Answer: The required probability is 
Step-by-step explanation:
Since we have given that
Number of spruce tree = 20
Number of maple tree = 50
Total trees = 70
We need to find the experimental probability that the next tree Colleen to get a spruce tree.
So, the probability would be :

Hence, the required probability is 
Answer:
4ft
Step-by-step explanation:
500=pir^2h
r^2=500/(10*pi)
r=3.989ft
Answer:
definition the set of positive real number which greater than 0 are the nonnegative number. for ex=(1,2,3...10)
Answer: A. UWV and UWZ are complementary angles.
B.They do not overlap, so UWV and VWX are supplementary angles
Step-by-step explanation:
Complementary angles add up to 90.
Supplementary angles do not overlap.
Answer:
no
Step-by-step explanation:
8, 10, 6
10 - 8 = 2
2 + 6 = 8
