Find F when 

Substitute 10 for C



Answer:
4 cm (A)
Step-by-step explanation:
triangle BAC is just a larger version of triangle EAD. given that ED is 5cm, and BC is 10cm, triangle BAC must be twice the size of EAD. since the ratio of AD to ED is 4:5, and BC is twice the size, all we need to do is multiply both sides by 2 to find length AC. 4*2 = 8. now we can subtract length AD from AC to get CD. 8 - 4 = 4.
sorry if what i wrote is a little confusing
Answer:

Step-by-step explanation:
Let points D, E and F have coordinates
and 
1. Midpoint M of segment DF has coordinates

2. Midpoint N of segment EF has coordinates

3. By the triangle midline theorem, midline MN is parallel to the side DE of the triangle DEF, then points M and N are endpoints of the midsegment for DEF that is parallel to DE.
Ill show you step by step.
This is what the equation should look like
Y=Initial value(1+/- Increasing or Decreasing value)^2 Which stands for time

So you need to do 1.0525 to the 2nd power Which equals 1.10775625
So now you need to do 15,000(1.10775625)

The mean for the second week increased by $0.40.
The mean for the first week is found by adding the data points and dividing by 5:
(12.99+10.50+9.89+6.90+7.58)/5 = $9.57
Since the cost increased by $2 the second week, we add two to the data points before dividing by 5:
(12.99+10.50+9.89+6.90+7.58+2)/5 = $9.97
To find the increase in means, subtract them:
9.97-9.57 = $0.40.
