The time taken by Sonia to mow 2.5 acres of land with push mower is 3.125 hours .

According to the question we have been given that

    Time taken by push mower to mow 1 acre land = 1.25 hours

     Time taken by Gas mower to mow 1 acre land = 35 minutes

We need to find how many hours Sonia take to mow 2.5 acre of land with push mower.

To find this we will use unitary method. That is

                    1 acre = 1.25 hours

                    2.5 acre = 1.25*2.5 hours

                                 = 3.125 hours.

Hence the time taken by Sonia to mow 2.5 acres of land with push mower is 3.125 hours .

The answer of the logarithmic form is -2 .

We have given an equation [tex]log_2\frac{1}{4}[/tex]   ..... (1)

Applying the property of logarithm which is given by [tex]log_xy=\frac{log_ay}{loh_ax}[/tex]  in equation (1) ,we get

     [tex]log_2\frac{1}{4}=\frac{log\frac{1}{4} }{log2}[/tex]                      ..(2)

[tex]log\frac{1}{4}[/tex] can be written as [tex]log1-log4[/tex] using property [tex]log\frac{a}{b} =loga-logb[/tex] whereas [tex]log1=0[/tex]

Then , the equation (2) becomes

       [tex]log_2\frac{1}{4}=\frac{log1-log4 }{log2}\\\\log_2\frac{1}{4}=\frac{0-log4 }{log2}\\\\log_2\frac{1}{4}=\frac{-log4 }{log2}[/tex]

[tex]log4[/tex] can be written as [tex]log2^2[/tex]

The equation (2) becomes

                    [tex]log_2\frac{1}{4}=\frac{-log2^2 }{log2}[/tex]                

   using property [tex]loga^b=bloga[/tex]

Step-by-step explanation:

The perimeter of the polygon is 12.

The perimeter of a closed figure is the sum of the lengths of its outermost sides. It is the sum of the lengths of a polygon's sides. All sides add up to the perimeter.

The distance between the two points A(x, y) and B(x₁, y₁ ).

AB = √ [ (x₁ - x)² + (y₁ - y)² ]

Consider the vertices U ( -1, 4), V (3, 4), W (3, 1).

Then,

UV = √ [ ( 3 +1)² + (4 - 4)² ] = √4² = 4

VW = √ [ ( 3 - 3)² + ( 1 - 4)² ] = √(- 3)² = 3

UW = √ [ ( 3 + 1)² + ( 1 - 4)² ] = √ [ ( 4)² + (-3)² ] = √ [ 16 + 9 ] = √25 = 5

Then the perimeter of the polygon will be:

perimeter = UV + VW + UW

perimeter = 4 + 3 + 5 = 12

Hence, the perimeter of the polygon is 12.

Step-by-step explanation:

The three positive integers are 34, 35, 36

Three positive integers are given as (x-1),x and (x+1)

Sum of these three integers are 105,

As we know the total sum of the three positive integers, we can get the value by adding the three integers to the sum value.

Thus,

(x-1) + x + (x+1) = 105

x - 1 + x + x + 1 = 105

3x + 0 = 105

3x = 105

x = 105/3

x = 35

Then, the integers are (35 - 1) , 35 , (35 + 1)

Therefore, the three positive integers are 34, 35, 36

Taking into account the definition of a system of linear equations, you little brother has 6 dimes.

A system of linear equations is a set of equations that have more than one unknown, appearing in several of the equations but necessarily in all of them. The equations relate the unknowns to each other.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. In other words, the values ​​of the unknowns must be sought, with which when replacing, they must give the solution proposed in both equations.

In this case, a system of linear equations must be proposed taking into account that:

You know that:

The system of equations to be solved is

[tex]\left \{ {{d+n=42} \atop {0.1d + 0.05n=3}} \right.[/tex]

It is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, isolating the variable "n" from the first equation:

n= 42 -d

Replacing this expression in the second equation obtained:

0.1d + 0.05×(42 - d)= 3

Solving:

0.1d + 0.05×42 - 0.05d= 3

0.1d + 2.1 - 0.05d= 3

0.15d + 2.1=3

0.15d= 3 -2.1

0.15d= 0.9

d= 0.9÷0.15

d= 6

The measure of the angles m∠JKL = (10x + 5)° and m∠PLK = (12x - 1)° are 25 degrees and 23 degrees respectively.

Parallel segments are defined as lines on a plane that never meets.

The properties of parallel segments include:

Given the angles;

We can see that the two angles are vertically opposite angles and thus equal.

Then,

m∠JKL  = m∠PLK

substitute the values

10x + 5 = 12x - 1

collect like terms

10x - 12x = -1 - 5

-2x = - 6

Make 'x' the subject of formula

x = 3

But:

m∠JKL = (10x + 5)° = 10(2) + 5 = 25°

m∠PLK = (12x - 1)° = 12(2) - 1 = 23°

Thus, the measure of the angles m∠JKL = (10x + 5)° and m∠PLK = (12x - 1)° are 25 degrees and 23 degrees respectively.

Answer:

This equation has one solution I believe if you substitute the variable 68.3375

Step-by-step explanation:

Using given algebraic equation, Keelan collected 431 tokens.

In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.). Terms comprise expressions.

At least one variable and one operation must be present in an algebraic expression (addition, subtraction, multiplication, division). One such algebraic statement is 2(x + 8y).

You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic statement. Since 6 + 6 equals 12, the variable x in the example above is equal to 6. If we are aware of the values of our variables, we may substitute those values for the original variables before evaluating the expression.

Given,

p=20x+75

p = 8695

8695 = 20x + 75

x = 8695 - 75 / 20

x = 431

Therefore Keelan collected 431 tokens.

The point of discontinuity for y= x²-x-2 / 3 x²-7 x+2 is x= 1/3 and x= 2.

What is discontinuous function?

Mathematics, functions, and applications all place a premium on continuous functions. But not every function is continuous. A function is said to have a discontinuity there if it is not continuous at that point in its domain.

Given,

y = x²-x-2 / 3 x²-7 x+2

It can be expressed in the form of -

⇒ y = (x-2) (x+1) / (3x-1) (x-2)

The function will be undefined if the denominator will be 0

⇒ 3x-1 = 0

⇒ x = 1/3

⇒ x-2 = 0

⇒x = 2

So, we can conclude that the given function will be having points of discontinuity as x = 2, 1/3
