Step-by-step explanation:
(Area of total floor) - (area of rug) = area of exposed wood.
(19ft x 15ft) - (pi r^2)=
(285) - [pi (4.5)^2]= 221.38 square feet
221.4 square feet
Step-by-step explanation:
After the movie, the family can spend 6 hours in Millersville.
36+4h=60
36+4h-36=60-36
4h=24
4h÷4=24÷4
h=6
So, after the move they can spend 6 hours there. (6×4=24, 24+36=60, they will spend $60 if they spend 6 hours there, $56 if they spend 5 hours there and don't want to spend $60).
