a) Triângulo = 3 lados.
b) Quadrilátero = 4 lados.
c) Pentágono = 5 lados.
d) Hexágono = 6 lados.
e) Heptágono = 7 lados.
f) Octógono = 8 lados.
2) O ângulo reto, também conhecido como ângulo de um quarto de volta, mede: a) 90 °
3) O ângulo que mede menos 90 ° e mais que 0 ° é denominado: a) agudo
4) 2240
5) 5040 sinalizadores
6) Calcule: a) 861 x 27 = 23247
b) 798 x 45 = 35910
Step-by-step explanation:
1) Liste o nome dos polígonos de acordo com o número total de lados.
a) Triângulo = 3 lados.
b) Quadrilátero = 4 lados.
c) Pentágono = 5 lados.
d) Hexágono = 6 lados.
e) Heptágono = 7 lados.
f) Octógono = 8 lados.
2) O ângulo reto, também conhecido como ângulo de um quarto de volta, mede: a) 90 ° b) 180 ° c) 270 ° d) 360 °
= a) 90°
Um triângulo ângulo reto pode ser definido como um triângulo onde um de seus 3 ângulos é equivalente a 90 graus (90°).
3) O ângulo que mede menos 90 ° e mais que 0 ° é denominado: a ) agudo b) raso c) reto d) obtuso.
Um ângulo maior que 0 ° e menor que 90 ° pode ser definido como um ângulo agudo.
= a) agudo
4) Um teatro com 64 filas de assentos e cada fila tem 35 assentos. Qual é a capacidade deste teatro?
No teatro, cada fila tem 35 lugares.

The mean of on road accidents reported to the police for the days in December is 6.7
What is the meaning of mean ?In a group of numbers, the mean is the average or most common value. It is a measure of central tendency of a probability distribution along the median and mode in statistics.
It is given in the question about the information on road accidents reported to the police for the days in December.
Mid point of (0-5) = 2.5

What is a function?A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.
Given function:
f(x) = 4
To find the input value of x;
Let the function,
y = f(x)
4 = f(x)
That means, y = 4.
From the attached graph;
We interpreted two values
x = -1 and 9 where f(x) = 4
Therefore, -1 and 9 are the values.

a/12=5/6 solve for a
Answer:
a = 10
Step-by-step explanation:
Multiply both sides by 12
[tex]\frac{a}{12}[/tex] = [tex]\frac{5}{6}[/tex]
[tex]\frac{12a}{12}[/tex] which cancels out because it's 1
[tex]\frac{5 * 12}{6}[/tex] = [tex]\frac{60}{6}[/tex]
a = 10

Negative StartFraction 11 Over 2 EndFraction
Negative StartFraction 11 Over 8 EndFraction
StartFraction 11 Over 8 EndFraction
StartFraction 11 Over 4 EndFraction
Answer:
B. -11/8
Step-by-step explanation:
Given:
tan m = ½
tan n = -6
Required:
Exact value of tan(m + n)
Solution:
Find m and n:
[tex] tan (m) = \frac{1}{2} [/tex]
[tex] tan (m) = 0.5 [/tex]
[tex] m = tan^{-1}(0.5) [/tex]
m = 26° (approximated)
[tex] tan (n) = -6 [/tex]
[tex] n = tan^{-1}(-6) [/tex]
n = -80° = 280° (i.e. 360 - 80)
Exact value of tan(m + n) = tan(26 + 280)

Solution x = ?
Answer:
x = 144
Step-by-step explanation:
When a number is being divided by another number , it will be that number/the number that is dividing that number.
Equation:
x/-9 = -16
x = -16(-9)
x = 144
Write an equation of a line that passes through the point (5,1) and is parallel to the line y= (-3/5)x -3
Answer:
y = (-3/5)x + 4
Step-by-step explanation:
Parallel lines have the same slope.
So the slope to the other line would be -3/5 as well.
Slope-intercept form is y = mx + b where m is the slope.
So you substitute the slope in making it y = (-3/5)x+b.
To find b, the y-intercept, you have to plug in the point for y and x in it. So you use the point (5,1) for it. That would get to 1 = (-3/5)5 + b.
To simplify that, it would get to 1 = -3 + b
Then you add 3 on both sides getting to b = 4.
Then you substitute b in, getting y = (-3/5)x + 4.

An equation of a line that passes through the point (5,1) and is parallel to the given line is y=-3/5 x+4.
Given that, a line that passes through the point (5,1) and is parallel to the line y= (-3/5)x -3.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
We know that, the slope of a line parallel to given line is m1=m2
By comparing y= (-3/5)x -3 with y=mx+c, we get m= -3/5
So, the slope of parallel line is -3/5
Now, put m= -3/5 and (x, y)=(5, 1), that is
1=-3/5 (5)+c
c= 4
So, equation with m=-3/5 and c=4, we have y=-3/5 x+4
Therefore, an equation of a line that passes through the point (5,1) and is parallel to the given line is y=-3/5 x+4.

What is the domain of the radical function shown on the graph?
The domain is the set of all possible x inputs. The blue curve stretches on forever in both directions along the x axis. This means that we can plug in any x value we want, and get some y output. We don't have to worry about dividing by zero, or applying the square root of a negative number, so there are no restrictions on the domain. We can take the cube root of a negative number with no issues. For example, the cube root of -8 is -2.
