Enter a compound inequality to show the levels that are within each range. Then graph the solutions.
A typical acoustic guitar has a range of three octaves. When the guitar is tuned to "concert pitch," the range of frequencies for those three octaves is between 82.4 Hertz and 659.2 Hertz inclusive.
The compound inequality that represents the range of frequencies for a guitar tuned to "concert pitch" using the variable f is
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

Gina's number is 2 more than sara's. the sum of their numbers is 68. what are their numbers?
Answer:
Gina=35, Sara=33
Step-by-step explanation:
Gina's number is 2 more than Sara's.
Lets start by saying cookies as the number.
Sum = 2 numbers add together. The answer to the equation. Lik 5+5=10. 10 is the sum.
You only know that Gina has 2 more cookies than Sara.
If Sara has 3 cookies then Gina has 5 cookies. Whats the Sum? 8.
So, you figure out an random big number but, smaller than 68.
Lets do 68 to try now. So you do 68/2 = 34. You remember that Gina has 2 more than Sara. So, 35 cookies for Gina. So, you can guess that Sara has 33 cookies.

find the value of x and BC if B is between C and D CB=4x-9 BD=3x+5 and CD= 17
To find the value of x and BC, set up the equation CB + BD = CD and solve for x. The value of x is 3 and BC is 3.
Explanation:To find the value of x and BC, we can set up the equation CB + BD = CD and solve for x.
Substituting the given values CB = 4x - 9, BD = 3x + 5, and CD = 17, we get (4x - 9) + (3x + 5) = 17.
Combining like terms, we have 7x - 4 = 17. Solving for x, we find x = 3. Plugging this value back into CB = 4x - 9, we get BC = 4(3) - 9 = 12 - 9 = 3.

A family’s well pumps on average 8 gal of water per min. The well’s tank had 1200 gal of water in the morning. Which equation models the amount of water in the tank y after it has been pumping for x min?
it pumps 8 gallons a minute so it is 8x ( 8 gallons times x minutes)
you then need to subtract that amount from 1200
lets say it pumped for 10 minutes, 8 *10 = -80
1200 - 80 =1120
now the answers you have to choose from are kind of tricky because they don't give you the easiet one
so using the numbers above
the formula would be
1120 = -80+1200 =
y =-8x +1200
Final answer:
The equation y = 1200 - 8x models the amount of water in the tank as it is being pumped out.
Explanation:
The equation that models the amount of water in the tank y after x minutes is:
y = 1200 - 8x
This equation represents the initial 1200 gallons of water in the tank decreasing by 8 gallons per minute as it is being pumped out over time.
At a local carnival, a hot dog costs $1.50 each and water costs $0.80 each. You want to buy food and water for yourself and your friends but do not want to spend more than $20. Which inequality represents how many hot dogs and how much water you can buy?
1.50x+0.80y≤20 is inequality represents how many hot dogs and how much water you can buy
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
Given,
a hot dog costs $1.50 each and water costs $0.80 each.
Let x be the amount of hot dog
y be the amount of water
As hot dog costs $1.50 each, 1.50x
water costs $0.80 each, so 0.80y
You want to buy food and water for yourself and your friends but do not want to spend more than $20
1.50x+0.80y≤20
Hence, 1.50x+0.80y≤20 is inequality represents how many hot dogs and how much water you can buy

The answer to the first question is "b. one," according to Euclid's First Postulate. The answer to the second question is "c. infinitely many," according to Euclid's Second Postulate. These principles form the foundation of Euclidean geometry.
In Euclidean geometry, there are fundamental postulates and theorems that govern the behavior of lines and angles in triangles. Let's address your questions:
1. How many lines can be drawn through point A perpendicular to segment BC?
Answer: There can be only one line drawn through point A that is perpendicular to segment BC. This follows from Euclid's First Postulate, which states that a straight line can be drawn between any two points. In this case, the straight line from point A to any point on segment BC is unique and perpendicular.
2. How many lines can be drawn through point C perpendicular to segment AB?
Answer: Infinitely many lines can be drawn through point C that are perpendicular to segment AB. This is based on Euclid's Second Postulate, which states that a straight line can be extended infinitely in both directions. So, you can draw as many lines as you like, all of which are perpendicular to segment AB, and they will extend infinitely in both directions.

