20% off means you pay 80% of the price so you multiply by 0.8, and 7% tax means you multiply by 1.07
Resulting cost = 18.99*0.8*1.07 = 16.26
Hope this helps let me know if im wrong!
 
        
                    
             
        
        
        
Answer:
D. <b ≅ <g
Step-by-step explanation:
Given that lines p and q are parallel to each other, therefore the following can be concluded:
✔️<f ≅ <h, this is because they are both Vertical angles.
✔️<d and <h are supplematry, this is because they are same side consecutive interior angles. Consecutive angles are supplematry.
✔️<a and <b are supplematry, this is because they are linear pair angles.
✔️<b cannot be congruent to <g. They are not corresponding angles, nor are they alternate interior angles.
 
        
             
        
        
        
SA: 2pi (r^2)+2pi(r)(h)
In order to find radius (r) of the base you must divide 10 by pi then find the square root of the result
√(10/pi)=r: 1.784cm
h: a) 8.0cm
 b) 6.5cm
 c) 9.4cm
2pi (3.183)+2pi(1.784)(8)=109.673cm^2
2pi (3.183)+2pi(1.784)(6.5)=92.859cm^2
2pi (3.183)+2pi(1.784)(9.4)=125.366cm^2

Answer:
Step-by-step explanation:  
It can be convenient to compute the length of the hypotenuse of this triangle (AC). The Pythagorean theorem tells you ...
    AC^2 = AB^2 + CB^2
    AC^2 = 4^2 + 3^2 = 16 + 9 = 25
    AC = √25 = 5  
The altitude divides ∆ABC into similar triangles ∆AHB and ∆BHC. The scale factor for ∆AHB is ...
   scale factor ∆ABC to ∆AHB = AB/AC = 4/5 = 0.8  
And the scale factor to ∆BHC is ...  
   scale factor ∆ABC to ∆BHC = BC/AC = 3/5 = 0.6  
Then the side AH is 0.8·AB = 0.8·4 = 3.2
And the side CH is 0.6·BC = 0.6·3 = 1.8  
These two side lengths should add to the length AC = 5, and they do.  
The remaining side BH can be found from either scale factor:    
   BH = AB·0.6 = BC·0.8 = 4·0.6 = 3·0.8 = 2.4
_____  
The sides of interest are ...  
   AH = 3.2
   CH = 1.8
   BH = 2.4
