Answer:
$21.80
Step-by-step explanation:
50% of 38 is 19. 10% of 38 is 3.8. Add these together to get 21.8. This equates to $21.80.
 
        
             
        
        
        
Answer:
D.
Step-by-step explanation:
Choices A., B., and C. are always true.
Choice D. is true only for rectangles with congruent sides, which are squares.

Answer:
<em>201.06 sq. ft.</em>
Step-by-step explanation:
Area of a circle is found by using the equation:
 
Radius = 1/2 (diameter) = 1/2 (16) = 8
So plug in:

A = 64
A = 201.06193 
Rounded A= 201. 06
 
        
             
        
        
        
Answer:
19 girls
Step-by-step explanation:
Since there are 3 more girls than boys, 35-3=32
32/2=16
Now add back the 3
16+3=19
 
        
                    
             
        
        
        
Angles formed by the segment  in the triangles ΔWXZ, and ΔXYZ, are equal and the given corresponding sides are proportional.
 in the triangles ΔWXZ, and ΔXYZ, are equal and the given corresponding sides are proportional.
- The option that best completes the proof showing that ΔWXZ ~ ΔXYZ is; <u>16 over 12 equals 12 over 9</u>
Reasons:
The proof showing that ΔWXZ ~ ΔXYZ is presented as follows;
Segment  is perpendicular to segment
 is perpendicular to segment 
∠WZX and ∠XZY are right angles by definition of  perpendicular to
  perpendicular to 
∠WZX in ΔWXZ = ∠XZY in ΔXYZ = 90° (definition)


Therefore;
 , which gives, , which gives, 
Given that two sides of ΔWXZ are proportional to two sides of ΔXYZ, and 
that the included angles between the two sides, ∠WZX and ∠XZY are 
congruent, the two triangles, ΔWXZ and ΔXYZ are similar by Side-Angle-
Side, SAS, similarity postulate.
The option that best completes the proof is therefore;
 which is; <u>16 over 12 equals 12 over 9</u> which is; <u>16 over 12 equals 12 over 9</u>
