Answer: Where?
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
48 times 2/3 gives you the amount of runners that dropped out in the first half of the race. take that number (32), and subtract it from the original. You should be left with 16. Then take 1/4 of the remaining runners (16 times 1/4, which is 4), and subtract it from 16. this gives you 12
Answer:
-5/3 x (-1/8 )= 5/24 = 0.2083333
Step-by-step explanation:
.5. To get this, multiply 5 x .1
Answer: V = 5.22m/s
Step-by-step explanation:
Given that the mass of the particles is proportional to the fifth power of the speed. That is
M = k V^5
Where M = mass and V = speed
K = constant of proportionality
A certain river normally flows at a speed of 3 miles per hour
V = 3 mph
M = unknown
M = k × 3^5
M = 243K
K = M/243 ........(1)
What must its speed be in order to transport particles that are 16 times as massive as usual
M = 16M
Using same formula
I.e M = KV^5
16M = M/243 × V^5
M will cancel out
16 = V^5/243
V^5 = 3888
V = 5.22m/s
