Simplify 161/4 x 2⁻³ x 30

The calculated answer is $\frac{1}{4}$. However, this is not among the given options (A. 4, B. 8, C. 16, D. 32). Assuming there might be a typo in the question and $2^{-3}$ was intended to be $2^3$, let's re-evaluate:

Based on this assumption, the answer would be 16.

The most likely intended answer from the options, assuming a common typo, is C.

If $x$ varies directly as the cube root of $y$, then $x = k \sqrt[3]{y}$, where $k$ is the constant of proportionality.

The final answer is $\boxed{\text{A. } 4.5}$.

The simple interest formula is $I = PRT$.
Given:
$I = N6,525.00$
$P = N52,200.00$
$T = 2\frac{1}{2} \text{ years} = 2.5 \text{ years}$

To express as a percentage, multiply by 100:

The final answer is $\boxed{\text{A. } 5.0\%}$.

The number is 0.07552. The second decimal place is 7.

The digit after 7 is 5.

Since the digit (5) is 5 or greater, round up the second decimal place.
Rounding 7 up gives 8.

So, 0.07552 rounded to two decimal places is 0.08.

The final answer is $\boxed{\text{D. } 0.08}$.

To simplify, multiply the numerator and denominator by 10000:

The final answer is $\boxed{\text{B. } 1.00 \times 10^2}$.

Divide 143 by 5 repeatedly and record the remainders:
$143 \div 5 = 28$ remainder 3
$28 \div 5 = 5$ remainder 3
$5 \div 5 = 1$ remainder 0
$1 \div 5 = 0$ remainder 1
Reading the remainders from bottom to top gives $1033_5$.

The final answer is $\boxed{\text{B. } 1033_5}$.
