In 2000, the population of Snowy Egrets went from 5,000 individuals to 15,000 individuals. What is the growth rate over those 4 years?

Answers

Answer:

[tex]x=\sqrt[4]{3}-1[/tex] or [tex]x=0.316[/tex]

Step-by-step explanation:

To write this equation you would need to use this equation for growth.

Final amount=initial amount (1+growth rate)^time

We have the final amount, 15,000, the initial amount, 5,000, and the time, 4 years. Now we have to plug in the values. We can write the growth rate as x.

[tex]15,000=5000(1+x)^4[/tex]

Now start by dividing both sides by 5000.

[tex]\frac{15000}{5000} =(1+x)^4[/tex]

[tex]3=(1+x)^4[/tex]

Now you can find the fourth root of both sides to get rid of the exponent.

[tex]\sqrt[4]{3} =1+x[/tex]

Finally, subtract 1 from both sides.

[tex]x=\sqrt[4]{3}-1[/tex]

And, if allowed, you can use a calculator to find the value in decimal form which would be:

[tex]x=0.316[/tex]

What are ratios and proportions?

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.

The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that John is collecting orange and green marbles in a bag. The ratio of orange marbles to green marbles is 6 to 4. If he has a total of 200 marbles in the bag.

The number of bags will be calculated as:-

6x + 4x = 200

10x = 200

x = 20

Orange = 6x = 6 x 20 = 120

Green = 4x = 4 x 20 = 80

solve for w and simplify this fraction 3/2w=-20​

Answers

Answer:

If I'm correct, the answer should be  negative 40/3.

Step-by-step explanation:

Because you first combine multiplied terms into a single fraction, then you multiply all terms by the same value to eliminate fraction denominators. Now you simplify it, by canceling multiplied terms that are in the denominator and then you multiply the numbers. Now you will divide both sides of the equation by the same term. Finally, you will simplify the equation.

x=11 and the measure for angle B is 80

Step-by-step explanation:

First you would set the equations equal to each other

8x-8 = 5x+25

-5x       -5x

Then i subtracted 5x from both sides

3x-8 = 25

  +8   +8

Then I added 8 to both sides

3x = 33

Divide both sides by three and you'll get x=11

A T-shirt takes ten minutes to make and a sweatshirt takes 20 minutes

items to sell. How many T-shirts and how many sweatshirts should you
make to maximize your profit? The profit per T-shirt is $6 and the profit
per sweatshirt is $20,

Answers

I would use T-Shirts as sweatshirts make you no profit. 20 hours = 1200 / 10 (cuz it takes 10 min) = 120.

So you can make 120 shirts. 120 x4(for the cost of supplies) =$ 480.

you would make profit of 120 x 6 = 720.

720 - 480 = 240.

You would make $240 profit of making 120 shirts

How to calculate unit price of something?

Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.

Thus, unit price of something is price of 1 thing.

Thus, suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.

It is given that Vera went to the local salon to get a haircut. The cost was $24. Vera tipped the hair stylist 18%.

SO,

18% = 18/100 = 0.18

18% of 24 = 0.18*24

= 4.32

The tip is $4.32

Adding this tip amount onto the original bill leads to;

4.32+24 = 28.32

Hence, the total cost of the haircut including the tip will be $28.32.

Read the passage.It might not be well known, but there is a desert in North America. It spans along the western side of the continent, from southern Oregon to northern Mexico. It is mostly contained in the arid area between the Rocky Mountains to the east and the fertile coast of the Pacific Ocean to the west. Researchers estimate that the desert is between 500,000 and 730,000 square miles.Differences of latitude, elevation, climate, topography, vegetation, soil, and human use have divided the desert into a cold region and a hot region. The cold region of the desert is known as the Great Basin Desert. This area covers almost all of Nevada, western Utah, and sections of the neighboring states. South of this basin is the Mojave Desert, which is the hot region of the North American Desert. This area covers much of California, southern Nevada, and some of Mexico.As a desert, the area is arid because of high evaporation, extreme temperatures, high winds, localized storms, and sun-beaten land. Life in the desert is a struggle for humans. People do live in this desert, but the pockets of people are dispersed and isolated. Native Americans and European settlers have added to the population of the region. Despite the harsh conditions, a surprising number of plants, animals, and reptiles make the desert their home. In fact, some species can only be found in the desert.What evidence does the author use to support the idea that there are people who live in the desert?
