We are told that the children from a football club are put into rows in the sports hall. When put into rows of 9 children there are 2 children left over. When put into rows of 12 children there are 2 children left over.
We will find least number of children in football club by finding LCM of 9 and 12.
Multiples of 9 are: 9, 18, 27, 36, 45, 54, 63,...
Multiples of 12 are: 12, 24, 36, 48, 60, 72, 84,...
We can see that least common multiple of 9 and 12 is 36.
We are told that 2 children left over from putting them into 9 and 12 children per row. To find least number we will add 2 to 36.
Therefore, the least number of children in the football club is 38.
Answer:
Step-by-step explanation:
Given : One nanometer equals about 0.00000004 inches.
To find : When writing this decimal as a single-digit integer multiplied by a power of ten, the single digit integer is and the power of ten ?
Solution :
Therefore, the decimal as a single-digit integer multiplied by a power of ten is
gg easy
the legs of a triangle are related as wehre a, b, and c are the legs and the hypotonuse of a triangle respectively
let's find some stuff
one easy way is to find a rational value for c find values of a and b
lets pick c=5
now split up 25 into 2 things that don't have rational square roots
if we say and
then we get
and
(which are both irrational)
