1)
you have similar triangles(ABC, ADE), so their side length ratios are equal

8/2=4/CE
CE*4=4
CE=1


2)
angle bisector theorem:
CD/DA=BC/BA

CD/DA=10/8
I:AD=10CD/8

we also know AC=AD+CD=6
II:CD=6-AD

insert II in I:

AD=10(6-AD)/8
=5(6-AD)/4
=(30-5AD)/4
4AD=30-5AD
9AD=30
3AD=10
AD=10/3

wolverine [178]

Answer:

Edible fruit amount is 4.8 ounce to 5.6 ounce  

Step-by-step explanation:

Given as

The seed and skin of avocados is about 30%-40%

And the weight of avocados is 8 ounce

So, the weight of seed and skin is about 30% of 8 to 40% of 8

i.e 2.4 ounce to 3.2 ounce

Then the edible fruit is about 60% to 70%

i.e 60% of 8 to 70% of 8

Thus edible fruit of avocados = 4.8 ounce to 5.6 ounce   Answer

a man drives for awhile at 45 mph. Realizing he is late ,he increases his speed to 60 mph and completes his 405 mile trip in 8 h
Harlamova29_29 [7]
By definition, we have the following equation:
 d = v * t
 Where,
 d = Distance
 v = rate
 t = time

 The total distance traveled will be:
 45t + 60 (8 - t) = 405
 Solving for the time we have:
 t = 5 s
 Answer:
 
he drives at 45 mph for 5 s

A triangle has two sides of length 3 and 3. What value could the length of thethird side be? Check all that apply.A. 6B. 12C. 5D
Bumek [7]

To find out the length of the third segments of the triangle, we can use this formula.

\begin{gathered} a^2=b^2+c^2 \\ a^2=3^2+3^2 \\ a^2=9+9 \\ a^2=18 \\ a=4.25 \end{gathered}

The, third length is very close to the 4. thus, the option (E) is correct.
