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:

30.6

Step-by-step explanation:

The area of a parallelogram is base * height.

Base = 6.8

Height = 4.5

6.8 * 4.5 = 30.6

Just answering so Adriantan2019 can get brainliest because that was a good answer and I don't remember how to do the area! SORRY! :) Have a great day! :)

Answer:

31.

Step-by-step explanation:

1. Write out the problem.

6w-19 + k; w=8 and k=2

2. Figure out the first part of the problem.

So, if w=8 and 6 and w are next to each other, we should multiply 6*8, which is 48. Next, it says to subtract 19. 48-19=29.

3. Find out what the last part of the problem is.

Since the first part of the problem is 29 and k=2, we should add 29+2=31, which is the final answer.

Hope this helped :)

Answer:

Gina will eat  pound cheese for lunch each day

Explanation

Amount of cheese bought = 1 pound and the amount of cheese used =  pound

So, the remaining amount of cheese

As this  pound cheese is splitting into 5 equal parts, so the amount of each part will be:  ÷ 5 =  ×  =  pound

So, Gina will eat  pound cheese for lunch each day.

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.

Add 1 to both sides of the equation to get 4x = 4.

Divide both sides by 4 and x = 1.

Answer:

x= 1

Step-by-step explanation:

4x-1=3

    +1 +1

4x=4 (divide both sides by 4 to get x alone)

x=1

Answer:

x = 6

Step-by-step explanation:

3 ln x = ln 216

Rewrite 216 as 6^3

3 ln x = ln 6^3

We know that ln a^b = b ln a

3 ln x = 3 ln 6

x = 6

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:

I think the answer is the last one

adjacent side / hypotenuse

Answer:

f(x) = x² - 81 = ( x+ 9)(x - 9) Difference of two squares

g(x) = x+9/x-9

g(x) . f(x) = x + 9/ x - 9 × (x+9)(x - 9)

= ( x + 9)(x +9)

= ( x + 9)²

= x² + 18x + 81

Hope this helps.

Answer:

It will be letter D and A

Step-by-step explanation:

Letter D, because you are saying that is 25 over 100 and letter A because the equation to find a percentage is:

[tex]\frac{X}{Y}= \frac{PERCENTAGE MISSING}{100}[/tex]

X and Y: will be the information that they give so, the equation and answer will be

[tex]\frac{25}{100} =\frac{x}{100}\\\\ \frac{25* 100 }{100} \\\\\frac{2500}{100} \\\\25%[/tex]

Step-by-step explanation:

Since triangles TUS and QRS are similar, if TUS is isosceles then so is QRS. This means that all corresponding proportions are at a constant ratio. So if TS=US, QT=RU and therefore a=7. Hope this helps!

Answer:

a =7

Step-by-step explanation:

The triangles are similar so we can use ratios

10           10

------  = --------

10+a      10+7

Since the numerators are the same, the denominators have to be the same

10+a = 10+7

a = 7

Answer:

2). Volume = 14400 feet³

3). Volume = 157.5 ft³

Step-by-step explanation:

Both the figures given in the sheet attached are a rectangular pyramid and a triangular prism.

2). In this part of the question solid given is in the shape of an rectangular pyramid.

Volume of this oblique pyramid = [tex]\frac{1}{3}(\text{Base})(\text{Height})[/tex]

Here 'B' = area of the base

h = height of the pyramid

Volume = [tex]\frac{1}{3}(25\times 36)\times 48[/tex]

             = 14400 cubic feet

4). Volume of a triangular cone = (Area of the triangular base)×(height)

                                                    = [tex][\frac{1}{2}(\text{Base})(\text{height})]\times {\text{height of the prism}}[/tex]

                                                    = [tex]\frac{1}{2}(7\times 9)\times {5}[/tex]

                                                    = 157.5 ft³

The  solutions of the equation 2x²+7x+3=0 are x=-1/2 and x=-3.

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

The given equation is 2x²+7x+3=0

Two times of x square plus seven times of x plus three equal to zero is the form of quadratic.

We can solve the quadratic equation  2x²+7x+3=0 using factoring

Let us find two numbers whose product is 2x²+7x+3=0 and

whose sum is 7.

We can see that 2x²+7x+3=0

Let us factor by grouping

2x²+6x+x+3=0

2x(x+3)+(x+3)

=(2x+1)(x+3).

x=-1/2 and x=-3

Therefore, the solutions are x=-3 and x=-1/2.

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:

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

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
