An airliner is 9.34 feet wide. The airline wants to install 5 seats in each row. The seats are each 1.46 feet wide. Rounded to the nearest tenth, about how much space would be left for the aisle?
About 2.0 feet space will be left for aisle.
Step-by-step explanation:
Width of airliner = 9.34 feet
Width on one seat = 1.46 feet
Seats to install = 5
Width of 5 seats = 5*1.46 = 7.3 feet
Space left for aisle = Width of airliner - width of 5 seats
[tex]Space\ left\ for\ aisle=9.34-7.3\\Space\ left\ for\ aisle=2.04\ feet[/tex]
Rounding off to nearest 10th
Space left for aisle = 2.0 feet
About 2.0 feet space will be left for aisle.

To find the space left for the aisle, we first calculate the total seat width (5 seats × 1.46 feet/seat) and subtract it from the airliner width (9.34 feet), resulting in 2.0 feet of space for the aisle when rounded to the nearest tenth.
Explanation:To calculate the available space for the aisle in an airliner, we first determine the total width consumed by the seats. Since each seat is 1.46 feet wide and there are 5 seats in a row, we multiply the width of one seat by the number of seats:
1.46 feet/seat × 5 seats = 7.3 feet
Next, we subtract the total width of the seats from the total width of the airliner to find the space left for the aisle:
9.34 feet (total width) - 7.3 feet (width of seats) = 2.04 feet
Therefore, rounded to the nearest tenth, there would be approximately 2.0 feet of space left for the aisle.
The price of a toaster increase 10% to $40. What is the original price of the toaster before the increase?
Answer:
36.36
Step-by-step explanation:
We can express 10% as a decimal by multiplying it by (1/100), resulting in 0.1. Therefore, adding 0.1 of the original price, or x, to the price will result in 40, so x+0.1*x=40
= 1.1x
Dividing both sides by 1.1, we get that x, or the original price, is $36.36 (approximately).
Carter is a songwriter who collects royalties on his songs whenever they are played in a commercial or a movie. Carter will earn $50 every time one of his songs is played in a commercial and he will earn $130 every time one of his songs is played in a movie. Carter earned a total of $1000 in royalties on 12 commercials and movies. Determine the number of commercials and the number of movies on which Carter's songs were played.
Answer:
Number of songs played in commercial are 7 and Number of songs played in movie are 5.
Step-by-step explanation:
Let Number of songs played in commercial be x
and Number of songs played in movie be y.
Total number of songs played =12
Hence,
[tex]x+y=12\ \ \ \ equation \ 1[/tex]
Also
Cost for songs played in commercial = $50
Cost for songs played in movie = $130
Total Money earned = $1000
Hence,
[tex]\$50x+\$130y=\$1000[/tex]
Dividing by 10 on both side we get;
[tex]\$5x+\$13y=\$100\ \ \ \ equation \ 2[/tex]
Now multiplying equation 1 by 5 we get;
[tex]5x+5y=60 \ \ \ \ equation \ 3[/tex]
Now Subtracting equation 3 from equation 2 we get;
[tex](5x+13y=100)- (5x+5y=60)\\8y=40\\y=\frac{40}{8}=5[/tex]
y = 5
x + y = 12
x + 5 = 12
x = 12 - 5
x = 7
Hence, Number of songs played in commercial are 7 and Number of songs played in movie are 5.

F=9/5c+32 a is there a constant of proportionality? Explain your reasoning
yes because in a standard form that that equation is in, it'd be y=mx=b. the m represents the constant of proportionality or the rate of change. another name for it is the slope. in this case, the 9/5 is the m & c is x. meaning that, there is one & it is 9/5
The variables y and x have a proportional relationship, and y = 7 when x = 2.
What is the value of y when x = 5?
Enter your answer in the box.
y = 17.5 when x = 5
Step-by-step explanation:
When two variables are in direct proportion i.e. change in one variable causes change in other variable it can be expressed mathematically as:
y∝x
when the proportionality symbol is removed a proportionality constant is introduced
So,
[tex]y = kx[/tex]
Putting y = 7 and x = 2
[tex]7 = k * 2\\k = \frac{7}{2}\\k = 3.5[/tex]
So the expression will be:
[tex]y = 3.5x[/tex]
Now putting x = 5
[tex]y = 3.5 * 5\\y = 17.5[/tex]
Hence,
y = 17.5 when x = 5

