3.241208 × 10 to the eighth power
The answer is 2/11
hope this helps :)
B + 4b = 8
You have to combine the like terms and then divide both sides by the coefficient to isolate the variable b.
<em>b + 4b = 8
</em>5b = 8
(5b / 5) = 8 / 5
b = 1.6
Since it says to round to the nearest hundredth, I would just put a zero right after the tenths place.
b = 1.60

Answer:
- plane: 530 mi/h
- wind: 40 mi/h
Step-by-step explanation:
Let p and w represent the speeds of the plane and the wind. The relation between time, speed, and distance is ...
speed = distance/time
p +w = (2565 mi)/(4.5 h) = 570 mi/h
p -w = (2205 mi)/(4.5 h) = 490 mi/h
Adding these speeds, we get ...
(p +w) +(p -w) = (570) +(490) mi/h
2p = 1060 mi/h
p = 530 mi/h
Then the speed of the wind is ...
w = 570 mi/h -p = (570 -530) mi/h = 40 mi/h
The plane's speed is 530 mi/h; the wind speed is 40 mi/h.
