The perimeter of a rectangle is 75 cm. Its
3
length is 2 – times its breadth. Find the
4.
length and breadth of the rectangle.

Answers

Answer 1

Answer:

length = 25 cm , breadth = 12.5 cm

Step-by-step explanation:

let the breadth be b then the length = 2b

The perimeter is the sum of the 4 sides and is equal to 75 , then

b + b + 2b + 2b = 75 , that is

6b = 75 ( divide both sides by 6 )

b = 12.5

Then

breadth = 12.5 cm and length = 2 × 12.5 = 25 cm

Write an equation of the line that passes through the points (-4, -2) and (0,6)​

Answers

Answer:

y= 2x +6

Step-by-step explanation:

Slope-intercept form

y= mx +c, where m is the slope and c is the y-intercept.

[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]

Slope

[tex] = \frac{6 - ( - 2)}{0 - ( - 4)} [/tex]

[tex] = \frac{6 + 2}{0 + 4} [/tex]

[tex] = \frac{8}{4} [/tex]

= 2

y= 2x +c

y-intercept occurs at x= 0. Since we are given that the line passes through the coordinates (0, 6), the y-intercept is 6.

Thus, the equation of the line is y= 2x +6.

Step-by-step explanation:

if you subtract the two equations from each other then the 'y' terms will be eliminated:

 2x = -12

 x = -6

solve for 'y':

4(-6) - 3y = 24

-24 - 3y = 24

-3y = 48

y = -16

6x-3y=12
4x-3y=24

Write out, in paragraph form, a plan for completing the following proof.
For example, will you prove triangles congruent? How? By what theorem?
Given:
AR= AQ
RT=QS
Prove:
Angle RAT = QAS

Answers

Congruent triangles have equal corresponding sides and angles

Angles RAT and QAS are congruent

How to prove that angles RAT and QAS are congruent

Given that:

AR= AQ and RT=QS

Subtract QS from both sides of the second equation

RT-ST=QS-ST

The above equation means that:

RS = QT or

RS = TQ

In triangle ARQ,

Angles R and Q are congruent because the base angles of an isosceles triangle are congruent.

So, we have:

Angle R = Angle Q

Also,

Angle ARS is congruent to ATQ.

The above means that:

Side lengths AT and AS are congruent

So, we have:

AT=AS ---- The base angles of an isosceles triangle ATS

Because of the above highlights,

Angle 1 = Angle 3

Add angle 2 to both sides

Angle 1 + Angle 2 = Angle 3 + Angle 2

So, we have:

Angle RAT = Angle QAS

Hence, angles RAT and QAS are congruent

Answers

You can use the fact that two expressions in equality can be considered to be equal to a third variable(not used in given context).

The system of equations that could be graphed to solve the equation given is

[tex]y = \log_{0.5}(x)\\\\[/tex][tex]y = \log_3(2+x)[/tex]

How can we form a system of equations from an equation?

Suppose the equation be [tex]a = b\\[/tex]

Let there is a symbol [tex]c[/tex] such that we have [tex]a = b = c[/tex]

It is because a and b are same measure (that is exactly what a = b means)

and we gave another name c to that measure.

Thus, we have

[tex]a = c\\b = c[/tex]

in addition to  [tex]a = b\\[/tex]

Using the above method to find the system of equations needed

Since the given equation is [tex]log_{0.5}(x) = log_2(2+x)[/tex]

The 2d graphs are usually expressed as [tex]y = f(x)[/tex] on X-Y plane.

Taking the equation's expressions equal to y, we get

[tex]log_{0.5}(x) = log_2(2+x) = y[/tex]

or, we get system of equations as

[tex]y = log_{0.5}(x)\\\\y = log_3{(2 + x)}[/tex]

Their graph is plotted below. The intersection point of both curves is the solution to the given equation as it satisfies both the equations of the system of equations formed from the given equation.

What is the rate of the boat in still water and what is the rate of the current?

