Given the diagram below with line DE║ line AC. Find BC.
Karolina [17]

Answer:

13.5

Step-by-step explanation:

In triangle ABC, DE || AC

Therefore by basic proportionality theorem:

\frac{BD}{DA} = \frac {BE}{EC} \\\\\therefore  \frac{4}{8} = \frac {BE}{9} \\\\\therefore  \frac{1}{2} = \frac {BE}{9} \\\\\therefore  BE = \frac{9}{2} \\\\\therefore BE = 4.5\\\because BC = BE + EC \\\therefore BC = 4.5 + 9\\\huge \red {\boxed {\therefore BC = 13.5}} \\

<h3>Answer: Perpendicular</h3>

The slopes -2/3 and 3/2 multiply to -1, which is sufficient info that the lines are perpendicular. Perpendicular slopes always multiply to -1 assuming neither line is vertical nor horizontal.

Note how -2/3 is the negative reciprocal of 3/2, and vice versa.

In hopes of encouraging healthier snacks at school, Leah brought in a tray of carrot sticks
aleksandr82 [10.1K]

Answer:

40 %  of the snacks were carrot sticks.

Step-by-step explanation:

Total number of carrot sticks in lunch = 18

Total number of apple slices in lunch = 27

So, Total Snacks in the Lunch = Carrot Sticks + Apple Slices

                                                   = 18 +  27 = 45

Now, \textrm{Percentage of Carrot Sticks}  = \frac{\textrm{The number of Carrot sticks in lunch}}{\textrm{Total snacks in the lunch}}  \times 100

= \frac{18}{45}  \times100 = 40

⇒Percentage of Carrot Sticks = 40%

Hence, 40 %  of the snacks were carrot sticks.
