x = 2 , y' = 70 , x' = 30 : by using the property of SAS(side angle side) in ΔKMN and ΔKLI as they were similar polygon.
What is SAS property of triangle ?The property of a triangle whose two sides and the angle between these sides are stated is "SAS," which stands for "Side, Angle, Side". The SAS formula can be used to determine the area of a given triangle ABC with two known sides and an included angle between these sides.
Assume that the triangle's three sides are a, b, and c.
A SAS Triangle's perimeter
The following formula can be used to determine a triangle's area using SAS:
When sides "b" and "c" are known, along with angle A, the triangle's area is equal to: 1/2 bc sin(A)
The area of the triangle is equal to 1/2 ab sin(C) when sides 'b' and 'a' as well as included angle B are known
when sides "a" and "c" were added using SAS in triangle 1ΔMKN ~ ΔJKL
So, MN/KN = JL/KL
(x+1)/12 = (3x-2)/32
∴ 5x = 10 ⇒ x = 2
Using same property (SAS) in triangle 2
J = 80
∴ 30 = <x'
∵ in a triangle sum of angles is equal to 180° so, y' + <
J + 30 = 180
∴ <J = 80
then, y' = 70 and x' = 30

What is the value of x?
Enter your answer in the box.
Step-by-step explanation:
angle bisector theorem :
the ratio of the 2 baseline segments is the same as the ratio of the 2 legs of the main triangle.
in our case :
44.8/56 = (x + 4)/35
x + 4 = 44.8×35/56 = 44.8×5/8 = 28 mm
x = 24
FYI : one way of explaining the theorem is : we could see this as 2 projections originating from E at the same angle but onto a tilted projection screen.
the length on the projection screen (HD or GD) is directly related to the distance from the projection point to the end of the tilted projection : ED or EG. and so the ratios of both projections must be equal (due to the equal angle).
so, in our case
35/56 = (x + 4)/44.8
which leads, of course, to the same result
44.8×35/56 = x + 4

The consequence of the two functions f(x) = (1 / 6) · ∛x and g(x) = 6 · x³ by composition is f[g (x)] = (1 / 6) · ∛3 · x and g[f (x)] = (1 / 6) · x³, respectively.
How to use composition between two functions
In this question we must use the definition of composition between two functions f and g, where the independent variable of the function f is substituted by function g. That is to say:
f ° g (x) = f [g(x)]
If we know that f(x) = (1 / 6) · ∛x and g(x) = 6 · x³, then the result of each composition is:
f [g (x)] = (1 / 6) · ∛(6 · x³)
f[g (x)] = (1 / 6) · ∛3 · x
g[f (x)] = 6 · [(1 / 6) · ∛(6 · x³)]³
g[f (x)] = 6 · (1 / 216) · (6 · x³)
g[f (x)] = (1 / 6) · x³
The results of the compositions of the two functions f(x) = (1 / 6) · ∛x and g(x) = 6 · x³ are f[g (x)] = (1 / 6) · ∛3 · x and g[f (x)] = (1 / 6) · x³, respectively.

A jar contains three marbles; 1 yellow (y), 1 orange (o), and 1 red (r). Which list shows all the possible outcomes for choosing two marbles at random from the jar if the first marble is replaced after it is drawn?
The list that shows all the possible outcomes for choosing two marbles at random is yy, oo, ro, yo, oy, ry, yr, or, rr
How to determine the list of possible outcomes?From the question, we have the following parameters that can be used in our computation:
Orange = o
Red = r
Yellow = y
From the question, we understand that the selection is with replacement
This means that it is possible to select a marble two times
So, we have the following representation
yy oo ro
yo oy ry
yr or rr
Hence, the list is yy, oo, ro, yo, oy, ry, yr, or, rr

What is a residual for a multiple regression model and the data that is used to create it? select one.
The difference between the actual value of the response variable and the corresponding predicted value(regression error) using the multiple regression model is the correct option.
A residual is a measurement of the vertical distance between a point and the regression line. It is just the discrepancy between an actual value observed and a value that was projected.
To ensure that the requirements for making conclusions about the coefficients in a linear model have been met, one should always perform a residual analysis.
In regression analysis, a residual is the discrepancy between an observed value and a predicted value.
It is determined by,
Residual = Observed value – Predicted value
The residual is the discrepancy between the expected value and the actual value.
Observed value minus predicted value equals residual.

To hire an accountant to prepare taxes costs a flat fee and an additional hourly rate. The amount the accountant costs can
be modeled by the function A(x) = 150 + 35x, where x represents the number of hours the accountant works to prepare the
taxes and 150 represents the flat fee. What is the value of A(220) and its interpretation?
OA(220) = 7850; If the accountant takes 220 hours to prepare the taxes, the cost will be $7,850.
OA(220) = 7850; If the accountant takes 7,850 hours to prepare the taxes, the cost will be $220.
OA(220) = 2; If the accountant takes 220 hours to prepare the taxes, the cost will be $2.
2
OA(220) = 2; If the account takes 2 hours to prepare the taxes, the cost will be $220.
A(220) = 7850; If the accountant takes 220 hours to prepare the taxes, the cost will be $7,850.
Hence option (A) is correct.
What is a linear equation in one variable?
The linear equation in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
The cost function is A(x) = 150 + 35x
We have to find the value of A(220), so put x = 220 in the given cost function, we get
A(x) = 150 + 35x
A(220)= 150 + 35(220)
= 150 + 7700
= 7850 dollars
Hence, A(220) = 7850; If the accountant takes 220 hours to prepare the taxes, the cost will be $7,850.

Solve each system by elimination: 4x+3y=19 3x-4y=8
Answer: x =4 , y =1
Step-by-step explanation:
Multiply the first equation by 4,and multiply the second equation by 3.
4(4x+3y=19)
3(3x−4y=8)
Becomes:
16x+12y=76
9x−12y=24
Add these equations to eliminate y:
25x=100
Then solve 25x=100 for x:
25x=100
(Divide both sides by 25)
x =4
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
4x+3y=19
Substitute4forxin4x+3y=19:
(4)(4)+3y=19
3y+16=19( Simplify both sides of the equation)

The area of a given triangle is 35 square meters. The height of the triangle is (g-11) meters and the base is (g- 8) meters.
area of triangle = (b × h) ÷ 2
where b is the base so (g - 8)m,
h is the height so (g - 11)m
and area is 35
35 = (g - 11) × (g - 8) /2
35 = g² - 19g + 88 / 2
35 = 1/2g² - 19/2g + 44
1/2g² - 19/2g + 9 = 0
use the quadratic formula to find the two values of g and you will get:
g = 18 and g = 1
if we use g as 1 we will get negative metres for the values for the base and height so we use g = 18 instead!
base = (18) - 8
= 10m
height = (18) - 11
= 7m
