Answer:
The volume of fish tank is 
Step-by-step explanation:
Area of Base of fish tank = 
We are given that A fish tank has a base, B, with an area, in square inches, modeled by
So, 
Height of tank = x+3
Volume of tank = 
So, Volume of tank =
Volume of Tank =
Hence The volume of fish tank is 
Answer:
Step-by-step explanation:
x = larger number, y = smaller number
x + y = 57
x = 2y - 3
2y - 3 + y = 57
3y - 3 = 57
3y = 57 + 3
3y = 60
y = 60/3
y = 20 <=== the smaller number
x = 2y - 3
x = 2(20) - 3
x = 40 - 3
x = 37 <=== the larger number
Answer:
the second one that is 3y+1
Answer:
23
Step-by-step explanation:
225/25 = 21
21+2=23
Answer:
The problem in the first statement is that it does not say that the lines must be in the same plane.
Suppose in a 3D coordinate axis two lines as:
z = 0, y = 0 (this is the x-axis)
y = 1, x = 0 (this line is parallel to the z-axis but one unit above).
Those two lines are not parallel, and also never meet, so the definition is wrong.
The actual definition should be:
"Parallel lines are two lines that lie on the same plane and never meet"
B: The undefined terms are point, line, plane,...
An example can be "Plane", because if our lines do not lie on the same plane, then we can not use the concept of "parallel lines".
