Let x equal the number we're trying to find.

Convert percent to decimal by moving the % sign to the left two times and replacing it with a decimal.

.40x = 56

Divide both sides by .40

x = 140

40%= 56
1%= 56/40= 1.4
100%= 1.4 x 100= 140

What is the answer??
AVprozaik [17]

Answer:

HK = 20

Step-by-step explanation:

LM = (1/2) HK          {Mid point theorem}

10x - 90 = \frac{1}{2}(10x - 80) \\

2*(10x - 90) = 10x - 80

2*10x - 2*90 = 10x - 80

20x - 180     = 10x - 80                   {add 180 to both sides}

           20x  = 10x - 80 + 180

          20x  = 10x +100              {Subtract 10x from both sides from }

     20x -10x = 100

            10x  = 100

                x = 100/10

               x = 10

HK = 10x - 80

     = 10*10 - 80

     = 100 - 80

     = 20

the formula for the area of a circle is \pi r^{2}

the diameter is 2 times the radius, so dividing it by 2 gives you a radius of 2

substitute the 2 for the r in the formula and solve

\pi 2^{2}
