Answer : She will hike about 18 kilometers in 6 hours .
Explanation :
Since we have given that
on every 4 hours , she hikes about 12 kilometers
Hence, she will hike about 18 kilometers in 6 hours .
Answer: h = 7
Step-by-step explanation:
-h/-1 = -7/-1
so h = 7
Answer:
Diameter of pipe = D = 64mm
cross sectional Area of pipe= A = pi * (D/2)^2 = pi * (32)^2 = 1024pi mm^2
Discharge Rate of water = v = 2.05 mm/s
Volume of Cylinder = V = pi * (D/2)^2 * h = pi * (38)^2 * 2300 = 3321200pi mm^3
(Area of pipe)*(Rate) = (Volume) / (Time)
Time = T = (Volume) / [(Area of pipe)*(Rate)]
= (3321200pi)/(1024pi * 2.05)
= 1582.126524s
Answer:
The temperature of the solution after 3 hours rounded to the nearest whole degree is -6 C
Step-by-step explanation:
From the question, the temperature of the chemical solution at the start of the experiment is -14.96 C.
Now, if the temperature increases by 2.9 C each hour,
Then, after 3 hours, the temperature of the chemical solution would have increased by
2.9 C/h × 3 h
8.7 C
Hence, the temperature of the chemical solution would have increased by 8.7 C after 3 hours.
The temperature of the chemical solution after 3 hours will be
-14.96 C + 8.7 C
= -6.26 C
≅ -6 C (to the nearest whole degree)
