Hi!
So, 32/4=8. Each side is 8 feet long, with a square area of 64 ft^2. If you devide 32/3, that's 10.6 feet you painted. That aside, it's not what the question asks.
If you painted 1/3, and there are four sides, 12 can be used as it is the lcm (least common multiple). 4/12 can be used here, I believe.
If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer, if other people did not provide a helpful answer (but, I'm sure they did!). I want to be able to assist more users one-on-one! :)
The square root of 5 is 2.23 so it would be closer to 2
330 km/hr
Step-by-step explanation:
To find speed of the plane against the headwind;
600 km / 2 hours = 300 km/hr
Speed of plane with the wind in its back;
600 km / 5/3 hours = 600 * 3/5 = 360 km/hr
We can create a simultaneous equation from this data.
Assume the speed on pane in still air is x km/h
Assume the speed of wind is y km/h
Therefore;
x – y = 300
x + y = 360
Solving the simultaneous equation by elimination gives us;
x – y = 300
-
x + y = 360
=
-2y = - 60
y = 30
x = 330
The speed of the plane without wind is;
= 330 km/hr
The wind speed is;
= 30 km/hr

I’m not sure what a natural number means, but some simple ones are
2 x 47
10 x 9.4
12 x 7
Since class starts at 8:30, you would subtract 15 from 8:30 (Because he wants to be 15 minutes early)
It takes him 25 minutes to bike to school, and 8:15 -:25 is 7:50.
You can come to this conclusion by adding the two times, and subtracting them from 8:30 as well!
