The answer is 90%. You get this answer by multiplying both the numerator and denominator by 5 so 18x5=90 and 20x5=100 giving you a fraction of 90/100 and a percentage of 90%.

Please help being timed!!! Given: △ABC AB=BC=AC Area of △ABC= 25 3 4 cm2 Find: The perimeter

nirvana33 [79]

Answer:

15 cm

Step-by-step explanation:

The area of an equilateral triangle is:

$\frac{\sqrt{3} }{4}a^2$ , where a is the length of one side.

We can find the value of a (the length) by:

$\frac{25\sqrt{3} }{4} = \frac{\sqrt{3} }{4}a^2$

$a^2 = 25$

a = 5, so the side length of this triangle is 5 cm.

The perimeter of an equilateral triangle will be 3 times the length.

$3\cdot5=15$

Hope this helped!

Answer:

Step-by-step explanation:

Put the equation in the form ax+by+c=0:

$y\sqrt{3} =8x+\sqrt{3} \\=>8x-\sqrt{3} y+\sqrt{3} =0$

Check the solutions:

$(0,-1)$ :

$8(0)-\sqrt{3} (-1)+\sqrt{3} =2\sqrt{3}$

So this is not a solution.

( $(\sqrt{3} ,9)$ :

$8\sqrt{3} -9\sqrt{3} +\sqrt{3} =0$

So this is a solution
