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

A store advertises 15% off an item that regularly sells $300.what is the sale price off the item?

Komok [63]

The original price of the item is said to be 100 dollars.
Now, it offers 15% discount. Let's solve for the dicounted price.
=> 15% = 0.15
Solution:
=> 300 * .15
=> 45 dollars
=> 300 dollars - 45
=> 255 dollars

I already made an attempt at this question and I would just like to check my answer z = ?

Salsk061 [2.6K]

So we have the equation:

$\frac{z+9}{4}=2.1$

Then we need to multiply by 4 on both sides to get rid of the denominator on the left:

$z+9=8.4$

Then we subtract 9 on both sides to solve for z:

$z=-0.6$

Therefore the answer is z = -0.6.
