Answer:
a) 7 weeks b) George's
Step-by-step explanation:
Sally's score can be modeled by 10x+850.
George's score can be modeled by 50x+570.
We can set them equal to each other to see when they intersect.
10x+850=50x+570
40x=280
x=7
If George overtakes her in the 7th week, of course he'll have the higher score in 12 weeks.
Adjacent : 53. Is the answer
Answer:
640.56ft^2
Step-by-step explanation:
V=2πrh+2πr^2
V=2×3.14×6ft×11ft+2×3.14×6^2
V=6.28×66ft^2+6.28×36ft^2
V=414.48ft^2+226.08ft^2
V=640.56ft^2
