Answer:

  ΔABC ~ ΔADE

Corresponding sides are proportional, so we have ...

  BC/DE = AB/AD

  x/12 = 3/(3+9)

What time is it if half of what has already passed remains until the end of today?
lukranit [14]

Answer:

<h2>4 p.m.</h2>

Step-by-step explanation:

We know that a day contains 24 hours in total.

The time already passed will be represented by x.

The remaining time would be \frac{x}{2}, becasye half of what has already passed remains until the end of the day.

Basically, the sum of these two expression gives 24 hours in total.

x + \frac{x}{2} =24\\\frac{3x}{2}=24\\ x=16

Therefore, the actual time is 4 p.m.
