This is a true statement.
Answer:
1/2 dozen of one score is 30%.
Step-by-step explanation:
As we know that 1 dozen = 12 units.
1/2 dozen = 1/2 times 12=6 units
1 score = 20 units.
By using this conversion, we get
6/2 times 100=30%
So 1/2 dozen of one score is 30%
Answer:
4 mph
Step-by-step explanation:
Travel time is proportional to distance and inversely proportional to speed. If c represents the speed of the current in miles per hour, an equation for the total trip time is ...
825/(29 -c) +825/(29 +c) = 58 . . . . . . hours travel time
825(29 +c) +825(29 -c) = 58(29 -c)(29 +c)
58c² -928 = 0 . . . . . . . rearrange to standard form
58(c -4)(c +4) = 0 . . . . factor
Values of c that satisfy this equation are 4 and -4. For the purpose here, we'll choose the positive solution.
The speed of the current is 4 miles per hour.
V = s/t ⇒ s = vt
25 mi/h · th + 45 mi/h · mh = 25mi · t + 45mi · m = (25t + 45m)mi
