Six friends have organized themselves by age. molly is older than jenna, but younger than brett. brett is younger than cynthia, but older than jenna. jenna is older than tina and marcus. marcus is younger than cynthia and tina. who is the oldest and who is the youngest? explain your answer.

 Youngest = Marcus

                Oldest = Cynthia

Step-by-step explanation:

Molly is older than Jenna, but younger than Brett:

Jenna < Molly < Brett

Brett is younger than Cynthia, but older than Jenna:

Jenna < Molly < Brett < Cynthia

Jenna is older than Tina and Marcus:

Tina & Marcus < Jenna < Molly < Brett < Cynthia

Marcus is younger than Cynthia and Tina:

Marcus < Tina < Jenna < Molly < Brett < Cynthia

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.

hope this by jack monhen

the answer should be 3.54 g/cm^3
