Answer: the return trip took approximately 4 hours.
Step-by-step explanation:
Erica and her friends rode a train to get to their vacation destination. The time that it took them to get to their vacation destination is 5 hours.
The return trip was only 5/6 of the time of the original trip. Therefore, the time that they spent on the return trip would be
5/6 × 5 = 25/6 = 4.16667
Rounding up to the nearest whole number, it becomes 4 hours
3 quarters of 2pi.r should not exceed 38. So r<38/(3/2pi) => r<8.06. That leaves answer A and B.
Step-by-step explanation:
as the sum of the interior angles of a triangle is 180..so
a+b+c=180
(x+2)+x+(6x+10)=180
now
add all variables and all numbers
so
8x+12=180
8x=180-12
8x=168
x=168/8
x=21
now put the values
a=x+2
21+2=23
b=x
21
c=6x+10
136
verify
23+21+136=180
