A circle has a sector with area \dfrac{17}{2}\pi 2 17 πstart fraction, 17, divided by, 2, end fraction, pi and central angle of \purple{\dfrac{17}{9}\pi} 9 17 πstart color #9d38bd, start fraction, 17, divided by, 9, end fraction, pi, end color #9d38bd radians . What is the area of the circle?
Answer:
The area of the circle is equal to [tex]9\pi[/tex].
Step-by-step explanation:
Given that,
The area of sector is, [tex]\dfrac{17}{2}\pi[/tex]
The central angle is [tex]\dfrac{17}{9}\pi[/tex]
We need to find the area of circle.
We know that,
[tex]\text{Area of sector}=\dfrac{\text{central angle}}{2\pi}\times \text{Area of circle}\\\\\text{Area of circle}=\dfrac{2\pi \times \text{Area of sector}}{\text{central angle}}\\\\=\dfrac{2\pi \times \dfrac{17\pi}{2}}{\dfrac{17\pi }{9}}\\\\=9\pi[/tex]
So, the area of the circle is equal to [tex]9\pi[/tex].

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! :)

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.
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.
please help me out with this problem. will give thanks!
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°
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.

Plz hurry find the surface area and volume to the nearest whole number
Answer:
87.96 or 88 - surface area
62.83 or 63 - volume
Step-by-step explanation:
Answer:
Surface area: 89 yd
Volume = 63 yd
Step-by-step explanation:
Surface area:
A=2πrh+2πr^2
=2·π·2·5+2·π·2^2
=87.96459
Volume:
V=πr2h
=π·22·5
=62.83185

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.

1 is subtracted from the division of a number and 9. The result is -2.
Answer:
The number is - 9.
Step-by-step explanation:
(y ÷ 9) - 1 = - 2
(y ÷ 9) - 1 + 1 = - 2 + 1
y ÷ 9 = - 1
y ÷ 9 × 9 = - 1 × 9
y = - 9

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
