A rectangle has length 2x+3 and width 7x+9. Write a polynomial in standard form that represents the perimeter of the rectangle. You MUST combine like terms.

Answer:

B

Step-by-step explanation:

A rational number can be expressed in the form

[tex]\frac{a}{b}[/tex] ← where a and b are integers

From the set

3 is rational as it can be expressed as [tex]\frac{3}{1}[/tex]

and [tex]\sqrt{9}[/tex] = 3 ← rational

[tex]\sqrt{2}[/tex], [tex]\sqrt{3}[/tex] and [tex]\sqrt{7}[/tex] ← are irrational numbers

Thus there are 2 rational numbers out of the 5 given, thus

P( rational ) = [tex]\frac{2}{5}[/tex] → B

Answer:

13.91

Step-by-step explanation:

The question lacks the required diagram. Find the diagram attached.

From the diagram the length of the vector along x component is given as:

Vx = Vcos(theta)

theta is the angle between the vector and the x axis

V is the length of the vector

Given

theta = 22°

V = 15

Substitute the given values into the formula above

Vx = 15cos22°

Vx = 15×0.9272

Vx = 13.91

Hence the length of the x-component of the vector is approximately 13.91

Answer:

6/25

Step-by-step explanation:

Answer:

x = -6

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

2(x - 7) = 5x + 4

Step 2: Distribute parenthesis

2x - 14 = 5x + 4

Step 3: Subtract 2x on both sides

-14 = 3x + 4

Step 4: Subtract 4 on both sides

-18 = 3x

Step 5: Divide both sides by 3

-6 = x

Step 6: Rewrite

x = -6

Answer:

x=-6

Step-by-step explanation:

2(x-7)= 5x+4

2x - 14 = 5x+4

-2x         -2x

-14 = 3x +4

- 4           -4

-18= 3x

18/3 = 3x/3

6   = x

Answer:

y = 25x + 8

Step-by-step explanation:

The slope intercept equation has a standard form of;

y = mx + c

Now, we are told that She charges a design fee of $8 for a custom bowling shirt, and sells each shirt for $25 dollars.

And that y represents the total cost and x represents the number of bowling shirts.

Now, since x represents the number of bowling shirts, the cost of x bowling shirts is = 25x

Also, since design fee is $8, it means that total cost = 25x + 8

Writing this in slope intercept form;

y = 25x + 8

Answer:

B, 13 cubic yards.

Step-by-step explanation:

You didn't give a graph, but I'm assuming you had the same question as me (I attached the graph that I had). I took the test and got the right answer.

The recommended amount of mulch for a flowerbed with a radius of 20 feet is 13 cubic yards

The vertex of the graph is given as:

Vertex = (0,0.5)

The equation of the graph is given as:

[tex]y = 0.5 * 1.177^x[/tex]

When the radius is 20 feet, we have:

y = 0.5 * 1.177²⁰

Evaluate

y = 13.02

Approximate

y = 13.0

Hence, the recommended amount of mulch for a flowerbed with a radius of 20 feet is 13 cubic yards

Answer: 360.73

Step-by-step explanation:

When you come across any question that says [a of b] is just saying a × b.

5.5% of x=5.5% × x

-----------------------------------------------------------------

Given

5.5% of x=19.84

Converted into numerical expression

5.5% × x=19.84

Divide both sides by 5.5% (0.055)

x=19.84 ÷ 5.5%

simplify

x=360.73 (rounded)

Answer:

360.7273

Step-by-step explanation:

5.5% of 'x' is 19.84

so, x*5.5/100 = 19.84

or, x*5.5 = 1984

or, x = 1984/5.5

so, x=360.7273(answer)

Step-by-step explanation:

To see if 6 is a factor of 18, we need to take the quotient between 18 and 6 and see if it is an integer, so the correct option is C.

We say that the number a is a factor of b if and only if a divides b.

This means that the quotient:

b/a =  integer number.

Then, to see if 6 is a factor of 18, we need to divide 18 by 6, and see if the quotient is an integer number.

We will get:

18/6 = 3

3 is an integer number, so yes, 6 is a factor of 18.

From this, we can conclude that the correct option is C.

Answer:

since second company salary, $93,600, is more than first company yearly salary of $65000

Second company pays more

Step-by-step explanation:

To check what job pays more we have to compare yearly salary of both the company offer.

_________________________________________________

Yearly salary from one company = 65k = 65000

Weekly salary from another company = $1800

there are 52 weeks in a year

to get yearly salary , we need to multiply weekly salary with 52.

Yearly salary from another company = Weekly salary*no of wees in a year

Yearly salary from another company = 52*$1800 = $93,600

since second company salary, $93,600, is more than first company yearly salary of $65000

Second company pays more

The cylinder is a closed figure which consists of two circular ends. If r is the radius and h is the height of the cylinder, then its surface area is given by :

[tex]A=2\pi rh[/tex]

or

[tex]A=2\pi \times r\times h[/tex]

We also know that, surface area = perimeter×height

So, the surface area of the cylinder is the product of circumference of the circle and height of the cylinder.

Answer:Solution for -5(p+3/5)=-4 equation:

-5(p+3/5)=-4

We move all terms to the left:

-5(p+3/5)-(-4)=0

We add all the numbers together, and all the variables

-5(+p+3/5)-(-4)=0

We add all the numbers together, and all the variables

-5(+p+3/5)+4=0

We multiply parentheses

-5p+4-3/5*5=0

We multiply all the terms by the denominator

-5p*5*5-3+4*5*5=0

We add all the numbers together, and all the variables

-5p*5*5+97=0

Wy multiply elements

-125p*5+97=0

Wy multiply elements

-625p+97=0

Her test score would be an 85 because 5x3=15 and then you would subtract 15 from 100 which would be 85

equation would be x=100-(5y)

Answer:

[tex]85[/tex]

Step-by-step explanation:

Let [tex]x[/tex] equal the number of questions.

Let's find how many total questions there are:

[tex]100=5x[/tex]

Divide by the coefficient of [tex]x[/tex], which in this case is [tex]5.[/tex]

[tex]20=x[/tex]

So we have a total of [tex]20[/tex] questions, each are worth [tex]5[/tex] points.

Now, Gianna got [tex]3[/tex] questions wrong, and if we know there are [tex]20[/tex] total questions...

[tex]20-3[/tex]

Solve.

[tex]20-3=17[/tex]

So we know Gianna got [tex]17[/tex] questions correct.

Let's use an expression to figure out her score.

Again, let [tex]x[/tex] equal the number of questions.

[tex]5x[/tex]

Substitute.

[tex]5(17)[/tex]

Multiply.

Answer:

Claire = 30 stickers

Josh = 60 stickers

Ann = 67 stickers

Step-by-step explanation:

Let

Claire stickers= x

Josh = 2x

Ann= 2x + 7

Total stickers = 157

Total stickers = Claire stickers + Josh stickers + Ann stickers

157 = x + (2x) + (2x+7)

157 = x + 2x + 2x + 7

157 = 5x + 7

Subtract 7 from both sides

157 - 7 = 5x + 7 - 7

150 = 5x

Divide both sides by 5

150/5 = x

30 = x

x = 30

Claire stickers= x

=30 stickers

Josh = 2x

= 2(30)

= 60 stickers

Ann= 2x + 7

= 2(30) + 7

= 60 + 7

= 67 stickers

Claire = 30 stickers

Josh = 60 stickers

Ann = 67 stickers
