Answer:

Step-by-step explanation:

Depreciation means value falling

10 is the scrap value which means the value that will remain after the product is properly used up.

depreciation for one year will be calculeted through

(original value - scrap value)/ no of years of use

(500 - 10)/3

= 163 is the annual rate of depreciation

If no scrap value is given, then you will simply divide the value by the no. of years of use

b. annual depreciation = 163

original value = 500

500 - 163(x) = worth of the poster after x years

worth remaining after a certain no. of years is also known as net book value.

Adult tickets costs $63.8

Children tickets costs $13.2

Let x represent the adult tickets and y to represent the cost of children tickets

x + y= 77..........equation 1

36x + 17y= 2,297........equation 2

From equation 1

x= 77-y

Substitute 77-y for x in equation 2

36(77-y) + 17y = 2297

2772 - 36y= 2297

-36y= 2297-2772

-36y= -475

y= 475/36

y= 13.2

Substitute 13.2 for y in equation 1

x + 13.2 = 77

x= 77-13.2
x= 63.8

Hence adult tickets costs $63.8 and children tickets costs $13.2

Answer:

Choice a
y = 2x -5

Step-by-step explanation:

The slope-intercept form of a line is y = mx + b where m is the slope and b the y-intercept

The given line has slope = 2

A parallel line will have slope = 2 also

So the only choice is 2x + 5 which is choice a

The measure of PQT = 142.

We know what ray QS bisects angle PQT. If you draw out angle PQT and ray QS you can see that angle PQS is congruent to angle SQT. Because of the definition of angle bisector. This also means that angle SQT is half of PQT. Because of this we know that we can set the measure of PQT equal to 2 times the measure of SQT.

So we can set up and solve the following equation as such:

2(8x-25) = 9x +34

16x - 50 = 9x +34

7x -50 = 34

7x = 84

x = 12

Again I this doesn't seem to be your final answer. To find the answer the measures of each angle you're going to want to plug 12 in for x for one of the angles. So I'll do it for angle SQT.

8(12) - 25

96 -25

71

So the measure of angle SQT should be 71. Therefore since QS bisects PQR, the measure of angle PQS should also be 71. The measure of PQT should be double that which makes it 142.

Side = 13 cm

Step-by-step explanation:

To find the side of the square:

Area = 169 square cm

   [tex]\sf \boxed{\bf Side = \sqrt{area}}[/tex]

             [tex]\sf = \sqrt{169}\\\\ = \sqrt{13*13}\\\\ =13 \ cm[/tex]

According to the question, the given rational expression is as follows:

Expression =  [tex]\frac{x^{2} +8x+16}{x^{2} -2x-24}[/tex]

Simplify the numerator as well as denominator by doing factors which is shown below:

[tex]x^{2} +8x+16=x^{2} +4x+4x+16=(x+4)(x+4)[/tex]

Similarly, denominator factors are as follows:

[tex]x^{2} -2x-24=x^{2} -6x+4x-24=(x-6)(x+4)[/tex]

Now, substituting these values in the given expression, we get:

[tex]\frac{x^{2} +8x+16}{x^{2} -2x-24} = \frac{(x+4)(x+4)}{(x-6)(x+4)}=\frac{x+4}{x-6}[/tex]

Therefore, the final answer for the given expression is [tex]\frac{x+4}{x-6}[/tex].

The rocket moves really fast with high speed.

A projectile that receives thrust from a rocket engine is known as a rocket (from the Italian rocchetto, which means "bobbin/spool"). All of the propellant carried by the rocket is used to create the exhaust from its engine.

In actuality, the absence of an atmosphere in space allows rockets to operate more effectively.

Due to their ability to reach Earth's escape velocity, multistage rockets can reach any maximum altitude. Rockets may produce significant accelerations and are powerful, light, and lightweight when compared to airbreathing engines.

In order for rockets to go forward and function in the vacuum of space, their action-reaction engines quickly discharge exhaust in the opposite direction.

Logarithmic scale: A measurement scale in which the position is marked using the logarithm of a value rather than the actual value.

A logarithmic equation includes a logarithm in the variable x.

An exponential equation is one in which the variable is represented by an exponent. A logarithmic equation is one in which the logarithm of a variable-containing expression is used.

For logarithmic equations, log b (x) = y is equivalent to b^y = x such that x > 0, b > 0 and b is not equal to 1.

In the given problem, b = 2, x = 1/2, and y = -1.

b =2

x = 1/2

y = -1

Substituting the values of b, x and y into the equation b^y = x;

2^(-1) = 1/2

therefore, the value of the given equation log₂1/2=1 is 1/2.

By applying the laws of indices to each of the expression, the simplified expressions are matched as follows:

An exponent can be defined as a mathematical operation that is used to raise a quantity to the power of another and it is generally written as bⁿ.

In Mathematics, laws of indices can be defined as the standard principles and rules that are used for simplifying a mathematical equation or expression that involves powers of the same base.

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

In order to evaluate an expression, you should apply the PEMDAS rule, where operations within the parenthesis are first of all evaluated, followed by exponent, and then multiplication or division from the left side of the expression to the right. Lastly, the operations of addition or subtraction would be performed from left to right.

By applying the laws of indices to each of the expression, the simplified expressions are as follows:

5³ ÷ 5⁻¹ = 5⁽³ ⁻⁽⁻¹⁾ = 5⁽³ ⁺ ¹⁾ = 5⁴     ⇒ 5³ ÷ 5⁻¹ = 5⁴

5³ × 5⁻¹ = 5⁽³ ⁺ ⁽⁻¹⁾ = 5⁽³ ⁻ ¹⁾ = 5²

a⁻ⁿ = 1/aⁿ ≡ 5⁻⁴ = 1/5⁴

since slopes are the same in parallel equations, graph the point (1,3) and go up 3, and left 1. the y intercept should be 6. I went left one because it's a negative slope, so in order for the line to be negative, you'd go left, not right.  y= -3x+6
