Tomb trees are standing side-by-side in the sunlight one is 50 feet tall and the other is 20 feet tall if the taller tree cast a

8090 [49]

Answer: Length of shorter tree = 7.2 feet .

Step-by-step explanation:

Given : Height of two trees as 50 feet and 20 feet.

At same time the angle made by sun rays would be same for both trees.

Both trees are vertical to the ground making right angle so triangles made by both triangles must be similar.

Corresponding sides of similar triangles are proportional.

So $\dfrac{\text{length of the shadow of the shorter tree}}{\text{height of shorter tree}}=\dfrac{\text{length of the shadow of the bigger tree}}{\text{height of bigger tree}}\\\\=\dfrac{\text{length of the shadow of the shorter tree}}{20}=\dfrac{18}{50}\\\\\Rightarrow\ \text{length of the shadow of the shorter tree}=\dfrac{18}{50}\times20\\\\\Rightarrow\ \text{length of the shadow of the shorter tree} = 7.2$

So, Length of shorter tree = 7.2 feet .

Answer:

30 small chairs and 24 large chairs

Step-by-step explanation:

Let x and y represent the numbers of small chairs and large chairs built in a day. Then the relations for using available time are ...

20x +50y = 30×60

60x +90y = 66×60

Removing common factors, these can be written in standard form as ...

2x +5y = 180

2x +3y = 132

Subtracting the second equation from the first gives ...

2y = 48

y = 24 . . . . . divide by 2

Using the first equation to find x, we have ...

2x +5(24) = 180

2x = 60 . . . . . . . . . . subtract 120

x = 30 . . . . . . . . divide by 2

The company can build 30 small chairs and 24 large chairs in a day.