What are the possible values of the missing term of the geometric sequence 6,....,13.5?
Answer:
THE ANSWER IS 1.5
Step-by-step explanation:
13.5 is the 3rd and last value. 6 is the first value.
The formula you need to use is an= 3r^n-1
13.5=3r^3-1
THE REASON YOU USE 3 IS BECAUSE IN TOTAL THERE ARE 3 TERMS AND WE ARE SOLVING FOR ONE MISSING TERM.
Now we bring 3 over to 13.5 to get r alone because we are solving for r
13.5/3 =r^2
Now we want to get rid of the square root. So we...
√13.5/3 =√r^2
The final answer is 1.5=2
The expression x2 - 36y2 is equivalent to
Answer:
(x + 6y)(x - 6y)
Step-by-step explanation:
The expression x² - 36y² can be factored.
Since the expression is a difference (subtraction) between two numbers that are square (x² = x*x and 36y² = 6y*6y), the factoring can be done as a "difference of squares".
The rules is generalized as: [tex]x^{2} - y^{2} = (x - y)(x+y)[/tex]
To factor x² - 36y², take each square roots for each of the numbers and add and subtract between them.
x² - 36y²
= (√x² + √36y²)(√x² - √36y²)
= (x + 6y)(x - 6y)
f(x) 3x^2+x-3 g(x)=x^2-5x+1 find f(x)-g(x)
Answer:
2x² + 6x - 4
Step-by-step explanation:
f(x) - g(x)
= 3x² + x - 3 - (x² - 5x + 1) ← distribute
= 3x² + x - 3 - x² + 5x - 1 ← collect like terms
= 2x² + 6x - 4
Answer:
f(x) - g(x) = 2x² - 4x - 2
Step-by-step explanation:
f(x) = 3x² + x - 3
g(x) = x² - 5x + 1
f(x) - g(x)
3x² + x - 3 - x² - 5x + 1
3x² - x² - 5x + x - 3 + 1
= 2x² - 4x - 2
f(x) - g(x) = 2x² - 4x - 2

There are 450 children that attend a high school. Of those students. 23%
are in the marching band. How many students are not in the marching
band?
Answer:
The number of students not in the marching band is 346.5
Step-by-step explanation:
Given as :
The total number of children that attend a high school = 450
The percentage of students in the marching band = 23 %
Let The number of students not in the marching band = x
Now ,
∵ The percentage of students in the marching band = 23 %
∴ The percentage of students not in the marching band = 100 % - 23 % = 77 %
So, The number of students not in the marching band = 77 % of the total number of students in the school
I.e The number of students not in the marching band = 77 % × 450
Or , The number of students not in the marching band = [tex]\frac{77}{100}[/tex] × 450
∴ The number of students not in the marching band = 346.5
And The number of students in the marching band = 450 - 346.5 = 103.5
Hence The number of students not in the marching band is 346.5 Answer

Step-by-step explanation:
At the market, 8 apples cost $4dollar. How much do 9 apples cost?
Answer: $4.50 for 9 apples
Step-by-step explanation: To find out how much it is for 1 apple, we need to find the unit price of 1 apple which is the cost per apple.
Since we know that it costs $4 for 8 apples, to find the cost for 1 apple, we need to divide 8 into $4 or 4 divided by 8 which is 0.5 of 50 cents per apple.
Since we know that it costs 50 cents per apple, to find the cost for 9 apples, we will need to multiply .50 by 9.
(.50) (9) = 4.50
Therefore, it will cost $4.50 for 9 apples.

use the rational exponent property to write an equivalent expression for
[tex] \sqrt[5]{n ^{4} } + 3 - 12[/tex]
Using the rational exponent property, an equivalent expression for[tex]\(x^{3/4}\[/tex] can be written as[tex]\(\sqrt[4]{x^3}\).[/tex]
Explanation:The rational exponent property states that for any real number a and positive integer[tex]\(n\), \(a^{m/n} = \sqrt[n]{a^m}\)[/tex] . Applying this property to the given expression[tex]\(x^{3/4}\[/tex] ), where (m = 3) and (n = 4), we can rewrite it as [tex]\(\sqrt[4]{x^3}\)[/tex] . This is derived by taking the fourth root of [tex]\(x^3\),[/tex] which is equivalent to raising [tex]\(x^3\)[/tex] to the power of[tex]\(1/4\).[/tex]
To further understand this, consider the original expression [tex]\(x^{3/4}\).[/tex] This represents the fourth root of [tex]\(x^3\)[/tex] , as the numerator 3 indicates the power to which x is raised, and the denominator 4 indicates the root. Expressing it as [tex]\(\sqrt[4]{x^3}\)[/tex] provides a clearer representation of the same mathematical concept, emphasizing the fourth root of [tex]\(x^3\).[/tex]
In mathematical notation, the rational exponent property is a useful tool for simplifying expressions involving fractional exponents. It allows us to transform expressions between radical form and exponent form, providing flexibility in mathematical manipulations and aiding in the understanding of the underlying concepts.

Marty ordered three extremely accurate and scientific water-balloon launchers from a mail order catalog (one for himself and two for his friends). The total price including shipping charges was $50. If the total shipping cost was $5, how much did each launcher cost?
Answer:
The price of each launcher is $ 15 .
Step-by-step explanation:
Given as :
The total price of three water balloon launchers including shipping charges = $50
The cost of the three shipping = $ 5
So, The price of water balloon launchers excluding shipping charges = $50-$5 = $ 45
Now,
∵ The price of 3 balloon launcher = $45
∴, The price of 1 balloon launcher = [tex]\frac{45}{3}[/tex] = $15
Hence The price of each launcher is $ 15 . Answer
is this a function ?
