1 / 10 is the easiest answer. Remember ratios are just percentages. It could also be 2/20, 3/30, as long as it is 10%.

Step-by-step explanation:
This answer is correct because, adding 0.15x (or 15%) to the total amount is the same as multiplying the cost by 1.15. This is because, the 1 that is added to 0.15 represents the total, since we are just multiplying instead of adding to it.
Hope this helps! :D

Answer:
3
Step-by-step explanation:
The f^-1 notation indicates you need to find the inverse of the function
y=2x+1
x=2y+1
Exchange the x & y variables. Note this is what accomplishes that reflection across the line y = x
7=2y+1
-2y=1-7
-2y=-6
Divide both side of the equation by -2
negative divide negative is positive so
y=3
Answer:
≈ 153.86
Step-by-step explanation:
Area of a circle's formula is: A = πr² π in this would be approximately 3.14
using this formula and the given radius, we can plug it into the formula
A = (3.14)(7)² --> A= (3.14)(49) ≈ 153.86
