Answer:

J probably

Step-by-step explanation:

When multiplying the rectangle's sides by 1.5 you get the rectangle F.

When multiplying the sides by 1/4 you get G.

When multiplying by 1.25 you get H.

To get J, you would need to muliply 8 by 1.25 and 2 by 2. There is no scale factor that would result in the rectangle ABCD turning into J.  

Answer:

75%

Step-by-step explanation:

Madison got 18 problems right and there's 24 problems in total. The question asks for the percentage of the problems that she answered correctly. So, put the number of questions that she got right and the total number of questions into a fraction and simplify.

18/24=3/4

3/4ths= 75%

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.

A. 6 minutes

Step-by-step explanation:

6 minutes is 1/10 of an hour.

60 minutes is 1 hour.

5,400 minutes is 90 hours.

3 hours is 180 minutes. You can solve this as a proportion:

[tex]\frac{180}{30} =\frac{x}{1}[/tex]

Cross multiply to get 30x = 180. x = 6.

Answer:

-8/3

Step-by-step explanation:

Answer:

because 3 spheres is inside the cylinder and they are placed close together

=> The height of the cylinder is 3 times the diameter

=> the height is 18cm

the volume of the cylinder is 3,14.18.(6/2)² = 508,68

because 3 spheres have the same diameter

=> the volume of 3 spheres is 4.3,14.3³ = 339,12

=> the volume of the cylinder that is left empty is 508,68 - 339,12 = 169,56

Step-by-step explanation:

Answer:

The answer is 508,68

Step-by-step explanation:

Since the volume of the cylinder is equal to the area of the permanent base multiplied in the height

Since the radius of the base is equal to 3 and since the area of its cylinder is equal to

[tex]314 \times 3 \times 3 = 28.26[/tex]

When the height equal to 18

Then the volume equal to

[tex]28.26 \times 18 = 508.68[/tex]

Answer:

The possible coins are:

P = penny = $0.01

N = nickel = $0.05

D = dime = $0.10

Q = quarter = $0.25

H = half dollar = $0.50

We know that Adam has 3 coins in his pocket, and all of them are different, then the money that Adam has can be represented with (A + B + C)

Behn has 3 coins, and all of them are the same, then if his coin has a value X, he has a total of 3*X

We know that Adam has half as much money as Ben, this can be written as:

(A + B + C) = 3*X/2

The easier way to solve this, is to play with different values of X, and see if we can find the values of A, B and C.

For example, if X = $0.10

then:

(A + B + C) = $0.10*(3/2) = $0.15

We can find 3 different value of coins for this equation? No, we cant, so X = $0.10 is also discarded.

if x = $0.50 then:

(A + B + C) = (3/2)*$0.50 = $0.75

Here we could have:

A = $0.50

B = $0.25

then: A + B = $0.75

But we still have the coin C.

If we take X = $0.25 then:

(A + B + C) = (3/2)*$0.25 = $0.375

We could round the right part to $0.40

then the coins in the left part would be:

A = $0.25

B = $0.10

C = $0.05

A + B + C =  $0.25 + $0.10 +  $0.05 = $0.40

This is a strech, but is the only thing we can make with the given problem.

Answer:

24:9 or 24 to 9 or [tex]\frac{24}{9}[/tex]

Step-by-step explanation:

The amount of plums is 24. The amount of apples is 9. So to write the ratio of plums (24) to apples (9), you write 24 to 9. You can either write a colon - 24:9 - a to - 24 to 9 - or as a fraction - [tex]\frac{24}{9}[/tex]. But, you have to write it with plums first.

Answer:

£32.76

Step-by-step explanation:

21/500=0.042

780x0.042 = 32.76

Answer:

Step-by-step explanation:

x=5

y=-5

Hence it lies in 4th quadrant.

x=r cos θ

5=r cos θ  ...(1)

y=r sin θ

-5 =r sin θ  ... (2)

square and add

(5)²+(-5)²=r²(sin ²θ  +cos ²θ  )

r²=25+25=50

r=±5√2

dividing

tan θ=-5/5=-1=-tan 45°=tan (180-45),tan(360-45)

θ=135°,315°

so polar coordinates are (5√2,315°) and (-5√2,135°)

The shape congruent to given figure is Figure 4.

Option D is correct.

Congruent figures have sides that are the same length and angles that are the same measurement. In other terms, two figures are said to be congruent when they are superimposed upon one another. Even when they are flipped or rotated, they perfectly fit on top of one another.

We have a figure which is similar to parallelogram.

First, figure is seems to be rectangle and do not have same unit measurement which is not Congruent.

Now, the second has more width than given figure.

Now, Third figure is also a rectangle and cannot be congruent.

Now, the fourth figure is similar to given figure.
