Answer:
Option D.
3 equations with 3 variables
Step-by-step explanation:
The coordinates of a point in space must necessarily have 3 components. One to describe the distance on the x axis, another to describe the distance on the y axis to the point, and a third to describe the distance on the z axis.
If we have three variables, then 3 equations are needed to solve the system. With less than 3 equations it would be impossible to solver the system.
Therefore the correct answer is option D.
3 equations with 3 variables
Answer:
try 70
Step-by-step explanation:
Answer:
Step-by-step explanation:
The area of a prism is given by the product of the base and the height. In this triangular prism, the area of the either base is:
The height is marked as 
inches. Thus, the volume of the prism is:
Answer:
3
Step-by-step explanation:
see image
The volume of the cube is 6*6*6 (in cubed)=216 (in cubed).
in 1 cubic inch, there is 0.5 lb of weight
so in 216 cubic inch, there are 216*0.5 lb = 108 lbs of weight
Answer: 108 lbs
