Can someone please help me on this math problem!!?
olasank [31]

check the picture below.


since we know all those interior points are midpoints, then those interior lines are midsegments, recall the midsegment is half the parallel base.

in this case, the green DF || AC, and since AC is 50, DF is half that, 50/2.

A bag contains counters that are red, black , or green . 1/3 of the counters are red 1/6 of the counters are black There are 15
Nadya [2.5K]

Answer:

There are 5 black counters in the bag.

Step-by-step explanation:

15 green counters in the bag

The proportion of green counters is given by:

p = 1 - (\frac{1}{3} + \frac{1}{6}) = 1 - (\frac{2}{6}+\frac{1}{6}) = 1 - \frac{3}{6} = 1 - \frac{1}{2} = \frac{2}{2} - \frac{1}{2} = \frac{1}{2}

So, we have that, the total is x. So

\frac{x}{2} = 15

x = 30

There are 30 total counters.

How many black counters are in the bag ?

A sixth of the counters are black. So

\frac{1}{6} \times 30 = \frac{30}{6} = 5

There are 5 black counters in the bag.
