Answer:

51/12

as a mixed number

4 1/4

Step-by-step explanation:

first you add 8 to 4 which is 12

so the improper fraction would be 51/12

how to turn it in to a mixed number in simplest form

step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 51 by 12 and keep only what is to the left of the decimal point:

51 / 12 = 4.2500 = 4

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.

51 - (12 x 4) = 3

Step 3 - Put Together

Keep the original denominator and use the answers from Step 1 and Step 2 to get this:

4  

   3  

   12  

Step 4 - Minimize

Minimize the fraction part from Step 3 by dividing the numerator and denominator by 3, which is the greatest common factor, to get the final answer. 51/12 as a Mixed Number is:

4  

   1  

   4  

Answer:

[tex]P(x)=x^3-5x^2+2x+8[/tex]

Step-by-step explanation:

If the polynomial has the following zeros: x= 4, x=2, and x=-1, then it must have the following factors which guarantee the polynomial will render zero at the given points:

[tex]P(x)=C (x-4)\, (x-2) \,(x+1)[/tex]

where C is any multiplicative constant. Since there is no other condition imposed on the polynomial, we can adopt a simple constant C = 1 to facilitate our final calculation of writing the polynomial in standard form:

[tex]P(x)=(x-4)\, (x-2) \,(x+1)\\P(x)=(x^2-2x-4x+8)\,(x+1)\\P(x)= (x^2-6x+8)\,(x+1)\\P(x)=x^3+x^2-6x^2-6x+8x+8\\P(x)=x^3-5x^2+2x+8[/tex]

Answer:

The true mean volume of p

aint in each can is greater than or equals to 400ml

Step-by-step explanation:

The symbol of μ represents the mean of a data.

Mean can be defined as the average value of a set of data

Let consider the question.

We know that

μ ≥ 400ml

Where the sign ≥ means "greater than or equals to"

Which means that μ is greater than or equals to 400ml

So the solution is:

1st blank = greater than

2nd blank = equals to

Answer:

Step-by-step explanation:

if DF=20, then:

4x+8+2x-2=20

6x+6=20

6x=14

x=14/6

x=7/3

then

DE=4x+8

DE=4(7/3)+8

DE=(28/3)+24/3

DE=52/3

And

EF=2x-2

EF=2(7/3)-2

EF=14/3-6/3

EF=8/3

Answer:

I think the answer is the last one

adjacent side / hypotenuse

Answer:

81

Step-by-step explanation:

Since angles B and D are opposite each other, they are supplementary.

The value of x is 81°, the correct option is B.

A circle is a round-shaped figure with all points lie in the same plane, the distance between all the points on the circle and the center of the circle is equal.

The line that passes through the center of the circle and has end point on the circumference is called the diameter, the radius is half the measure of the diameter.

A quadrilateral is a polygon with four sides, the quadrilateral are of many types like, trapezoid, parallelogram, rhombus, and square.

When a Quadrilateral is inscribed in a circle, the sum of the angles of the opposite sides of the quadrilateral is equal to 180 degree.

A quadrilateral ABCD is inscribed in a circle.

Angle B measures 121°.

Angle D measures (x - 22)°.

The both angles are supplementary

The equation formed will be

121 + (x -22) = 180°

(x -22) = 59°

x = 81°

Answer:

-5 and 11

Step-by-step explanation:

| 3-x | = 8

absolute sign has two value. POSITIVE and NEGATIVE value

POSITIVE

3-x = 8

x = 3-8 = -5

NEGATIVE

-(3-x) = 8

-3 + x = 8

x = 8+3 = 11

Answer:

x =-5                           x = 11

Step-by-step explanation:

|3-x| = 8

We get 2 solutions to an absolute value, one positive and one negative

3-x =8      3-x = -8

Subtract 3 from each side

3-x-3 = 8-3           3-x-3=-8-3

-x =5                      -x = -11

Multiply by -1

x =-5                           x = 11

Answer:

1) 9 × 2 = 18 cm²

2) 6 cm

3) 9 × 2 × 6 = 108 cm³

Answer:

Base area: [tex]18cm^2[/tex]

Height: 6 cm

Volume: [tex]108cm^3[/tex]

Step-by-step explanation:

Base area:

So the base is the side the right rectangular prism is laying on and in this case it is ABCD and the length and width is 9 and 2 so multiplying that we get [tex]18cm^2[/tex].

