8. In the figure, ADC is a straight line.
dlinn [17]

Answer:

a). ΔABC ~ ΔBDC

b). m(BD) = 6 units

Step-by-step explanation:

If ΔABC ~ ΔBDC,

a). Ratio of the corresponding sides of both the triangles will be equal.

\frac{AB}{BD}=\frac{BC}{DC}=\frac{AC}{BC}

\frac{BC}{DC}=\frac{AC}{BC}

\frac{12}{9}=\frac{7+9}{12}

\frac{4}{3}=\frac{4}{3}

Since Ratio of the corresponding sides are same, therefore, both the triangles are similar.

b). \frac{AB}{BD}=\frac{BC}{DC}

\frac{8}{BD}=\frac{12}{9}

BD = \frac{9\times 8}{12}

BD = 6

Megan drove from her house to work at an average speed of 45 miles per hour. The drive took her
-Dominant- [34]

Answer:

30

Step-by-step explanation:

Since the question says that it took her 45 minutes per hour, you can use that to find the distance of the route she took.  

45 miles: 60 minutes  

15 miles: 20 minutes ----------------cross multiply (20x45 and then divide by 60)  

Therefore, if she is going to use the same route in reverse, the distance would be 15 miles.  

Use the formula for speed:  

speed= distance/time  

= 15/0.5 ---------- 0.5 hours is the same as 30 minutes  

= 30
