Select the option that represents the number of parallelograms in the given figure.

 

 

Technically or logically it is possible only once. As if you subtract 5 from 25 at first te result will be 20. Now, you can't subtract 5 from 25 since the left number is 20.

But if you go mathematically, it can be done infinite times and only 5 times without going into the negatives.

18 tens 20 ones, the given stateent can be split into

18 tens = 18 x 10 = 180

20 ones = 20 x 1 = 20

Then add both => 180 + 20 = 200

Hence, 18 tens 20 ones = 200.

The reciprocal of a negative number is always a negative number. So that the number and its reciprocal multiply to 1. 

All real numbers except 0 have reciprocals.

Points that lie on the same line are called Collinear points. And that points lie on the same plane are called Coplanar points. 

The distance around a circle is called as Circumference. And that in the case of square or rectangle it is called as Perimeter.

The process of collecting, organizing and analyzing data is called Statistics.

The worst case complexity of linear search is O(n).

The given statement about similar triangles is TRUE.
