The drawing at the right shows a person, 5 feet tall, casting a shadow 3 feet long.
The tree is casting a shadow 15 feet long.
How tall is the tree?

25 feet tall

Step-by-step explanation:

First, let's take a look at the person. If they are 5 feet tall and cast a shadow of 3 feet, we can easily convert this into a proportion: 5 feet tall: 3 feet shadow.

Continuing with this method, we can convert the tree into a proportion: x feet tall: 15 feet shadow.

So, 5:3=x:15. Mathematically, think of it as 5/3=x/15.

To find x, you will need to multiply 15 to both sides, or perform cross multiplication.  (5/3)(15)=(x/15)(15). This will equal 25. The tree is 25 feet tall.

step-by-step explanation:

most likely the answer is a.

alice wins if a total of 5 is rolled. finn wins if a total of 9 is rolled.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
