Passengers of flyaway airlines can purchase tickets for either business class or economy class. On one particular flight there were 154 passengers. Let x be the number of business class passengers and y be the number of economy class passengers on this flight.
Use the information above to write down an equation in x and y.
On this flight the cost of a ticket for each business class passenger was 320 euros and the cost of a ticket for each economy class passenger was 85 euros. The total amount that Flyaway Airlines received for these tickets was 14970 euros.
Use this information about the cost of the tickets to write down a second equation in x and y.
Find the value of x and the value of y.
The airlines finance officer write down the total amount received by the airline for these tickets as 14270 euros.
Find the percentage error.
Answer:
x = 8
y = 146
Error = 4.86%
Step-by-step explanation:
Number of business class passenger = x
and the economy class passenger = y
Total number of passengers = 154
x + y = 154 ------(1)
Cost of business class tickets and economy class tickets are €320 and €85 respectively.
Total amount received by airlines is €14970.
320x + 85y = 14970
64x + 17y = 2994 --------(2)
Multiply equation (1) by 17 and subtract from equation (2)
(64x + 17y) - (17x + 17y) = 2994 - 2618
47x = 376
x = 8
From equation (1),
8 + y = 154
y = 154 - 8
y = 146
Airline officer wrote down the amount received as €14270
Then difference from the actual amount received = 14970 - 14270
= €700
% Error = [tex]\frac{\text{Difference in amount}}{\text{Actual amount}}\times 100[/tex]
= [tex]\frac{700}{14970}\times 100[/tex]
= 4.676
≈ 4.68%
Therefore, x = 8 and y = 146
and % error = 4.68%

PLEASE HELP WITH 7TH GRADEE MATH!!!!
Answer:
D
Step-by-step explanation:
On the graph, the first action you see is a straight line going up. The key word you look for in the word explanations are "increase" and "constant rate". Then, the 2nd action you see is a straight line not going up or down, just staying on the same level. This could be called "remaining the same" or stopping/resting. Then, you see a straight line going down. You look for "decrease" at a "constant rate." D matches all of those.

I'm confused. Can someone help?
a.
The polynomial w^2+18w+84 cannot be factored
The perfect square trinomial is w^2+18w + 81
----------
The reason the original can't be factored is that solving w^2+18w+84=0 leads to no real solutions. Use the quadratic formula to see this. The graph of y = x^2+18x+84 shows there are no x intercepts. A solution and an x intercept are basically the same. The x intercept visually represents the solution.
w^2+18w+81 factors to (w+9)^2 which is the same as (w+9)(w+9). We can note that w^2+18w+81 is in the form a^2+2ab+b^2 with a = w and b = 9
================================================
b.
The polynomial y^2-10y+23 cannot be factored
The perfect square trinomial is y^2-10y + 25
---------
Using the quadratic formula, y^2-10y+23 = 0 has no rational solutions. The two irrational solutions mean that we can't factor over the rationals. Put another way, there are no two whole numbers such that they multiply to 23 and add to -10 at the same time.
If we want to complete the square for y^2-10y, we take half of the -10 to get -5, then square this to get 25. Therefore, y^2-10y+25 is a perfect square and it factors to (y-5)^2 or (y-5)(y-5)

15f) Determine the line of symmetry. y = x2+16x+64
The equation of the line of symmetry of the parabola y = x² + 16x + 64 will be x + 8 = 0.
What is the equation of the parabola?Let the point (h, k) be the vertex of the parabola and a be the leading coefficient. Then the equation of the parabola will be given as,
y = a(x - h)² + k
The equation of the parabola is given below.
y = x² + 16x + 64
Convert the standard equation into a vertex form. Then we have
y = x² + 16x + 64
y = (x + 8)²
We know that the line of symmetry passes through the vertex of the parabola. Then the equation of the line of symmetry is given as,
x + 8 = 0
The equation of the line of symmetry of the parabola y = x² + 16x + 64 will be x + 8 = 0.

Does the function f(x) = x^3-4x^2+2x-6/x-3 have a slant asymptote? If so, find an equation of the slant asymptote. If not, explain
Answer:
No slant asymptote.
Step-by-step explanation:
No it hasn't .
If we do the division we find the quotient is a trinomial in x^2 so not a straight line, so there is no slant asymptote.
The one asymptote is the vertical line x = 3, because when x = 3 the denominator becomes 0.
Final answer:
To find the slant asymptote for the given function f(x), perform long division of the numerator by the denominator. The result is a quadratic function, which is the equation of the slant asymptote, specifically y = x^2 - x - 3.
Explanation:
The function f(x) = (x^3 - 4x^2 + 2x - 6)/(x - 3) does indeed have a slant asymptote, since the degree of the numerator is exactly one more than the degree of the denominator. To find the equation of the slant asymptote, you may perform polynomial long division or synthetic division. You would divide x^3 - 4x^2 + 2x - 6 by x - 3 to obtain the quotient which will be the equation of the slant asymptote.
When you do that, you'll find that the quotient is x^2 - x - 3. Since there's no remainder, or the remainder is of lesser degree than the denominator, the function approaches the line y = x^2 - x - 3 as x approaches infinity or negative infinity. This quadratic function is the slant asymptote for f(x).

Sarah is renting a cabin for vacation and has two choices. Cabin Arents for $100 per day and has a
$50 insurance fee. Cabin B rents for $120 per day and has a $10 insurance fee. Which system of
equations below will determine when the two choices will have the same cost?
Answer:
x = 2 days
y = 250 $
Step-by-step explanation:
We call "y" total renting costs and "x" total vacation days
according to that in first case we have:
y = 100*x + 50
And for the second case
y = 120*x + 10 (1)
That two equation system represent the equation system of the situation, therefore if we solve that system we will determine the choises with same costs
equating these two equations:
100*x + 50 = 120*x + 10
50 - 10 = 120*x - 100*x
20*x = 40
x = 2 days
Plugging that value in any of the equation (1) or (2) we get y value
y = 120*2 + 10
y = 250 $

A flexible wire is bent into a semicircular arc. The length of AB is 18 meters. Find the length of the wire. Use 3.14 as an approximation for π .
Answer: 28.26 meters
Step-by-step explanation:
Hi, to answer this question we have to find the perimeter of the semicircle.
P = (2 π r ) /2 (perimeter of a circle divided by 2)
The length of AB is the diameter of the circle (18 meters)
Since
Diameter (d) = 2 radius (r)
Replacing with the value given:
18 =2r
18/2=r
9 =r
Back on the perimeter formula
P = (2 π r ) /2
Replacing with the values given
P = (2 x 3.14 x 9) /2
P = 28.26 meters
Answer:
he's right it is 28.26
