The LCM of 4,10 and 12 is 60.
Answer:
187
Step-by-step explanation:
We make an equation to find the average of all three games: (139+184+x)/3=170 . x is the value of the third game to get an outcome of at least 170, and when you solve the equation you get 187.
The formula for volume of a pyramid is V = 1/3 bh. If we plug everything into the formula, you should get an answer of 17cm cubed. Hope this helps!
