Answer:
If I am understanding your question, the total upstream is 8 miles and another 8 miles downstream.
Let s = the speed of the boat in still water
d = rt
8 = 5(s + 3) downstream
8 = 5s + 15 equation 1
8 = 5(s - 3) upstream
8 = 5s - 15 Add equation 1
8 = 5s + 15
16 = 10s Divide both sides by 10.
s = 16/10 = 8/5 = 1.6 mph
Answer:
y=(1/4)x + 9 OR y=x/4 +9
Step-by-step explanation:
Perpendicular lines have a slope/gradient of -1/n
Because the slope of this line is -4, the slope of a line perpendicular to it would be 1/4.
y=(1/4)x+b
(0,9) is the y-intercept, so b = 9
y=(1/4)x + 9 OR y=x/4 +9
3. C 67.5 mi
4. A 65mi
5. B $270
35 were not guppies.
Explanation:
63/9=7
7*4=28
63-28=35
