if you subtract 1/2 from a number and multiply the result by 1/2 you get 1/8. what is the number?? (pls provide steps)

Bas_tet [7]

Answer:

$Number\ is\ \frac{3}{4}$

Step-by-step explanation:

Let the number be x

Subtract 1/2 from x = (x - 1/2)

Multiply 1/2 to the result = 1/2(x - 1/2)

The result is 1/8

That is,

$\frac{1}{2}( x - \frac{1}{2}) = \frac{1}{8}\\\\( x - \frac{1}{2}) = \frac{1}{8}\times \frac{2}{1}\\\\(x-\frac{1}{2}) = \frac{1}{4}\\\\x = \frac{1}{4} + \frac{1}{2}\\\\x = \frac{3}{4}$

If T: (x, y) → (x - 3, y + 2), then T -1: (x,y) → _____.

tatyana61 [14]

Answer:

(x + 3, y - 2)

Step-by-step explanation:

we know that

The rule of the transformation T is equal to

T: pre-image → image

T: (x, y) → (x',y')

T: (x, y) → (x - 3, y + 2)

so

x'=x-3 ----> x=x'+3

y'=y+2 ----> y=y'-2

The rule of the inverse of transformation T -1 is equal to

T-1: image → pre-image

T-1: (x', y') → (x,y)

T-1: (x', y') → (x'+3, y'-2)

worty [1.4K]

Answer:

P = 15.71 cm

Step-by-step explanation:

Given that,

The diameter of the semicircle, d = 10 cm

Radius, r = 5 cm

The perimeter of the semicircle is given by :

$P=\dfrac{\text{The perimeter of the circle}}{2}\\\\=\dfrac{2\pi r}{2}\\\\=\pi r\\\\=3.142\times 5\\\\=15.71\ cm$

So, the perimeter of the semicircle is 15.71 cm.

Fofino [41]

Answer:

.943686485

Step-by-step explanation:

1=p(0)+p(1)+p(2)+p(3)+.....p(10)

1-p(0)=P(1)+p(2)+p(3)+....p(10)

or

1-p(0)= p(at least one)

p(0)=

${10\choose0}*.25^0*.75^{10}=.056313515$

1-.056313515=.943686485
