Answer:

It gives you 28 different 10-digit numbers

Step-by-step explanation:

The leftmost position digit can not be 0 --- hence, it is 1, since there is no other possibilities.

The rightmost position (the "ones" position) must be 0 to provide an even number.

Hence, you have 8 remaining positions to fill with six ones and two zeros by an arbitrary way.

You can place two digits of zero among 8 positions by \frac{C 2}{8} = \frac{8=7}{2}different ways = 4*7 = 28 different ways,

Please help if you can ik it is Pythagorean theorem
kicyunya [14]

Step-by-step explanation:

A = (1/2)bh ---> h = 2A/b = 2(12 cm^2)/(5 cm) = 4.80 cm

---> x^2 = h^2 + (b/2)^2

= (4.8 cm)^2 + (2.5)^2

= 23.04 cm^2 + 6.25 cm^2

or x = 5.41 cm

Therefore, the perimeter P is

P = 2x + b = 2(5.41 cm) + 5 cm = 15.8 cm
