Need This For Homework 1.What Happens When Fertilizer Ends Up In Waterways?2. Describe Eutrophication.3.

Answers

Answer 1

Answer:

1.When manure or commercial fertilizers enter surface water, the nutrients they release stimulate microorganism growth. Without sufficient dissolved oxygen in surface water, fish and other aquatic species suffocate. The resulting dead fish and other aquatic species degrade the water quality and cause unpleasant odors.

2.Eutrophication is a significant increase of algae (microscopic organisms similar to plants) due to the greater availability of one or more growth factors necessary for photosynthesis, such as sunlight, carbon dioxide and nutrients (nitrogen and phosphorus)

3. I don't know I am way to tired sorry

Step-by-step explanation:

Answer 2

1. When manure or fertilizers enter water, the nutrients they release stimulate microorganism growth. These microorganisms reduce the dissolved oxygen content of the water body. Without sufficient dissolved oxygen in water, fish and other animals living in water suffocate.

2. Eutrophication is the process by which water bodies are enriched with minerals and nutrients.

In a survey of 160 people who have reptiles as pets, 40% have a pet snake. Of those with a pet snake, 25% also have a pet lizard. Of those who do not have a pet snake, 75% have a pet lizard.
Part A
Enter the correct answers in the boxes to construct a two-way frequency table to display the data.
Part B
What percentage of those surveyed have a pet lizard?
Part C
What percentage of those surveyed have both a snake and a lizard?

Answers

Part a is the answer

Percentage of people having Lizard = 55% , Percentage of people having both Lizard & Snake = 10%

Important Information : Percentage people having pet snake = 40%

C] Percentage people having pet lizard, along with pet snake = 25% of those having pet snake = 25% of 40% = 10% {Percentage of people having both snake & lizard)

Percentage of people having pet snake only = 75% of those who don't have snake = 75% of ( total - 40%) = 75% of 60% = 45%

B] Total percentage of people having pet lizard = 10% + 45% = 55%

Step-by-step explanation:

The value of a share of stock decreases in value at a rate of $1.40 per hour during the first 3.5 hours of trading. Enter and solve an equation to find the decrease in the value of the share of stock during that time. Let x represent the decrease in value of the share of stock during 3.5 hours.


The equation to find the decrease in the value of the share of stock is x / _____ = _______


The decrease in value of the share of stock during 3.5 hours was $________​

Answers

Answer:

x/3.5h = -$1.4

So, x = -$1.4 * 3.5h

= -$4.9

Step-by-step explanation:

Since your losing $1.4 every hour, the 1.4 is supposed to negative.

Also, since your losing that amount of money for 3.5 hours, we are trying to find the total of how much money is lost in the 3.5 hours. To do this, we have to do x/3.5h = -$1.4. But since you can't do x/3.5, we have to do inverse operation. When you divide 3.5 hours to the other side of the equation it becomes multiplication. So you do -$1.4 times 3.5 hours

and get  -$4.9.

2. Apples cost more per pound.

Step-by-step explanation:

1. Brian reads 2/15 in 20 minutes, like we were told. It's easy to determine how much of his book he can read within an hour, by using the ratio 1/15:10. There's clearly 1/15 in 10 minutes, 2/15 in 20, 3/15 in 30, and so on. This would result in him reading 6/15's of his book in an hour.

2.

Peaches

0.6÷8/5 converts to .6 × 5/8. The result is .375.

Apples

1.75 ÷7/2 converts to 1.75×2/7. The result of this equation is .5, so therefore, the apples cost more per pound.

8/15 because 2/15 *3 is 6/15 + 2 is 8 and you multiply by 3 because 60/20=3

Hey there!

In order to solve for this particular question that you have asked.. we can just simply divide 28 from 4

Equation: 28 / 4

28 ÷ 4 / 4 ÷ 4

28 ÷ 4 = 7

4 ÷ 4 = 1
