A regular polygon has an interior angle of 171 degrees. Show your work. (3 points for work, 3 points
for correct answers)
a) How many sides does it have?
b) What is the sum of the interior angles?
c) What is the measure of one of its exterior angles?
Answer:
a) 40 sides
b) 6840
c) 9 gegrees
Step-by-step explanation:
interior angle= (n-2)180
n
[tex] (n - 2)180 \div n = 171 \\ 180n - 360 = 171n \\ 180n - 171n = 360 \\ 9n = 360 \\ n = 360 \div 9 = 40 \\ [/tex]
so total number of sides is 40
b) Sum of interior angles= (n-2)×180
(40-2)×180
38×180
6840
c) Exterior angle = 360 ÷ n
360÷40 =9 degree
Tengo que leerme un libro de 1267 páginas en 3 semanas. La primera semana he leído 189 páginas y la segunda el triple que en la primera, ¿cuántas páginas me quedan por leer en la tercera semana?
Answer:
Quedan 511 páginas por leer en la tercera semana.
Step-by-step explanation:
Si el libro tiene 1267 y debe leerse en 3 semanas, se ha leído 189 páginas en la primera semana y 567 páginas en la segunda semana, es decir, el triple del número de páginas leídas en la semana anterior, la cantidad de páginas por leer para la tercera se determina mediante la siguiente sustracción:
[tex]x = 1267 - 189 - 567[/tex]
[tex]x = 511[/tex]
Quedan 511 páginas por leer en la tercera semana.
Bao owns a small business selling used books. She knows that in the last week 20
customers paid cash, 26 customers used a debit card, and 13 customers used a credit
card.
Based on these results, express the probability that the next customer will pay with a
debit card as a percent to the nearest whole number.
Answer:
44% cahnce
Step-by-step explanation:
To solve this, add up all the customers. Then, divide the amount of debit card customers, by the total amount of customers. This will give you percentage of people who paid in debit, which is also the probability:
20+26+13
=
59
This is the amount of customers. Now we divide:
26/59
=
0.4406
Remember that to create percentage, you must multiply the decimal by 100:
0.4406*100
=
44.06%
The .06 is so small that it doesnt need to be kept in this percentage:
44%
So this is you answer!
Hope it helps! :)

what is the length for the 3rd side? write in simplest radical form if needed
Answer:
10
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
Let the third side be x , then
x² + 6² = (2[tex]\sqrt{34}[/tex] )²
x² + 36 = 136 ( subtract 36 from both sides )
x² = 100 ( take the square root of both sides )
x = [tex]\sqrt{100}[/tex] = 10

Answer:
Given
F ( x ) = 3 x 2 + 1 , to find F ( − 2 ) , we have to just put
x = − 2 in the formula for F ( x ) .
therefore , F ( − 2 ) = 3 ( − 2 ) 2 + 1 = 3 ( 4 ) + 1 = 13 .

If y varies directly as x and y = 64 when x = 16, what is the value of y when x = 12 ?
Answer: Y=48
Y is 4 times more than x. If x=12, y=48. Notice in the first part of the question, if you divide 64 by 4, you get 16. This means in order to get your answer, you must mulitiply x by 4 to get y. 12x4=48.

Which shows how to determine the volume of the pyramid?
Answer:
d would be correct
Step-by-step explanation:
A pyramid is a polyhedron formed by connecting a polygonal base and an a a p e x. The basic formula for pyramid volume is the same as for a cone: volume = (1/3) times base area times height, where height is the height from the base to the a p e x. That formula is working for any type of base polygon and oblique and right pyramids.

Find the circumference of the circle. Use 3.14 !! (No link)
Answer:
62.8 ft
Step-by-step explanation:
Given,
Diameter = 20 ft ( from the diagram )
pi = 3.14
To find : Circumference ( circle ) = ?
Radius ( r )
= Diameter / 2
= 20 / 2
= 10 ft
Formula : -
Circumference ( circle ) = 2 pi r
Circumference ( circle )
= 2 x 3.14 x 10
= 2 x 31.4
= 62.8 ft
The solution to the system is (3,4):
3x – 2y = 1
4y = 7+3x
Pizz help mee
Answer:
(3,4) is the solution of both equations.
Step-by-step explanation:
The given equations are :
3x – 2y = 1 ....(1)
4y = 7+3x
4y-3x = 7 .....(2)
Put x = 3 and y = 4 in equation (1).
3(3) – 2(4) = 9-8
= 1
So, (3,4) is the solution of the equation (1).
Again put x = 3 and y = 4 in equation (2).
4(4)-3(3) = 16-9
= 7
Hence, (3,4) is the solution of both equations.

Answer:
It is an isosceles triangle.
Step-by-step explanation:
sum of angles of triangle = 180
since it is isosceles two angles will be same. let it be x.
x + x + 22 = 180
2x = 180 - 22
2x = 158
x = 79°
I know the answer can someone just help me explain it???
Step-by-step explanation:
It is Graph B. We can do this by checking the points. The equation given is d = 5t^2, where d technically is the y-coordinate and t is the x-coordinate. On Graph B, two obvious points are (1, 5) and (2, 20). We can check these points to see if they fit the equation.
(1,5): d = 5t^2
5 = 5(1)^2
5 = 5*1
5 = 5, so this point is correct.
(2, 20): = d = 5t^2
20 = 5(2)^2
20 = 5*4
20 = 20, so this point is correct.
We know that Graph A is incorrect because it doesn't follow the equation. The line goes through (1, 5), which we already know is correct, (2, 10), (3, 15), and (4, 20). We already figured out that (2, 20) is correct so (2,10) can't be correct. (3, 15) and (4, 20) are also incorrect but in this case, we only need to find one incorrect coordinate to validate our answer. Thus, as Graph A is wrong, Graph B is right.

What is the volume (V) of the cylinder shown below ? Use 3.14 for π .
The volume (V) of the given cylinder with the height 10 mm and the diameter 14 mm is 1538.6 cubic millimeter.
From the given figure, diameter of a cylinder = 14 mm and height = 10 mm.
Here, radius = [tex]\frac{14}{2}[/tex]
= 7 mm
Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
We know that, the formula to find the volume of a cylinder is [tex]\pi r^2h[/tex].
Here, the volume of a cylinder = 3.14×7²×10
= 3.14×49×10
= 1538.6 cubic millimeter
Therefore, the volume (V) of the given cylinder with the height 10 mm and the diameter 14 mm is 1538.6 cubic millimeter.
