Answer:

BD = 6

Step-by-step explanation:

Theorem:  The altitude to the hypotenuse of a right triangle is the mean proportional between the segments of the hypotenuse.

So, \frac{4}{BD} = \frac{BD}{9}

BD^{2}  = 36

BD = 6

See how easy that is IF you know the theorem.

nika2105 [10]

Answer:

A. 48 Km.

B. 62.5 miles.

Step-by-step explanation:

From the diagram given above, the following data were obtained:

50 miles = 80 Km

A. Converting 30 miles to kilometres.

50 miles = 80 Km

Therefore,

30 miles = 30 miles × 80 Km / 50 miles

30 miles = 48 Km

Thus, 30 miles is equivalent to 48 Km.

B. Converting 100 km to miles.

80 Km = 50 miles

Therefore,

100 Km = 100 Km × 50 miles / 80 Km

100 Km = 62.5 miles

Thus, 100 Km is equivalent to 62.5 miles.
