The current population of Fun City is 21000 people. If the population of the city will double every 51 years then the population

Arisa [49]

Answer:

The population of Fun City after 171 years would be 214563.

Step-by-step explanation:

The statement depicts a case of exponential growth, whose model is described below:

$p(t) = p_{o}\cdot r^{\frac{t}{T} }$ (1)

Where:

$p_{o}$ - Initial population, no unit.

$p(t)$ - Current population, no unit.

$r$ - Growth rate, no unit.

$t$ - Time, in years.

$T$ - Growth period, in years.

If we know that $p_{o} = 21000$ , $r = 2$ , $t = 171\,yr$ and $T = 51\,yr$ , then the population of the city after 171 years is:

$p(t) = 21000\cdot 2^{\frac{171}{51} }$

$p(t) = 214563$

The population of Fun City after 171 years would be 214563.

The difference of what integer and 5 is equal to 32?

irina1246 [14]

Answer:

Step-by-step explanation:

Let the integer be x.

Then the difference between the integer and 5 can be written as;

$x-5$

It was given that, the result is 32.

This implies that,

$x-5=32$

This is now a linear equation. We solve for x by grouping the similar terms to get,

$x=32+5$

This gives us

$x=37$

Therefore the integer is 37

Two skateboarders, Ron and Bob, are traveling in opposite directions.Ton travels at 8 feet per second and bob travels at 10 feet

omeli [17]

Time taken before they are 2640 feet is 146.67 seconds

Solution:

The distance is given by formula:

$distance = speed \times time$

Ton travels at 8 feet per second

Let us assume, time taken = t

speed = 8 feet per second

Then, distance is given as:

Distance covered by Ton = 8t

Bob travels at 10 feet per second

Then, distance is given as:

Distance covered by Bob = 10t

How long will it take before they are 2640 feet

Which means,

Distance covered by Ton + Distance covered by Bob = 2640

$8t + 10t = 2640\\\\18t = 2640\\\\Divide\ both\ sides\ of\ equation\ by\ 18\\\\t = 146.67$

Thus time taken before they are 2640 feet is 146.67 seconds

<h3>Method 2:</h3>

Since trains are moving in opposite directions, their speeds must be added

speed = 8 + 10 = 18 feet per second

Given distance = 2640 feet

Therefore, time taken is:

$time = \frac{distance}{speed}\\\\time = \frac{2640}{18} = 146.67 \text{ second }$

Thus time taken before they are 2640 feet is 146.67 seconds
