PLEASE HELP DUE SOON PLEASE !!

sukhopar [10]

Answer:

(1 + \sqrt{3} ) : 3

Step-by-step explanation:

AB = x $\sqrt{3} cm$

BC = x cm

Area = l * b = x $\sqrt{3}$ * x

= x^2 $\sqrt{3}$

EFG is equilateral triangle

EF = y cm

Area of triangle = $(\sqrt{3} / 4) * a^{2}$

A = (\sqrt{3} / 4) * y^{2}

As both areas are equal

$\sqrt{3} x^{2} = \sqrt{3} /4 * y^{2}$

$4x^{2} = y^{2}$

2x = y

perimeter of ABCD = 2 (l + b)

$2 (x\sqrt{3} + x)\\= 2x(\sqrt{3} + 1)$

perimeter of EFG = 3y

so ratio is $2x(\sqrt{3} + 1) : 3y$

substitute y = 2x

$2x(\sqrt{3} + 1) : 3*2x\\(\sqrt{3} + 1) : 3$

$(1 + \sqrt{3} ) : 3$

To the nearest tenth, find the perimeter of ∆ABC with vertices A(-1,4), B(-2,1) and C(2,1). Show your work.

frez [133]

Answer: $\bold{4+3\sqrt2+\sqrt{10}}$

<u>Step-by-step explanation:</u>

Perimeter is the sum of the lengths of the sides. Use the distance formula to find the lengths of each of the sides, then find their sum.

$d_{AB}=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}$

$=\sqrt{(-2+1)^2+(1-4)^2}$

$=\sqrt{(-1)^2+(-3)^2}$

$=\sqrt{1+9}$

$=\sqrt{10}$

$d_{AC}=\sqrt{(x_C-x_A)^2+(y_C-y_A)^2}$

$=\sqrt{(2+1)^2+(1-4)^2}$

$=\sqrt{(3)^2+(-3)^2}$

$=\sqrt{9+9}$

$=\sqrt{18}$

$=3\sqrt{2}$

$d_{BC}=\sqrt{(x_C-x_B)^2+(y_C-y_B)^2}$

$=\sqrt{(2+2)^2+(1-1)^2}$

$=\sqrt{(4)^2+(0)^2}$

$=\sqrt{16+0}$

$=\sqrt{16}$

$=4$

How do you solve this? Please show work so I can see how to do it!<br> <img src="https://tex.z-dn.net/?f=2%20%5Csqrt%5B3%5D%7B27

The answer is 6. You must divide 27 by the 3rd power which is three. then multiply by 2. If that's wrong you might divide by 2 making the answer 1.5

The scale of this map is 1 inch = 50 miles. The ruler measures the distance between Gary, Indiana, and Traverse City, Michigan,

levacccp [35]

Answer:

<em>150 miles</em>

Step-by-step explanation:

Given the scale on the map using the conversion factor

1 inch = 50 miles

We are to find the equivalent miles between the cities in miles if the distace is 3inches

3inches = x

Divide both expressions

1/3 = 50/x

Cross multiply

x = 3 * 50

x = 150

<em>Hence the actual distance between these two cities in miles is 150 miles </em>
