Answer:
Total price of the album including tax is $10.08
Step-by-step explanation:
Sales price without discount and tax = $12
% discount = 20%
Sales price with discount = 12 - (20/100 × 12) = 12 - 2.4 = $9.6
% sales tax = 5%
Tax = 5/100 × 9.6 = $0.48
Total price of the album including tax = $9.6 + $0.48 = $10.08
Step-by-step explanation:
The standard equation of a circle is 
Center = (h, k)
#1
Center = (0,2)
h = 0
k = 2
r = 5


#2
Center = (-4,-5)
h = -4
k = -5
r = 



#3
Center =(-1,3)
h = -1
k = 3
r = 8



#4
Center: (9,0)
h = 9
k = 0
r = 


Dividing fractions is equivalent to taking the reciprocal of the second and multiplying them. In this case, we have 1/2*8/5=8/10=4/5.
72 and 50 are the answer for 12 times 6 and 10 times 5
