Three pounds of apples costs $1.09. How much will 11 pounds of apples cost? Round to the nearest cent.

Answers

Answer:

Step-by-step explanation:

Comment

This is a proportion question. That means that the ratios given are equal. There are 4 facts all together. 3 are given, you have to solve for the 4th. The procedure is the same every time.

Equation (proportion)

cost of apples 1.09/ Number of apples (3) = cost of nearly a dozen (x)/Number = 11.

1.09/3 = x / 11                 Cross Multiply

3x = 1.09 * 11                  Combine the right

3x = 11.99                       Divide by 3

3x/3 = 11.99/3      

x = 3.99

Answers

Answer:

135

Step-by-step explanation:

Multiply .15 by 900
0.15 x 900 = 135
Hope this helps :)

Answer:

135

Step-by-step explanation:

To find 15% of a number, we can find 10% first then 5%

10% of 900 is 90 (900 ÷ 10 = 90)5% of 900 is 45 (half of 10% of 90)Therefore, 15% of 900 is 135

We can also turn 15% into a decimal by dividing 15 by 100: 15 ÷ 100 = 0.15 Now, we can treat 'of' as × and do 0.15 × 900 which is 135.

(One soda : 1.50)

Answers

Answer:

1.75 + 1.25 + 1.50 + .75(3) = $6.75 total

Make sure to multiply .75 x 3 because there are 3 bags of chips. That gives you $2.25 in chips to add to the hotdog, popcorn, and soda total.

£245 increased by 25%?

Answers

Answer:

306.25

Step-by-step explanation:

What you need to do is multiply 245 by .25 (the decimal form of 25%). Then you should get 61.25, which is what the increase would be. Then, using the product, add 245 with 61.25 and you'll get the answer.

(Hope this helps)

Answer:

61.25 Euro

Step-by-step explanation:

Hopefully this is right. I'm American so I had to do a little converting with the currency. How you solve it is you multiply 245 by 25 and then divide by 100. Whenever percentage is involved think of the butterfly method.

[tex]x/250=25/100[/tex]

In this problem X is what you're trying to solve for; what the number will be AFTER the increase. The denominator will always be the original amount/price. Then on the other side you put the percentage over 100, since percentages go from 0% to 100%, kinda like quarters.

Let's assume that ,

x is the smaller angle

3x+28 is the larger angle

then,

ATQ,

x + 3x+28 = 180°

4x +28 = 180°

4x = 180°-28°

4x = 152°

x = 38°

putting the value of x in the larger angle

Answers

Answer:

v = √2 +√2iw = -2 -2√3i . . . ("i" is not under either radical)z = 0 -3i

Step-by-step explanation:

A suitable calculator can perform polar to rectangular conversion for you. If you like to do it "by hand", the conversion is ...

  (r; θ) ⇔ r·cos(θ)+ r·sin(θ)i

Your numbers translate to ...

v = √2 +√2iw = -2 -2√3iz = 0 -3i

_____

Additional comment

We aren't often asked to read polar graphs. The concentric rings here are taken to be 1 unit apart. The radial lines are 15° apart. Then the various points are ...

  v = 2∠45°

  w = 4∠-120°

  z = 3∠-90°

As you can see, the TI-84 work-alike in the attachment is able to write and understand numbers in this form. Other calculators treat complex numbers as vectors [magnitude, angle], or as coordinates with a special separator (semicolon) to indicate polar coordinates vs. complex plane coordinates: (r; θ) vs. x +iy

In any event, you need to be careful to understand the units the calculator uses for angles. In the attached, we have set the angle units to degrees. Most spreadsheets default to radians.

Read the excerpts from the two articles on sea otters.Article ASea otters live in the chilly Northern Pacific Ocean and spend almost all their lives in the water. They sleep, hunt, groom, mate, and give birth in the ocean, where they float on their backs on the water's surface. Adult sea otters spend more than a third of their day grooming their fur. This isn't for vanity; it's for survival. Unlike most sea mammals, sea otters do not have an inner layer of fat to protect them from the cold water. These creatures rely on their dense fur to protect them from the low temperatures. Sea otters have one of the thickest furs in all of the animal kingdom. An adult sea otter's coat can contain up to 1 billion individual hairs! These hairs form a protective, waterproof layer, which traps air and provides insulation. It is crucial that a sea otter's fur is kept clean to maintain this insulating layer between the water and their skin.Article BOil spills from off-shore drilling and shipping are also an immense threat to sea otters. Sea otters are dependent on their thick fur to keep them warm. Its unique structure traps air that insulates their bodies from the cold water. When an otter's fur is covered in oil, it can no longer keep the otter warm. This can cause hypothermia and even death. If the otter tries to clean its fur, it will ingest the oil, which is poisonous. In 1989, the Exxon Valdez hit a reef in Alaska. The ship spilled over ten million gallons of oil into the ocean. The U.S. Fish and Wildlife Service believes that anywhere from 4,000 to 10,000 otters died due to this oil spill.How are the authors' points of view different in these excerpts? Article A focuses on the importance of the sea otter grooming its fur, but Article B shows that the sea otter's grooming habits endanger it when the water is not clean. Article A explains that adult sea otters spend more than a third of their day grooming, but in Article B, the author explains that adults spend most of their day caring for their young. Article A highlights the different reasons the sea otter's fur must be clean, and Article B highlights the actual process sea otters use to keep their thick coats clean and healthy. Article A focuses on how the sea otter's fur can harm the animal, while Article B focuses on how the sea otter's fur can protect it from oil spills and other water pollution.
