Answer:
38
Step-by-step explanation:
Since Oliver ran 23 fewer laps, you would use subtraction.
So you do 61-23=38
Hope this helps!!
Let me know if you are confused.
Assuming right angle, root 10^2+12^2 and you get 2 root 61
Okay this equation really says is what is 30% of 248.
So, lets convert 30% to a fraction, 3/10 which is easier to work with.
All you have to do now is get out a calculator and do 248 *3/10 (or .3) and get 74.4
So subtract 74.4 and get
173.6
