  3.  2x

Step-by-step explanation:

The side ratios of a 30-60-90 triangle are in the ratios ...

  1 : √ : 2

The longest side is 2 times the length of the shortest side. If the shortest side is x, the longest side is 2x.

Answer:

248

Step-by-step explanation:

top and bottom are 4*10= 40 each

left and right 6*4= 24 each

front and back 10*6= 60 each

40+40+24+24+60+60=248

Answer:

x = 4

Step-by-step explanation:

subtract 5 from all sides

20x+5-5=5x+65-5

simplify

20x=5x+60

subtract 5x from both sides

20x-5x=5x+60-5x

simplify again

15x=60

Divide both sides by 15

15x/5 = 60/15

lastly simplify to get your answer of

x = 4

C. [tex] 9\pi [/tex]

Step-by-step explanation:

VU is tangent [tex] \odot W[/tex] at point U and WU is radius.

[tex] \therefore WU \perp VU[/tex]

[tex] \implies m\angle VUW=90\degree[/tex]

[tex] \therefore \triangle VUW[/tex] is right angle triangle.

WZ = WU = x - 1 (Radii of same circle)

WV = x - 1 + 2 = x + 1

By Pythagoras Theorem:

[tex] WU^2 + VU^2 = WV^2 [/tex]

[tex] (x-1)^2 +(2x-4) ^2 = (x+1)^2 [/tex]

[tex]x^2 -2x +1+ 4x^2 -16x + 16=x^2 +2x +1[/tex]

[tex]4x^2 -20x + 16=0[/tex]

[tex]x^2 -5x + 4=0[/tex]

[tex]x^2 -5x + 4=0[/tex]

Equating it with

[tex]ax^2 +bx +c=0[/tex]

We find:

a = 1, b = - 5, c = 4

[tex] b^2 - 4ac =(-5)^2 - 4(1)(4)= 25-16 =9[/tex]

[tex] x=\frac{-b\pm \sqrt{b^2 - 4ac}}{2a} [/tex]

[tex] x=\frac{-(-5)\pm \sqrt{9}}{2\times 1} [/tex]

[tex] x=\frac{5\pm 3}{2} [/tex]

[tex] x=\frac{5+3}{2}, \: x =\frac{5-3}{2} [/tex]

[tex] x=\frac{8}{2}, \: x =\frac{2}{2} [/tex]

[tex] x=4, \: x =1 [/tex]

When x = 4, radius (r) = 4 - 1 = 3

When x = 1, radius (r) = 1 - 1 = 0, which is not possible.

Area of [tex] \odot W [/tex]

[tex] =\pi r^2 [/tex]

[tex] =\pi (3)^2 [/tex]

[tex] =9\pi [/tex]

Answer:

-21

Step-by-step explanation:

the formula for the perimeter of a rectangle is 2l+2w. which means twice the length and twice the width added to together.

if you mean this:

x=21+2x

minus x on both sides

0=21-x

add 21 on both sides

21=-x

x=-21

than you subsitute

2×-21=-42

-42+21= -21

The perimeter is than -21

Answer:

Y = (-1/8) X + C is the equation of a line parallel to y=8-1/8x

Step-by-step explanation:

Complete question.

Find the line parallel to y=8-1/8x

Solution

For two lines to be parallel to each other it is essential that their slopes must be same

For any line of the form

Y = mX +b

m is the slope

Here the equation of given line is  y=8-1/8x

on rearranging, we get

Y = (-1/8) X + 8

here m = (-1/8)

Hence, line parallel to y=8-1/8x is any line with slope equal to (-1/8)

Or we can say that equation of parallel line would be

Y = (-1/8) X + C

Answer: x=48

Step-by-step explanation:

The length AC of the right-angle triangle will be 48 units.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

According to the hypotenuse-leg (HL) principle, a right triangle is harmonious if each of its third side and legs are congruent with its equivalent hypotenuse and legs in another right triangle. The HL theorem proves that these triangles are identical.

AC / AB = AB / AD

AC / 24 = 24 / 12

AC = 48 units

The length AC of the right-angle triangle will be 48 units.

Answer:

Sides of the rectangular area:

x =  30  f

y =  33  f

Step-by-step explanation:

Let´s call   x  and y the sides of the rectangular area

A = x*y  = 990          y  = 990/x

The function cost is:

C = Costs ( sides x)  + costs ( sides y )

Cost of sides x    =  12*x +  10x

Cost of sides y    =  10*y  +  10 *y   =  2*10*y  = 20*y

C = 12*x + 10*x + 20*y =  22*x  + 20*y

The function cost as function of x is:

C(x)  = 22*x + 20*(990/y)  =  22*x  +  19800/x

Tacking derivative on both sides of the equation:

C´(x)  = 22  + [ - 19800/x²]

C´(x) = 0       22  - 19800/x²  =  0

Solving for x

22*x²  - 19800  =  0

22x²  =  19800

x² =  19800/22 =  900

x₁,₂ = ± 30        We dismiss negative root ( we never have negative lenghts)

Then     x =  30 f

And  y  =  990 / 30      y  = 33  

To see if x = 30 is a minimum for function C(x) we evaluate the second derivative.

C´´(x) = 2*x* 19800/x⁴      

C´´ (x) = 39600/x³    so C´´ is always greater than 0 then C (x) has a minimum at x = 30

Sides of the rectangular area are:

x  =  30

y  =  33
