Answer:
Step-by-step explanation:
Supplementary angles are angles equal to 180°.
Therefore:
Now that we have our equation, let's distribute the 
and the 
into the parentheses they are next to:
Combine like terms:
Subtract 
from both sides of the equation:
Divide by the coefficient of 
, which is 
:
~
Check your work by substituting 
into one of the equations above:
It's correct!
1331= lwh or 1331= x^3
So take cube root of both sides and you will get 11.
Since the formula for area is length times width, the answer is 11x11 which equals 121.
So the square area of the base is 121mm^2
6,000 feet is the answer to plane A.
Answer:
67.17
Step-by-step explanation:
First, identify the hundreds digit (the 7)
Next, identify the next smallest place value (the 1)
Then, determine if 7 greater than or equal to 1. Yes, it is greater than 1, so round up. Increase the hundreds digit by one, so 7 becomes 8.
Finally, keep .17 and you get an answer of 67.17.
Answer:
156
Step-by-step explanation:
to find length you do area/width. So 1248/8=156
