good luck hope this helps.
Given that
time required to filled 1/7 of pool = 1/10
so time required to fill 1 pool = 1/10 ÷ 1/7 = 1/10 × 7 = 7/10 hrs
So 0.7 hrs will require to fill the pool at given rate
17x= 13 and 8 are both y's so you combine them by subtracting 13 from both sides and then you have 17x=-5y
Answer:
20 possible arrangements
Step-by-step explanation:
A: Alice
B: Bob
C: Cindy
X: other student
All the possible arrangements are:
When Bob is in the first place
B A C X X
B A X C X
B A X X C
B X A C X
B X A X C
B X X A C
6 possible arrangements
When Bob is in the second place (notice that neither Alice nor Cindy can be before Bob)
X B A C X
X B A X C
X B X A C
3 possible arrangements
When Bob is in the third place
X X B A C
Only 1 possible arrangement.
Total arrangements when Bob is before Cindy: 10
If Cindy is before Bob the same situations are repeated, given another 10 arrangements. So, the total line up in which Alice is somewhere between Bob and Cindy are 20.
