Answer:
B C D
Step-by-step explanation:
ratio of discount (d) over original price(P)
<em>d</em><em>/</em><em>P</em>
B. (28100-24750)÷28100= 11.92%
C. 8/58 = 13.79%
D. (1.99-1.75)÷ 1.99= 12.06%
while A. is 16.08%
E. is 19.05%
Answer:
Step-by-step explanation:
let the national average be x
11/100 * x = 11x/100
25.47 - x = 11x/100
100(25.47-x) = 11x
2547 - 100x = 11x
2547 = 11x + 100x
2547 = 111x
x = 2547/111
x = 22.945945945946
22.95
Answer:
to complete the square, you add (b/2)^2 on both side. in this case, b is -6, half of -6 is -3, -3 squared is 9, so:
x^2-6x+9=-13+9
(x-3)^2=-4
This quadratic equation have unreal solutions
