10 mins = 1 miles
1 hour = 1 x 6 = 6 miles
8 hours = 6 x 8 = 48miles
The jogger could cover 48 miles a day.
3987 ÷ 48 = 83.06 days
It takes 83.06 days to jog the length of this frontier.
83.06 days ÷ 7 = 11.87 weeks = 12 weeks (round to the nearest whole number)
It takes 12 weeks to jog the length of this frontier.
Answer:
Step-by-step explanation:
Let f represent the number of first-class tickets that Sarah bought. Then she bought (16-f) coach tickets. Her total spending for airfare was ...
1140f +160(16-f) = 9420
980f +2560 = 9420 . . . . simplify
980f = 6860 . . . . . . . . subtract 2560
f = 7 . . . . . . . . . . . . . divide by 980; number of first-class tickets
(16-f) = 9 . . . . . coach tickets
Sarah bought 7 first-class tickets and 9 coach tickets.
That would be of order 2 answer
Option A
I hope this helps you
at the 30-60-90 triangle has rules
30=>k
60=>k(square root of) 3
90=>2k
so in this triangle 60=> see 9
k(square root of) 3=9
k=9/(square root of) 3
2k=18/(square root of) 3
at the 45-45-90 triangle rules are
45=>2k
45=>2k
90=>[2k/(square root of 3)] (square root of) 2
x=[18/(square root of 3)].(square root of 2)
x=18(square root of 2)/square root of 3
360÷60=60 60 miles per hour 6840÷45=152 152 costumes per day 45.5÷13=3.5 rounded to nearest hundred= 4 4 meters per second $7.40<span>÷5=$1.48 rounded to nearest hundred = 1 $1 per pound</span>
