Answer:
The time taken is 4.79 minutes.
Step-by-step explanation:
[tex]P = Po(1.4)^{t}[/tex]
initial Population, Po = 400
Final population, P = 2000
Let the time is t.
[tex]2000 = 400(1.4)^{t} \\5 = (1.4)^t\\log 5 = t log 1.4\\0.6989 = 0.146 t \\t = 4.79 minutes[/tex]

The best models a. are mathematical models. b. replicate all aspects of the real-world object or decision. c. replicate the characteristics of a component in isolation from the rest of the system.
Answer:
accurately reflect relevant characteristics of the real-world object or decision
Step-by-step explanation:
a. are mathematical models. b. replicate all aspects of the real-world object or decision. c. replicate the characteristics of a component in isolation from the rest of the system.
accurately reflect relevant characteristics of the real-world object or decision
A model is an abstraction of reality. not all good models are mathematical. there are good models in economics that are accurate and do not use maths. e.g. law of demand
It is impossible for a model to replicate all aspects of the real-world object or decision. It will only be able to reflect relevant characteristics of the real-world object or decision. All other factors would be held constant

Teachers were told that next year they would receive a percent increase in their salary. Mrs. Bennett is making $32,000 a year and will receive $2,550.00 more next year. What is the percent increase? Round to the nearest percent. I need this answer ASAP please and thank you!
Answer:
7.97%
Step-by-step explanation:
Given data
Original Salary= $32,000
Increase= $2,550.00
percent increase= increase/original *100
Percent increase= 2,550.00/32000*100
Percent increase= 0.0796875*100
Percent increase= 7.97%
Hence the increase is 7.97%
Jason wants to earn at least $250 each week working during the summer.
Jason earns $6.00 an hour babysitting.
Jason earns $7.75 an hour working at a store.
He can work no more than 40 hours each week.
Let b equal hours of babysitting, and s equal hours working at the store.
Which system of inequalities models the constraints?
6.00b + 7.75s ≤ 40
b + s ≥ 250
6.00b + 7.75s ≥ 250
b + s ≤ 40
6.00b + 7.75s ≥ 40
b + s ≥ 250
6.00b + 7.75s ≤ 250
b + s ≤ 40
Answer:
6.00b + 7.75s ≥ 250
b + s ≤ 40
Step-by-step explanation:
6.00b + 7.75s ≥ 250---this represents how much he will make
b + s ≤ 40---these are his hours. B+S are his hours, and they can't be greater than 40 hrs, so ≤.
At Bike Shop X it costs $2.75 per hour plus a $3.00 deposit to rent a bike. At Bike Shop Z it costs $ 1.75 per hour plus a $7.00 deposit to rent a bike.

Brayden is buying a new video game console for $356.88, which includes tax. If
he made a down payment of $50, what would his monthly payment be if he
paid the rest in 8 months (each of equal payments)?
Answer:
His monthly payment would be $38.36
Step-by-step explanation:
Firstly, we subtract the down payment from the total
We have this as;
356.88 - 50 = 306.88
Now, to get the monthly payment, we have to divide this by 8
We have this as;
306.88/8
= $38.36
