The midpoint of the range of frequencies given is:
midpoint = (82.4 + 659.2) / 2 = 370.8 Hertz
Then the difference from midpoint to the other end is:
370.8 - 83.4 = 288.4 Hertz
Therefore the inequality formula is
|f - 370.8| <= 288.4

The area of a square bedroom is 144 square feet. what is the length of one wall?
The length of one wall of the bedroom is 12 feet, which is the square root of the room's area of 144 square feet
The area of a square is calculated by squaring the length of one of its sides, so if the area of a square bedroom is 144 square feet, the length of one side can be found by taking the square root of the area. Therefore, to find the length of one wall, calculate the square root of 144, which is 12 feet. So, the length of one wall of the bedroom is 12 feet

Interpret the graph to determine the statement the manager at a building supply store can use to help a customer determine how much primer to purchase.
Each gallon of primer will cover a (minimum) (maximum) (multiple) of (200) (400)(600) square feet
Answer:
Each gallon of primer will cover a maximum of 200 square feet
Step-by-step explanation:
The x-axis of the graph is the area to paint in square feet. The y-axis of the graph is the number of gallons of primer needed.
We can see that 1 gallon of primer covers from 0 to 200 feet; 2 gallons of primer covers from 200 to 400 feet; etc.
This tells us that each gallon of primer covers a maximum of 200 square feet.

You have exactly 10 minutes to get to class for
your big test on lateral numbers! Your friend Gus
(who’s weirdly in to this sort of thing) says that class
is exactly 10,000 feet away. Let’s say you travel to
class at a rate of r feet/minute. You would like to get
there a few minutes early. More specifically, let’s say
you will arrive t minutes early.
a) Write an equation that relates r and t.
Find the equation of the circle with center at the origin that contains the point ( 12 , 9 ) (12,9).
Which value can fill in the blank in the function f(x)=|x| to make it's graph wider than that of the parent function, f(x)=|x|
To widen [tex]\( |x| \)[/tex]'s graph, use [tex]\( f(x) = |ax| \)[/tex] where [tex]\( a > 1 \),[/tex] stretching horizontally by multiplying [tex]\( x \) by \( a \).[/tex]
To make the graph of the function [tex]\( f(x) = |x| \)[/tex] wider than that of the parent function [tex]\( f(x) = |x| \)[/tex], we need to stretch the graph horizontally.
In the absolute value function [tex]\( f(x) = |x| \)[/tex], the "wideness" of the graph is determined by the coefficient of [tex]\( x \)[/tex], which affects the slope of the graph. When the coefficient of [tex]\( x \)[/tex] is greater than 1, the graph becomes wider, and when it's less than 1, the graph becomes narrower.
So, to make the graph wider, we can introduce a coefficient [tex]\( a \)[/tex] to the [tex]\( x \)[/tex]term inside the absolute value function. The function becomes [tex]\( f(x) = |ax| \), where \( a \)[/tex] is a positive constant greater than 1.
For example, if [tex]\( a = 2 \)[/tex], the function becomes [tex]\( f(x) = |2x| \)[/tex]. This means every \( x \) value in the function is multiplied by 2 before taking the absolute value. As a result, the graph stretches horizontally, making it wider than the parent function.
In conclusion, to make the graph wider than the parent function [tex]\( f(x) = |x| \)[/tex], we can use the function [tex]\( f(x) = |ax| \)[/tex], where [tex]\( a \)[/tex] is a positive constant greater than 1.

The perimeter of the triangle shown to the right is 115 feet . Find the length of each side
To find the length of each side of the triangle, we need to determine the length of the third side. The perimeter of the triangle is given as 115 feet. We know that the first side is 80 feet long and the second side is 105 feet long. To find the length of the third side, we subtract the sum of the lengths of the first two sides from the perimeter: 115 - 80 - 105 = 115 - 185 = -70.
Explanation:To find the length of each side of the triangle, we need to determine the length of the third side. The perimeter of the triangle is given as 115 feet. We know that the first side is 80 feet long and the second side is 105 feet long. To find the length of the third side, we subtract the sum of the lengths of the first two sides from the perimeter: 115 - 80 - 105 = 115 - 185 = -70.
However, since the length of a side cannot be negative, it means that there has been an error in the measurements or calculations. Please double-check the given information and calculations to ensure the accuracy of the question.

The floor of a shed has an area of 99 square feet. the floor is in the shape of a rectangle whose length is 7 feet less than twice the width. find the length and the width of the floor of the shed. use the formula, area equals=length times•width.
Final answer:
The width is 9 feet and the length is 11 feet.
Explanation:
The area of a shed floor is given as 99 square feet, and the floor is shaped like a rectangle. According to the problem, the length (L) of the floor is 7 feet less than twice the width (W). The relationship between length and width can be expressed as L = 2W - 7. We can use the area formula, which is Area = Length × Width.
Given the area (A) is 99 sq ft, we can set up the equation:
A = L × W
99 = (2W - 7) × W
Now we solve for W using the quadratic equation:
W2 - 7W + 99 = 0
Upon solving, we find that W = 9 feet (since the width cannot be negative). Now we can find the length L by substituting W into the length expression:
L = 2 × 9 - 7 = 11 feet
Therefore, the width is 9 feet and the length is 11 feet.

To maximize learning, a ________ should be presented on a(n) ________ schedule.
To maximize learning, a CS + UCS should be presented on a(n) continuous schedule.
In here, CS means conditional stimulus while UCS is the unconditioned stimulus. Taking for example, let us imagine that the smell of food is the unconditioned stimulus, the feeling of hunger in response to that specific smell is a unconditioned response, and then the sound of the whistle is the conditioned stimulus.
Suppose the number $1155$ is written as the product of three positive integers. What is the smallest possible value of the sum of those three integers?
First off, let us find for the prime factors of this number, 1155. The prime factors are:
3 * 5 * 7 * 11 = 1155
3, 5, 7, 11
Since there are 4 prime factors, we multiply the two smallest prime factors to make this into three, so multiply 3 and 5, so:
15, 7, 11
Now the smallest possible sum is:
15 + 7 + 11 = 33
Answer:
33
