The members of the city cultural center have decided to put on a play once a night for a week. Their auditorium holds 600 people. By selling​ tickets, the members would like to raise ​$3,300 every night to cover all expenses. Let d represent the number of adult tickets sold at ​$7.50. Let s represent the number of student tickets sold at ​$4.50 each. If all 600 seats are filled for a​ performance, how many of each type of ticket must have been sold for the members to raise exactly ​$3,300​? At one performance there were two times as many student tickets sold as adult tickets. If there were 360 tickets sold at that​ performance, how much below the goal of ​$3,300 did ticket sales​ fall??

Answers

Answer 1

By using simultaneous linear equation, it can be calculated that-

200 adult tickets and 400 student tickets were sold

In another performance, ticket sale falls $1320 below the goal of $3300

What is simultaneous linear equation?

At first it is important to know about linear equation

Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.

A one degree equation is known as linear equation.

Two or more linear equations, which can be solved together to obtain common solution are known as simultaneous linear equation.

Here, a simultaneous linear equation needs to be solved

Here, d represents the number of adult tickets and s represents the number of student tickets

Their auditorium holds 600 people

d + s = 600 ..... (1)

Price of adult ticket = $7.50

Price of student ticket = $4.50
Total price = $(7.50d + 4.50s)

By the problem,

7.50d + 4.50s = 3300

5d + 3s = 2200 ..... (2)

Multiplying (1) by 3

3d + 3s = 1800.... (3)

Subtracting (3) from (2)

2d = 400

[tex]d = \frac{400}{2}[/tex]

d = 200

Putting the value of d in (1)

200 + s = 600

s = 600 - 200

s = 400

Now,

At one performance there were two times as many student tickets sold as adult tickets.

Total tickets sold = d + 2d = 3d

By the problem-

3d = 360

d = [tex]\frac{360}{3}[/tex]

d = 120

s = 2 [tex]\times[/tex] 120 = 240

Number of student ticket sold = 240

Number of adult ticket sold = 120

Total cost = 240 [tex]\times[/tex] 4.50 + 120 [tex]\times[/tex] 7.50

                 = $1980

Fall in ticket sale = $(3300 - 1980) = $1320

yes; right

yes; obtuse

yes; acute

no

Answers

Classification of given triangle is right angle triangle.

Let's suppose a, b and c are the sides of a triangle.

then we know that sum of 2 sides is always greater than third side.

a + b>c

b + c>a

c + a>b

a = 4.35, b = 5.8 , c = 7.25

a + b>c 4.35+5.8 = 10.15>7.25

b + c>a  5.8 + 7.25 =  13.05>4.35

c + a>b 7.25+4.35 = 11.60>5.8

So now we can say given side lengths are representing sides of a triangle.

It generalizes the Pythagorean Theorem, which states that for a right-angled triangle square of the hypotenuse is equal to the sum of squares of the base and height of the triangle, which is [tex]c^2 = a^2 + b^2[/tex]      

Similarly, It can be observed that

For acute-angled triangle

[tex]c^2 < a^2 + b^2[/tex]    

For Obtuse-angled triangle

[tex]c^2 > a^2 + b^2[/tex]

[tex]a^2 + b^2[/tex] = 18.9225 + 33.64 = 52.5625

[tex]c^2[/tex] = 52.5625

clearly we can see that [tex]a^2+b^2 = c^2[/tex]

So given triangle is Right-angled triangle.

Margaret said the exact product of 602 and 341 is 205,282 . Is she correct prove it by showing an algorithm:

Answers

Yes, she is. The exact product of 602 and 341 is 205,282.

What is algorithm in math?

In mathematics, an algorithm is a process, a description of a series of steps that can be used to solve a problem; however, they are now far more prevalent than that. Although many areas of research (and daily life) use algorithms, long division's step-by-step process is probably the most prevalent example.

To determine the exact product of 602 and 341, both numbers must be multiplied, obtaining the result. To do this, said number can be decomposed, to facilitate the operation and to be able to corroborate the accuracy of the result.

So, we can multiply 602 by 300, plus 602 by 40 and 602 by 1, and add the results.

Therefore, since 602 times 300 is equal to 180,600 (602 x 300 = 180,600); that 602 times 40 is equal to 24,080 (602 x 40 = 24,080); and since 602 times 1 is equal to 602, all those values must be added.

So 180,600 plus 24,080 equals 204,680. And in turn, 204,680 plus 602 equals 205,282. Therefore, the proposed result is correct.

much does each T-shirt and each hat cost? Write a system of equations that can be used to solve the problem.

Answers

The cost of each T-shirt and each hat is $20 and $12 respectively.

Step-by-step explanation:

As given in question that Skyler buys 8 T-shirts and 5 hats for $220.

The next day, he buys 5 T-shirts and 1 hat for $112.

We have to find the cost of T-shirt and hat each.

Let the cost of T-shirt and hat is x and y respectively.

According to the question,

8x + 5y = 220          ............(i)

5x + 1y = 112             ............(ii)

Multiply by 5 in eq. (ii)

25x + 5y = 560        ............(iii)

Now subtract eq. (iii) - eq. (i)

25x + 5y = 560

- 8x + 5y = 220

17x = 340

[tex]x = \frac{340}{17}[/tex]

∴ x = 20

Put the value of x in eq. (ii)

5 x 20 + y = 112

100 + y = 112

y = 112 - 100

∴ y = 12

Hence the cost of each T-shirt and each hat is $20 and $12 respectively.

What is a Linear Equation ?

