Based on the number of movies, $12.75 is the constant of proportionality per movie

The given parameters are

Number of the movie tickets = 6

Cost of the movie tickets = 76.50

The constant of proportionality of the movie tickets is calculated as

Constant of proportionality = Cost of the movie tickets/Number of the movie tickets

Substitute the known values in the above equation

So, we have

Constant of proportionality = 76.50/6

Evaluate the quotient

So, we have

Constant of proportionality = 12.75

Hence, the constant of proportionality per movie is $12.75

The slope of a line perpendicular to line E is -(5/3).

Given:

Line E passes through the points (-3, 4) and (2, 7).

Slope of line E =  [tex]\frac{y_{2}-x_{1} }{x_{2}-x_{1} }[/tex]

                         =  [tex]\frac{7-4}{2-(-3)}[/tex]

                         =  [tex]\frac{3}{5}[/tex]

So, the slope of a line perpendicular to line E will be the negative reciprocal of the slope of line E i.e. -(5/3).

Therefore, the slope of a line perpendicular to line E is -(5/3).

Answer:

Step-by-step explanation:

Let L and W be the length and width of a triangle.

Rectangle perimeter (Px) = 2L + 2W, where x is triangle a or b.

Rectangle A: La = 5Wa  [The length of Rectangle A is 5 inches more than its width.]

Perimeter Rectangle A:  Pa = 2La + 2Wa

Substitute L = 5Wa:  

Pa = 2La + 2Wa

Pa = 5Wa + 2Wa

Pa = 7Wa

Perimeter Rectangle B:  Pb = 17   [The perimeter of Rectangle B is 17]

Pb = 17

Difference between Pa and Pb:  Is it  < 9?

See the attached table.  The perimeters of rectangle A are computed for each of the answer options that define the width.  Length (rectangle A) is 5 inches more than the width.  The perimeter is 2*Length + 2*Width, and shown as Pa.

The perimeter of rectangle b is 17, shown as Pb on the table.  The last column of the table is the absolute value of the difference of Pa and Pb.  If it is less than 9, the cell is green (it is a possible integer value for the width of rectangle A),  Red mean it does not meet the "less than 9" requirement,  One cell has the difference as 9.  The problem states "less than 9," so it does not meet the requirement.

The value of her investment at compound interest after 4 years will be £8934.34.

What is compound interest?

Compound interest is the adding of interest to the principle sum of a loan or deposit, or interest on interest plus interest. It is the outcome of making an investment interest, or adding it to the lent assets, rather than repaying it out or requesting return from the borrower, so that interest is received on the principle sum plus previously accrued interest in the next month. In finance and economics, compound interest is the norm. Compound interest differs from simple interest in that previously accrued interest is not added to the main amount of the current month, resulting in no compounding. The simple annual interest rate is calculated by multiplying the interest amount per period by the number of periods per year.

Given,

Principal (P) = £8000

Rate of interest (r) = 2.8% compound interest p.a.

Time (n) = 4 years

Then, according to compound interest compounded annually,

Amount = P(1+r/100)ⁿ

             = 8000(1+2.8/100)⁴

             = 8000(102.8/100)⁴

             = 8934.34

Hence, the value of her investment at compound interest after 4 years will be £8934.34.

Zander downloaded a total of 19 Songs and 8 Games.

In the given question, it is stated that Zander's downloads had a combination of 30 games and songs in which he downloaded 8 songs more than games. The equation representing the given situation is g + (8 + g) = 30. Here, g represents Games, and (g+8) represents songs.

Now, to find out the number of games and songs, we need to calculate the value of g by the equation.

=> g + (8 + g) = 30

=> 2g + 8 = 30

=> 2g = 22

=> g = 11

We get value of g = 11, So, downloaded games will be 11 and songs will be 19

Hence, the number of Games and Songs will be 11 and 19 respectively.

Step-by-step explanation:

4/15

Based on the concept of fraction, 80p is equivalent to 4p/15p as a fraction of £3.

Fraction is a term that is used to describe the portion or part of the whole thing.

Generally, the term fraction represents the equal parts of the whole. A fraction has two parts, namely numerator and denominator.

In this case, to find the fraction of 80p as a fraction of £3, we divide 80p by £3.

Since there are 100 pence in 1 pound the fraction can be expressed as 80p/£3.

To simplify the fraction divide both the numerator and the denominator by 10:

80p/£3 = 8p/30p

Simplifying further both the numerator and the denominator can be divided by 2:

8p/30p = 4p/15p

Therefore, in this case, it is concluded that 80p is equivalent to 4p/15p as a fraction of £3.

A cucumber seed needs to be planted 1 inch deep for optimal growth. the plant grows an average of 3 inches every 2 weeks. then the slope in the situation is 2

How do you find the slope of a line?

We need to find the ratio of the difference between the y-coordinates and x-coordinates of the two points, that form the line. The resulted value is the slope of the line. It shows the rise of the line along the y-axis over the run along x-axis.

since seed planted 1 inch deep then y1 = -1 and initial x1 =0

the plant grow an average of 3 inches every 2 weeks then y2 =3 and x2=2

putting in the formula

slope= y2 -y1 /x2 -x1

       = 3-(-1)/2-0

      = 4/2

Using  division we can infer that 50 pages will not be enough.

Division is one of the four basic arithmetic operations, or the process by which two numbers are added together to produce a new number.

Timmy has 810 stamps.

Now each page can hold 16 stamps and he has 50 pages.

Now we will divide 810 by 16 to calculate the number of pages required to put all the stamps.

∴ 810 ÷ 16 = 50 remainder 10.

Therefore after completing the 50 pages there are 10 stamps left.

We use this number to find x.

The inequality that represents the number of minutes of calls made in the United States and in France, can be presented as follows:

An inequality expresses the relationship between two or more values that are not equal.

The value of the calling card = $25

The cost of calls made in the United States = $0.10

Cost of calls made in France = $0.25

The number of minutes that can be used for calls in the U.S. = x

The number of minutes that can be used for making calls in France = y

The duration of calls that can be made in the United states is therefore:

[tex]x_{max} = \dfrac{\$25}{\$0.10} = 250[/tex]

The inequality that represents the number of calls that can be made in the United States is therefore: 0 ≤ x ≤ 250

The duration of calls that can be made in France with the $25 calling card is therefore: [tex]y_{max}=\dfrac{\$25}{\$0.25} = 100[/tex]

The inequality that represents the number of minutes the calling card can be used in making calls in France is: 0 ≤ y ≤ 100

The solution of the given inequality is:

x ≥ 1.

And the graph on the number line can be seen in the image at the end.

The inequality we want to solve and graph is:

-6x + 5 ≤-1

To solve this, we need to start by isolating the variable x in one of the sides, we will get:

-6x + 5 ≤-1

-6x ≤-1 - 5

-6x ≤ -6

Now we can divide both sides by -6 to get:

x ≥ 1.

Then the graph will be like the one below. You need to have a closed dot on x = 1 (because that is a solution to the inequality) and then shade all the region to the right of x = 1, because x also can be larger than 1.
