Answer:
3 inches
Step-by-step explanation:
Given that the volume of the rectangular prism or a cylinder needs to be \(258\frac{3}{4}\) cubic inches. The container being made is a rectangular prism with a height of \(11\frac{1}{2}\) inches and length of \(7\frac{1}{2}\) inches.
A rectangular prism is a polyhedron with six rectangular faces.
Therefore the required width (w) needed to produce a container with a volume of \(258\frac{3}{4}\) cubic inches is given by:
volume of a rectangular prism = height * width * length
Substituting:
\(258\frac{3}{4}\) = \(11\frac{1}{2}\) * \(7\frac{1}{2}\) * w
258.75 = 11.5 * 7.5 * w
w = 258.75 / (11.5 * 7.5)
w = 3 inches
The required width is 3 inches

The cosine of an angle for a right triangle is the length of the adjacent side divided by the hypotenuse.
See figure for graphic view relating to this calculation
Here we can see that the hypotenuse if l, the adjacent side to the angle θ is l-h so we get
cosθ = (l-h)/l
Multiplying both sides by l gives
lcosθ = l-h ==> h = l - lcosθ which simplifies to h = l(1-cosθ)
Q 18
For θ = 40°, cosθ = 0.766
h = 6(1-0.766) = 6(0.234) = 1.404 m

Gianna is a songwriter who collects royalties on her songs whenever they are played in a commercial or a movie. Gianna will earn $50 every time one of her songs is played in a commercial and she will earn $100 every time one of her songs is played in a movie. Gianna's songs were played on twice as many commercials as movies and her total earnings on the royalties from all commercials and movies was $800. Graphically solve a system of equations in order to determine the number of commercials, x,x, and the number of movies, y,y, on which Gianna's songs were played.
A graph of each function is shown in the image attached below.
The number of commercials (x) is equal to 8 commercials while the number of movies (y) is equal to 4 movies.
How to write and solve the system of equations graphically?In order to graphically solve the system of equations, we would write two (2) equations that models the situation by assigning variables to the number of commercials and number of movies respectively, and then translate the word problem into algebraic equation as follows:
Let the variable x represent the number of commercials.Let the variable y represent the number of movies.Since Gianna would earn $50 every time one of her songs is played in a commercial and $100 every time one of her songs is played in a movie, an equation which models it is given by;
50x + 100y = 800
Additionally, Gianna's songs were played on twice as many commercials as movies;
x = 2y
Next, we would use an online graphing calculator to plot the above system of equations with a point of intersection at (8, 4) as shown in the image attached below.

9. The Super Vision cable TV/Internet/phone provider advertises a flat $100 monthly fee for all
three services for a new customer. The rate is guaranteed for 5 years. Cable Zone normally
charges $46 for monthly home phone service, $36 for monthly Internet service, and $56 for
monthly cable television.
a. How much could a customer save during the first year by switching from Cable Zone to
Super Vision?
b. Super Vision raises the rates 23% after a new customer's first year, how much will a customer
who switched from Super Vision save in the second year?
c. If Super Vision raises the rates 18% for the third year compared to the second year, which
company is cheaper for the third year?
a. $456 would be the amount a customer could save during the first year by switching from Cable Zone to Super Vision.
b. Super Vision raises the rates 23% after a new customer's first year, a customer who switched from Super Vision save $180 in the second year.
c. Super Vision raises the rates 18% for the third year compared to the second year, for the third year, Cable Zone would be cheaper.
a. To calculate how much a customer could save during the first year by switching from Cable Zone to Super Vision, we need to compare the costs of the two providers.
Cable Zone charges $46 for monthly home phone service, $36 for monthly Internet service, and $56 for monthly cable television. Therefore, the total cost per month with Cable Zone is:
$46 (home phone) + $36 (Internet) + $56 (cable television) = $138
Super Vision, on the other hand, offers all three services for a flat $100 monthly fee. So, the customer would save:
$138 (Cable Zone cost) - $100 (Super Vision cost) = $38 per month
Therefore, during the first year, the customer could save:
$38 (monthly savings) * 12 (number of months) = $456
b. After the first year, Super Vision raises the rates by 23%. The new monthly fee would be:
$100 (original fee) + 23% (rate increase) * $100 (original fee) = $123
To calculate the savings in the second year, we need to compare the new Super Vision fee to the cost with Cable Zone:
$138 (Cable Zone cost) - $123 (Super Vision cost) = $15 per month
Therefore, in the second year, the customer would save:
$15 (monthly savings) * 12 (number of months) = $180
c. If Super Vision raises the rates by 18% for the third year compared to the second year, we need to calculate the new monthly fee. The new Super Vision fee would be:
$123 (second-year fee) + 18% (rate increase) * $123 (second-year fee) = $145.14
To determine which company is cheaper for the third year, we compare the new Super Vision fee to the cost with Cable Zone:
$138 (Cable Zone cost) - $145.14 (Super Vision cost) = -$7.14
In this case, the Super Vision cost is higher than the Cable Zone cost by $7.14 per month. Therefore, for the third year, Cable Zone would be cheaper.
Overall, during the three-year period, the customer would save a total of $456 (first year) + $180 (second year) = $636 by switching to Super Vision.

