Answer:
3x - 13 +58 = 90, so 3x +45 = 90
Then 3x = 90 - 45 = 45 and x= 45/3 = 15.
m∠MNQ = 3x-13 = 3(15) - 13
= 45-13
= 32
Answer: B.
Step-by-step explanation: Remember, circumfrence is 2 pi r. multiply 6.1 and 2. That is 12.2. Then, use a calculator to multiply that to get approx 76.65. Round that up to 76.7.
Answer:
8:04 am
Step-by-step explanation:
The first train travels 60 miles from 6am to 7am
So at 7am the trains are 455 - 60 = 395 miles apart
First train: Distance from town A (DA) = Velocity* time = 60t
Second train: Distance from town B (DB) = Velocity*time = 70t
So, DA + DB = 60t + 70t
395 = 130t
t = 395/130
= 3.4 hrs
= 3 hrs 4 mins
The first train left at 5am so the exact time would be 8:04am (5am +3 hrs and 4 minutes)
