Answer:
<em>SR is a secant of circle P</em>
Step-by-step explanation:
see attachment for the missing figure.
In the circle P,
<u>Option A:</u>
N is a point of tangency on circle P.
As Q is a point of tangency of circle P. Therefore, the statement is not true.
<u />
<u>Option B:</u>
PT is a secant of circle P.
As PT is a radius of the circle P. Therefore, the statement is not truee.
<u>Option C:</u>
SR is a secant of circle P.
It is true by the above bulleted points.
<u>Option D:</u>
VU is a tangent of circle P.
As VU is a diameter of the circle P. Therefore, the statement is not true
Therefore, the true statement is <em>SR is a secant of circle P</em>
Answer:
Step-by-step explanation:
Let's call Joseph "J", Mark "M", and Kevin "K" for ease. We need a system of equations to solve this, 3 equations for 3 unknowns. The first equation is
J + M = 230. The second equation is
J + K = 130. The third equation is
M = 3K. Sub that 3K into the first equation and get
J + 3K = 230. Now take th second equation and solve it for J:
J = 130 - K. Now sub 130 - K into the re-written first equation to get a whole new equation in terms of K only:
130 - K + 3K = 230 and
2K = 100 so
K = 50
Kevin has $50
