A circle with area 9 pi, has sector with central angle of 17/9 pi radians
mr_godi [17]

Answer:

The area of the sector is 17/2 π

Step-by-step explanation:

pi = π

To solve this problem we first have to find the fraction that corresponds to this angle of the total, for this we must divide the angle that they give us by 2π radians, since that is the angle of a circle

(17π/9 rad) / (2π rad) = 17/18

Now we multiply the area of ​​the circle by this fraction and we will obtain the area of ​​the sector that we want

9π * 17/18 = 17/2 π

The area of the sector is 17/2 π

Jessica and Josh are selling Entertainment Books to raise money for the art room at their school. Jessica received the prize for
Over [174]

Answer:

Josh sold 16 books and Jessica sold 240 books

Step-by-step explanation:

Given: Jessica sold 15 times more books than Josh.

           Together they sold 256 books

To Find : How many did each one of them sell?

Solution:

Let Jessica sold x books

Let Josh sold y books.

Since we are given that Jessica sold 15 times more books than Josh.

⇒x=15y --a

We are also given that  Together they sold 256 books.

⇒x+y=256 --b

Using substitution method

Put value of x from equation a in equation b

⇒15y+y=256

⇒16y=256

⇒y=\frac{256}{16}

⇒y=16

Thus Josh sold 16 books

Jessica sold books = 15y = 15*16=240

Hence  Josh sold 16 books and Jessica sold 240 books