Answers

Answer: 2mp

Step-by-step explanation: Let "b" represent the speed of the boat in still water

Let "c" represent the speed of the current

Let "t" represent time

Downstream(same direction) =(b+c)*t

Upstream(against current)=(b-c)*t

(b+c)*3=24

(b-c)*4=16

3b+3c=24....all sides can be divided by 3 =b+c=8

4b-4c=16.....all sides can be divided by 4 =b-c=4

Use Elimination method

b+c=8

b-c= 4 Subtracting

=====

2c=4

find c by dividing both sides by 2. c=2

if c=2, substitute to get b

b+2=8

 -2=-2

======

b=6

Speed of boat in still water =6mph

rate of current=2mp

Write 4:20 in the simplest form

Answers

Answer:

1:5

Step-by-step explanation:

To write 4: 20 in simplest form we have to find the GCF (Greatest common factor)

The GCF of 4 and 20 is 4.

we need to factor each number

(factors of 4 = 1, 2, 4)

(factors of 20 = 1, 2, 4, 5, 10, 20)

and choose the greatest factor that exactly divides both 4 and 20, i.e., 4.

Now we can divide

4: 4 = 1

20 : 4 = 5

Thus, 4: 20 in simplest form is 1:5

[RevyBreeze]

Answer:

1:5

Step-by-step explanation:

4:20 also can be express as 4/20 {fraction}

Find GCF : 4

Thus,

4/4 = 1

20/4 = 5

we can also see that if we cross multiply:

4 × 5 = 20

20 × 1 = 20

[tex]\frac{4}{20}=\frac{1}{5}[/tex]

Therefore, 4:20 in the simplest form is 1:5 or 1/5

One factor of f (x ) = 4 x cubed minus 4 x squared minus 16 x 16 is (x – 2). What are all the roots of the function? Use the Remainder Theorem. X = 1, x = 2, or x = 4 x = –2, x = 1, or x = 2 x = 2, x = 4, or x = 16 x = –16, x = 2, or x = 16.

Answers

To solve the problem we must know about the Remainder Theorem.

What is the Remainder theorem?

According to the remainder theorem, when a polynomial P(x) is divided by (x-t) then the remainder of the division is equal to P(t). If P(t)=0, then the (x-t) is the factor of the polynomial.

The roots of the function are 2, 1, and -2.

Given to us

One factor of f (x) = [tex]4x^3-4x^2-16x+16[/tex] is (x – 2).

What is the quotient of the function?

We know (x-2) is the factor of the function, f(x) = [tex]4x^3-4x^2-16x+16[/tex],

therefore,

[tex]f(x) =4x^3-4x^2-16x+16 = [(x-2) \times quotient] + Remainder[/tex]

As (x-2) is the factor of the function, therefore, the remainder will be zero for the equation,

[tex]\rm quotient=\dfrac{4x^3-4x^2-16x+16}{(x-2)}[/tex]

[tex]\rm quotient=4x^2+4x-8[/tex]

What are the factors of the function?

Solving the quadratic equation,

[tex]4x^2+4x-8=0\\\text{Dividing botht the sides of the equation by 4}\\4x^2+4x-8=0\\(x-1)(x+2)=0\\[/tex]

Hence, the roots of the function are 2, 1, and -2.

Answers

Answer:

$360

Step-by-step explanation:

El sueldo de la persona es igual a un monto de $360

Si tenemos un número y queremos determinar una fracción de este entonces debemos multiplicar la fracción por el número recordando que en la multiplicación de fracciones se obtiene una fracción con numerador la multiplicación de los numeradores y con denominador la multiplicación de los denominadores (si es solo un número entero su numerador es el entero y su denominador es 1), luego se simplifica de manera de obtener una fracción irreductible (fracción donde el numerador y el denominador no tengan términos en común)

Los 7/9 del sueldo es $280, entonces si el sueldo es "x" tenemos que:

7/9*x = $280

x = $280*9/7 = $2520/7

x = $360
