The percentage increase in the cost of the airline tickets is 38%.
What is the percentage increase?Percentage is the fraction of a number out of hundred. The sign that is used to represent percentages is %. Percentage is a measure of frequency. In order to convert a value to a percentage, multiply the value by 100.
in order to determine the percentage increase, multiply the fraction of the change in price and the initial price by 100.
Percentage increase = (change in price / initial price) 100
Change in price = new price - initial price = $310 - $225 = $85
Initial price = $225
($85 / $225) x 100 = 38%

Givin f(x) = 1/x+5 and g(x)=x-2. What are the restrictions of the domain of f(g(x))?
OX≠ -5
OX≠ -3
OX≠ 2
OThere are no restrictions
Answer:
Step-by-step explanation:
x cannot be -3 or 2
Step-by-step explanation:
f(g(x)) = 1 / (( x-2) +5)
= 1/ (x+3)
g(x) cannot have x=2
The domain is restricted where
f(x) has an restriction that x cannot be 5
so g(x) cannot be -5
-5 = x-2

A store has two types of animal feed available. Type A contains 3 pounds of oats and 3 pounds of corn per bag. Type B contains 1 pound of oats and 7 pounds of
corn per bag. A farmer wants to combine the two types so that the resulting mixture has at least 18 pounds of oats and at least 54 pounds of corn. The store
only has 11 bags of type A feed and 12 bags of type B feed in stock. Type A costs $4 per bag, and type B costs $1 per bag. How many bags of each type should
the farmer buy to minimize her cost?
Note that the ALEKS graphing calculator can be used to make computations easier.
Type A feed:
Type B feed:
bag(s)
bag(s)
The farmer will purchase five bags of kind A and six bags of type B.
Per bag, Type A includes 9 pounds of oats and 3 pounds of maize.
Per bag, Type B includes 2 pounds of oats and 10 pounds of maize.
The farmer is looking for a blend that comprises at least 57 pounds of oats and 75 pounds of maize.
Allow the farmer to mix type A feed = x pounds.
and feed type B = y pounds
(9x + 2y) pounds of oats when blended
Corn amount when combined: (3x + 10y) pounds
Oats equation: 9x + 2y = 57 ———— (1)
Corn equation: 3x + 10y = 75 ————- (2)
Subtract equation (2) from equation (2) by multiplying it by three (1)
3(3x + 10y) - (9x + 2y) = 75×3 - 57
9x + 30y - 9x - 2y = 225 - 57
28y = 168
y = 6 bags
derived from the equation (1)
9x + 2×6 = 57
9x + 12 = 57
9x = 57 - 12
9x = 45
x = 5 bags
Because the business has 15 bags of each sort, each bag costs $4.
As a result, the cost of 5 bags of type A and 6 bags of type B is = (54) + (64)
= 20 + 24
= $44
The farmer intends to buy five bags of kind A and six bags of type B.

If triangle LMN has an obtuse angle at vertex M, which statements could be true? Check all that apply.
Triangle LMN is an obtuse angle then, the angle at vertex L is acute, the angle at vertex N is acute.
The triangle LMN is an obtuse angle at the vertex M. So by the definition of obtuse angle triangle LMN is an obtuse angle.
As ∠M is an obtuse angle
So 90° < m∠M < 180°
By the property of a triangle,
m∠L + m∠M + m∠N = 180°
m∠M = 180° - (m∠L + m∠N)
90° < 180° - (m∠L + m∠N) < 180°
90° - 180° < -(m∠L + m∠N) < 0
-90° < -(m∠L + m∠N) < 0
90° >(m∠L + m∠N) > 0
90° > m∠L and 90° > m∠N
Therefore both angles L and N are acute angles.

find the area of the circle. Use 3.14 for pie. Do not round your answer.
Answer: A = 452.16 ft²
Step-by-step explanation:
This gives us the formula to solve for the area.
A = πr²
The radius (r) is the same as the diameter divided by 2.
24 ft / 2 = 12 ft
We will input these given values and solve.
A = πr²
A = (3.14)(12)²
A = 452.16 ft²
Answer:
452.16 ft²
Step-by-step explanation:
To find the radius, you divide the diameter (24) by 2, which equals 12. The area of a circle formula is πr². To find area, you do 12² * 3.14. That equals 144 * 3.14, which equals 452.16.

