Two factory plants are making tv panels. yesterday, plant a produced 4000 fewer panels than plant b did. two percent of the panels from plant a and 4% of the panels from plant b were defective. how many panels did plant b produce, if the two plants together produced 700 defective panels?

Plant B produced  17000 panels.

Step-by-step explanation:

Two factory plants are making TV panels.

Yesterday, Plant A produced 3000 fewer panels than Plant B did.

Five percent of the panels from Plant A and 4% of the panels from Plant B were defective.

How many panels did Plant B produce, if the two plants together produced 1380 defective panels?

   A = B - 3000           (1)     ("Plant A produced 3000 fewer panels than Plant B did")

0.05A + 0.04*B = 1380.     (2)     (counting defective panels)

Substitute expression (1) into eq(2). You will get

0.05*(B-3000) + 0.04*B = 1380,

0.05*B - 150 + 0.04*B = 1380,

0.09*B = 1380 + 150 = 1530  >  B = 1530%2F0.09 = 17000.

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
