Answer:
18 m^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2)h where b1 and b2 are the lengths of the bases and h is the height
A = 1/2 ( 5 + (6+1)) * 3
A = 1/2 ( 5+7)*3
= 1/2 (12)3
= 18
Answer:
Step-by-step explanation:
The solution is attached herewith.
The ratio of the rectangle's length to its width is 42/14 which simplifies to 3/1 by factoring out 14 out of the numerator and denominator.
Any ratio that is not 3:1, or a multiple of 3:1, is not equal.
List of Equal Ratios: 6:2, 9:3, 12:4, etc.
Answer:
a)
b)
Step-by-step explanation:
It can be seen in the graph that the water velocity and solution velocity is the same, but the salt concentation will be lower
Water velocity
Solution velocity
Brine concentration =
a) Amount of salt as a funtion of time Sa(t)
b)
This value was to be expected since as the time passes the concentration will be lower due to the entrance to the pure water tank
