and are sometimes misleading. However, if the actual diameter were in the neighborhood of 16 inches, the perpendicular bisector shown would need to be about 1.4 inches instead of 4 inches.
The equation that represents the statement the product of 1/5 and a number is equal to 1 1/2 is n/5 = 1¹/₂.
Since the question says, the product of 1/5 and a number is equal to 1 1/2.
This is a word problem
Let n be the number.
<h3 /><h3>Identifying the product </h3>
Since it says the product of a number n and 1/5, we have n × 1/5 = n/5
It says this product equals 1¹/₂.
<h3 /><h3>Equating the expressions</h3>
So, we equate both expressions.
So, n/5 = 1¹/₂.
So, the equation that represents the statement the product of 1/5 and a number is equal to 1 1/2 is n/5 = 1¹/₂.
