Hey Rachael is removed from a rectangle to create the shaded region chandelier find the area of the shaded region be sure to include the correct unit in youranswer
Answer:
34.5 cm²
Step-by-step explanation:
The area of the shaded region is the area of the rectangle minus the area of the right triangle.
The area of the rectangle is simply the length 7 cm multiplied by the width 6 cm.
To find the area of the right triangle, you must first find the base and height of the triangle.
The two lengths can be found this way:
7 cm - 2 cm = 5 cm
6 cm - 3 cm = 3 cm
area of shaded region = LW - bh/2
area of shaded region = 7 cm × 6 cm - 5 cm × 3 cm / 2
area of shaded region = 42 cm² - 7.5 cm²
area of shaded region = 34.5 cm²

Answer:
m∠F = 100
Step-by-step explanation:
Sum of interior angles in a hexagon is 720.
( x - 60 ) + ( x - 40 ) + 130 + 120 + 110 + ( x - 20 ) = 720
x + x + x - 60 - 40 - 20 + 130 + 120 + 110 = 720
3x - 120 + 120 + 130 + 110 = 720
3x + 130 + 110 = 720
3x + 240 = 720
3x = 720 - 240
3x = 480
x = 480 / 3
x = 120
m∠F = x - 20
Substitute the value of x,
m∠F = 120 - 20
m∠F = 100
The net of the figure shown is made of which set of
shapes?
O 3 triangles and 1 square
O 3 triangles and 1 rectangle that is not a square
О 4 triangles and 1 square
O4 triangles and 1 rectangle that is not a square
Step-by-step explanation:
It's not 3 triangles and 1 square because you need four triangles to make the siding and the square wont go anywhere because of how it's going to look.
It's not 3 triangles and 1 rectangle because still you need four to make the sides and a rectangle is too long.
4 triangles and 1 rectangle is still not correct because the rectangle on the bottom of the net is going to mess it up fir the whole shape.
So in conclusion, 4 triangles and 1 squares is the correct answer.
If y=x+4 then what is (x-y)^3

4^3 = 64
Three times a number plus three times a second number is negative twelve. Five times the first number plus twice the second is four
Consider the numbers as, if we assume our first number to be x and second number being y, then from the given information we will be having the following equations :
[tex]{:\implies \quad \begin{cases}\sf 3x+3y=-12\\ \\ \sf 5x+2y=4\end{cases}}[/tex]
Now, rewrite the second equation as ;
[tex]{:\implies \quad \sf 3(x+y)=-12}[/tex]
Divide both sides by 3 ;
[tex]{:\implies \quad \sf x+y=-4\quad ---(i)}[/tex]
Now, consider the second equation of the above cases
[tex]{:\implies \quad \sf 5x+2y=4\quad ---(ii)}[/tex]
Now, multiply (i) by 2 on both sides :
[tex]{:\implies \quad \sf 2x+2y=-8\quad ---(iii)}[/tex]
Now, subtracting (ii) from (iii) will give us :
[tex]{:\implies \quad \sf 2x+2y-(5x+2y)=-8-4}[/tex]
[tex]{:\implies \quad \sf 2x+2y-5x-2y=-12}[/tex]
[tex]{:\implies \quad \sf -3x=-12}[/tex]
[tex]{:\implies \quad \boxed{\bf{x=4}}}[/tex]
Now, putting x = 4 in (i), will give y + 4 = -4, then solving for y will yield [tex]{\boxed{\bf{y=-8}}}[/tex]
Hence, we can conclude that :
[tex]{\quad \qquad \longrightarrow \begin{cases}\bf x=4\\ \\ \bf y=-8\end{cases}}[/tex]

