By using the unitary method, the final cost of Maliyah's bus ticket after the discount and tax was $101.76.

The unitary method involves dividing the original price by the percentage discount and then multiplying the result by the percentage tax to find the final cost.

First, we will find the discounted price of the bus ticket. To do this, we divide the original price of $120 by 100 and multiply by 20 to find the discount amount.

=> $120 / 100 * 20 = $24.

So, the discount amount is $24.

Next, we subtract the discount amount from the original price to find the discounted price.

=> $120 - $24 = $96.

So, the discounted price of the bus ticket is $96.

Finally, we multiply the discounted price by the percentage tax of 6% to find the final cost. To do this, we divide the 6% tax by 100 and multiply by the discounted price.

=> 6 / 100 * $96 = $5.76.

So, the final cost of the bus ticket is

=> $96 + $5.76 = $101.76.

The measure of the missing angle a is 155 degrees.

The sum of angles on a straight line is equal to 180 degrees.

From the diagram;

Since the sum of angles on a straight line is equal to 180 degrees.

Supplement angle to a  + angle a = 180

25° + a = 180°

Solve for a by subtracting 25° from both sides.

25° - 25° + a = 180° - 25°

a = 180° - 25°

a = 155°

Therefore, the measure of angle a is 155°.

In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical phrase with two equal sides separated by an equal sign is called an equation. An example of an equation is 4 + 6 = 10.

Here,

The first equation in the system is given by the total number of attendees:

c + a = 330

The second equation is given by the number of children being 21 times the number of adults:

c = 21a

We can use substitution to find the value of a and then find the value of c. Substituting the second equation into the first equation, we get:

21a + a = 330

Combining the two terms on the left-hand side, we have:

22a = 330

Dividing both sides by 22, we have:

a = 15

So there were 15 adults in attendance at the school play. To find the number of children, we can use the second equation:

c = 21a = 21 * 15 = 315

So there were 315 children in attendance at the school play.

Answer:

q = 4

Step-by-step explanation:

The three angles shown lie on the same straight and are adjacent to each other.

Adjacent angles on a linear segment are called supplementary angles and their sum adds up to 180°

Plugging in the expressions for the three angles we get:
(8q + 1) + 90 + 57 = 180

==> 8q + 1 + 90 + 67 = 180

==> 8q + 148 = 180

==> 8q = 180 - 148

==> 8q = 32

q = 32/8 = 4

A line spectrum refers to a type of spectrum where light is emitted at specific, discrete frequencies. A continuous spectrum, on the other hand, refers to a type of spectrum where light is emitted at all frequencies within a given range.

A line spectrum refers to a type of spectrum where light is emitted at specific, discrete frequencies. The light is emitted in a pattern of individual lines, hence the name "line spectrum." Hot gases or plasmas often produce this type of spectrum, and the lines represent specific energies of electrons in the gas.

An example of a line spectrum is the Hydrogen spectrum, which consists of a series of distinct lines of different colours that correspond to different energies of the electrons in a hydrogen atom.

A continuous spectrum, on the other hand, refers to a type of spectrum where light is emitted at all frequencies within a given range. The light is emitted in a smooth, continuous manner, hence the name "continuous spectrum." This type of spectrum is often produced by hot solid objects, such as the sun, and it represents a continuous range of energies.

The equations for the Piece Wise Graph is:

F(x)  = -1/8x² - 2x -1            -8 ≤ x < -4

           (x + 1) + 2                -4 < x < 4

A piecewise function is one that has several curve parts in its graph. It signifies that it has several meanings based on the input value. A piecewise function, in other words, performs differently depending on the input.

