Answer:
Step-by-step explanation:
As the numbers are only between 1 and 30
Total number of possible combinations = 30×30×30 = 27000
If there are 100 attempts then
∴ Probability someone can guess the correct combination given 100 attempts is 
Answer:

It is D , if you plus into a calculator it simplifies for you !!
1) the sum of all three angles in a triangle is always 180, so number 5 is w=80
2)I assume they mean x. since the x angle and the 70 angle are a linear pair they must add to 180, so x has to be 110
3) the top 60 angle makes a vertical angles with the angle right below it. since vertical angles are congruent, the angle below has to be 60 also. again all 3 must add to 180 so o is also 60
4) these are all linear pairs. every angle shown has to be 90
4(pi)m^2 = 144(pi)
4m^2 = 144
m^2 = 36
m = 6cm
diameter = 2m
= 2(6)
= 12cm
