Answer:
The motorist's average rate in the morning trip was 50 mph and that for the afternoon trip was 25 mph.
Step-by-step explanation:
Let the motorist's average rate in the afternoon = <em>x</em> mph.
It is given that his average rate in the morning was twice his average rate in the afternoon.
Therefore, his average rate in the morning = 2<em>x</em> mph.
Let <em>t</em> be the time taken for the morning trip.
It is given that he spent 5 hours for driving.
So, the time taken by him for the afternoon trip = 5 - <em>t</em>.
Now, using the formumla,
,
the verbal model for the morning trip is:
![2x=\frac{150}{t}](https://tex.z-dn.net/?f=2x%3D%5Cfrac%7B150%7D%7Bt%7D)
<em>xt</em> = 75
The verbal model for the afternoon trip is:
![x=\frac{50}{5-t}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B50%7D%7B5-t%7D)
5<em>x</em> - <em>xt</em> = 50
Substituting <em>xt</em> = 75, we get,
5<em>x</em> - 75 = 50
5<em>x</em> = 125
<em>x</em> = 25
2<em>x</em> = 50
Hence, his average rate in the morning trip was 50 mph and that for the afternoon trip was 25 mph.
Answer:
26%
Step-by-step explanation:
345. 24 - 274 = 71.24
71.24 / 274 =0.26
0.26 * 100 = 26
Answer:
The y intercept is -1 and the slope is 4/1
Step-by-step explanation:
When you are trying to find the y-intercept, you look at where the line crosses over the y axis. In this case it was at -1.
The slope indicates how many units it is going up/down or left/right. In this case, the distance between each point is up 4, and right 1. so the slope would be 4/1.
I hope this helps :)
Answer:
Answer is: two electrons.
n - principal quantum number, indicating relative overall energy of each orbital, n=1,2,3,...
l - angular momentum quantum number, shape of the orbital, l = 0,1,...,n−1.
l =1 for the p orbitals.
ml - magnetic quantum number, ml = 0,±1,...,±l.
This is 2px orbital, in every orbital there is two electrons with different spin.
