Answer:

x = 13

Step-by-step explanation:

Given

See attachment

Required

Find x

From the attachment, we have:

BC = x + 4

BD = 2x - 7

GE = 51

GF = 57

Because both triangles are similar, we use the following equivalent ratios:

BC : BD = GE : GF

Substitute values for each parameter

x + 4 : 2x- 7 = 51 : 57

Convert to fractions

\frac{x + 4}{2x- 7} = \frac{51 }{ 57}

Simplify the right-hand side

\frac{x + 4}{2x- 7} = \frac{17}{19}

Cross Multiply

19(x + 4) = 17(2x - 7)

19x + 76 = 34x - 119

Collect Like Terms

19x - 34x = -76 - 119

-15x = -195

Solve for x

x = \frac{-195}{-15}

x = 13

PLEASE HELP ASAP AND THANKS Find x

Answer:

The value of x is 2.

Step-by-step explanation:

First, you have to make the left side into 1 fraction by making the denorminator the same :

\frac{x}{x - 2}  +  \frac{1}{5}

=  \frac{5x}{5(x - 2)}  +  \frac{x - 2}{5(x - 2)}

=  \frac{5x + x - 2}{5(x - 2)}

=  \frac{6x - 2}{5(x - 2)}

Then you have to do cross multiplication :

\frac{6x - 2}{5(x - 2)}  =  \frac{2}{x - 2}

(6x - 2)(x - 2) = 5(2)(x - 2)

6 {x}^{2}  - 12x - 2x + 4 = 10x - 20

6 {x}^{2}  - 14x + 4 = 10x - 20

6 {x}^{2}  - 14x + 4 - 10x + 20 = 0

6 {x}^{2}  - 24x + 24 = 0

6( {x}^{2}  - 4x + 4) = 0

{x}^{2} - 4x + 4 = 0

{x}^{2} - 2x - 2x + 4 = 0

x(x - 2) - 2(x - 2) = 0

(x - 2)(x - 2) = 0

x = 2

Circumference, radius, slant height, lateral area, and surface area are measurements of a cone. Given two of the measurements, f
USPshnik [31]

Answer:

  1. LA = 21.7 ft²; C = 18.8 ft; h = 2.3 ft
  2. h = 8 in; r = 7 in; SA = 330.1 in²

Step-by-step explanation:

Applicable relations are ...

  C = 2πr . . . . . . . r = radius, C = circumference

  LA = 1/2·Ch . . . . h = slant height, LA = lateral area

  SA = πr² +LA . . . SA = total surface area

__

1. Given r and SA, we can find the other measures as ...

  LA = SA -πr² = 50 ft² -π(3 ft)² ≈ 21.7 ft²

  C = 2πr = 2π(3 ft) ≈ 18.8 ft

  h = 2·LA/C ≈ 2·21.7 ft²/(18.8 ft) ≈ 2.3 ft

(Please note that for calculations using intermediate results, we used the full-precision values of those results, not the rounded ones. Rounding is always the last operation. Please note, too, that we have used a value for π sufficient to ensure accuracy in all the digits shown here.)

__

2. Given C and LA, we can find the other measures as ...

  h = 2·LA/C = 2(176 in²)/(44 in) = 8 in

  r = C/(2π) = (44 in)/(2π) ≈ 7.0 in

  SA = LA +πr² = LA +rC/2 ≈ 176 in² +(7.0 in)(44 in)/2 ≈ 330.1 in²
