Answer:
from this table we can tell Y is always 10 times bigger then X so we just have to multiply it again by ten so the answers are
300
500
700
 
        
                    
             
        
        
        
Answer:
A.  
General Formulas and Concepts:
<u>Trigonometry</u>
- [Right Triangles Only] SOHCAHTOA  
- [Right Triangles Only] sinθ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
sin 30°
<u>Step 2: Solve</u>
Since sin is opposite over hypotenuse, we need to find the length of the opposite leg of the angle and the length of the hypotenuse.
Given the triangle and it's values, the opposite leg to the 30° angle is 1 and the hypotenuse is 2.
Substituting it into sin, we have:
sin 30° = 1/2 = 0.5
∴ our answer is A.

Answer:
The square cake is has a larger area by about 40.73 square inches
Step-by-step explanation:
Find the area of the top of each cake.
The square cake has an area of 81 sq inches,   ( length x width = Area, the 
                                                                                     length is 9)
The round cake has an area of 16π, which is about 50.27 square inches
   (A = πr², here r is 4, radius is half the diameter)
81 - 16π =  81 - 50.27 =  40.73 square inches
