Which of the following is the most appropriate unit to describe the rate at which people are entering a theme park?
ad-work [718]

The <u><em>correct answer</em></u> is:

d) People per hour, because the dependent quantity is the people

Explanation:

In this situation, the two quantities are people and hours. These are the two things in this problem we can count or measure.

The independent variable is the one that causes a change, while the dependent variable is the one that <em>gets</em> changed. In this situation, the number of people change every hour; this means the number of people <em>gets</em> changed, which makes it the dependent variable. This means that the independent variable must be time.

Since people is dependent and time is independent, "people per hour" would be the best form of this statement.

Three times the sum of a number and 15 is 24
allsm [11]

Answer:

\huge\boxed{\sf x = -7}

Step-by-step explanation:

<em>Let the number be x </em>

So,

=> The sum of number and 15 is x + 15

=> Three times will be 3(x+15)

<u>Given that</u> it equals 24

<u>So, the given condition is:</u>

3(x+15) = 24

<em>Resolving Parenthesis</em>

3x + 45 = 24

<em>Subtracting 45 to both sides</em>

3x = 24 - 45

3x = -21

<em>Dividing both sides by 3</em>

x = -7

X squared +10x-24<br><img src="https://tex.z-dn.net/?f=x%20%7B%3F%7D%5E%7B2%7D%20%20%2B%2010x%20-%2024" id="TexFormula1" title="

Solve for x using factorizing:
x^2 + 10 x - 24 = 0

The left hand side factors into a product with two terms:
(x - 2) (x + 12) = 0

Split into two equations:
x - 2 = 0 or x + 12 = 0

Add 2 to both sides:
x = 2 or x + 12 = 0
Subtract 12 from both sides:
Answer:  x = 2 or x = -12
