Answer:

<h2>Amplitude</h2>

Step-by-step explanation:

Basically, when we talk about sound waves, we have certain properties to analyse, where each of them is responsible for a specific effect.

Specifically, in this case, louder sound belongs to bigger amplitude, because the amplitude can be defined as how far is a string from its equilibrium point. In case of a tuning fork, the bigger amplitudes represent a higher movement when it vibrates, which gives louder sounds.

Therefore, the right answer is amplitude.

|x| + 4 > 7 plz help and hurry

Talja [164]

Answer:

The solution is $(-\infty,-3)\cup(3,\infty)$ .

Step-by-step explanation:

Given:

The inequality given is:

$|x|+4>7$

In order to simplify for 'x', we first isolate 'x' on one side.

Adding -4 on both sides, we get:

$|x|+4-4>7-4\\\\|x|>3$

Now, $|x|$ is an absolute value function which is defined as:

$|x|=\left \{ {{-x}\ \ x$

Therefore, the given inequality can be rewritten as:

$-x > 3\\x$ and $x > 3$

Therefore, the solution is $(-\infty,-3)\cup(3,\infty)$ .

Caeli is designing a flag that will be in the shape of a rectangle. She has 10 square feet of fabric to use, and she wants the h

vampirchik [111]

Answer:

<u>If Caeli will use all of the fabric she has, the base of the flag should be of 4 feet.</u>

Step-by-step explanation:

1. Let's review the information provided to answer the question correctly:

Area of the fabric Caeli has and want to use and design = 10 square feet

Height of the rectangle of the rectangle shape = 2.5 feet

2. What is the base of the flag if she will use all of the fabric she has?

Area of the shape of the rectangle = Height of the flag * Base of the flag

Replacing with the real values:

10 square feet = 2.5 feet * Base of the flag

10 square feet/2.5 feet = Base of the flag

<u>Base of the flag = 4 feet</u>

<u>If Caeli will use all of the fabric she has, the base of the flag should be of 4 feet.</u>
