Three whole numbers are each rounded to the nearest 10. The sum of the rounded numbers is 70.  Work out the maximum possible sum for the original three numbers.Sum of rounded numbers is 70, rounded number...

Law of indices : Rule: a^m * a^n = a^m+nTo multiply expressions with the same base, copy the base and add the indices. Lets start with gathering the a's - a^3 and a^2 adding the indices gets a^5Now b's - ...

Resolve forces perpendicular to the slope. No acceleration in this direction hence resultant force in this direction must equal zero:R = mg * cos(30) Apply Newtons second law in the direction parallel to ...
