The answer is (2) 9x2-19x+5.Because you need to first put them together linking by minus sign
160/3 is 53 1/3 as a fraction
Answer:
3
Step-by-step explanation:
50+10=60
20 x 3= 60
Try this solution:
D(f): √(2-x)≥0; ⇔ 2-x≥0; ⇔ x≤2 or x∈(-∞; 2].
So, we are given the speed in mi/min. We want to convert this to mi/hr. We can do this through cross multiplication.
(11 miles/1min) * (60min/hr) = 660 mi/hr
Now, we need to find the total distance flown:
TD= 6 trips*(500 miles/1 trip) = 3,000 mi
Lastly, we find total time using our converted speed and total distance.
speed = (total distance (in miles))/(total time (in hours))
660mi/hr= 3000mi / t
660t=3000
t=3000/660
t= 4.54 hrs
Answer: The plane will fly a total of about 4 and a half hours.
