Shadow
-----------
height
28 8
------ = ------------
tree 5
Using cross products
28*5 = 8 * tree
140 = 8 * tree
divide each side by 8
140/8 = 8 *tree/ 8
17.5 = tree
2x=44
X= 22
Half of 88 is 44
State whether the data described below are discrete or continuous, and explain why.
the exact distances in centimeters between the chairs in a college classroom
Answer: The described data is continuous variable because the exact distances in centimeters between the chairs in a college classroom can take any value within a measurement scale.

Answer:
one cup of coffee costs $2, while one bottle of water costs $1
Step-by-step explanation:
We can represent this using two equations:
- Variable <em>x </em>represents cups of coffee, and variable <em>y</em> represents bottles of water.
5<em>x</em> + 2<em>y</em> = 12
4<em>x</em> + 7<em>y</em> = 15
Your answer for the value of <em>x</em> and <em>y</em> should be
<em>x</em> = 2
<em>y</em> = 1
Therefore, one cup of coffee costs $2, while one bottle of water costs $1.
