Answer:

A rational number is a number that can be express as the ratio of two integers. ... However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number. Likewise, any integer can be expressed as the ratio of two integers, thus all integers are rational.

A six feet-tall person is standing next to a flag pole.The person is casting a shadow 1 1/2 feet in length,while the flagpoleis

Vlad1618 [11]

Answer:

20 feet

Step-by-step explanation:

Consider the given pictorial representation below,

The Height of the Pole =|AB|

The Height of the Person =|DE|

Shadow cast by the Pole =|AC|

Shadow cast by the Person =|EC|

Triangles ABC and DEC are similar triangles therefore,

$\frac{|DE|}{|AB|} =\frac{|EC|}{|AC|}$

$\frac{6}{x} =\frac{1.5}{5}$

Cross multiplying

x X 1.5 = 6 X 5

x=30/1.5 =20 feet

Height of the flag pole = 20 feet

If triangle abc is similar to triangle def with ab=9, bc=11, and ac=16, then which of the following is closest to the ratio of d

aleksandr82 [10.1K]

Answer:

$\frac{de}{df}=\frac{9}{16}$ or $\frac{de}{df}=0.5625$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional

so

In this problem

Triangle abc is similar to Triangle def

therefore

$\frac{de}{df}=\frac{ab}{ac}$

substitute the given values

$\frac{de}{df}=\frac{9}{16}$
