If a tree 41.8 feet tall casts a shadow that is 27 feet long, find the height of a tree casting a shadow that is 18.3 feet long

Neko [114]

Answer:

28.3 feet

Step-by-step explanation:

Given a tree 41.8 feet tall casts a shadow that is 27 feet long

So the Tangent of the angle of the sahdow remains the same for the both trees.

We know that $Tanx=\frac{height of the tree}{length of the shadow}$

$\frac{height of the tree1}{length of the shadow1} = \frac{height of the tree2}{length of the shadow2}$

$\frac{41.8}{27} =\frac{x}{18.3}$

$x=\frac{41.8}{27}\times18.3 =28.3$

Therefore the height of the tree is 28.3 feet

An amphitheater charges $74 for each seat in Section A, $59 for each seat in Section B, and $28 for each lawn seat. There are th

Ivenika [448]

Answer:

Step-by-step explanation:

let x be the number of seats in A,

y be the number of seats in B, and

z be the number of lawn seats.

y=3x

the total number of seats is given by

(x+y+z)=13000

put y=3x

(x+3x+z)=13000

(4x+z)=13000------1

also

(4x+z)13000=503000----2

hence the systems of equation is

(4x+z)=13000------1

(4x+z)13000=503000----2

Complete the solution of the equation. Find the value of y when x equals 4. -7x + y = -22

xz_007 [3.2K]

-7x + y = -22

-7*4 + y = -22

y = -22 + 28

y = 6
