Answer:

Step-by-step explanation:

Call the given fraction x

x = 0.436363636....

Multiply the given fraction by 1000

1000 x = 436.3636363636 ....

10 x = 4.363636.... is the original number multiplied by 10

990x = 432 the 0.36363636 ... cancels out of both of them

990x = 432 Divide by 990

x = 432 / 990

x = 216 / 495

I think that is about as simple as you can get it.

Solve and check 0.18(5x – 4) = 0.5x + 0.8

stiv31 [10]

Answer:

3.8

Step-by-step explanation:

0.18(5x – 4) = 0.5x + 0.8
0.9x - 0.72= 0.5x +0.8
0.9x- 0.5x= 0.8+0.72
0.4x= 1.52
x= 1.52/0.4
x= 3.8

----------

0.18(5*3.8 - 4)= 0.5*3.8 + 0.8
0.18*15= 1.9 + 0.8
2.7=2.7

In geometry, Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a triangle by

uysha [10]

Answer:

C) $6.495\: ft^2$

Step-by-step explanation:

a = 7 ft, b = 3 ft, c = 5 ft (Given)

Therefore, a + b + c = 7 + 3 + 5 = 15 ft

Let's calculate semi Perimeter of the triangle which is given by s

$s =\frac{a+b+c}{2}=\frac{15}{2} = 7.5 \: ft$

Now, by Heron's formula, area of triangle ABC is given as:

$A(\triangle ABC) =\sqrt{s(s-a) (s-b)(s-c)}$

$\therefore A(\triangle ABC) =\sqrt{7.5(7.5-7) (7.5-3)(7.5-5)}$

$\therefore A(\triangle ABC) =\sqrt{7.5(0.5) (4.5)(2.5)}$

$\therefore A(\triangle ABC) =\sqrt{42.1875}$

$\therefore A(\triangle ABC) =6.49519053$

$\therefore A(\triangle ABC) =6.495\: ft^2$
