Answer:

2/3

Step-by-step explanation:

1/2 dresses = 36x1/2 = 18

18 dresses in 3/4 hr. ==> 1/4hr ==> 18/3 = 6

1hr ==> 6x4 = 24

fraction = 24/36 = 2/3

((5x-16) cubed -4)cubed = 216,000X = _________
Lemur [1.5K]

Given the equation:

((5x-16)^3-4)^3=216000

Applying the exponent laws:

\begin{gathered} \sqrt[3]{((5x-16)^3-4)^3}=\sqrt[3]{216000} \\ (5x-16)^3-4=60 \end{gathered}

Simplify:

\begin{gathered} (5x-16)^3-4+4=60+4 \\ (5x-16)^3=64 \end{gathered}

Applying the exponent laws:

\begin{gathered} \sqrt[3]{(5x-16)^3}=\sqrt[3]{64} \\ Simplify \\ 5x-16=4 \\ 5x-16+16=4+16 \\ 5x=20 \\ \frac{5x}{5}=\frac{20}{5} \\ x=4 \end{gathered}

Answer: x = 4

Appended below is the code for Selection Sort. You really do not have to understand the details of the code. If this algorithm t
kramer

Answer:

12 seconds.

Step-by-step explanation:

Let t represent time taken by code to sort an array of 24 elements.

We have been given that an algorithm takes 4 seconds to sort an array of 8 elements. We are asked to find the time it will take for same code to sort an array of 24 elements.

We will use proportions to solve our given problem.    

\frac{\text{Time}}{\text{Array of elements}}=\frac{4}{8}

\frac{t}{24}=\frac{4}{8}

\frac{t}{24}\cdot 24=\frac{4}{8}\cdot 24

t=\frac{4}{1}\cdot 3

t=12

Therefore, it will take 12 seconds for the same code to sort an array of 24 elements.
