The Hamptons Family has a fish tank holding 10,450 ml of water. The water is leaking at a rate of 270 ml per minute.

Part A: Define the input and output in the given scenario.

Part B: Write a function to model this situation.

Part C: How many liters of water will be left in the tank after 10 minutes
(hint: liters, not milliliters)

Answers

Answer:

The output would depend on the input so relating this to the question, the input is the time (in minute) and the output is the amount of water left in the tank

We can give a letter 't' for the time, the input, and f(t) for the output

----------------------------------------------------------------------------------------------------------------

The original amount of water in the tank is 10450, so this will be the fixed constant.

The amount of water lost per minute is 270 so this will be the term that varies depends on the variable of time, we write this as 270t

The function is given f(t) = 10450 - 270t

--------------------------------------------------------------------------------------------------------------

Given, t = 10

f(10) = 10450 - 270(10)

f(10) = 7750 ml

Step-by-step explanation:

Answer:

Part A:

Since the rate of 270 ml per minute has units of ml per minute, then yy must have units of ml and x must have units of minutes. The input must then be the number of minutes the tank is leaking for and the output is the number of ml of water remaining in the tank.

Part B:

Since the tank is leaking 270 ml per minute, then after x minutes, 270x ml of water has leaked out of the tank. The tank initially has 10,450 ml of water so after x minutes, there is y=10,450−270x ml remaining in the tank.

Part C:

After x=10 minutes, the amount of water remaining in the tank is y=10,450−270(10)=10,450−2,700=7,750 ml. There are 1,000 ml in 1 liter so 7,750 ml = 7.75 liters. There are then 7.75 liters of water left in the tank after 10 minutes.

Step-by-step explanation:

Since, simple interest is,

Where, P is the principal amount,

r is the annual rate of interest,

t is time ( in years ),

Part A : Here, S.I. = $ 444,

t = 3 years,

r = 4 %,

Thus,

Hence, She borrowed $ 3700.

Part B :

Here, r = 5 %, t = 3 years, P = $ 3,700,

Hence, She would pay $ 555 interest.

The amount of water an electric dishwasher uses to wash dishes varies directly with the number of loads of dishes. The dishwasher uses 32 gallons of water to wash 4 loads of dishes.

How many gallons of water will the dishwasher use to wash 12 loads of dishes?

Answers

Answer:

I believe it 96.

Step-by-step explanation:

32÷4=8

4×8=32

12×8=96

Answer:

96 gallons

Step-by-step explanation:

So to wash 4 loads of dishes, you need 32 gallons. If you divide 32 by 4 you get 8. That means you need 8 gallons of water per load. Since there are 12 loads and you need 8 gallons per load, if you multiply 8 X 12 you get 96. This means you need 96 gallons of water for 12 loads of dishes. Hope it helps!

Answers

Answer:

16 (1+2)

Step-by-step explanation:

factors of 16: 1,2,4,8,16

facfors of 32: 1,2,4,8,16,32

16 x 1 = 16

16 x 2 = 32

We are required to write 16 + 32 as a product of two factors using the GCF and the distributive property.

16 + 32 as a product of two factors using the GCF and the distributive property is 16(1 + 2)

given:

16 + 32

Factors of 16 = 1, 2, 4, 8 and 16

Factors of 32 = 1, 2, 4 8, 16 and 32

The highest common factor of 16 and 32 is 16

check a factor of 16 that can multiply 16 to give 16

= 16 × 1

check a factor of 32 that can multiply 16 to give 32

= 16 × 2

So,

(16 × 1) + (16 × 2)

= 16(1 + 2)

Therefore,

16 + 32 as a product of two factors using the GCF and the distributive property is 16(1 + 2)

Technology has changed the way that people move, live, and work. Now, technology is changing the way that people receive and react to news stories. News has become a community affair, instead of a job in the hands of the powerful news editors. Through the Internet, people can search for opinionated or unbiased news on just about every topic under the sun. Today, the powerful are not the news editors but the news bloggers. A Web log, or blog, is a space for a person to write down his or her ideas, thoughts, feelings, or even news. Many people in the U.S. have personal blogs, in which they share parts of their lives with total strangers around the world. Now, blogs are becoming increasingly important in the world of news. Reporters caught in the thick of battle can immediately post their thoughts and feelings on blogs. Amateur writers can become instant celebrities from their focus on a particular news-worthy subject. So what are these blogs doing to news? Simply put, they are personalizing news. Blogs are making it easier and faster for readers and Internet surfers to get a behind-the-scenes look at a story. Blogs are also making it easier for people to start conversations about news events, whether that is through comments made about a particular entry or a message board attached to the blog. The Internet in general has allowed people the opportunity to really bring news into their lives. Blogs are just one more way for people to connect to a news story. Unfortunately, blogs have their problems. If they are not attached to a well-known news Web site, like Reuters, CNN, or even your local paper, the blogs are often not fact-checked. Blogs are often more about a person's opinion about an event or a personal attachment to an event or story. They are less about the straight facts and more about the personal element of the story. People have to be very careful when reading blogs not attached to familiar news companies. The right blog can be an enjoyable and personal way to experience news and understand what is going on in the world. From a reporter on the campaign trail to a family living in Iraq, readers can find out many different views on a wide variety of stories. Blogs are just one more way for people to personalize and identify with news they might not otherwise see or hear about. Take a few minutes to find a blog that fits your interests. You might be surprised at what you learn!Select the correct answer.Which of the following statements supports the idea that the blogs are not always trustworthy?A."The Internet in general has allowed people the opportunity to really bring news into their lives."B."News has become a community affair, instead of a job in the hands of the powerful news editors."C."If they are not attached to a well-known news Web site . . . the blogs are often not fact-checked."D."Amateur writers can become instant celebrities from their focus on a particular news-worthy subject."Reset Read 3 integer numbers from the user; these numbers represent the lengths of 3 straight lines.

This short video illustrates this concept: How to determine if the three sides make up a triangle. 2.
