A lamp post with a height of 12 ft casts a shadow of 6 ft. A fire hydrant near it casts a shadow that is 1.5 ft long. How tall i

alex41 [277]

Answer:

3ft

Step-by-step explanation:

We are given that

Height of lamp, h=12ft

Height of shadow, l=6ft

Height of shadow of hydrant, l'=1.5ft

Let height of hydrant=h'

We have to find the height of fire hydrant.

All right triangles are similar

When two triangles are similar then, the ratio of their corresponding sides are equal.

Using the property

$\frac{h}{h'}=\frac{l}{l'}$

$\frac{12}{h'}=\frac{6}{1.5}$

$h'=\frac{12\times 1.5}{6}$

$h'=3$ ft

Hence, the height of fire hydrant=3 ft

Which fraction and equivalent decimal correctly shows the ratio of shaded circles to all circles?

sergeinik [125]

Shaded circles = 4
Total circles = 12

$\frac{shaded~circles}{total~circles}$ = $\frac{4}{12}$

$\frac{4}{12}$ as a simplified expression = $\frac{2}{6}$
We can simplify it even more = $\frac{1}{3}$

Fraction = $\frac{1}{3}$

Equivalent decimal = 1 ÷ 3 = 0.33
