Two factory plants are making tv panels. Plant A produced 2000 fewer panels than Plan B did. Two percent of the panels from Plan
Serggg [28]

Answer:

Plant A produced 15,000 panels.

Step-by-step explanation:

Let plant B produce x panels

Plant A then produced x - 2000 panels

2% of panels from plant A were defective

3% of panels from plant B were defective

The two plants together produced 810 defective panels so;

2/100(x - 2000) + 3/100(x) = 810

0.02x - 40 + 0.03x = 810

0.05x = 850

x = 17,000 panels

So plant B produced 17,000 panels

Plant A produced 17,000 - 2,000 panels = 15,000 panels.

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AC =16 and DC=5 what is the length of BC in the simplest ra
Nana76 [90]

The length of BC is 4 \sqrt{5}.

Solution:

Given ABC is a right triangle.

AC is the hypotenuse and BD is the altitude.

AB and BC are legs of the triangle ABC.

AC = 16 and DC = 5

<u>Leg rule of geometric mean theorem:</u>

$\frac{\text { hypotenuse }}{\text { leg }}=\frac{\text { leg }}{\text { part }}$

$\Rightarrow \frac{AC}{BC}=\frac{BC}{DC}$

$\Rightarrow \frac{16}{x}=\frac{x}{5}$

Do cross multiplication.

\Rightarrow  16\times 5 = x\times x

\Rightarrow  80= x^2

\Rightarrow  16\times 5= x^2

Taking square root on both sides.

\Rightarrow  \sqrt{16\times 5} = \sqrt{x^2}

\Rightarrow  \sqrt{4^2\times 5} = \sqrt{x^2}

square and square roots get canceled, we get

\Rightarrow  4\sqrt{ 5} = x

The length of BC is 4 \sqrt{5}.