Create three probability application problems of your own. Solve your problems. Explain your answers.
In the above question, we need to from 3 probability questions and then give solutions for them
Example 1 : A coin is tossed three times. What is the probability of getting at least one head?
Solution : A coin is tossed 3 times then
Sample space = [HHH, HHT, HTH, THH, TTH, THT, HTT, TTT]
Total number of ways = 2 × 2 × 2 = 8
Favorable Cases = 7
P (A) = 7/8
OR
Probability (of getting at least one head) = 1 – P (no head)⇒ 1 – (1/8) = 7/8
Example 2 : Three red and four black balls are contained in a bag. Randomly, one ball gets taken out of the bag. Determine the probability that the drawn ball is
(i) black
(ii) not black
Solution :
Total number of balls in the bag are = 3 + 4 = 7 balls
Number of favorable outcomes or number of black balls in the bag = 4
(i) Probability getting black balls = [tex]\frac{number of favorable outcomes}{number of total outcomes}[/tex]
P(black ball) = [tex]\frac{4}{7}[/tex]
(ii) Probability getting no black balls = 1 - P(black ball)

A house has decreased in value by 35% since it was purchased. If the current value is $78,000, what was the value when it was purchased?
Answer: The value of the house when it was purchased was 120,000
Step-by-step explanation:
1) Set up the equation. Let x be the house.
x-x*35%= 78,000
First, the house decreases 35% of the cost of the original house. It now costs 78,000.
2) Solve the equation.
x-x*0.35 = 78,000
x-0.35x=78,000
0.65x = 78,000
x= 120,000
Find the values of a,b and c that would make the statements true.
1) (ax+2)(5x+b)=10x^2+bx+c
The values of a, b and c are a = 2, b = -10 and c = -20
How to determine the values of the variables?The equation is given as
(ax + 2)(5x + b) = 10x^2 + bx + c
Open the brackets
So, we have
5ax^2 + 10x + abx + 2b = 10x^2 + bx + c
By comparing the above equation.
We have the following set of equations
5a = 10
10 + ab = b
2b = c
By solving the equations, we have
a = 2
Substitute a = 2 in 10 + ab = b
10 + 2b = b
So, we have
b = -10
Substitute b = -10 in 2b = c
2(-10) = c
Evaluate
c = -20
Hence, the values of the variables are a = 2, b = -10 and c = -20

Use the intersect method to solve the equation. x^2 - 3x = x^2 -1
The coordinate that represent the solution of the equation -
x² - 3x = x² - 1 is (0.333, -0.8889).
What is equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given is the following equation -
x² - 3x = x² - 1
In order to solve it using intersect method, we will plot the graphs of both functions and find the point of intersection of graphs of both the equations.
Assume -
f(x) = x² - 3x
g(x) = x² - 1
Now, the point of intersection of both the graphs will be the solution to the equation given by -
f(x) = g(x)
It can be seen from the graph that, both the graphs intersect at the coordinate (0.333, -0.8889). This coordinate will be the solution set of the equation -
f(x) = g(x)
Therefore, the coordinate that represent the solution of the equation -
x² - 3x = x² - 1 is (0.333, -0.8889).

Reflect the given triangle over the y - axis [[3,6,3],[-3,3,3]]
By using a reflection over the y-axis, the coordinates of the image of the triangle are (- 3, - 3), (- 6, 3) and C'(x, y) = (- 3, 3).
How to determine the coordinates of the vertices of a triangle by rigid transformations
Rigid transformations are transformations applied on geometric loci such that the form of the construction is not altered. Reflections over the y-axis are examples of rigid transformations. In this problem we need to apply this kind of transformation on the three vertices of the triangle: A(x, y) = (3, - 3), B(x, y) = (6, 3), C(x, y) = (3, 3).
The reflection over the y-axis is described by the following formula:
P'(x, y) = P(x, y) + (- 2 · p, 0)
Where:
P(x, y) - Original pointP'(x, y) - Resulting pointp - x-Component of P(x, y).If we know that A(x, y) = (3, - 3), B(x, y) = (6, 3) and C(x, y) = (3, 3), then the image of the vertices of the triangle:
A'(x, y) = (3, - 3) + (- 6, 0)
A'(x, y) = (- 3, - 3)
B'(x, y) = (6, 3) + (- 12, 0)
B'(x, y) = (- 6, 3)
C'(x, y) = (3, 3) + (- 6, 0)
C'(x, y) = (- 3, 3)
Now we present the picture of the two triangles.
The coordinates of the image of the triangle are A'(x, y) = (- 3, - 3), B'(x, y) = (- 6, 3) and C'(x, y) = (- 3, 3).
