7
Clocks can display up to the number 59 (60 minutes in an hour). If you list all of the perfect squares that are under 59, you will find that there is 7 of them: 1, 4, 9, 16, 25, 36, and 49.
Answer:
(C)Angle MRN and Angle NRO
Step-by-step explanation:
A diagram of the given problem is drawn and attached below.
From the diagram:
Option A: Angle PRL and Angle LRM = Angle PRM which is not 180 degrees.
Option B: Angle ORP and Angle MRN are vertically opposite angles and are therefore not linear pairs.
Option C: Angle MRN and Angle NRO are on the line ORM and therefore forms a linear pair.
<u>Therefore, the correct option is C.</u>
The best and most correct answer among the choices provided by your question is the first choice or letter A.
The conditional statement "If it is January, then it is winter in the United States," is converse of the conditional.

The question didn't make sense, could you add more to it?
F = kq2 / r2
q = ne
F = k(ne)2 / r2
n = âš(r2F / ke2) = (r/e) âš(F/k)
k = 9 x 109 Nm2/C2
e = 1.6 x 10-19 C
n = [(4.2 x 10-10) / (1.6 x 10-19)] âš[(5.2 x 10-9) / (9 x 109)] ≅ 1.995 ≅ 2
