Since your scale is 1ft:1.26cm, a 30-ft tall school would need to have a 

 cm model. Dividing this by how tall each toothpick is, you'll get:
 ANSWER:
ANSWER: The model would be 6 toothpicks tall.
To find out how many cotton swabs you'll need, we just divide 37.8 by how tall each swab is:
 ANSWER:
ANSWER: The model would be 5 cotton swabs tall.
 
        
        
        
Using the image I gave you, you don't need to solve for x.
So tan is opposite/adjacent
sin: opposite/hypotenuse
cos: adjacent/hypotenuse
Take theta and do: adjacent/hypotenuse which is cosine
cos theta = adjacent/hypotenuse
cos theta = 1.5/9
inverse cos = 1.5/9 and the answer is: 80.4 degrees
 
        
        
        
Answer:
The total cost of 4 burgers and 6 hot dog would be $25.00
Step-by-step explanation:
First, identify what you know: 
1) One burger costs $3.25
2) One hot dog costs $2.00
3) We are given the formula 3.25b + 2h
Thus, all we need to do is plug in our values! 
3.25(4) + 2(6) = x
13 + 12 = x
x = $25
Hope this helps! :)
