Trevon spent 8 hours and 15 minutes at an amusement park yesterday he spent 75% of the time at the park about how much time did he spend on rides

Convert 8 hours and 15 minutes into minutes-   8 x 60=480 480+15=495
100%-75%=25%
25%=0.25
0.25 x 495  = 123.75 minutes or 2 hour and 3.75 minutes

Hope this helps!!

So 8 hours+15mins at park
park=75%
rides=100%-park=100-75=25%
HACK ALERT
25% is 1/4 so multiply 8 hours and 15 mins by 1/4 so
8 h and 15 mins times 1/4=8h times 1/4+15mins times 1/4=2h+3.75min=

2 hours and 3.75 mins spent on rides

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