To derive the above equation,

Set a square root function  y = ax² + bx + C

7 = 64a = 8b +c         a = -1/8
5 = 16a - 4b + c          b = -2
-b/2a = -8                   c = -1


So y = -1/8 x² - 2x -1

Absolute Value Function:

Right: y = x + 3
so y = (x+1) + 2

F(x)  = -1/8x² - 2x -1            -8 ≤ x < -4

Step-by-step explanation:

Set the two equation equal to each other and solve for x.

x + 7 = [tex]\frac{3}{4}[/tex] x + 6  Multiply all the way through by 4 to clear the fraction

4(x + 7) = 4( [tex]\frac{3}{4}[/tex] x + 6)  Distribute the 4

4x + 4(7) = 4([tex]\frac{3}{4}[/tex]x) + 4(6)

4x + 28 = 3x + 24             [tex]\frac{4}{1}[/tex] x [tex]\frac{3}{4}[/tex] = [tex]\frac{12}{4}[/tex] = 3   ([tex]\frac{4}{1}[/tex] is another name for 4)  subtract 3x from both sides

4x - 3x + 28 = 3x - 3x + 24

x + 28 = 24  subtract 28 from both sides

x + 28 - 28 = 24 - 28

x = -4

Substitute -4 for x in either of the two original equations and solve for y.

y = x + 7

y = -4 + 7

y = 3

Check

Substitute in -4 for x and 3 for y and see if we get true statements.

y = x + 7

3 = -4 + 7

The  property which states that the product of a number and the sum of two numbers is equal to the sum of the products of the number and each of the two numbers being added. Using this principle, the problem can be broken down into two separate products, (5 √(3) × 3 √(5)) and (5 √(3) × √(15)) + (√(15) × 3 √(5)).  

The first part of the problem can be simplified by combining 5 and 3, which is 15. This leaves 15 √(15). The second part of the problem can be simplified by combining 3 and 5, which is 15. This leaves 15 √(15). Adding the two parts together results in 30 √(15). The √(15) can be multiplied by itself, which is 15. Multiplying 30 by 15 results in 45 √(45).

The simplified expression is 4a⁵ * b³.

Exponents are a way to represent repeated multiplication. The exponent of a number represents the number of times the base is multiplied by itself. For example, 2^3 means 2 multiplied by itself 3 times, or 2 * 2 * 2 = 8.

In general, if the base number is b and the exponent is n, then b^n represents b multiplied by itself n times. This can be written as b * b * ... * b (n times). The exponent can be any positive integer or zero, and the base can be any real number.

Exponents have several properties, including the following:

b^0 = 1 for any non-zero base b.

b^1 = b for any base b.

b^n * b^m = b^(n + m) for any base b and positive integers n and m.

(b^n)^m = b^(n * m) for any base b and positive integers n and m.

b^(-n) = 1 / b^n for any base b and positive integer n.

These properties help simplify and manipulate expressions with exponents.

We can simplify the expression using the properties of exponents and radicals as follows:

^3√32a¹⁰b⁶

= ^3√(2⁵ * 2¹ * a¹⁰ * b⁶) [since 32 = 2⁵ and 2¹]

= ^3√(2⁶ * a¹⁰ * b⁶) [using the property of exponents: a^m * a^n = a^(m+n)]

= 2^2 * ^3√(a¹⁰ *b⁶) [since 2⁶  = 2² * 2⁴]

= 2² * a⁵ * b³ [since (^3√(x))³ = x, and since a^m * b^m = (ab)^m]

= 4a⁵ * b³.

So, the simplified expression is 4a⁵ * b³.

The side lengths of an equiangular octagon are 1, 2, 3, 4, 1, 2, 3, and 4 in clockwise order so area of octagon is 11 + 12√2 square units.

The sides of octagon are 1, 2, 3, 4, 1, 2, 3, 4 as shown in the figure,

The area of the octagon = area of the rectangle - the area of the four right isosceles triangular corners.

A = (lxb) - 1/2[√2×√2 + √8×√8]x2

A = [(3+√2+√8)(1+√2+√8)] -1/2[√2×√2 + √8×√8 + √2×√2 + √8×√8]

The population of a town increased by 1.5% per year from 1995 to 2015.

So, rate of growth is 1.5%.
