The equation will be: 4.65r + 4.95p = 874.80

The total cost of gas will be sum of the individual costs of both the types of gas. Firstly, calculating cost of regular and premium gas followed by forming the equation.

The total cost of regular gas = Amount of regular gas × Cost of regular gas per gallon

The total cost of regular gas = 4.65 × r

The total cost of premium gas = Amount of premium gas × Cost of premium gas per gallon

The total cost of regular gas = 4.95 × p

We are given overall spending = 874.80

Forming the equation -

Total cost of regular gas + total cost of premium gas = overall spending on gas

4.65r + 4.95p = 874.80

Hence, the equation that models the situation is 4.65r + 4.95p = 874.80.

Answer:

Step-by-step explanation:

In order to factor this quadratic, we can use the method of grouping. First, we need to find two numbers that add up to 23 and multiply to 90. The two numbers 18 and 5 satisfy both of these conditions,

since 18 + 5= 23 and 18*5

We can then factor the quadratic as follows:

[tex]\sf 3x^2 - 23x +30[/tex]

we can write it as:

[tex] \sf 3x^2 -(18+5)x + 30 [/tex]

Opening bracket

[tex] \sf 3x^2 - 18x -5x +30  [/tex]

Taking common from each two terms

[tex] \sf 3x(x-6) -5(x-6)  [/tex]

Taking common and keeping remaining in bracket

[tex] \sf (x-6)(3x-5)  [/tex]

Therefore, the quadratic of [tex] \sf 3x^2 - 23x +30  [/tex] can be factored as (3x - 5)(x - 6).

Answer: 24x² + 20x + 4

Step-by-step explanation:

       Area of a rectangle can be found with A = L * W;

               A = L * W

               A = (8x + 4) * (3x + 1)

       Now we can use the "FOIL" method, which is used to multiply binomials.

[F] First ➜ 8x * 3x = 24x²

[O] Outside ➜ 8x * 1 = 8x

[I] Inside ➜ 4 * 3x = 12x

[L] Last ➜ 4 * 1 = 4

       Lastly, we add it all together for our final answer.

24x² + 8x + 12x + 4 = 24x² + 20x + 4

Answer:

24x^2+20x+4

Step-by-step explanation:

Area is length times width.

The length is (8x+4) and the width is (3x+1).

If we follow the formula for the area of a rectangle, then it would be

(8x+4)(3x+1).

Next, you would foil.

Take the first and multiply it by the second equation as follows

8x*3x+8x*1 which would give you

24x^2+8x

Then, you would take the second from the first equation and multiply it with the second equation as well.

4*3x+4*1 which would give you

12x+4

Combine all of it together

24x^2+8x+12x+4

Combine like terms

24x^2+20x+4

That's the area.

Using proportions, it is found that the cost of the 5 t-shirts would be of 564.83 Kronas.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using a rule of three, that can be either direct(cross multiplication) or inverse(line multiplication), deriving from proportional relationships. One example of application of proportions is for currency conversion problems, as multiplication or division operations are applied according to the rates of each coin.

For this problem, we have that 7 t-shirts cost $90.93, hence the cost of a t-shirt in U.S. dollars is given applying the proportion to find the unit rate as follows:

$90.93/7 = $12.99.

The cost of 5 t-shirts will be given by:

5 x 12.99 = $64.95.

Applying the proportion 1 U.S. Dollar = 8.6964 Krona, the cost in Kronas is:

64.95 x 8.6964 = 564.83 Kronas.

The cost of the 5 t-shirts would be of 564.83 Kronas.

The equation that can be used to determine the cost of a bag of potatoes is $31.69 - $4.09 = 4x

The cost of a bag of potatoes is $6.90

From the question, we are to write and solve an equation that could be used to determine x, the cost of a bag of potatoes

From the given information,

Serenity buys milk and potatoes at the store and she pays a total of $31.69

and

She pays a total of $4.09 for the milk

Thus,

The amount she pays for potatoes is $31.69 - $4.09

Also, from the information,

"She buys 4 bags of potatoes that each cost the same amount"

If x represent the cost of a bag of potatoes, then we can write that

$31.69 - $4.09 = 4x

This is the equation that can be used to determine the cost of a bag of potatoes

Now,

Solve the equation for x

$31.69 - $4.09 = 4x

$27.60 = 4x

x = $27.60/4

x = $6.90

Hence, the cost of a bag of potatoes is $6.90

If Katie invested a total of $8000, part at 5% simple interest and  part at 6% simple interest and at the end of one year the investments had earned $454 interest, then she invested $2600 at 5% and $5400 at 6% simple interest

Given,

The total invested amount = $8000

Consider the amount invested at 5% simple interest as x and the amount invested at 6% simple interest as y

Then, the equations will become

x + y= 8000

x = 8000-y

At the end of one year the investment = $454

0.05x + 0.06y =454

Substitute the value of x in the equation

0.05(8000-y) + 0.06y =454

400-0.05y+0.06y =454

0.01y+400=454

0.01y =54

y = 5400

Substitute the value of x in

x + y = 8000

x+5400=8000

x=8000-5400

x=2600

Hence, if Katie invested a total of $8000, part at 5% simple interest and  part at 6% simple interest and at the end of one year the investments had earned $454 interest, then she invested $2600 at 5% and $5400 at 6% simple interest

"There is a much larger preference for English among those who prefer rock", but there is only a little more than 20% of the students who prefer english.

"There is a much smaller preference for math among those who prefer country", but nearly 40% of the students prefer math.

And looking at it, all the subject preferences for all kind of music groups are pretty much evenly distributed.

The solution to the box plot is the percentages for class preference are relatively the same among the different music groups

A box and whisker plot, often known as a box plot, shows a data set's five-number summary. The minimum, first quartile, median, third quartile, and maximum make up the five-number summary.

A box is drawn from the first quartile to the third quartile in a box plot. At the median, a vertical line passes through the box.

It is used when showing the distribution of data points across a selected measure and if the box in a box plot is stretched in one direction or the other, then the data is skewed in that direction.

Given data ,

Let the plot be represented as A

Now , the x axis represents the favorite music type

And , the y axis represents the relative frequency

From the R and B column , the science people is less than mathematics people

From the Rock column , the English people is less than mathematics people
