Question 1 answer: 5/3 miles per hour
reason: 1/3 divided by 1/5
Answer:
s(2) = √7
Step-by-step explanation:
s(2) = √(3[2] + 1) = √7
Answer:
about 3 1/2 hours long
Step-by-step explanation:
70 goes into 240 evenly 3 times, and 70×3 equals 210. that leaves 30 miles remaining. since he is moving at an average rate of 70mph, 3/7 would be the remaining time. to decimal that equals a total of about 3 hours and 25 minutes, which, rounded up, equals 3 and 1 half hours.
By definition,
sin(angle) = opposite/hypotenuse
From the picture,
sin(60°) = VT/PV
√3/2 = VT/35
√3/2*35 = VT
30.3 meters = VT
