ft
Step-by-step explanation:
We know that the height of the object and the height of the shadow it casts are proportional. Therefore, if we let the length of the tree be 
, we can set up the following proportion to solve for it:
Solving for , we get:
(Cross-Products Property)
(Simplify)
(Divide both sides of the equation by 8 to get rid of 's coefficient)
(Simplify)
Therefore, the tree is ft tall. Hope this helps!

Answer: 18 quarts for Part a
9 gallons for part b
Step-by-step explanation:
We know that 30.1111... is a rational number because it ends in repeating decimals. We can show this by writing the number as a fraction using algebra.
x = 30.1111....
10x = 301.1111....
Subtract both sides by x
10x - x = 301.1111.... - 30.1111...
9x = 271
x = 271/9
The number can be rewritten as 271/9, which you can verify is the same number by checking on a calculator.
