Answer:
78
Step-by-step explanation:
Ratio of left-footed teachers to right-footed teachers = 3:13
18 left-footed teachers; 3x6 = 18 (3:13 is a simplified ratio and to get 18, you have to multiply 3 by 6)
13x6 = 78 (whatever you do to one side, you have to do the other)
78 right-footed teachers
The are 78 teachers are right footed.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
The ratio of the number of left footed teachers: the number of right footed teachers = 3:13
Total left footed teachers = 18
let the Common ratio be x.
Then , number of left footed teachers= 3x
and, number of right footed teachers= 13x
So, 3x= 18
x= 6
Hence, there are 78 teachers are right footed.

{(-2,0), (2,2), (2, -2), (7,3)}
Answer:
The final set is not a function.
Step-by-step explanation:
There are two x-values that are the same, making it not a function. Notice, this is not the same in the other sets, because each x corresponds to exactly one y-value in the other functions.

33×2=66
44×2=88
55×2=110
Answer:
^Refer to explanation:
Step-by-step explanation:
11 gold stars = 22 books
1 gold star = 22 ÷ 11 = 2
22 gold stars = 2 x 22 = 44 books

-8 - x = x - 4x
Answer:
−8−x=x−4x
Step 1: Simplify both sides of the equation.
−8−x=x−4x
−8+−x=x+−4x
−x−8=(x+−4x)(Combine Like Terms)
−x−8=−3x
−x−8=−3x
Step 2: Add 3x to both sides.
−x−8+3x=−3x+3x
2x−8=0
Step 3: Add 8 to both sides.
2x−8+8=0+8
2x=8
Step 4: Divide both sides by 2.

NEED HELP WITH GEOMETRY
Answer:
Please look down below
Step-by-step explanation:
∠1 + 69 + 47 = 180 (because straight line)
∠1 = 180 - 116
∠1 = 64
∠2 + ∠1 + 63 = 180 (because triangle)
∠2 + 64 + 63 = 180
∠2 = 180 - 127
∠2 = 53
∠3 + ∠1 = 180 (because straight line)
∠3 + 64 = 180
∠3 = 116
∠5 = ∠4 (given)
∠5 + ∠4 + ∠3 = 180
Denote ∠5 and ∠4 as x, so 2x
2x + ∠3 = 180
2x + 116 = 180
2x = 64
x = 32
∠5 = 32, ∠4 = 32
∠6 + 136 = 180 (because straight line)
∠6 = 44
∠7 + ∠6 + 47 = 180 (because triangle)
∠7 + 44 + 47 = 180
∠7 = 180 - 91
∠7 = 89

y = n^2 +nupper left corresponds to n^2; lower right corresponds to nStep-by-step explanation:
The number of squares in the upper left portion of the figure is the number in a square n on a side, so is n^2. The number of squares in the lower right portion of the figure is equal to the step number, n. A suitable equation adds these numbers together.
y = n^2 +n . . . . where y is the number of squares in the pattern of Step n.
Answer:Your answer is...
Step-by-step explanation:
y = n^2 +n

At the beginning of the semester, a professor tells students that if they study for the tests, then there is a 55% chance they will get a B or higher on the tests. If they do not study, there is a 20% chance that they will get a B or higher on the tests. The professor knows from prior surveys that 60% of students study for the tests. The probabilities are displayed in the tree diagram.
A tree diagram. Random student studies for test is 0.6, and does not study for test is 0.4. Studies for test to Gets B or higher is 0.55; does not get B or higher is 0.45. Does not study for test to Gets B or higher is 0.20; does not get B or higher is 0.80.
The professor informs the class that there will be a test next week. What is the probability that a randomly selected student passes the test with a B or higher?

1.Encuentra de dos formas diferentes el área de las figuras mostradas en cada literal:
Answer:
Cuadrilátero A: [tex]A = y^{2}+4\cdot y +4[/tex]
Cuadrilátero B: [tex]A = a^{2}+6\cdot a + 9[/tex]
Step-by-step explanation:
Existen dos formas distintas de determinar las áreas de cada cuadrilátero:
(i) Obtener el área de cada cuadrado y sumar los resultados.
(ii) Calcular los lados del cuadrilátero grande y determinar el área.
Cuadrilátero A
Método (i)
[tex]A = y^{2}+2\cdot y +4+2\cdot y[/tex]
[tex]A = y^{2}+4\cdot y +4[/tex]
Método (ii)
[tex]A = (y+2)\cdot (y+2)[/tex]
[tex]A = y^{2}+4\cdot y + 4[/tex]
Cuadrilátero B
Método (i)
[tex]A = a^{2}+3\cdot a +9 + 3\cdot a[/tex]
[tex]A = a^{2}+6\cdot a +9[/tex]
Método (ii)
[tex]A = (a+3)\cdot (a+3)[/tex]
[tex]A = a^{2}+6\cdot a + 9[/tex]
