<h3>
Answer: Choice A</h3>
Explanation:
When we rotate a rectangle around an axis of symmetry, we end up with a cylinder. Think of a revolving door or a turbine. The flat door moves through 3D space to produce or carve out a 3D cylinder.
This figure is composed of two rectangles, so we'll end up with two cylinders. They will both share the same center, so we'll have a sideways two-layer wedding cake structure when everything is said and done. This points to choice A as the final answer.
Answer:
x = 1
Step-by-step explanation:
4(2x + 1) - 3 = - 3(x - 4) ← distribute parenthesis on both sides
8x + 4 - 3 = - 3x + 12
8x + 1 = - 3x + 12 ( add 3x to both sides )
11x + 1 = 12 ( subtract 1 from both sides )
11x = 11 ( divide both sides by 11 )
x = 1
Theres an infinite amount of numbers because you could have 0.10123 to 0.19998298 its never ending
Answer:
A
Step-by-step explanation:
Metal is stronger than plastic, but it is also much heavier.
The key idea in this paragraph is to highlight how to transport the required materials while reducing the weight as much as possible so orbital velocity can be achieved while breaking through the resistance of the atmosphere.
This statement is the key one because it gives engineers the problem they need to find the answer to make the space exploration a reality.
