Answer:
1) 45 minutes
2) they meet in 20 minutes
3) (12-6)/(20/60)=18kmh
Answer:
a) 40320 ways
b) 384 ways
Step-by-step explanation:
a) if there are no seating restrictions, the number of ways the 4 couples can be seated is the permutation of 8 persons in 8 seats then
number of ways= permutation of 8 persons in 8 seats = 8! = 40320
b) if each couple will sit together then the number of ways is:
number of ways= number of permutation of 4 integrants of each couple in 4 pairs of seats * number of permutation for a couple in a pair of seats^ number of pair of seats = 4! * 2^4 = 384
Answer: The cost of a small box is $4. The cost of a large box is $7.
Step-by-step explanation:
Let s = cost of a small box and L = cost of a large box
3s + 5L = 47
11s + 10L = 114
Multiply the top equation by -2 to combine with the second equation
-6s - 10L = -94
+11s +10L = 114
L cancels out, now solve for s
5s = 20
s = 4
Now, plug the value of s back into an equation to find the value of L
3(4) + 5L =47
12 + 5L = 47
5L = 35
L = 7
Two times the difference of x and seven plus ten
