Sharon is painting her house. she needs 5 gallons of brown paint for every 7 gallons of white paint.  How many gallons of white
Igoryamba

Answer:

19.6

Step-by-step explanation:

The ratio of brown paint to white paint is, 5:7 or \frac{5}{7} so if he bought 14 gallons of white paint we need to figure out:

\frac{5}{7} =\frac{14}{x}

which we can as it only has one unknown:

5x=14×7

5x=98

x=19.6

So the answer is 19.6

AlladinOne [14]

Answer:

Step-by-step explanation:

x(x-2y)-(y-x)2  

Final result :

 -y2

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 x • (x - 2y) -  (y - x)2

Step  2  :

2.1     Evaluate :  (y-x)2   =    y2-2xy+x2  

Final result :

 -y2

find the flux of the constant vector field v→=3i→ 2j→−5k→ through a square plate of area 25 in the xz-plane oriented in the posi
Readme [11.4K]

The flux across a surface is an indicator of the rate at which fluid is flowing through it when there is a fluid flowing in three dimensions and a surface positioned inside that space.

<h3>What is Electric Flux?</h3>
  • A feature of an electric field is electric flux. One way to conceptualize it is as the quantity of forces interacting in a specific space.
  • According to conventional wisdom, electric field lines begin with positive electric charges and conclude with negative charges.
  • A closed surface's field lines are seen as negative when they are directed into it, and as positive when they are directed out of it.
  • Every field line that is directed into a closed surface continues through the interior and is often directed outward somewhere else on the surface if there is no net charge present within the surface.
  • The net, or total, electric flux is zero because the size of the negative and positive fluxes are just about equal.
  • A closed surface that contains a net charge will have a total flux that is proportional to the enclosed charge, positive if it is positive and negative if it is negative.
