The distance between A and B is 1020 mi. 1020-170=850 miles traveled. Let n and n+10 be the speeds of the two trains. Since they are traveling towards each other, their speeds are combined. So:
5(n+n+10)=850 is the answer Hope you get a good grade
12 + 11 + 6 = 29 people like the drinks. So subtract 29 from 50 and you get 21 people who don't like either.
Answer:
since a diameter is twice if a radius
5.4 x 2
diameter= 10.8
circumference= 2x pi x r= 2 x 3.14 x 5.4
33.912cm
40cm( approximately)
P = 2 x (5,5 + 3,5) = 18 cm
P = is the circumference of the figure
