Haha, I don't think those answers belong to the question asked :P
The probability of rolling less than 3 is 2/6=1/3
So if you rolled 450 times you should expect to roll less than 3:
450(1/3)=150 times.
Answer:
12.5 pi or 39.26990
Step-by-step explanation:
First we can find the radius, which is half the diameter, 5 feet. To find the area of a semi-circle we would find the area of the circle and then divide by 2:

We can substitute what we have:

This gives us:
12.5 pi or 39.26990(Not sure what format you need it in)
Answer:
3 km
Step-by-step explanation:
Lets say that you flipped the smaller triangle to be facing the same way as the bigger triangle. To find the X side, we need to do 4.5/1.2 = 1.75. which is the difference between the sides. So then we do 1.75 x 0.8 = 3.
Sorry if I couldn't explain well enough, which is not something I'm good at. I hope you get the question right! Glad I could help! :)
