if a man walks at the rate of 2 feet per second, how many minutes will it take him to walk 4320 feet?

Ok so if a man walks 2 ft per second you would want to find out how many seconds it takes to walk 1 foot so it takes .5 seconds to walk one foot so then you multiply 4320X.5 which then equals 2169 seconds then divide that by 60 which equals 36min.

Answer: 36 minutes

Step-by-step explanation:

The formula to find the speed is given by :-

$\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}$

Given : A man walks at the rate of 2 feet per second .

Distance covered by him = 4320 feet

Let t be the time taken by him to walk 4320 feet, then we have

$2=\dfrac{4320}{t}\\\\\Rightarrow\ t=\dfrac{4320}{2}=2160\text{ seconds}$

Since 1 minute = 60 seconds

Then , $t=\dfrac{2160}{60}=36\text{ minutes}$

Hence, it will take him 36 minutes to walk 4320 feet .

A tank contains 100 kg of salt and 1000 L of water. A solution of a concentration 0.05 kg of salt per liter enters a tank at the

Umnica [9.8K]

Answer:

Step-by-step explanation:

Initial Quantity of salt Q(0) = 100 kg

Capacity of tank = 1000 L

Inflow of liquid = 10 l /minute and outflow = same rate thus leaving the content of volume 1000 L at any time

Assume after entering constantly mixes and drains out.

Concentration flow = inflow - outflow

= 0.05(10) - $\frac{Q(t)}{1000} *10$

i.e. $Q'(t) = 0.5-0.01Q(t)$ , Q(0) = 100

$Q'(t) = -0.01(Q(t)-50), Q(0) = 100\\\frac{dQ}{Q-50} =-0.01 dt\\ln |Q-5| = -0.01t +C\\Q-50 = Ae^{-0.01t}$

Use Q(0) = 5

-45 = A

So the equation would be

$Q-50 = -45 e^{-0.01t} \\Q(t) = 50-45 e^{-0.01t} \\$

a) Initial concentratin = $\frac{100}{1000} =0.10$

b) Use the solution fo rDE substitute t =1

Q(1) = 50-45e^(-0.01) = 5.4477 kg

c) As t becomes large Q = 50

So concentration limit = 50/1000 = 0.05

I REALLY NEED HELP!

Snowcat [4.5K]

Answer:

Step-by-step explanation:

The compound interest formula is $A = P (1+r/n)^nt$ where:

P is the starting amount called the principle
r is the rat written as a decimal
n is the number of times compounded in a year
t is the number of years

Substitute a value into each variable to solve.

P = $147 since 10% of 1,470 is being invested which makes P = 0.10(1470) = 147.

The rate is 3.5% or r = 0.035.
n = 12 because it is compounded monthly meaning 12 times a year.
t = 25 since it will earn for 25 years.

$A = P (1+r/n)^{nt}\\A = 147(1 + \frac{0.035}{12})^{12*25}\\A = 147 ( 1 + 0.002916)^{300}\\A = 147(1.002916)^{300}\\A = 352.19$

Repeat this process for each formula.
