What is the multiplication inverse of 1/2
vitfil [10]

Answer:

multiplicative inverse of 1/2 is 2

Step-by-step explanation:

The multiplicative inverse of a/b is b/a

Because \frac{a}{b} * \frac{b}{a} =1

To get multiplicative inverse of any fraction we take the reciprocal of that fraction

Multiplicative inverse of  \frac{1}{2} \ is \ \frac{2}{1}

2/1 or 2  are same

so multiplicative inverse of 1/2 is 2

What are the center and radius of the circle defined by the equation ?
RUDIKE [14]
You didn't give us the equation, but circle equations are in the form;
(x-h)^2 + (y-k)^2 =r^2 where h and k are the x and y coordinate of the center and r is the radius of the circle squared.

Please help me with the question please ASAP

Answer:

The ratio of perimeter of ABCD to perimeter of WXYZ = \frac{2}{3}

Step-by-step explanation:

First, we have to determine the multiplicative factor of the dimensions for both figures.

Considering sides AB and WX,

multiplicative factor = \frac{12}{8}

                                = 1.5

So that:

XY = 6 x 1.5 = 9

YZ = 7 x 1.5 = 10.5

ZW = 7 x 1.5 = 10.5

Perimeter of ABCD = 6 + 7 + 7 + 8

                                = 28

Perimeter of WXYZ = 9 + 10.5 + 10.5 + 12

                                 = 42

The ratio of the perimeters of the two quadrilaterals can be determined as;

ratio = \frac{perimeter of ABCD}{Perirmeter of WXYZ}

       = \frac{28}{42}

       = \frac{2}{3}

The ratio of the perimeter of ABCD to perimeter of WXYZ is \frac{2}{3}.
