$10.\\1ft=0.3048m\to1m=\dfrac{10000}{3048}ft\approx3.281ft\\\\therefore\ 14m\approx14\cdot3.28ft1=45.93ft$

$13.\\1mi=1.609km\to1km=\dfrac{1000}{1609}mi\approx0.621mi\\\\therefore\ 0.3km\approx0.3\cdot0.621mi=0.186mi$

$1in=2.54cm\to1cm=\dfrac{100}{254}in\approx0.394in\\\\therefore\ 15cm\approx15\cdot0.394in=5.91in$

Answer:

x=17

Step-by-step explanation:

well the triangles are congruent so that equation has to equal 61, so set it equal to 61, once you do that subtract 10 with 61 giving you 51, then divide 3 with 51 and you get 17

$3x + 10 = 61 \\ 3x = 51 \\ x = 17$

NEED HELP ASAP PLEASE WITH #7!!

AnnZ [28]

Answer:

The answer to your question is: The second option

Step-by-step explanation:

Points A (3 , 7) B (5, 11)

slope = m = (y2 - y1) / (x2 - x1)

m = (11 - 7) / (5 - 3)

m = 4 / 2 = 2

equation if the line

(y - y1) = m(x - x1)

(y - 7) = 2(x - 3) Answer

Explain how you got the answer

Gnoma [55]

Answer:

$\huge\boxed{Center = (3,3),Radius = 2\sqrt{15} }$

Step-by-step explanation:

<u><em>Given equation is</em></u>

$x^2 + y^2 -6x-6y -42 = 0$

Adding 42 to both sides

$x^2 + y^2 -6x-6y = 42\\$

Completing squares

$x^2 -6x+y^2 -6x = 42\\(x)^2 - 2(x)(3) +y^2 - 2(y)(3) = 42$

Adding (3)² => 9 and (3)² => 9 to both sides

$(x-3)^2+(y-3)^2 = 42+9+9\\(x-3)^2 + (y-3)^2 = 60\\(x-3)^2 (y-3)^2 = (2{\sqrt{15})^2}$

Comparing it with $(x-h)^2+(y-k)^2 = r^2$ where Center = (h,k) and Radius = r

We get:

Center = (3,3)

Radius = $2\sqrt{15}$
