Answer:

30% decrease

Step-by-step explanation:

We have to divide 39 by 130 and then find the percentage of it. 39/130 is equal to 3/10, and 3/10 is equal to 30%. That means that it was a 30% decrease.

Answer:

$\boxed{c = 5.7 units}$

Step-by-step explanation:

<u><em>Using Pythagorean Theorem:</em></u>

=> $c^2 = a^2+b^2$

Where c is hypotenuse, a is base and b is perpendicular and ( a, b = 4)

=> $c^2 = 16+16$

=> $c^2 = 32$
