There are 6 bookshelf's that hold 72 books per shelf. if 1/3 of the total number of books are non-fiction,how many fiction books
Karolina [17]

Answer:

288 fiction books

Step-by-step explanation:

If the other 2/3 are fiction, then I believe that you would multiply 72 by 6 then divide by 3 or multiply by 1/3 giving you 144. Multiply 144 by 2 and you should get 288, but this is if there are only fiction and non fiction. Sorry if this is wrong..

Sketch the region bounded by the curves, and visually estimate the location of the centroid. y = 2x, y = 0, x = 1 WebAssign Plot
ASHA 777 [7]

Answer:

the graph is in the attachment.

the coordinates of the centroid : (2/3,2/3)

Step-by-step explanation:

  • y=0 represents x-axis ( you can easily mark it on the graph)
  • now draw x=1 line.( It is a line parallel to y axis and passing through the point (1,0) )
  • y=2x is a line which passes through origin and has a slope "2"

by using these sketch the region.

I have uploaded the region bounded in the attachment. You may refer it. The region shaded with grey is the required region.

  • to find centroid:

it can be easily identified that the formed region is a triangle

  • the coordinates of three vertices of the triangle are

(1,2) , (0,0) , (1,0)

( See the graph. the three intersection points of the lines are the three vertices of the triangle)

  • for general FORMULA, let the coordinates of three vertices of a triangle PQR be P(a,b) , Q(c,d) , R(e,f)
  • then the coordinates of the centroid( let say , G) of the triangle is given by

G = (\frac{a+c+e}{3}  , \frac{b+d+f}{3} )

  • therefore , the exact coordinates of the centroid =

(\frac{1+0+1}{3}, \frac{2+0+0}{3}  ) = (\frac{2}{3}, \frac{2}{3} )

this point is marked as G in the graph uploaded.

Will mark brainliest if you answer
mr_godi [17]

Answer:

10 square in.

Step-by-step explanation:

The rectangles are similar by a scale factor of 3. We can tell because the quotient of two of the corresponding sides, 18 and 6, is 3 (18/6=3)

That means the width of ABCD is 3 times the width of WXYZ.

Let's say the width of ABCD is x. Then 18*x=90 because that's the area.

x=90/18=5

Now we have the width of ABCD, 5, so to get the width of WXYZ, we divide by 3, which is 5/3.

Now to get the area of WXYZ, we can do 5/3, the width, times 6, the length, which is 30/3=10.
