The table gives the average age of airplanes per airline at Camila’s local airport. By what percent is the number of airlines with an average airplane age of 14 less than the number of airlines with an average airplane age of 11 ?
Answers
The percentage that the number of airlines with an average airplane age of 14 is less than the number of airlines with an average airplane age of 11 is:
B. 20%.
What is a percentage?The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
[tex]P = \frac{a}{b} \times 100\%[/tex]
The percentage of airlines with an average age of 14 years is:
[tex]P = \frac{2}{15} \times 100\% = 13.33\%[/tex]
The percentage of airlines with an average age of 11 years is:
[tex]P = \frac{5}{15} \times 100\% = 33.33\%[/tex]
The difference is:
33.33% - 13.33% = 20%.
Hence option B is correct.

I am not sure if it is B or C, but I can say that it is not A since the figure in A is rotated. Figure in B kinda looks like a reflection then C because if the figures were translated then the corner should be at one side.

Given that ABCD is a parallelogram. Find the following
Answers
Answer:
m=8
m<A=83
m<D=97
Step-by-step explanation:
Angles that are opposite of each other in a parallelogram are equal. Knowing this, we can first conclude that angle A and angle C are equal. We can set up the following equation:
[tex]9m+11=8m+19[/tex]
Subtract both sides by 11
[tex]9m+11-11=8m+19-11\\9m=8m+8[/tex]
Subtract both sides by 8m
[tex]9m-8m=8m+8-8m\\m=8[/tex]
To calculate angle A, plug the value of m into its expression.
[tex]<A=9m+11\\<A=9(8)+11\\<A=72+11\\<A=83[/tex]
In a parallelogram, angles that share a side are supplementary, meaning they add up to 180 degrees. Therefore, angle A and angle D are supplementary. Knowing this, we can set up the following equation:
[tex]180=83+D[/tex]
Subtract both sides by 83
[tex]180-83=83+D-83\\97=D[/tex]

If x= 1/3 is one of the solutions of an equation then what is the factor that gave us this solution
Answers
Answer:
3x - 1 = 0
Step-by-step explanation:
If x = 1/3
multiply both sides by 3
3 * x = 1/3 * 3
3x = 1
Subtract 1 from both sides ;
3x - 1 = 1 - 1
3x - 1 = 0 ( the factor which gives the solution)
3x - 1 = 0
3x = 1
Doavide both sides by 3
3x / 3 = 1/3
x = 1/ 3

Actually Welcome to the Concept of the Equilateral Triangles.
Since, we know that, all the sides of a triangle are equal, hence it is a Equilateral triangle.
Equilateral triangle has one all angles equal to 60°.
so, major angle P = 60°
hence, 2x=60°
===> x = 30°
