100%=9.99
×%=6.75
9.99x=100×6.75
9.99X=675
X=675/9.99
67.567% or 67.57
you could also say:
6.75/9.99=0.67567
0.67567×100=67.57%
so the markup is 100%-67.57%=32.43%
32.43%off
Answer:
B. a = rⁿ
C. a¹/ⁿ = r
Step-by-step explanation:
ⁿ√a = r
The above expression can be simplified as follow:
1. ⁿ√a = r
Recall:
ⁿ√a = a¹/ⁿ
Therefore,
a¹/ⁿ = r
2. ⁿ√a = r
Take the n square of both side
(ⁿ√a)ⁿ = rⁿ
(a¹/ⁿ)ⁿ = rⁿ
a = rⁿ
Answer:
The number of solutions of an equation is dependent upon the total number of variables contained in it. Thus, the system of the equation has two or more equations containing two or more variables. It can be any combination such as 1. 2 equations in 3 variables 2. 6 equations in 4 variables, and so on Depending on the number of equations and variables, there are three types of solutions to an equation. They are 1. Unique Solution (One solution) 2. No solution 3. Infinite Solutions (Many solutions) The term “infinite” represents limitless or unboundedness. It is denoted by the letter ” ∞ “
