Answer:
6 hours
Step-by-step explanation:
Firstly, it is important to know where the train that leaves Washington will get after one hour since they didn't start at the same time between noon and 1 is 1 hour.
Speed = distance / time
Distance = speed * time
The distance S = 44 * 1
S= 44m
To determine the time they will pass each other
500(total distance)- 44 ( distance gotten to in 1 hour) - d(the distance it willl pass each other =44* t(time the train will pass each other.
456-d =44t
Second train
d = 32t
Substituting to the equation
456-32t=44t
456=76t
t= 6 hours.
The time they will pass each other is six hours.

Answer:
Quality Plumbing charges more per hour.
In the graph, you can see that it would cost $150 for their work plus $100 per hour based on the slope of the line.
A Plus Plumbing charges $140 for their work plus $60 per hour.
Two<span> trains </span>leave different<span> cities heading toward each </span>other<span> at </span>different<span> speeds. ...

Answer:
the ratio of the surface area of Pyramid A to Pyramid B is: 
Step-by-step explanation:
Given the information:
- Pyramid A : 648
- Pyramid B : 1,029
- Pyramid A and Pyramid B are similar
As we know that:
If two solids are similar, then the ratio of their volumes is equal to the cube
of the ratio of their corresponding linear measures.
<=> 
=
= 
= 
<=> 
Howver, If two solids are similar, then the
n ratio of their surface areas is equal to the square of the ratio of their corresponding linear measures
<=> 
=
So the ratio of the surface area of Pyramid A to Pyramid B is:
