Call x the distance from home plate to second base.
There is a right triangle formed by homeplate, first base and second base. The sides of this triangle are 80 feet and 80 feet. The hypothenuse meets Pythagoras theorem:
x^2 = 80^2 + 80^2 = 2(80)^2
x = 80√2
Then the answer is the option D.

The understanding one needs to work with percentages is:
1/100 = 1% = 0.01
Also
6/100 = 6% = 0.06
also
25/100=1/4=0.25=25%
To find a spesific share of a total, we can multiply the perectage with the total, like this: Total * 6% or in a way easier to work with: Total * 0.06 or (Total * 6)/100
If you have a calculator i would recommend using the decimals, as they are one of the easiest to type in - and remember once you get the hang of it.
To find the money Nina has saved, you do the following.
150*0.06=9$
Nina has saved 9 dollars.
The remaining percent she needs, is
100-6=94%
She still needs money for 94% of the bike.
