Direct variation means y=kx (inverse variation is yx=k or y=k/x)

so we are given that:

75=k/2, so k=150 which means:

y=150x  now

y(2.25)=150(2.25)=337.5

The diagonals of a square measure 14cm. Which is the length of a side of the square?
Sedaia [141]
The sides of a square have the same lengths, so the diagonal and two sides form a 45-45-90 right triangle. In a 45-45-90 triangle, the hypotenuse has a length with is \sqrt{2} longer than the legs.

Therefore, the sides of the square would be \frac{14}{ \sqrt{2} }.

Rationalize the fraction be multiplying the numerator and denominator by root 2.

\frac{14 \sqrt{2} }{2}

The 14 and 2 will reduce to 7, and the answer is A.
