3^(-2) = 1/(3^2) = 1/(3*3) = 1/9
The rule used here is x^(-y) = 1/(x^y) to make the exponent positive.
3^2 turns into 3*3 because the exponent 2 tells us how many copies of the base '3' to multiply out.

Answer: 5/8 inch represents 1 mile
Step-by-step explanation:
to get 1, multiply 4/5 by its reciprocal, 5/4
Then multiply 1/2 by 5/4
1/2 × 5/4 = 5/8
The external angle at the intersection of two secants is half the difference of the intercepted arcs. That is
∠E = (1/2)(4x° -2x°) = x°
The given measure of arc AB tells you
... 4x° = 56°
... x° = 14°
The appropriate choice is ...
... B. 14°
If you sum the amounts of each ingredient, you have a total of
So, the whole cocktail is 50ml. Of these, 10 are coconut milk. So, the ratio coconut : total is
