The concept useful in finding the answer to this item is ratio and proportion, the ratio of the height of your friend with the shadow casted should be proportional to the height of the rock with the length of the shadow it cast. That is,
5.5 ft / 18 ft = x ft/ 209.5 ft
The value of x from the equation above is 64 ft.
Answer: x=8/27 +1/27 •log(downward 5)(6)
A whole number is a fraction with a denominator of one
Answer with Step-by-step explanation:
We are given that:
tanA = 0.45
tanA= 
= 
⇒ =0.45
⇒ 
=
⇒ =
⇒ AC= 20
Hence, by pythagoras theorem
AB²=AC²+BC²
AB²=20²+9²
AB²=481
⇒ AB=21.9 units
Hence, the approximate length of AB is:
22 units
You need to add 1 3/4, 2 1/3, and 2 3/4.
But before you do that you need to make them decimals.
Add 1.75, 2.33, and 2.75
Equals 6.83
Then subtract it by 20.00
Equals 13.17
Then you make that a decimal
13 17/100
