Given:

Php 50.00 is paid for the first 10 kilometers and the addition of Php 5.00 for every succeeding kilometer.

To find:

The total fare (F) for x kilometers.

Solution:

Let x be the number of kilometers and F(x) is total fare.

Number of kilometers cannot be negative. So, x is always greater than 0.

Php 50.00 is paid for the first 10 kilometers.

[tex]f(x)=50.00[/tex] for [tex]0\leq x\leq 10[/tex]

The addition of Php 5.00 for every succeeding kilometer.

[tex]f(x)=50.00+5.00(x-10)[/tex] for [tex]x\geq 10[/tex]

Therefore, the required function is

[tex]\begin{cases}50.00, & \text{ if } 0\leq x\leq 10\\ 50.00+5.00(x-10), & \text{ if } x\geq 10 \end{cases}[/tex].

The number of ways the task of Rearranging the rectangular grid can be done if no two neighboring tiles are the same color is;

P(no two neighboring tiles are same) = 60 ways

We are given;

Number of yellow tiles; n_y = 3

Number of white tiles; n_w = 2

Number of blue tiles; n_b = 1

Now, if no two neighboring tiles can be the same tile Color, it means that;

P(no two neighboring tiles are same) = number of ways when no restriction/((n_y)! × (n_w)! × (n_b)!)

>> P(no two neighboring tiles are same) = 6!/(3! × 2! × 1!)

>> P(no two neighboring tiles are same) = 720/12

P(no two neighboring tiles are same) = 60 ways

Expression = (y + 5,763) - (y - 8)

Simplified expression = 5,763 + 8

Step-by-step explanation:

• Note: The question is incomplete, however, the concluding part is ; write an expression, using integers to represent the difference between the elevations.

We can make y represent the sea level.

Since the highest point of the country is 5,763 feet above sea level, it Means that the expression can be written as;

y + 5,763

Also, we know that the lowest point is 8 feet below the sea level, hence expression can be written as;

y - 8

We can then find the difference(expression) between both elevation.

= (y + 5,763) - (y - 8)

When the expression is further simplified, we'll have;

5,763 + 8

Hi there & welcome to brainly!

Answer:

Step-by-step explanation:

Let the co-ordinates of D be ( x , y )

Let D ( x , y ) be ( x1 , y1 ) and F ( 3 , 5 ) be ( x2 , y2 )

Midpoint of DF = E ( -2 , 2 )

Now, finding the co-ordinates of D :

[tex]\boxed{\sf{ midpoint = (\frac{x1 + x2}{2} , \frac{y1 + y2}{2} ) }}[/tex]

⇒ [tex]\sf{ ( - 2 , 2 ) = (\frac{x + 3}{2} , \frac{y + 5}{2} )}[/tex]

Equating corresponding elements, we get :

[tex]\sf{-2 = \frac{x + 3}{2} }[/tex]                                  

⇒ [tex]\sf{ -4 = x + 3 }[/tex]

⇒ [tex]\sf{ x + 3 = -4 }[/tex]

⇒ [tex]\sf{ x = -4 - 3}[/tex]

⇒ [tex]\sf{x = -7 }[/tex]

Again,

[tex]\sf{ 2 = \frac{y+5}{2} }[/tex]

⇒ [tex]\sf{y + 5 = 4 }[/tex]

⇒ y = 4 - 5

⇒ y = -1

Hence, The co-ordinates of D = ( -7 , -1 )

The value of six eights minus one fourth is 1/2

An expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.).

Example of expression includes; 5x -2 , 5/2 , x +y . When two ore more terms are joined with an operation,we can call it expression.

six eights = 6/8

one fourth = 1/4

Therefore

of six eights minus one fourth

= 6/8 - 1/4

= 6 - 2/8

= 4/8

divide through by 4

= 1/2

Therefore the value of 6/8-1/4 is 1/2

Given:

Three times the square of a number is greater than a second number.

The square of the second number increased by 6 is greater than the first number.

To find:

The system of inequalities represents these criteria.

Solution:

Let the first number be x and the second number be y.

Three times the square of a number is greater than a second number.

[tex]3\times x^2>y[/tex]

[tex]3x^2>y[/tex]           ...(i)

The square of the second number increased by 6 is greater than the first number.

[tex]y^2+6>x[/tex]       ...(ii)

Therefore, the system of inequalities represents these criteria has inequalities [tex]3x^2>y[/tex] and [tex]y^2+6>x[/tex], where x is first number and y is second number.

The system of inequalities represents given criteria are [tex]3x^{2} > y[/tex] and [tex]y^{2} +6 > x[/tex].

Let us take the numbers as x and y respectively.

First number = x

Second number = y

Inequality is the relationship between two expressions that are not equal to one another.

Three times the square of the first number is greater than a second number:

This means, [tex]3x^{2} > y[/tex]

The square of the second number increased by 6 is greater than the first number:

This means, [tex]y^{2} +6 > x[/tex]

Therefore, the system of inequalities represents given criteria are [tex]3x^{2} > y[/tex] and [tex]y^{2} +6 > x[/tex].

The required temperature would be  -6°C at 4:00 pm, which is determined by the expression -3/2 × 4/1.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

At midday, the temperature is 0 degrees Celsius. For four hours, the temperature decreases by -3/2 degrees Celsius per hour.

According to the given condition, we can write the expression as:

⇒ -3/2 × 4/1

⇒ -12/2

Apply the division operation to get the solution

⇒ -6

So, the time at which the temperature goes -6°C  is 4:00 PM.

Therefore, the required temperature would be  -6°C at 4:00 pm.

Step-by-step explanation:

isosceles triangles means that the two bottom angles and sides are equal

therefore, you can set R and T equal to each other:

(15x-31)=(9x+11)

(get x to one side)

15x=9x+42

6x=42

x=7

now you can plug x back into the equations:

15(7)-31

105-31

74

R and T = 74

all triangles' internal angles = 180

therefore you can add the two angles then subtract them from 180

74+74=148

180-148=32

S should be 32 :)
