The cost of the washer based on the total cost of $1,800 of all three items is $442.86

How do represent the cost of the washer?

If we assume that the cost of the washer is x, based on that we can determine the cost of the refrigerator and the dryer while deriving from the cost of the washer as denoted below:

cost of washer=x

The cost of the refrigerator is $250 more than the cost of washer i.e. x+250

cost of dryer=0.5*x

cost of dryer=0.5x

total cost=x+x+250+0.5x

total cost=3.5x+250

total amount spent=1800

1800=3.5x+250

1800-250=3.5x

1550=3.5x

x=1550/3.5

x=$442.86

Answer:The answer would be 6a(4b4 +2b3 -3b2)

Step-by-step explanation:All you have to do is take 6a out of each number and put the 6a outside of parenthesis and put the rest of the equation in parenthesis.

Answer:

Step-by-step explanation: These two angles are congruent because most of the points are opposite of each other. For example Angle R is congruent to Angle V and Angle T is congruent to Angle U. Another thing about vertical angles is that they must always equal each other.

The number of employees decreased by 18 percent

The formular for percent decrease is

old value-new value/old value × 100

Given the values of the volume and radius, the height of the cone is 15 inches.

A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.

The volume of a cone is expressed as;

V = (1/3)πr²h

Given the data in the question;

Plug in the given values and solve for h.

V = (1/3)πr²h

h = 3V / πr²

h = ( 3 × 405π in³ )/( π × (9in)²

h = ( 3 × 405 in³ )/( 81 in² )

h = ( 1215 in³ )/( 81 in² )

h = 15 inches

Using proportions, it is found that:

a) 36 pages should be of advertising and 12 pages should be of news stories.

b) 20 pages should be of retail advertising, 12 pages should be of national advertising and 4 pages should be of classified advertising.

c) $450,000 was earned by retail advertising, $270,000 was earned by national advertising and $90,000 was earned by classified advertising.

d) You will receive a bonus of $14,400 for last year's sales.

A proportion is a fraction of a total amount, and equations can be built to find the measures using a rule of three, that can be either direct or inverse, deriving from proportional relationships.

One example of application is for ratio problems, as fractions of the total amount are built from the ratios, as given in this problem.

For item a, we have that three times as much advertising as news stories are needed, hence 3/4 of the 48 pages are advertising, hence:

3/4 x 48 = 0.75 x 48 = 36.

Hence:

The remaining 12 are of news stories.

For item b, from the ratio of 5 to 3 to 1, we have that:

Hence:

In item c, from the same ratio as above, the advertising values are found as follows:

For item d, the bonus is calculated as follows:

1/50(450,000 + 90,000) + 1/75(270,000) = $14,400.

Answer: 26.78 27.08 27.8 27.88

Step-by-step explanation:      

1: Using a Place Value Chart, compare the whole numbers in your list of decimals.

2: Set up a table for the remaining numbers.

3: Transfer the decimals from your math problem into the table.

4: Compare the digits in the tenths column of the table

5: Compare the hundredths column (2 to the right of the decimal point).

6: Examine the digits in the thousandths column.

7: Order the numbers from least to greatest.

- 27.08 - 2nd because 0 is the least/lower number than 8 (tenths value)

- 27.88 - 4th because there are two numbers after the decimal which are greater than the others (tenths & hundredths value)

- 27.8 - 3rd because there is only one number after the decimal (tenths value)

- 26.78 - 1st because 6 is the least number than 7 (tens value)

Explanation in words (Short Form)

- Using the place value chart I can count the lowest number in the tens value that will be the first least number. I will progress my way up until I will eventually find the least to greatest numbers because of there decimal points and numbers after the decimals.

Answer:

(V - U) - 10

Step-by-step explanation:

Using the numeric value of functions, it is found that:

To find the numeric value of a function, we replace each instance of the variable by the desired value.

The formula for the velocity is given as follows:

[tex]v = 8\sqrt{h}[/tex]

In which h is the height.

For this problem, we have that the height is of h = 9.8, hence:

v = 8sqrt(9.8) = 25 feet per second.

The holder was running at a rate of 25 feet per second.

Then, in two seconds, the distance is given as follows:

d = 25 x 2 = 50 feet.

The pole vaulter will run 50 feet in 2 seconds.

Given the central angle and radius of the sector, the area of the shaded region is 28.26cm².

A sector is simply a part of the area of a circle bounded by the central angle and its intercepted arc. The area of a sector is expressed as;

A = (θ/360) × πr²

Given the data in the diagram;

To determine the area of the shaded region, plug the given values into the formula above and solve for A.

A = (θ/360) × πr²

A = (90/360) × 3.14 × (6cm)²

A = (1/4) × 3.14 × 36cm²

A = 3.14 × 9cm²

Red 5 is both a red number and an odd number. This means that if B or O are picked, Red 5 will be picked as it is an odd number.

If the event calls for R or E to be picked as well, Red 5 will also be picked as it is Red. If event O' is picked, then Red 5 will be picked again because it is odd.

On 50th day she needs to buy new bags of rice.

A sequence is defined as an arrangement of numbers in a particular order.

Sequence: 0.4, 0.8, 1.2, 1.6,......20

a=0.4, d=0.4, a_n= 20

Now,

we have to find in how many days 20 pounds rice will ends

So,

a_n= a + (n-1 )d

20 = 0.4 + (n-1) * 0.4

19.6 = (n-1)0.4

19.6/0.4= n-1

49 = n-1

n= 50

The distance that the plane flies between the two cities is 2475 miles.

Velocity is the rate of distance covered per time. Velocity could be average or instantaneous.

For example, if a car drives 50 meters for 10 seconds and it is constant then 50/10 = 5 meters/second will be the velocity.

Time taken = distance covered / velocity

In the first case ;

Time taken = 5 hour.

Velocity = V(Let's say)

Distance covered = x

So,

5 = x/V

x = 5V

Now,

In the second case ;

Velocity = V - 99 (99 slower to first)

Time taken =  6 hours and 15 minutes = 6.25 hour

Distance covered = x

So,

6.25 = x/(V - 99)

x = 6.25V - 618.75

By equating

6.25V - 618.75 = 5V

1.25V = 618.75

V = 495 miles / hour

Now,

x = 5(495) = 2475 miles.

Hence "The distance that the plane flies between the two cities is 2475 miles".

Step-by-step explanation:

Attempt factorization by grouping

(((6•(a^4))•b)-((10•(a^3))•(b^2)))-((2•3a^2)•b^3)

(((6•(a^4))•b)-((2•5a^3)•b^2))-(2•3a^2b^3)

(((2•3a^4) • b) -  (2•5a^3b^2)) -  (2•3a^2b^3)

6a^4b - 10a^3b^2 - 6a^2b^3  =  2a^2b • (3a^2 - 5ab - 3b^2)

Pull out the leading term and put it with the original equation
