Divide 81/289 and see the decimals value
then check each answer choice and the one with the same decimals value as your question is your answer
Answer:
the value of X is 122
Step-by-step explanation:
First, all triangle angles add up to 180 so to find the missing angle we subtract 51 and 71 from 180 and get 58
Now we know straight lines always equal 180 as well so we subtract 58 from 180 and get 122 and that is the value of x
The volume is
.. V = π*r^2*h
.. = π*(4.5 ft)^2*(25 ft)
.. ≈ 1590.43 ft^3
The closest choice is C 1589.63 ft^3.
_____
Apparently, someone used the 3-digit approximation 3.14 for π to compute a 6-digit result. That is why it is wrong in the last 3 digits.
A rational number is any number that can be turned into a fraction....it can be negative or positive.
Therefore, -12/6 is a rational number
Answer:
