The goal of this project was to orbit a manned spacecraft around earth. question 1 options: a. gemini b. mercury c. international space station d. apollo

The answer would be Option A, Project Gemini. Even though project mercury was the first spacecraft with a person in it to go around Earth, it was manned remotely from Mission Control.

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
