Answer:
= 8.5 hours
= 8 hours 30 minutes
Step-by-step explanation:
Full time spent = 100%
If 40% = 3.4 hours ,
What about 100% = ?
= (100 x 3.4) ÷ 40
= 340 ÷ 40
Marvin spent 10 hrs 12 min at the recreational center.
or 10.2 hrs
3.4 hrs = 40% of x
3.4*2 = 80% of x
6.8 = 80% of x
6.8 + (1/2 * 6.8) = 100%
6.8 + 3.4 = 100%
10.2 = 100%
Volume of a sphere = 4/3πr³
π = 3.14
r = radius which is 3in
Volume = 4/3 × 3.14 × 3²
= 37.68
= 38 cubic inches to the nearest hundredth
Hope this helps
