What you bed to do is find the least common multiple of each number:

6, 12, 18, 24, 30, 36

9, 18, 27, 36

the least common multiple is 18 so every 18 days they will do laundry together

The population of a town grows at a rate proportional to the population present at time t. The initial population of 500 increas

tiny-mole [99]

Answer:

The population in 20 years will be 781.

Step-by-step explanation:

The population of the town can be modeled by the following equation:

$P(t) = P(0)e^{rt}$

In which P(t) is the population after t years, P(0) is the initial population and r is the growth rate, as a decimal.

The initial population of 500 increases by 25% in 10 years.

This means that $P(0) = 500, P(10) = 1.25*P(0) = 625$

We use this to find r.

$P(t) = P(0)e^{rt}$

$625 = 500e^{10r}$

$e^{10r} = 1.25$

Applying ln to both sides

$\ln{e^{10r}} = \ln{1.25}$

$10r = \ln{1.25}$

$r = \frac{\ln{1.25}}{10}$

$r = 0.0223$

$P(t) = 500e^{0.0223t}$

What will be the population in 20 years

This is P(20)

$P(20) = 500e^{0.0223*20} = 781$

The population in 20 years will be 781.

Just answer the question in simple words lol

Answer:

He should have multiplied 15 tsp by 1 tbsp/3tsp.

Step-by-step explanation:

The tsp labels cancel each other out when one is the numerator and one is the denominator.

15tsp x 1 tbsp/3tsp = 15/3 = 5 tbsp

How do you write 0.045 as a reduced fraction

Anvisha [2.4K]

0.045 = 45/1000

Divide top and bottom by their greatest common factor.
It looks to me as though the greatest common factor of 45 and 1,000 is 5 .
Divide top and bottom by 5 and we have <u>9/200</u> . That's the simplest form.
