If the distance from R to S is only half then the other half is S to T. The distance between R and S is (5,2). that should give you the answer
A.
Number of marbles with 'B' written on them is [ n(A)] = 6.
Total number of marbles [ n(S)] = 15.
Thus, Probability is
P(A) = n(A) / n(S)
= 6/15 = 2/5. ⬅️
B.
Number of green marbles [ n(A)] = 5.
Total number of marbles [ n(S)] = 15.
Thus, Probability is
P(A) = n(A) / n(S)
= 5/15 = 1/3 ⬅️
I am pretty sure it is c because it inot a rihght triangle and or it does not have an hypoteneus
1min: 100 ft
2min: 100(.5)= 50 ---> 100+50= 150 ft
3min: 50(.5)=25 ---> 150+25= 175 ft
4min: 25(.5)=12.5 ---> 175+12.5= 187.5 ft
5min: 12.5(.5)=6.25 ---> 187.5+6.25= 193.75ft
answer: 193.75 ft
