Romashka-Z-Leto [24]

Answer:

a) The equation can Nina use to find how many times as many papers she delivered the second week as the first week is given as:

8x = 32

b) Nina delivered 4 times as many papers the second week as the first week

Step-by-step explanation:

From the question, we are told that:

Nina delivers newspapers.

In the first week, she delivers 8 papers.

In the second week, she delivers 32 papers.

Let x represent the number of times

The equation can Nina use to find how many times as many papers she delivered the second week as the first week is given as:

8paper × x = 32 papers

8x = 32

Solving for x

8x = 32

x = 32/8

x = 4 times

Therefore, Nina delivered 4 times as many papers the second week as the first week

Alja [10]

Answer:

t = 460.52 min

Step-by-step explanation:

Here is the complete question

Consider a tank used in certain hydrodynamic experiments. After one experiment the tank contains 200 liters of a dye solution with a concentration of 1 g/liter. To prepare for the next experiment, the tank is to be rinsed with fresh water flowing in at a rate of 2 liters/min, the well-stirred solution flowing out at the same rate.Find the time that will elapse before the concentration of dye in the tank reaches 1% of its original value.

Solution

Let Q(t) represent the amount of dye at any time t. Q' represent the net rate of change of amount of dye in the tank. Q' = inflow - outflow.

inflow = 0 (since the incoming water contains no dye)

outflow = concentration × rate of water inflow

Concentration = Quantity/volume = Q/200

outflow = concentration × rate of water inflow = Q/200 g/liter × 2 liters/min = Q/100 g/min.

So, Q' = inflow - outflow = 0 - Q/100

Q' = -Q/100 This is our differential equation. We solve it as follows

Q'/Q = -1/100

∫Q'/Q = ∫-1/100

㏑Q  = -t/100 + c

Q(t) = e^{(-t/100 + c)} = e^{(-t/100)}e^{c}  = Ae^{(-t/100)}\\Q(t) = Ae^{(-t/100)}

when t = 0, Q = 200 L × 1 g/L = 200 g

Q(0) = 200 = Ae^{(-0/100)} = Ae^{(0)} = A\\A = 200.\\So, Q(t) = 200e^{(-t/100)}

We are to find t when Q = 1% of its original value. 1% of 200 g = 0.01 × 200 = 2

2 = 200e^{(-t/100)}\\\frac{2}{200} =  e^{(-t/100)}

㏑0.01 = -t/100

t = -100㏑0.01

t = 460.52 min

Nick can read 3 pages in 1 minute. write the ordered pairs for nick reading 0,1,2 and 3 min
Elis [28]
For 0 minutes, it would be 0 minutes (obviously)
for 1 minute, it would be 3
for 2 minutes, it would be 6 pages
and finally, 3 minutes, will be 9.
to get the answers, you would just have to add 3, since every minute, nick reads 3 pages.