324 calories in a 3-ounce serving in a unit rate
The unit rate of 324 calories in a 3-ounce serving is
108 calories per 1 ounce.
Given,
There are 324 calories in 3 ounce
We need to find the unit rate which means how many calories in one ounce.
We have,
In 3 ounces there are 324 calories.
We can write it as,
3 ounce = 324 calories
Dividing both sides by 3,
We get,
1 ounce = 324 / 3
1 ounce = 108
So,
In 1 ounce we have 108 calories.
This is our unit rate.
Thus the unit rate of 324 calories in a 3-ounce serving is 108 calories per 1 ounce.

Find the 55th derivative of y = cos(3x).
Final answer:
The 55th derivative of y = cos(3x) is recognized by repeating the derivative patterns of cosine functions and is found to be -27cos(3x).
Explanation:
The 55th derivative of y = cos(3x) can be found by recognizing that the derivatives of sine and cosine functions repeat every four steps. Considering the pattern cos(x) -> -sin(x) -> -cos(x) -> sin(x) -> cos(x), and that the derivative of cos(3x) is -3sin(3x), we can determine that the pattern repeats every four derivatives with a factor of 3n, where n is the number of times the derivative is taken.
The 55th derivative will be the same as the third derivative in the cycle, but with an iteration count of 55/4, which leaves a remainder of 3, so the 55th derivative will be -27cos(3x).

7a-5a (because when you cross the = you do the opposite)=-b+2b
2a=b

THIS IS WHAT HAVE FOR TASK 1:Here at CeCe`s NeckIace am willing to invest $150 in this business. b. I am going to make and sell necklace’s. They are easy and quick to make, are worn by everyone, and are also fairly popular. It will cost me about 25 dollars to make 40 necklace`s, which is about 2 dolllars (1.6) per necklace. c. I will be able to profit from them because the amount that I will end up selling will be more than the amount I end up spending and investing.
The inequality 1.6n ≤ 150 represents the max number of necklaces you can make within budget. Solving this gives n ≤ 93.75, meaning you can sell up to 93 necklaces. Total earnings are represented by E = np. The maximum earnings are 93p. Profit is calculated by deducting costs from earnings.
Explanation:For (a) given that the initial investment is $150 and the cost per necklace is $1.6, the number of necklaces you can make without exceeding this limit is represented by the inequality 1.6n ≤ 150, where n represents the number of necklaces.
For (b), to find the maximum number of necklaces you can make, divide the total investment by the cost per necklace. Solve the inequality 1.6n ≤ 150 by dividing both sides by 1.6: n ≤ 93.75. This means you can make and sell up to 93 necklaces without exceeding your investment. To graph this, draw a number line and mark a closed circle at 93 to indicate that this value is included in the solution.
For (c), if you let p be the price at which you sell each necklace, your total earnings will be represented as E = np, where E stands for earnings.
For (d), substituting n ≤ 93.75 into E = np, the maximum you can hope to earn is 93p.
For (e), the total profit will be E - $150 (initial investment) - $1.6n (cost of necklaces). This would lead to either making a profit or loss. The profit or loss would then be used in adjusting your business plans.

Step 1
Find the slope of the given line
we have
[tex]3x+4y=15[/tex]
Isolate the variable y
Subtract [tex]3x[/tex] both sides
[tex]3x+4y-3x=15-3x[/tex]
[tex]4y=-3x+15[/tex]
Divide by [tex]4[/tex] both sides
[tex]y=-\frac{3}{4}x+ \frac{15}{4}[/tex]
the slope of the given line is
[tex]m=-\frac{3}{4}[/tex]
Step 2
Find the equation of the line that passes through the point [tex](8,-2)[/tex] and is parallel to the given line
we know that
if two lines are parallel, then their slopes are equal
The equation of the line into point-slope form is equal to
