The fraction will reduce to 1/4  . 7 goes into 28  4 times so the bottom number is 4 . So the top is divided by 7 so it is 1

Someone plz help to become brainliest and get points !! :) plz answer truthfully
Ilia_Sergeevich [38]

Total number of cubic inches of cheese sauce in container = Volume of cylinder = \pi .8^2.7

Option A is correct.

Step-by-step explanation:

The diameter of cylinder = 16 inches

The height of cylinder = 7 inches

Total number of cubic inches of cheese sauce in container = Volume of cylinder = ?

The formula used to find Volume of cylinder is:

Volume=\pi r^2h

We are given diameter of cylinder while we need radius according to formula.

So, radius = diameter/2

radius = 16/2

radius = 8

Putting values and finding volume:

Volume=\pi .8^2.7

So, Total number of cubic inches of cheese sauce in container = Volume of cylinder = \pi .8^2.7

Option A is correct.

Solve for x and y:<br> 3/x -1/y =13/10<br> 1/x + 2/y =9/10
harkovskaia [24]

Answer:

  (x, y) = (2, 5)

Step-by-step explanation:

I find it easier to solve equations like this by solving for x' = 1/x and y' = 1/y. The equations then become ...

  3x' -y' = 13/10

  x' +2y' = 9/10

Adding twice the first equation to the second, we get ...

  2(3x' -y') +(x' +2y') = 2(13/10) +(9/10)

  7x' = 35/10 . . . . . . simplify

  x' = 5/10 = 1/2 . . . . divide by 7

Using the first equation to find y', we have ...

  y' = 3x' -13/10 = 3(5/10) -13/10 = 2/10 = 1/5

So, the solution is ...

  x = 1/x' = 1/(1/2) = 2

  y = 1/y' = 1/(1/5) = 5

  (x, y) = (2, 5)

_____

The attached graph shows the original equations. There are two points of intersection of the curves, one at (0, 0). Of course, both equations are undefined at that point, so each graph will have a "hole" there.
