The side lengths of A'A and B'B are 18 and 9 respectively.
What are similar triangles?When the respective sides are proportional and the corresponding angles are congruent, two triangles are said to be similar.
Given that, segment A'B' is parallel to segment AB.
Let A'A =x and B'B = y.
Since the segments are parallel the triangles ΔA'B'C and ΔABC are similar.
As per the property of similar triangles, it follows:
12/8 = (12 + x)/20
12 + x = (12/8)20
x = 18
And,
6/8 = (6+y)/20
6 + y = (6/8)20
y = 9
Hence, the side lengths of A'A and B'B are 18 and 9 respectively.

Answer:

Step-by-step explanation:
It is a parallelogram so the opposite angles are the same.
All angles sum to 360 degrees.
This means that the adjacent angles sum to 180 degrees.
4a + 11 + 9a = 180 = 13a + 11
13a = 169

You are selling candy bars. It cost $140 for
a startup fee and $1.50 per candy bar. Your
income is based on the fact that you are
selling the candy bars for $4.00 each.
1) What is the profit from selling 40 candy bars? The profit is $ ........
2) What is the profit selling 100 candy bars? The profit is $ .......
3) In order to break even you must sell .......... candy bars.
4) The minimum of candy bars you must sell in order to start making positive profit is .......... candy bars.
Answer:
Profit = price charged - cost of goods
$10 = Price - 30.00
$40 = Price of one box
So, they have to charge $40 per box. Since there are 50 bars in each box, the price per bar has to be:
$40.00/50 bars = $0.80 per bar
You can check this....
0.80 x 50 bars = $40.00 <<< this is the total income from the sale of one box.
since each box costs $30.00, they've made $10.00 on each box.

Jordan walks 250 m North towards school. He forgets his backpack and walks 250 m South back to his house. He then finds his backpack and walks 900 m North. He gets to school in 9 minutes. What is his velocity in meters per minute
Answer:
10 m / minute
Step-by-step explanation:
Starting position = North ; back to North gives a Displacement of 0 ; the from that position to 900 m south gives a final Displacement of 900
Displacement / time
Displacement = 900
Time = 9 minutes
900 / 9
= 10 m / minute
