In △abc, point p∈ ac with ap: pc=1: 3, point q∈ ab so that aq: qb=3: 4, find the ratios apbq : apbc and aaqp : aabc.

1. If AP : PC = 1 : 3, then AP = x, PC = 3x.

2. If AQ : QB = 3 : 4, then AQ = 3y, QB = 4y.

3. Find the area of triangles AQP and ABC:

Then

4. Note that

From the previous two ratios you have that:

Then

probability for j is 1/4

while

a is 1/6

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