Solving Trig. Equations
In each solution, n is an arbitrary integer.
1. Nothing fancy, just take the inverse tangent.
tan(x) = -5
x = arctan(-5) + nπ
x = -arctan(5) + nπ
2. Recall the identity cos(2x) = 2 cos²(x) - 1, then factorize:
cos(2x) - 3 cos(x) + 2 = 0
(2 cos²(x) - 1) - 3 cos(x) + 2 = 0
2 cos²(x) - 3 cos(x) + 1 = 0
(2 cos(x) - 1) (cos(x) - 1) = 0
2 cos(x) - 1 = 0 or cos(x) - 1 = 0
cos(x) = 1/2 or cos(x) = 1
[x = arccos(1/2) + 2nπ or x = -arccos(1/2) + 2nπ]
… or x = arccos(1) + 2nπ
x = π/3 + 2nπ or x = -π/3 + 2nπ or x = 2nπ
3. By definition, csc(x) = 1/sin(x) :
csc(2x) + √2 = 0
csc(2x) = -√2
1/sin(2x) = -√2
sin(2x) = -1/√2
2x = arcsin(-1/√2) + 2nπ or 2x = π - arcsin(-1/√2) + 2nπ
2x = -π/4 + 2nπ or 2x = 5π/4 + 2nπ
x = -π/8 + nπ or x = 5π/8 + nπ
4. More factorization:
2 sin²(x) - sin(x) = 0
sin(x) (2 sin(x) - 1) = 0
sin(x) = 0 or 2 sin(x) - 1 = 0
sin(x) = 0 or sin(x) = 1/2
x = arcsin(0) + 2nπ
… or [x = arcsin(1/2) + 2nπ or x = π - arcsin(1/2) + 2nπ]
x = 2nπ or x = π/6 + 2nπ or x = 5π/6 + 2nπ
5. Yet more factorization. Also recall that |cos(x)| ≤ 1 for all x.
4 cos²(x) - 8 cos(x) + 3 = 0
(2 cos(x) - 3) (2 cos(x) - 1) = 0
2 cos(x) - 3 = 0 or 2 cos(x) - 1 = 0
cos(x) = 3/2 or cos(x) = 1/2
The first case gives no solution since 3/2 > 1.
x = arccos(1/2) + 2nπ or x = -arccos(1/2) + 2nπ
x = π/3 + 2nπ or x = -π/3 + 2nπ
6. Recall the identity sin(a - b) = sin(a) cos(b) - cos(a) sin(b).
sin(2x) cos(x) - cos(2x) sin(x) = -√3/2
sin(2x - x) = -√3/2
sin(x) = -√3/2
x = arcsin(-√3/2) + 2nπ or x = π - arcsin(-√3/2) + 2nπ
x = -π/3 + 2nπ or x = 4π/3 + 2nπ
Graph the function. f(x)=3/5x-5
Five members of a mystery-book club each read a 1,296-page book. Nine members of a fantasy-book club each read a 398-page book. How many more pages did the mystery-book club read than the fantasy-book club? Select all the correct equations or set of equations that could be used to solve the problem.
Answer:
2898

A sample of students is taken from the school's A honor roll. The school estimates that there are 360 students on the A honor roll. Using this sample how many students on the A honor roll are 8th graders. There are 14 8th graders on the A honor roll.
Answer:
Number of 7th grade = 360 - X
Step-by-step explanation:
As you can see this question is not complete and lacks the essential data. But we will try to create a mathematical expression to calculate the number of students on the A honor roll which are from &th grade. As we know: Total number of students on the A honor roll = 360 We are asked to calculate, number of students from 7th grade on the A honor roll. So, let's assume that "X" represents the all the students who are on the A honor roll except 7th grade. Mathematical Expression: Number of 7th Graders = Total number of students on the A honor roll - X Number of 7th Graders = 360 - X So, if you know the value of X, you can easily calculate the number of students which are from 7th grade on the A honor roll.
Answer:
There are 126 8th grade A honor roll students.
Step-by-step explanation:
Since there are 14 8th grade A honor roll students out of 40 A honor roll students. That means that the fraction is 14/40. After that we do 14/40x360 which results in 126.

Answer:
x = 2
Step-by-step explanation:
24 - 7x = 10
Rearrange terms,
-7x + 24 = 10
Subtract 24 from both sides,
-7x + 24 - 24 = 10 - 24
-7x = 10 - 24
-7x = -14
Divide by sides by -7,
[tex]\frac{-7x}{-7}=\frac{-14}{-7}[/tex]
[tex]x=\frac{-14}{-7}[/tex]
x = 2