An angle measures 8° more than the measure of its complementary angle. What is the measure of each angle?
Answer:
41° and 49°
Step-by-step explanation:
Complementary angles are angles that sum up to 90°.
Let x represent the smaller angle, then the bigger angle will be represented with x + 8:
x + x + 8 = 90°
Add like terms.2x + 8 = 90°
Subtract 8 from both sides.2x = 82°
Divide both sides by 2.x = 41° this is the measure of smaller angle, then the bigger angle wpis 49°
The answer is:
⇨ 41 and 49Work/explanation:
If two angles are complementary, their measures add to 90°.
So we can set up an equation to find the angles. Let the unknown angle be w, and its complement will be w + 8:
w + w + 8 = 90
Combine like Terms
2w + 8 = 90
2w = 82
w= 41
The other angle measures 8° more than the measure of w:
41 + 8 = 49
Hence, the angles are 41 and 49°.Anything helps! Thank you :).

What are parallel Lines?The fundamental characteristics listed below make it simple to recognise parallel lines.
Straight lines that are always the same distance apart from one another are called parallel lines.No matter how far apart they are from one another, parallel lines can never intersect.First, Interior of ( 2y+ 34) = 180 - (2y + 34)
= 146- 2y
Now, using Corresponding Angle
74 = 146 - 2y
2y= 72
y= 72 / 2
y= 36
Second, Using Linear Pair
-7x+ 12 + (-8x+ 48)= 180
-7x + 12 - 8x + 48 = 180
-15x + 60 = 180
-15x = 120
x= -8

Egbert wants to establish a fund for his grandchild's college education. What lump sum must he deposit at a 7% annual interest rate, compounded quarterly, in order to have $40,000 in the fund at the end of 10 years? Fill in the values, plug into the formula, use algebra and your calculator to get the result. Round to the nearest cent.
Egbert must deposit $19,602.52 as a lump sum in order to have $40,000 in the fund at the end of 10 years.
To calculate the required lump sum deposit, we can use the formula for compound interest:
A = P\((1+r/n)^{nt}\)
Where:
A = the future value (desired amount in the fund) = $40,000
P = the initial principal (lump sum deposit we need to find)
r = the annual interest rate in decimal form = 7% = 0.07
n = the number of compounding periods per year = 4 (quarterly compounding)
t = the number of years = 10
Plugging in these values, the formula becomes:
$40,000 = P\((1+(0.07/4)^{(4*10)}\)
Simplifying further:
$40,000 = P\((1.0175)^{40}\)
Now we can solve for P by dividing both sides of the equation by
P = $40,000 /\((1.0175)^{40}\)
Using a calculator to evaluate the expression, we find:
P ≈ $19,602.52
Therefore, Egbert must deposit approximately $19,602.52 as a lump sum in order to have $40,000 in the fund at the end of 10 years.

(-9, -1)
EXPLANATION
- The starting point for the red line is (-11, 1)
- The lines intersect, that is, they touch each other. They intersect at point (-9, -1)
- The rate of change is the same as the slope.
The slope is gotten by picking any two points on the graph and finding:
\(\text{Slope = }\frac{y_{2\text{ }}-y_1}{x_{2\text{ }}-x_1}\)Let us pick points (-8, -2) and (-3, -6).
Therefore, the slope for the red line is:
\(\text{Slope = }\frac{-6\text{ - (-2)}}{-3-(-8)}\text{ = }\frac{-6\text{ + 2}}{-3\text{ + 8}}=\text{ }\frac{-4}{5}=\text{ -0.8}\)- For the blue line, let us pick points (-4, 0) and (0, 1)
The slope for the blue line is:
\(\text{Slope = }\frac{1\text{ - 0}}{0\text{ - (-4)}}\text{ = }\frac{1}{4}\)- The y intercept of the blue line is 1
- The solution of the system of lines in the graph is the point of intersection of both lines and that is (-9, -1)

What is an equation of the axis of symmetry of the parabola represented by y=-x^2+6x-4?
im giving brainliest!!
Answer:
Step-by-step explanation:
Take out a common factor of -1 from the first 2 terms
y = -(x^2 - 6x ) - 4
Take -6 and multiply it by 1/2 and square the result. Add inside the brackets
y = -(x^2 -6x +(-3)^2 ) - 4
y = -(x^2 - 6x + 9) - 4
Because you added nine inside the brackets add 9 outside the brackets
y = -(x^2 - 6x + 9) - 4 + 9
The reason you add 9 outside the brackets is because of the minus sign on the left of the brackets. Without that minus sign, you would subtract 9.
Result
y = -(x^2 - 6x + 9) + 5
Now what is inside the brackets is a perfect square
y= -(x -3)^2 + 5
The axis of symmetry is x = 3 (see the graph below)