If an equation is written in the form ax + by + c=0, where a, b, and c are real integers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero, then it is said to be a linear equation in two variables.

Examples of two-variable linear equations are 10x+4y = 3 and -x+5y = 2.

Such an equation has a pair of numbers as its solution, one for x and one for y, which further equalises the two sides of the equation.

A specific point on the graph represents the solution of a linear equation in two variables, ax+by = c, where the total of these two values will equal c when the x-coordinate is multiplied by a and the y-coordinate by b.

Basically, there are infinitely many solutions to a linear equation with two variables.

Answer: To find the tip amount in dollars for each order, you need to multiply the total bill amount by the tip percentage.

For the first order of 4 dishes, the total bill amount is $8 per dish * 4 dishes = $<<8*4=32>>32.

The tip amount is $32 * 20% = $6.40.

For the second order of 6 dishes, the total bill amount is $8 per dish * 6 dishes = $<<8*6=48>>48.

The tip amount is $48 * 14% = $6.72.

For the third order of 7 dishes, the total bill amount is $8 per dish * 7 dishes = $<<8*7=56>>56.

The tip amount is $56 * 11% = $6.16.

So, the tip amounts from least to greatest are $6.16, $6.40, and $6.72.

Therefore ,the volume of the block after cutting out the smaller cubes is  (8/25 cm^2)

What is volume ?

Any three-dimensional solid's volume is just the amount of space it takes up. A cube, cuboid, cone, cylinder, or sphere can be one of these solids.

Volumes vary depending on the shape. We have examined different three-dimensional objects and shapes in geometry, including cubes, cuboids, cylinders, cones, and more. We will learn how to calculate the volume for each of these shapes.

Here,

volume = (8/25 cm2) represents the block's volume after the smaller cubes have been removed.

First, we must determine the volume of a cube with four or five centimeter sides, which is:

V = (4/5 cm)^2 = (16/25 cm^2)

The volume of each of the eight smaller cubes that was removed must now be subtracted.

v = (1/5 cm)^2 = (1/25 cm^2)

After the smaller cubes are removed, the block's volume is:

V - 8v = (16/25 cm^2) - 8*(1/25 cm^2) = (8/25 cm^2)

Ann has 30% less money than mary, and jessica has 70% more money than mary. If the three of them have a total of $102, how much money does each girl have individually?.

Answers

If Ann has 30% less money than mary, and jessica has 70% more money than mary and If the three of them have a total of $102, then Ann has $50.7, Mary has $51 and Jessica has $51.7

What is meant by percentage?

A % is a quantity or ratio that, in mathematics, represents a portion of one hundred. It can be stated as a decimal or a fraction and is frequently represented by the sign "%". 50%, for instance, can be written as 0.5 or 1/2. A component or proportion of an entire is represented using percentages. For instance, if a student receives a 75% on an exam, it indicates that they correctly answered 75 out of 100 questions individually. Percentages are often used in everyday life to represent changes such as a rise or fall in pricing, an increase or reduction in population, or a growth or drop in sales. Percentages may be determined in mathematics using a variety of formulae and ideas including proportions, ratios, and decimals.

How to solve?

Ann has 30/100 * $x = $0.3x less money than Mary

Jessica has 70/100 * $x = $0.7x more money than Mary

Mary, Ann and Jessica have a total of $102

Mary + Ann + Jessica = $102

Mary + (Mary - $0.3x) + (Mary + $0.7x) = $102

3Mary = $102 + $0.3x + $0.7x

3Mary = $102 + $1x

3Mary = $102 + $x

3Mary - $x = $102

2Mary = $102

Mary = $102/2 = $51

Ann = Mary - $0.3x = $51 - $0.3x = $50.7

Jessica = Mary + $0.7x = $51 + $0.7x = $51.7

Ann has $50.7, Mary has $51 and Jessica has $51.7.

What is the Isosceles Triangle?

Isosceles triangles are those triangles that have at least two sides of equal measure. We know that triangles are three-sided enclosed polygons and they are classified as equilateral, isosceles, and scalene, based on the length of their sides.

We have,

given the triangle Δwxy,

m∠y = 35°, and

there are two similar sides to the triangle wx ≅ xy,

Properties of an Isosceles Triangle are:

The two sides are congruent with each other.

The third side of an isosceles triangle which is unequal to the other two sides is called the base of the isosceles triangle.

The two angles opposite to the equal sides are congruent with each other. That means it has two congruent base angles and this is called an isosceles triangle base angle theorem.

The angle which is not congruent to the two congruent base angles is called an apex angle.

The altitude from the apex of an isosceles triangle bisects the base into two equal parts and also bisects its apex angle into two equal angles.

The altitude from the apex of an isosceles triangle divides the triangle into two congruent right-angled triangles.

The two angles opposite to the equal sides are congruent with each other.

so, m∠w = m∠y = 35°

The sum of measure of the angles of the isosceles triangles is 180.

so,

m∠w + m∠x + m∠y = 180

35 + 35 + m∠x = 180

m∠x = 180 - 70

m∠x = 110°

Hence, the measure of m∠x is 110°.

if a:3=12:a, calculate the positive of a

Answers

When a:3=12:a, then the positive of a will be 6.

Given, the  following quadratic equation

a : 3 = 12 : a

That is,

a/3 = 12/a

By cross- multiplication of the values, we will get

a * a = 12 *3

a ^ 2 = 36

From the above equation, we calculate the square root for the value a.

Therefore, we get the square root of,

a ^ 2 = 36

a = 6 ( as the square root of 36 is 6)

So, we can say that when a : 3 = 12: a the positive of a will be 6
