Answer:
5 miles.
Step-by-step explanation:
We would be using the Pythagoras Theorem to solve for this.
I have attached a diagram to better help you to better understand my explanation this.
The shortest distance from her playground to her house = Hypotenuse
Pythagoras Theorem for a triangle =
c² = a² + b²
Where c = Hypotenuse
a = 3 miles due west
b = 4 miles north
c² = 3² + 4²
c² = 9 + 16
c² = 25
c = √25
c = 5 miles
Therefore, the shortest distance to Alicia's home from the playground is 5 miles.
It would be (5x)(5x). Hope it helps!
It would be: 39/40 * 100 = 3900/40 = 97.5%
Hope this helps explain a little better
