seeta devi has rs 9 in fifty-paiseand twenty fiv-paise coins. She has twice as many twenty-five paise coins as fifty-paise coins.How many coins of each kind does she have?

Answers

Answer 1

Answer:

50 paise coin = 9

25 paise coin = 18

Step-by-step explanation:

Let :

Number of fifty paise = x

Number of 25 paise = y

50x + 25y = 900 - - - (1)

y = 2x - - - (2)

50x + 25(2x) = 900

50x + 50x = 900

100x = 900

x = 900/100

x = 9

y = 2x

y = 2(9)

y = 18

Answers

Answer:

£4867.2

Step-by-step explanation:

Given data

P= £4500

T=2 years

R= 4%

The compound interest expression

A=P(1+r)^t

substitute

A= 4500(1+0.04)^2

Explanation:

Supplementary angles: Angles that measure up to 180°Write an equation to find x

4x + 10 + x = 180

Group like terms

4x + x + 10 = 180

Add: 4x + x = 5x

5x + 10 = 180

Subtract 10 from both sides

5x + 10 - 10 = 180 - 10

5x = 170

Divide both sides by 5

5x / 5 = 170 / 5

x = 34

The angles are supplementary, which means the angles form a linear pair.
(4x+10)°+x°=180°
5x=170
x=170/5
x=34

A five-gallon bucket was completely filled with water. The bucket has a small leak that causes it to lose 8 fluid ounces of water every 15 minutes. If the leak continues at the same rate, how long will it take for the bucket to become half full? 1 gal = 128 fl oz

Answers

Answer:

600 minutes

Step-by-step explanation:

We start with a bucket that is completely full- it has five gallons of water.

5 gallons of water = 5 (128) fl oz = 640 fl oz

Half of 640 fl oz is 320 fl oz, which is the amount we are looking for.

So, we divide [tex]\frac{320}{8}[/tex] to find how many times it will take for the bucket to become half-full, which is 40 times.

Now, we multiply 40 by 15 minutes, so we get 40 × 15 = 600 minutes

Time for the bucket to become half full is 600 minutes.

Here,

A five-gallon bucket was completely filled with water.

The bucket has a small leak that causes it to lose 8 fluid ounces of water every 15 minutes.

We have to find the time for the bucket to become half full.

What is Number system?

A number system is defined as a system of writing to express numbers.

Now,

A five-gallon bucket was completely filled with water.

The bucket has a small leak that causes it to lose 8 fluid ounces of water every 15 minutes.

Hence, We start with a bucket that is completely full- it has five gallons of water.

So, Amount of 5 gallons of water = 5 * 128 = 640 fl oz

Now, Half of 640 fl oz = 640/2 = 320 fl oz

So, we divide to find how many times it will take for the bucket to become half-full as;

⇒ 320 ÷ 8 = 40

Now, Time is calculated as to multiply 40 by 15 minutes,

⇒ 40 × 15 = 600 minutes

Hence, Time for the bucket to become half full is 600 minutes.

What are some Solutions to the linear equation?: 3x+y=-8

Answers

9514 1404 393

Answer:

  (0, -8), (1, -11), (-1, -5)

Step-by-step explanation:

It is convenient to solve for y and choose values of x.

  y = -3x -8 . . . . . subtract 3x from both sides of the equation

Now, any integer value of x you choose will result in an integer value of y. Often, it is convenient to choose values near zero.

  x = -1, y = -3(-1) -8 = 3 -8 = -5 . . . . solution: (-1, -5)

  x = 0, y = -3(0) -8 = -8 . . . . solution: (0, -8)

  x = 1, y = -3(1) -8 = -11 . . . . solution: (1, -11)

x:48

A straight line will be 180 degrees so 180-132=x

132+48=180

The value of the angle x will be 48° hence correct option will be 48°.

What is an angle?

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.

Given that a line with an angle of 132° since in a single line has an angle of 180° so

Angle x + 132° = 180°

x = 180° - 132° = 48° hence it will be the correct answer.

What is the measure of arc ADC?

Answers

Answer: The answer would be 315 if you are looking for the remaining angle if you're looking for the actual measure of the remaining section of the circumference, then the answer would be approximately 49.481

Step-by-step explanation:

Because the remainder of the circle is the answer you're looking for, you can subtract 45 from 360 and get your answer, whenever you know the measure of one angle, and you are looking for the remaining angle, you can use this strategy.

You already know the angel of the remainder, and you can use this to find the section of the circumference shown. First you need to find the circumfrence, to do this you must use the equation C equals pi radius squared. You put 9 in for the radius and you get approximately 56.55, you then divide this by 360 and get 0.15708333, you then multiply it by the angle you found early, 315. You then should get approximately 49.48125.
