Answer:
165 ways to choose the paintings
Step-by-step explanation:
This is clearly a Combination problem since we are selecting a few items from a group of items and the order in which we chosen the items does not matter.
The number of possible ways to choose the paintings is;
11C3 = C(11,3) = 165
C denotes the combination function. The above can be read as 11 choose 3 . The above can simply be evaluated using any modern calculator.
Answer:
226.7 cm³
Step-by-step explanation:
The cone volume formula is V = (1/3)(base area)(height).
Here that comes out to V = (1/3)(pi)(3.8 cm)^2·15 cm, or 226.7 cm³
Answer:
I am pretty sure that your answer would be 3.
Step-by-step explanation:
The reason why is because if B if half of line segment AD and AD is equal to 12, then B must be equal to 6 since half of 12 is 6. Next, since C is the mid-point for line segment BD then C must be 3 since half of 6 is 3. And finally, that means line segment BC is three since it is 1/2 of BD.
Hope this helps! :)
