Answer:
It will take 58 seconds
Step-by-step explanation:
If you have 1 kg of water in the jar, half of it will be 0.5 kg.
To vaporize half of the water (0.500 kg) the energy supply needed is

If the stove is supplying 20 kJ/s, the time its needed is

It will last at least 58 seconds to vaporize half of the water.
Answer:
2 1/3
Step-by-step explanation:
<span>A = Area
L= Length = 15
W + widith = 10
A = 150
The pool area is
L = 10
w= 5
A= 50
So the area of the perimeter = 100 square meters</span>
Another way to solve this is to use the Midpoint Formula. The midpoint of a segment joining points

and

is

So the midpoint of your segment is

Perhaps it helps to see that the x-coordinate of the midpoint is just the average of the x-coordinates of the points. Ditto for the y-coordinate of the midpoint; just average the y's.
