Answer:
1 mi/hr
Step-by-step explanation:
Given that:
Speed in still water, s = 5 mi/hr
Let speed of current = x
Time = distance /speed
Upstream (subtract speed of current) = 5 - x
Upstream time = 8 / 5 - x - - - (1)
Downstream (add speed of current) = 5 + x
Downstream time = 12 / 5 + x - - - (2)
Equate (1) and (2)
8 / (5 - x) = 12/ (5 + x)
8(5 + x) = 12(5-x)
40 + 8x = 60 - 12x
40 - 60 = - 12x - 8x
-20 = - 20x
x = 1
Spwed of current = 1 mi/hr
Answer: 376.8m
Step-by-step explanation:
Total surface area of a cylinder is calculated by 2πrh+2πr2, where π is a constant, given as 3.14, h is the height= 7m and r is radius= 5m
rh = 5m x 7m = 35m while
r^2 = 5m x 5m = 25m
Slot the values into the formula:
V = 2 x 3.14 ( 35) + 2 x 3.14 (25)
V= (6.28 x 35) + (6.28 x 25)
= 219.8 + 157
V= 376.8m
I hope this helps.

Answer:
B. y = -5x -2
Step-by-step explanation:
Fill in the given values in the form ...
y = (slope)x + (y-intercept)
y = -5x +(-2)
y = -5x -2 . . . . simplify; matches choice B
