Step-by-step explanation:

Given that, the cost of a ticket = t and

cost of a box of popcorn =  p.

Total members in the team = 13

As each team member buys 1 ticket and 2  boxes of popcorn, so, the amount spent by one member, [tex]C_1 = t+2p[/tex]

So, the total amount that the team spent [tex]= 13C_1[/tex]

(a) So, the first expression, representing the total amount spent by the team, is

[tex]13\times (t+2p)\cdots(i)[/tex]

On simplification, the second expression, representing the total amount spent by the team, is

[tex]13\timest + 13\times (2p)[/tex]

[tex]=13t+26p\cdots(ii)[/tex]

(b) The expression from the equation (i) represent the total amount spent as 13 times the expenses of one member, while equation (ii) is the sum of two terms where the first term, 13t, represents the total amount spent for buying the ticket and the second term, 26p, represents the total amount spent for buying popcorn

Answer:

The measure of ∠JKL is 65°

Step-by-step explanation:

Consider the provided diagram.

We need to find the degree measure of ∠JKL.

It is given that ∠JKM=45° and ∠MKL=x°

Also it is given that the measure of angle JKL can be represented using the expression 3x + 5.

Thus ∠JKL=3x+5

From the figure it can be concluded that ∠JKL is equal to the sum of ∠JKM and ∠MKL

This can be written as:

∠JKL = ∠JKM+∠MKL

Substitute the respective values in the above equation.

3x+5 = 45+x

Subtract x and 5 from both the sides.

3x+5-x-5 = 45+x-x-5

2x = 40

x = 20

Thus, the measure of ∠MKL=20°

Substitute the value of x in ∠JKL = 3x+5.

∠JKL = 3(20)+5

∠JKL = 60+5

∠JKL = 65

Hence, the measure of ∠JKL is 65°

Answer:

2x + 4y = 110

Step-by-step explanation:

Let

The quantity of small tables = x

The quantity of large tables = y

The smaller tables can fit 2 people, the larger tables can seat 4 people.

Equation that describes the relationship between the quantity of small tables and the quantity of large tables, assuming exactly 110 people need seats.

Number of people×quantity (small table) + number of people×quantity (large table) = 110

2x + 4y = 110

Answer:

5^9

Step-by-step explanation:

125=5*5*5

125^3=125*125*125

125*125*125=3*(5*5*5)

the answer 5^9

The number as a power of 5 which is obtained by the number 125^3 using the power rule and simplifying is 5⁹.

The power rule states that, when the term is raised with a power which is again raised by another power, then this can be simply written as one power by multiplying both the power.

It has to write the number 125³ as a power of 5. Let the resultant number as a power of 5 is n. Thus,

[tex]n=125^3[/tex]

Rewrite the number with multiples of 125.

[tex]n=(5\times5\times5)^3\\n=(5^3)^3[/tex]

By the power rule, the above expression can be rewritten as,

[tex]n=(5)^{3\times3}\\n=(5)^{9}\\n=5^9[/tex]

Thus, the number as a power of 5 which is obtained by the number 125^3 using the power rule and simplifying is 5⁹.

Answer:

The correct option is;

y = 6

Step-by-step explanation:

The reflection of the figure of a preimage over a line of symmetry will form an image that the same coordinates as the preimage.

The line of symmetry is a line or axis that goes through the geometric figure's center and outlines the division of the the figure into two identical, symmetrical parts

The appearance of the figure on one side of the line of symmetry is a reflection of the image on the other side of the line of symmetry

In the figure included in the question, given that the shape of the figure is a rectangle the line of symmetry will be a line passing through the midpoint of a chosen side and parallel to the side adjacent to the chosen side

Therefore, the lines of symmetry are x = 4.5 and y = 6. Therefore, the most correct of the given options is y = 6.

   Option A will represent the line of reflection.

 A rectangle has two pairs of vertices. If one pair reflects over a line in such a way that it replaces the other pair, line is said to be the line of reflection.

If the pair of points A,B replaces the other pair C,D, line of reflection will be y = 6.

Similarly, the pair of vertices A,C replaces other pair B,D, line of reflection will be x = 4.5.

   Therefore, line given in Option A will represent the line of reflection.

[tex]-\frac{7}{25}[/tex]

Step-by-step explanation:

Value of given trigonometric ratio is equals to  [tex]cos (2x) = \frac{7}{25}[/tex].

" Trigonometric ratio is defined as in the right triangle the ratio which represents the relation between sides of a triangle with acute angle of a triangle."

Identity used

[tex]sin^{2} x +cos^{2} x =1\\ \\cos (2x) = cos^{2} x - sin^{2} x[/tex]

According to the question,

Given value of trigonometric ratio,

[tex]sin x = \frac{-3}{5} \\\\cosx < 0[/tex]

Substitute the value of [tex]sin x[/tex] in the above identity of trigonometric ratio,

[tex](\frac{-3}{5} )^{2} + cos^{2} x=1\\\\\implies cos^{2}x = 1- \frac{9}{25}\\ \\\implies cos x = \sqrt{\frac{16}{25} } \\\\\implies cos x = \frac{-4}{5} , cos x < 0[/tex]

Substitute the value of [tex]sin x[/tex] and [tex]cos x[/tex]  the trigonometric identity ,

[tex]cos (2x) =( \frac{-4}{5})^{2} - ( \frac{-3}{5})^{2}\\\\\implies cos (2x) = \frac{16}{25}- \frac{9}{25} \\\\\implies cos (2x) = \frac{7}{25}[/tex]

Hence ,  value of given trigonometric ratio is equals to  [tex]cos (2x) = \frac{7}{25}[/tex].

In stand collection, Stan owns less than 9 cards.

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.

Let x represnets the number of Kyle's cards and y be the number of Stan's cards.

We know that Kyle has 22 more cards than 3 times the number of cards that Stan owns, so:

k = 3s + 22 equation (1)

We also knows that together, they own less than 58 cards, so:

k + s < 58 equation (2)

Replace (1) in (2) and solve for :

s + 3s + 22 <58

s <58

Hence, Stan owns less than 9 cards.

Answer:

$25.97

Step-by-step explanation:

You want to find 70% of $35.00 because there is a 30% markdown meaning 70% of the original price. 70% is the same as 7/10.

to get the price after markdown multiply $35.00 by 7/10 which equals $24.5

Multiply $24.5 by .06 to get the sales tax which is $1.47

So the sales tax is $1.47 and the price after markdown is $24.5 so take the sum of both. $1.47 + $24.5 = $25.97

The cost of Tyler's jacket is $23.03.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, Tyler bought a jacket regularly priced $35.00.

With a 30% markdown, the cost of jacket is

30% of 35

= 30/100 ×35

= 0.3×35

= 10.5

So, the cost of jacket is 35-10.5=$24.5

Now, sales tax on $24.5

That is, 6% of $24.5

= 6/100 ×24.5

= 0.06×24.5

= 1.47

Cost of jacket is 24.5-1.47

= $23.03

Therefore, the cost of Tyler's jacket is $23.03.
