Answer:
an irrational number unless the rational number is zero
Step-by-step explanation:
The only case when a product of a rational number times an irrational gives a rational number, is when the rational number is zero. Otherwise the product will always be irrational. The product of an irrational number that cannot be written as a quotient , times another one that can be expressed as a quotient will remain with the characteristic of not being able to be expressed as a quotient.
Answer:
one cubes: 73.5 ft²
two cubes: 147 ft²
Step-by-step explanation:
Using plastic to construct a cube means finding the surface area of the figure. The general formula for the surface area of a cube is:
SA = 6s², where 's' is the measure of one side.
Since one side is 3.5 feet:
SA = 6(3.5)² = 73.5 ft² per cube
Two cubes: 73.5 x 2 = 147 ft²
Answer:
there must be at least two lines on any plane because a plane is defined by 3 non-collinear points. Explanation: ... These lines may or may not intersect. If two of the 3 points are collinear, then we have a line through those 2 points as well as a line through the 3rd point.
