Answer
Find out the how many sports trophies does Amy have .
To prove
Let us assume that the number of sports trophies Amy have be x.
As given
Amy has two rows of 4 sports trophies on each of her three shelves.
Than the equation becomes
x = 2 × 4 × 3
simply multiply the above terms
x = 24
Therefore there are 24 sports trophies Amy have .
Let if you earn $100 per hour a raise of 2.5% means you will get $102.5.
i.e 102.5% of earlier.
in case of $6, it will be its 102.5%, = 102.5*6/100 = $6.15 per hour.
Its a right angled triangle. You have C and have B all you need to find is A. usually for a question like this you would use the Pythagorean theorem which is A2+B2=C2 but since we already have c we will use C2-B2=A2
Now we fill in the values. (21)2-(9)2=A2
441-81=360^2 so now with the 360^2 we have to squareroot it so the square root of 360 is 18.973f
