the capacity of cylindrical water tank is 539 litres. if its height is 1.4 metres then find the radius of the base.

Answers

Answer:

350m

Step-by-step explanation:

• Capacity= volume/1000

• but we know that the volume of the cylinder is

[tex]\pi {r}^{2}h[/tex]

so substitute it I'm the volume space

• The substitute for

[tex]\pi \: as \: \frac{22}{7} \: and \: h \: as \: 1.4 \: and \: also \: capacity \: as \: 539[/tex]

• 539 = ((22/7)× r²× 1.4)/1000

• when you simplify you get r as 350m

The letters in the word MATHEMATICIAN were put in a box. What is the chance of getting letter A?

Answers

Answer:

3/13

Step-by-step explanation:

There are a total of 13 letters in the word and 3 of them are A’s so 3/13 is the probability of getting an A.

The probability of getting the letter A is given by P ( A ) = 3/13

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the probability of getting the letter A be P ( A )

Now , the word is given as S = { "MATHEMATICIAN " }

The number of letters in the word S = 13 letters

The number of letter A in the word = 3 A's

So , probability of getting the letter A , P ( A ) = number of letter A in the word / number of letters in the word S

On simplifying , we get

The probability of getting the letter A , P ( A ) = 3/13

Hence , the probability is 3/13

Answer:

the radius is 4, it is the same all around, they are similar, all circles are similar

Step-by-step explanation:

you can use Pythagoras's theorem to find the radius. √33 ^2 = 32. the other lengths must be equal because they are radii. therefore they are √16 which is 4.

Which relation is a function?

Answers

Answer:

the third (bottom left) option

Step-by-step explanation:

for every valid value of x there must be exactly one value of y.

the first option is valid only for positive x, but then for every valid x there are always 2 possible y values (a positive and a negative one).

the second option is defined for only one value of x (3), but this x has infinitely many y values.

the fourth option is a circle defined for -r <= x <= r (r being the radius). in this defined interval almost every x has 2 assigned y values (only x = -r and x = r have one y value).

Answer: Θ = π + 2kπ

Explanation:

cosΘ + 1 = 0
cosΘ = -1

Using the unit circle to help, we must determine what value of theta (in radians) makes cosine -1.

On the unit circle, there is only place where cosine is -1, and that is at π.

Since it asks to find all solutions, we use the “+ 2kπ” to account for them. (Let me know if you need an explanation of why this works/what this means.)

What range of weights measured on an analytical balance with a precision of 0.2mg,will round to 2.0g.What is te relative percent precision of these weights

Answers

The range of weights measured on an analytical balance with a precision of 0.2mg,will round to 2.0g is 0.1900 g to 0.2100 g.

What is analytical balance?

The analytical balance is the device which is used to measure the mass or weight of the object with high level of precision.

Even using the analytical balance equipment, you do not get the accurate weight. For the measurement of the 0.2 g the precision level is ±0.1 mg.

For the positive number, the value will be 0.2100 gFor the negative number, the value will be 0.1900 g.

The range of weights measured on an analytical balance with a precision of 0.2mg,will round to 2.0g is 0.1900 g to 0.2100 g.

Answers

Answer:

1. 72 to 56

2. 90 to 70

Step-by-step explanation:

To fill in the blanks you need to find similar ratios,

For the first one, the ratio is 72 and ___,

because 72 is in the 9's column, find out what times 9 equals 72,

9 × ? = 72

Simply divide to find the answer,

72 ÷ 9 = ?

= 8

Now that you know that 9 is being multiplied by 8, multiply 8 and 7 together,

8 × 7

= 56

Hence the answer is 56 for the first blank,

For the second one, the ratio is 90 and ___,

because 90 is in the 9's column, find out what times 9 equals 90,

9 × ? = 90

Once again simply divide to find the answer,

90 ÷ 9 = ?

= 10

Now that you know that 9 is being multiplied by 10, multiply 10 and 7 together,

7 × 10

= 70

Hence the answer is 70 for the second blank,

Paste these images into your answer or describe them and explain the copyright status of each, clearly evaluating how and where you could use each image appropriately. 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 BIn the 1800s, sea otters were hunted for their fur. The fur trade between North America and Europe was booming, and sea otter fur was a popular option because of its thickness. By the mid-20th century, sea otters had been hunted to near extinction. Only 1,0002,000 sea otters were believed to be living in the wild in 1929. Many people thought the species would soon become extinct. However, due to conservation efforts during the second half of the 20th century, sea otter populations recovered. The strengthening of the numbers of sea otters in the wild is often considered to be one of the greatest successes in marine conservation.How do the authors of the two articles address the same topic in these excerpts? Article A highlights the quality of the sea otter's fur while Article B focuses on conservation efforts that have saved the sea otter in recent years. Article A focuses on the characteristics of the sea otter's fur while Article B focuses on sea otter fur being one of the reasons the animal was hunted. Article A includes historical facts about the significance of the sea otter's fur while Article B focuses on the different ways that the population has recovered. Article A focuses on the sea otter's vanity over its fur while Article B focuses on human vanity to hunt and use sea otter fur for coats and clothing. Can I?
