The selling price of a shirt should be $8.97.
What is gain or profit?The profit or gain is equal to the selling price minus the cost price. Loss is equal to the cost price minus the selling price.
Given that, a store bought shirts for $5.75 each and profit percent = 65%.
We know that, Selling price = (100+Profit%)/100 ×CP
Here, Selling price =(100+65)/100 ×5.75
= 1.56×5.75
= $8.97
Therefore, the selling price of a shirt should be $8.97.

∠A and ∠B are vertical angles. If m∠A=(7x−18) ∘ and m∠B=(6x−8) ∘ , then find the measure of ∠A.
The measure of angle A is 52 degree.
What is the measure of angle A?Vertical angles are angles that are opposite of each other when two lines crosses, they are congruent.
Given that;
Angle A = ( 7x - 18 )∘Angle B = ( 6x - 8)∘Since vertical angles are congruent,
Angle A = Angle B
Plug in the given values
( 7x - 18 ) = ( 6x - 8)
Solve for x
7x - 18 = 6x - 8
7x - 6x = -8 + 18
x = -8 + 18
x = 10
Hence, angle A will be;
Angle A = 7x - 18

____= third consecutive even integer
Equation:
Solve:
Answer: 28, 30, 32
Step-by-step explanation: The first integer is 28, the second is 30, and the third is 32. The difference from the first integer and the last integer should be 4. x is the first integer, so the equation is:
x+x+2+x+4=90
The first integer plus the second integer(x+2) plus the third integer(x+4) equals 90. Now solve.
x+x+2+x+4=90
3x+6=90
-6 -6
3x=84
/3 /3
x=28
So the first integer is 28, second is 30, third is 32.

What is triangle ?
Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees.
Let's call the two legs of the right triangle a and b, and the hypotenuse c. The hypotenuse is the side opposite the right angle, so in this case, we have c = 29. We also know that one of the acute angles is 71 degrees.
Using trigonometry, we can use the tangent function to find the length of the base:
tan(71) = a/b
We can solve for b by multiplying both sides by b:
b tan(71) = a
Now we can substitute c = 29 and solve for b:
b = c / tan(71)
b = 29 / tan(71)
b ≈ 8.71
Hence, The length of the base is approximately 8.71 units.

The distance from the school to the mirror is 50 ft.
The height of the student is 5.1 ft.
What is the distance d between the student and the mirror?
Show all your work
The distance between the student and the mirror is apprοximately 29.41 feet.
What do you mean by Distance?Distance is a numerical measurement of hοw far apart or how far away objects or lοcations are from each other. It is a physical quantity that is usually expressed in units such as meters, kilοmeters, miles, οr feet. Distance is a scalar quantity, meaning it οnly has magnitude and nο direction.
To sοlve the problem, we can use the similar triangles prοperty of geometry. Let's denοte the distance between the student and the mirrοr as d. Then, we can set up the follοwing proportion:
(student height + height of mirrοr) / distance frοm student to mirror = height of schοol / distance from mirrοr to school
Plugging in the given values, we get:
(5.1 + 0) / d = 30 / (50 + d)
Simplifying and sοlving for d, we get:
5.1d + 0 = 150
d = 29.41
Therefοre, the distance between the student and the mirrοr is apprοximately 29.41 feet.

What is the distance d between the student and the mirror?
The distance d between the student and the mirror is given by the similar triangles are d = 10.5 feet
What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the triangles be represented as ΔABC and ΔCDE
Now , they are similar triangles
The measure of AB = height of the school = 30 feet
The measure of BC = distance from the school to the mirror = 50 feet
And ,
The measure of DE = height of the student = 6.3 feet
The measure of CD = distance d between the student and the mirror
So , the corresponding sides of similar triangles are in the same ratio
On simplifying the equation , we get
BC / AB = CD / DE
And , 50 / 30 = d / 6.3
Multiply by 6.3 on both sides , we get
d = ( 5/3 ) x 6.3

select the statement which is true about the functions over the interval [1,2]
The true statement is (b) Function 2 has the lowest average rate
How to determine the true statementWe start by calculating the average rates of each function
The interval is given as [1, 2]
For Function 1
We have
f(1) = -3
f(2) = 3
The average rate is then calculated as
Average rate = [f(2) - f(1)]/[2 - 1]
Average rate = (3 + 3)/1
Average rate = 6
For Function 2
We have
f(1) = (1/4)^1 + 4 = 4.25
f(2) = (1/4)^2 + 4 = 4.0625
The average rate is then calculated as
Average rate = [f(2) - f(1)]/[2 - 1]
Average rate = (4.0625 - 4.25)/1
Average rate =-0.1875
For Function 2
We have
f(1) = -2
f(2) = 0
The average rate is then calculated as
Average rate = [f(2) - f(1)]/[2 - 1]

what is the that justen wins
The probability that Justen wins is 4/9.
Determine the probabilityThe probability that Justen wins is determined by the likelihood that the highest number rolled on the two dice is a 1, 2, 3, or 4. To find this probability, we can first calculate the probability that the highest number rolled is a 5 or 6, which is what would cause Gaberil to win.
The probability of rolling a 5 or 6 on one die is 2/6, or 1/3. The probability of rolling a 5 or 6 on both dice is (1/3) * (1/3) = 1/9.
However, we also need to account for the possibility that one die rolls a 5 or 6 and the other does not.
This can happen in two ways: either the first die rolls a 5 or 6 and the second does not, or the first die does not roll a 5 or 6 and the second does.
The probability of each of these scenarios is (1/3) * (2/3) = 2/9.
So the total probability of Gaberil winning is 1/9 + 2/9 + 2/9 = 5/9.
Since there are only two possible outcomes (either Gaberil wins or Justen wins), the probability of Justen winning is 1 - the probability of Gaberil winning. So the probability of Justen winning is 1 - 5/9 = 4/9.
Therefore, the probability that Justen wins is 4/9.

Figure ABCD is a square. If AC+BD=56, what is the length of AX?
Figure ABCD is a square. If AC+BD=56, the length of AX is 28.
How did we get the value?Since ABCD is a square, all sides have the same length, let's call it "x".
We know that the sum of the diagonals of a square is equal to twice the length of a side, so AC + BD = 2x.
Therefore, 56 = 2x, and x = 28.
So the length of AX (or any side of the square) is 28 units
