Ratio is just a single fraction. Whereas proportion is a ratio between 2 fractions. The basic difference is Ratio is always with respect to some large quantities or superior quantities, whereas proportion is between same kind of quantities.
Answer:
The correct answer is B. ![\sqrt[9]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B9%5D%7B3%7D)
Step-by-step explanation:
The root of a number can be expressed as the number raised to the power whose exponent is a fractional number. The exponent number will be the inverse of the root index.
In this case, three to the two thirds power all raised to the one sixth power is expressed as:

Power of a Power Property: This property states that the power of a power can be found by multiplying the exponents.
So, we multiply the exponents:

The expression would be:

which as a radical expression is:
![\sqrt[9]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B9%5D%7B3%7D)
The four options are expressed as:
a) ![\sqrt[6]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B6%5D%7B3%7D)
b) ![\sqrt[9]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B9%5D%7B3%7D)
c) ![\sqrt[18]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B18%5D%7B3%7D)
d) ![\sqrt[6]{3^3}](https://tex.z-dn.net/?f=%5Csqrt%5B6%5D%7B3%5E3%7D)
The correct answer is B.
Answer:
None
Step-by-step explanation:
Distribute the 2 to the parentheses:
2(2x + 3) = 4x + 7
4x + 6 = 4x + 7
Subtract 4x from both sides:
6 = 7
6
7
This not true, since 6 can never be equal to 7.
This means there are no solutions
Step-by-step explanation:
Vicky Bought:
Strawberries $3.50
Carrots $2.25
Flowers $9.95
Subtotal $3.50 + $2.25 + $9.95
= $15.70
5% Sales Tax (5% of Subtotal) = 5/100 x $15.70
= $0.785 (will not round off here as it is not the final answer.)
Total = Subtotal + 5% Sales Tax
= $15.70 + $0.785
= $16.485
= $16.49 (rounded off to nearest cent)