Height:

In this scenario of a right rectangular prism any side It is lying on so we will use 6 cm as the height.

Volume:

To find the volume of a rectangular prism you have to use the following formula.

[tex]V=l*w*h[/tex]

The l is length which is 9 cm.

The w is width which is 2 cm.

And the h is height which is 6 cm.

So multiplying all that we get [tex]108cm^3[/tex].

Answer:

441

Step-by-step explanation:

The perimeter of a square garden is 84.

Each side must be equal because it is a square.

[tex]P=4s[/tex]

[tex]84=4s[/tex]

[tex]\frac{84}{4} =s[/tex]

[tex]21 = s[/tex]

Each side of the square garden is 21.

The area of a square is equal to

[tex]s^2[/tex]

[tex]21^2 = 441[/tex]

The area of the square garden is 441.

Answer:

441

Step-by-step explanation:

[tex]P = 4s[/tex]

[tex]84 / 4 = 21[/tex]

[tex]A = L * W[/tex]

[tex]21 * 21 = 441[/tex]

Answer:

y = -3/2 x + 5/2

Step-by-step explanation:

2y = 5 - 3x

y = -3/2 x + 5/2

Answer:

y= -3/2x+5/2

3x + 2y = 5

2y= 5- 3x

y= 5/2 - 3/2x

y= -3/2x+5/2

Answer:

The value of Area of B/Area of A is 0.75.

Step-by-step explanation:

It is provided that:

Consider the diagram below.

The area of a rectangle is:

[tex]\text{Area}=\text{Length}\times \text{Breadth}[/tex]

Compute the area of rectangle A as follows:

[tex]\text{Area of A}=l\times b[/tex]

Compute the area of rectangle B as follows:

[tex]\text{Area of B}=1.25\ l\times \frac{3}{5}\ b=0.75\ (l\times b)[/tex]

Compute the value of Area of B/Area of A as follows:

[tex]\frac{\text{Area of B}}{\text{Area of A}}=\frac{0.75\ (l\times b)}{l\times b}=0.75[/tex]

Thus, the value of Area of B/Area of A is 0.75.

Answer:

[tex] \sf{ \dfrac{ 3}{5}x + 2 = \dfrac{2}{3} x}[/tex]

[tex] \implies \sf{ \dfrac{2}{3} x - \dfrac{3}{5} x} = 2[/tex]

[tex] \red\star \sf{take \: l.c.m \: of \: 3 \: and \: 5 = 15}[/tex]

[tex] \implies \sf{ \dfrac{10x - 9x}{15} = 2 }[/tex]

[tex] \implies \sf{ \dfrac{x}{15} = 2 }[/tex]

[tex] \implies \sf{x = 2 \times 15}[/tex]

[tex] \implies \sf{x = 30}[/tex]

Answer:

x=30

Step-by-step explanation:

3/5x+2=2/3x

So for solving for x you are going to first try to get x on the same side so move 2/3x to the left side of the equal sign. so it becomes 3/5x-2/3x+2=0 then you are going to combine like terms and subtract 2/3x from 3/5x so it becomes 9/15x-10/15x since they have least common denominater which is 15 so it becomes 9/15 and 10/15 then you subtract them so it is -1/15x+2=0 then you are going to move the 2 to the other side of the equal sign so it is -1/15x=-2 then you are going to divide multiply -15 to both sides to get rid of it from the x side so you can isolate it so therefore the answer is x=30

Answer:

Step-by-step explanation:

Pool:

Width = x ft

Length = (x+6) ft

Pool along with walkway:

Width = x + 5 + 5 = (x + 10) ft

Length = x + 6 + 5 + 5 = (x + 16) ft

Total area of the pool with walkway = 950 sq.ft

length * width = 950

(x+16) * (x + 10) = 950

Use FOIL method,

x*x + x *10 + 16*x + 16 *10 = 950

x² + 10x + 16x + 160 -950 = 0   {Add like terms}

x² + 26x - 790 = 0

Answer:

29.4 length and 21.4 width.

Step-by-step explanation:

To fin the dimensions of the pool we need to use the total area of the pool plus the concrete walkway. Lets say that W is the width and L the length. We know that, the walkway has 3 ft wide, this means that the width and length are increased by 6ft (3ft on each side). So, the total
