What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We are given that Adrian bought a jacket that costs 11 dollars and a scarf that costs 15 dollars.
At the counter, he received a discount. If he only paid 22 dollars total, then
Total cost 11 + 15 = 26
But 26 - 22 = 4
Therefore, the discount was 4 dollar.

Find x and y
Pythagorean theorem
Answer:
x = 2√11
y = 4√47
Step-by-step explanation:
x^2 + 10^2 = 12^2
x^2 + 100 = 144
x^2 = 144 - 100
x^2 = 44
x = 2√11
x^2 + 12^2 = y^2
44 + 144 = y^2
188 = y^2
y = 2√47

Answer:
x=4, y =5
Step-by-step explanation:
there's no factorization involved, just elimination and substitution. First subtract equation 1 and 2. The x's cancel out and you get y by itself and can solve for it. Then plug the value of y into equation 2 and solve for x and you get it. (In my picture I put value of y in equation 1 but your question asks for putting it in equation 2 so do that instead)
the line Plus shows the differences some students jumped during a field day competition what fraction of the students jumped 5 1/2
Answer:
⅛
Step-by-step explanation:
Each mark (x) on the plot presents the distance that each student jumped.
There are 24 marks there, so it means there is a total of 24 students whose distance jumped were recorded.
Number of students that jumped 5½ ft = 3
Fraction of the students that jumped 5½ ft = no of students that jumped 5½ ft / total number of students

Using the Pythagoras theorem, the value of y is [tex]6\sqrt{7}[/tex], and the value that goes in the green box is 6.
What is Pythagoras Theorem?
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side.
Mark the intersections as A, B, C, and D.
It is given that BC=12 and CD=9.
The relationship between the height on the hypotenuse of a right triangle and the two line segments it generates on the hypotenuse is described by the right triangle altitude theorem, also known as the geometric mean theorem. It claims that the altitude is equal to the geometric mean of the two segments.
Apply the geometric mean theorem -
(AC)^2 = BC x CD
(AC)^2 = 12 x 9
(AC)^2 = 108
AC = [tex]\sqrt{108}[/tex]
AC = [tex]6\sqrt{3}[/tex]
Triangle ABC is a right-angled triangle, so apply Pythagoras theorem -
(AB)^2=(BC)^2+(AC)^2
(AB)^2=(12)^2+([tex]6\sqrt{3}[/tex])^2
(AB)^2=144+108
(AB)^2=252
AB=[tex]\sqrt{252}[/tex]
AB=[tex]6\sqrt{7}[/tex]
Therefore, the value of y is obtained as [tex]6\sqrt{7}[/tex].

Answer:
3/4
Step-by-step explanation:
4/8 can be simplified by dividing 2 from the numerator and denominator, which equals 2/4.
This turns the equation into 2/4 + 1/4, giving you a common denominator.
Answer:
Both B & C answers are correct
Step-by-step explanation:
To solve these two fractions, 1st you have to make both the numerator and the denominator the same.
For that, you can multiply both the numerator and the denominator of 1/4 by 2.

Whose inverses are also functions
Functions whose inverses are also functions.
What is inverse function?Inverse function is represented by [tex]f^{-1}[/tex] with regards to the original function and the domain of the original function becomes the range of inverse function and the range of the given function becomes the domain of the inverse function. The graph of the inverse function is obtained by swapping (x, y) with (y, x) with reference to the line y = x.
If a horizontal line intersects the original function in a single region, the function is a one-to-one function and inverse is also a function.
Every function has an inverse, but not every inverse will be a function. The inverse may fail the vertical line test. If the original function is a one-to-one function, then its inverse will be a function. A one-to-one function not only passes the vertical line test, it also passes a horizontal line test.
Therefore, functions whose inverses are also functions.

An 80% confidence interval is found to be (12, 20). What is the margin of
error?
A. 4.
B. 3.2
C. 6.4
D. 8
An 80% confidence interval is found to be (12, 20). Thus, the margin of error is 8.
How to interpret the confidence interval?Suppose the confidence interval at P% for some parameter's values is given by
[tex]x \pm y[/tex]
That means that parameter's estimated value is P% probable to lie in the interval
[x-y,x+y]
In most of the cases, the confidence interval is constructed around the mean, and the absolute distance from the mean on right or left side of the mean is called the margin of error.
Thus, we get: Confidence interval [tex]limits= \overline{x} \pm MOE[/tex]
The width of the confidence interval
20-12 = 8 units.
That cuts in half to get 8/2 = 4 which is the margin of error.
The center of the confidence interval
(12+20)/2
= 32/2
= 16.
So, 16+4 = 20, which is the right endpoint.
Also, 16-4 = 12, which is the left endpoint.

Barren's net worth statement exists shown to the right.
What is meant by net worth statement?Your total worth, including both financial and non-financial assets, equals your net worth less any outstanding obligations.
Using a net worth statement, you can view your financial situation at any given time. It is comparable to a "financial snapshot," showing the dollar amounts of your assets and liabilities (liabilities or debts).
Assets - Liabilities = Net Worth is the equation for calculating net worth.

Option -A is correct that is the order of the children by age, from oldest to youngest is Paul, Phillip, Annie, Chris.
Given that,
There are 4 children's. The names of the children's are Philip, Annie, Paul and Chris.
Philip is twice as old as Annie. Paul is 4 years older than Phillip and Chris is 2 years younger than Annie.
We have to find which represents the order of the children by age, from oldest to youngest.
We know that,
Lets us take the ages if the children's as a,b,c,d of Philip, Annie, Paul and Chris.
Philip is twice as old as Annie.
That means a = 2b
Paul is 4 years older than Phillip and
That mean c =4+a
Chris is 2 years younger than Annie.
That means d=b-2
So,
If we take the age of Philips as 20
Then Annie is 10, Paul is 24 and Chris is 8.
Therefore, Option -A is correct that is the order of the children by age, from oldest to youngest is Paul, Phillip, Annie, Chris .

A spinner has regions numbered 1 through 18. What is the probability that ___________________
the spinner, spun once, will stop on an even number or a multiple of 3?
Answer:
Probability that the spinner stop on an even number or a multiple of 3 = [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Given - A spinner has regions numbered 1 through 18.
To find - What is the probability that the spinner, spun once, will stop on an even number or a multiple of 3?
Solution -
Given that,
A spinner has regions numbered 1 through 18.
So,
The sample space, S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18}
i.e.
n(S) = 18
Now,
Let A be the outcomes that gives even number or a multiple of 3,
Then
A = {2, 3, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18}
i.e.
n(A) = 12
∴ we get
Probability that the spinner stop on an even number or a multiple of 3 = [tex]\frac{n(A)}{n(S)}[/tex]
= [tex]\frac{12}{18}[/tex]
= [tex]\frac{2}{3}[/tex]
i.e.
Probability that the spinner stop on an even number or a multiple of 3 = [tex]\frac{2}{3}[/tex]
