Based on the information, it should be noted that there be 67 adults and 733 students in the auditorium.

Let adults tickets = a

Let students tickets = s

The auditorium at McCaskey East High School in Lancaster, PA has 800 seats. This will be:

a + s = 800 ..... i

Therefore, suppose that the drama club has a goal of making $3400. This will be:

7a + 4s = 3400 ..... ii

From equation i, a = 800 - s.

7a + 4s = 3400

7(800 - s) + 4s = 3400

5600 - 7s + 4s = 3400

Collect like terms

-7s + 4s = 3400 - 5600

3s = -2200

s = 2200 / 3

s = 733

a = 800 - 733 = 67

Therefore, there'll be 67 adults and 733 students.

There are 40128 peoples in the parade route by proportion.

According to the given question.

You can fit 19 people in a 5ft x 5ft square.

Here we need to find the number of peoples in the 10ft x 1 mile parade.

Since, we have to convert miles into feet then,

1 mile = 5280 feet

We know that the parade route is in the form of rectangle.

Also, the process of proportion reasoning involves understanding the multiplicative relationships between rational quantities.

Now we will find the number of peoples by proportions,

Let us consider the number of people in the rectangle as x.

Therefore,

19/25  = x/5280

⇒ (19/25)(5280) = x

⇒ x = 40128

Hence, there are 40128 peoples in the parade route by proportion.

The two lines are parallel, therefore, the two given angles are equal alternate exterior angles.

[tex]14x + 2 = 15x - 3 \text{ / Subtract 14x}\\14x + 2 - 14x = 15x - 3 - 14x\\\to 2 = x - 3 \text{ / Add 3}\\2 + 3 = x - 3 + 3\\\to 5 = x[/tex]

Using the sine ratio, the value of x is: A. 26°.

Sine ratio is:

Sin ∅ = opposite side length / hypotenuse length of a right angle.

Given the following:

Reference angle (∅) = x

Opposite side length = 11

Hypotenuse side length = 25

Plug in the values

Sin x = 11/25

x = sin^(-1)(11/25)

x ≈ 26°

Answer:

The midpoint is (-1, 3)

Step-by-step explanation:

Given M = [tex]\sf \left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} \right)[/tex]

[tex]M=\left(\frac{2+(-4)}{2}, \frac{5+1}{2} \right)\\M=(-1, 3)[/tex]

The length of the rectangle is 12feet and the width is 26feet.

The formula for calculating the perimeter of a rectangle is expressed according to the equation below:

Perimeter = 2(length + width)

If the width is 3 times the next consecutive integer, then;

w = 3(x+1)

l = x

Substitute

102 = 2(x + 3x + 3)

102 = 2(4x + 3)

102/2 = 4x+ 3

51 = 4x + 3

4x = 48

x = 12 = length

For the width

width = 2(x+1)

width = 2(12+1)

width - 26 feet

Hence the length and the width of the rectangle are 12 feet and 26 feet respectively

The expression equivalent to [tex]\frac{12x^{4} }{4x^{16} }[/tex] is 3[tex]x^{-12}[/tex] or 3[tex]x^{4-16}[/tex].that is option C) is correct.

According to the question the expression that we have been given to us is :

               [tex]\frac{12x^{4} }{4x^{16} }[/tex]

Note that we know the property of exponent which states that if teh exponents with same base and different power are divided then the powers are subtracted. That is,  

                 [tex]\frac{x^{m} }{x^{n} } = x^{m-n}[/tex]          (1)

Now using this rule we will evaluate the equation given that is

             = [tex]\frac{12}{4} * \frac{x^{4} }{x^{16} } \\\\[/tex]

First we will divide 12/4 which gives 3 then we will apply the property of exponent to the exponent function which gives,

             = 3 [tex]x^{4-16}[/tex]

The answer of the following fraction which involves ABC is said to be  12:20:25

The transformation of a ratio into a fraction is known as the simple fraction form. In order to convey the relative size of two or more variables, the ratio is utilized. The fraction similarly identifies the components of the total. A:B or a/B are two ways to represent the ratio. As an illustration, the ratio is 12: 15.

Express the ratio in terms of a

a/b = 3/5 (cross-multiply)

3b = 5a (Divide the total both sides by 3)

b= 5/3 a

b/c = 4/5 (cross-multiply)

4c = 5b (divide the total both sides by 4)

c= 5/4 b=5/4×5/3 a=25/12a

then

a:b:c

=a:5/3 a:25/12 a (multiply each part by 12 to clear the fractions)

=12a:20a:25a (divide each part by a)

A Simple Form or simplified form can be defined as When a fraction's numerator and denominator share only one common factor, it is said to be in its simplest form.

Consider the given complex number(2 + i)/(2 - i)

Multiply both numerator and denominator with the complex number (2 + i), and we get

{(2 + i) × (2 + i)} / {(2 + i) × (2 - i)}= {(2 + i) × (2 + i)} / (2² - i²)          

(using the formula (x + y)(x - y) = x² - y²)= {(2 + i) × (2 + i)} / (4 - (-1))= {(2 + i) × (2 + i)} / (4 + 1)= {(2 + i) × (2 + i)} / 5= (2² + 2i + 2i + i²)/5= (4 + 4i + (-1))/5= (3 + 4i)/5

Answer: C

Step-by-step explanation:

Answer: C is the correct answer

Step-by-step explanation:

The length of AC and AB is 19 and 11.

It is the measurement of something from end to end or along its longest side or a measurement of a particular part of something:

We have,

BC = 8

AC = 3x - 8

AB = 2x - 7

We can  make the line as:

A______B______C

We can write as:

AC = AB + BC

3x - 8 = 2x - 7 + 8

Simplify all the like terms together.

3x - 2x = 8 - 7 + 8

x = 16 - 7

x = 9

Now,

AC = 3x - 8 = 3 x 9 - 8 = 27 - 8 = 19

AB = 2x - 7 = 2 x 9 - 7 = 18 - 7 = 11
