Answer:
The dimension of the rectangular pool is
Step-by-step explanation:
Given : A rectangular swimming pool is three times as long as it is wide. If the perimeter of the soccer field is 300 yards.
To find : What are the dimensions?
Solution :
Let the width of the rectangular pool be 'x'.
A rectangular swimming pool is three times as long as it is wide.
The length of the pool be '3x'
The perimeter of the rectangular swimming pool is
The perimeter of the soccer field is 300 yards.
Substitute the value in the formula,
The width of the pool is x=37.5 unit
The length of the pool is
Therefore, The dimension of the rectangular pool is
Answer:
Q-12 The vertical length of the top part of elevator to ground is 0.8484 meters .
Q -14 The glide runway path is 24,752.47 feet .
Step-by-step explanation:
Q - 12
Given as :
The diagonal length of the elevator = e = 1.2 meters
The vertical length of the top part of elevator to ground = x meters
The angle made by elevator with ground = Ф = 45°
<u>Now, According to figure</u>
Sin angle =
Or, Sin Ф =
Or, Sin 45° =
Or, 0.707 × 1.2 meters = x
∴ x = 0.8484 meters
So, The vertical length of the top part of elevator to ground = x = 0.8484 meters
Hence,The vertical length of the top part of elevator to ground is 0.8484 meters . Answer
Q-14
Given as:
The altitude of decent of plane = H = 10,000 feet
The angle of descend = Ф = 22°
Let the glide runway path = y feet
<u>Now, According to question</u>
Tan angle =
Or, Tan Ф =
Or, Tan 22° =
Or, 0.4040 =
Or, y =
∴ y = 24,752.47
So,The glide runway path = y = 24,752.47 feet
Hence, The glide runway path is 24,752.47 feet . Answer
