Answer:
The first store
Step-by-step explanation:
3sweaters->$44.99
4sweaters->x
x=4×44.99/3 x=$59.98
3sweaters->$52.00
4sweaters->x
x=4×52/3 x=$69.33
first store<second store
59.98<69.33
 
        
             
        
        
        
Answer:
16= (x-4)^2 +(y+9)^2
Step-by-step explanation:
hey! The formula for the equation of a circle is r^2= (x-h)^2 + (y-k)^2
r= the radius (in your case you have the diameter so you do not need to square it)
(h,k)= is the center coordinates, so your center coordinate would be (4, -9). You now have your h (h=4) and your k (k=-9) so you can plug it in the formula! :)

we know that
Using the original score as the basis
If Misha increased her test score from  % to
% to  %
%
then
the increase variation is equal to
 %-
%- %=
%= %
%
to find the approximate percent increase of Misha's test score we apply a rule of three
if  %--------------> represents
%--------------> represents  %
%
 %----------------->x
%----------------->x

 %
%
therefore
the answer is
the approximate percent increase of Misha's test score is  %
%
 
        
                    
             
        
        
        
N= the # of books
So you're trying to find n and you have the cost for the printed books, which is 15,000, so you would set up your equation like this:
15,000=500+10n 
Subtract 500 from each side
14850=10n 
Divide by 10
n=1,485 books are printed
