What is the cube root of 216x18?

Vikentia [17]

Answer:

<u>The correct answer is 15.72 or 6 ∛18</u>

Step-by-step explanation:

Let's calculate the cube root of 216 * 18

∛(216 * 18)

216 = 8 * 27

8 = 2³; 27 = 3³

18 = 9 * 2 or 3² * 2

∛(8 * 27 * 18)

Simplifying:

∛(2³ * 3³ * 3² * 2)

2 * 3 ∛(3² * 2

bazaltina [42]

The percentage of the people surveyed that were satisfied with the car is 45%.

<u>Given the following data:</u>

Total population = 1,600 people

Number of car owner = 720 people.

To determine the percentage of the people surveyed that were satisfied with the car:

<h3>How to solve for a percentage.</h3>

In this exercise, you're required to calculate the percentage of the total population in this survey that would by a particular type of car again because they were satisfied with it. Thus, we would solve for the percentage as follows;

$Percent = \frac{Satisfied\;persons}{Total\; population} \times 100$

Substituting the given parameters into the formula, we have;

$Percent = \frac{720}{1600} \times 100\\\\Percent = 0.45 \times 100$

Percent = 45%
