Step-by-step explanation:

Answer:

B

Rational number

Answer:

[tex]n^2 + \frac{2n}{3} + \frac{1}{9} = \frac{1}{9}[/tex] -- Perfect square trinomial

[tex](n + \frac{1}{3})^2 = \frac{1}{9}[/tex] ---Binomial squared

Step-by-step explanation:

Given

[tex]n^2 + \frac{2n}{3}[/tex]

Solving (a): Perfect square trinomial

We have:

[tex]n^2 + \frac{2n}{3}[/tex]

Express as an equation

[tex]n^2 + \frac{2n}{3} =[/tex]

Start----------------------------

Take coefficient of n i.e. (2/3)

Half it: i.e. (1/3)

Square it: (1/63^2

Add to both sides of the equation

---------------------------End

So, we have:

[tex]n^2 + \frac{2n}{3} + (\frac{1}{3})^2 = (\frac{1}{3})^2[/tex]

Remove brackets

[tex]n^2 + \frac{2n}{3} + \frac{1}{9} = \frac{1}{9}[/tex]

Solving (b): Binomial Squared

[tex]n^2 + \frac{2n}{3} + \frac{1}{9} = \frac{1}{9}[/tex]

Expand

[tex]n^2 + \frac{n}{3}+ \frac{n}{3} + \frac{1}{9} = \frac{1}{9}[/tex]

Factorize:

[tex]n(n + \frac{1}{3})+ \frac{1}{3}(n + \frac{1}{3}) = \frac{1}{9}[/tex]

Factor out n + 1/3

[tex](n + \frac{1}{3})(n + \frac{1}{3}) = \frac{1}{9}[/tex]

Express as square

[tex](n + \frac{1}{3})^2 = \frac{1}{9}[/tex]

just chuck it in wolfram alpha

Answer:

first step is to minus 28.7 - 6.7=22 (I did the minus because I want to get the remaining length of the rope )

step 2 : is to divide 22 by 2 (because the question said they should divide it into two pieces )

then the answer you get from the division of 22/2 which is 11 that would be the final answer

meaning each tire swing is 11m

Sal will pay $77.78 to tile his entryway  

The image of the question is attached below.  

Given each unit length = 1 foot  

Tile cost per square feet = $1.  65

To find the area, split the floor shape into two shape.  

One is trapezoid and the other is parallelogram.  

Let's count the grid given.  

The parallels sides of trapezoid are 7 ft and 4 ft, height is 7 ft.  

The base and height of the parallelogram are 4 ft and 4 ft respectively.  

Area of the trapezoid =1/2 ×(sum or parallel  sides)× height

                                      =1/2× (7+4)×5

                                       =1/2×11×5

Area of the trapezoid = 27.5 sq.ft  

Area of the parallelogram = base × height  

                                       = 4 ft × 4 ft  

Area of the parallelogram = 16 sq. ft  

Total area = 27.5 sq. ft + 16 sq. ft  

              = 43.5 sq. ft  

Cost of area per sq. ft = $1.65  

Cost of area 43.5 sq. ft = 43. 5 × 1.65  

                                   = $71.775

                                   = $71.78  

Hence Sal will pay $71.78 to tile his entryway.

Answer:

  d. √74 units

Step-by-step explanation:

The distance formula is useful for finding the length of a line segment.

  d = √((x2 -x1)^2 +(y2 -y1)^2)

Filling in the point coordinates L(-5, -3) and M(0, 4), we find the length of LM to be ...

  LM = √((0-(-5))^2 +(4 -(-3))^2) = √(25 +49)

  LM = √74 . . . units

Answer:

B

Step-by-step explanation:

You don't even have to do complicated the math as the numbers are complicated for a reason. Round 1.99 to 2 and 1.83 to 1. and the answer is 5.4, which is closest to answer B.

Marissa buys 5 bottles of soda which cost X, she also buys a 9 dollar meal. If her total cost was 44 dollars, how much does each bottle cost?

Step-by-step explanation:

Answer:

there was was 5 fish in the tank and a shipment of x amount plus nine recent babies were born? equaling to 44 in total?

Step-by-step explanation:

Answer: x=14.4

Step-by-step explanation:2.5x=48-12

2.5x=36

x=14.4

Answer:

x = 14.4

Step-by-step explanation:

2.5x + 12 = 48

2.5x + 12 - 12 = 48 - 12

2.5x = 36

2.5x ÷ 2.5 = 36 ÷ 2.5

x = 14.4

Answer:

Angle RST is a straight angle, or 180°.

Step-by-step explanation:

Subsequently, question is, what is RST measured in? Triangle RST is isosceles means that two of its angles are equal. (1) The measure of angle T is 100 degrees --> since no other angle can be equal to 100 degrees (because in this case the sum of the angles will be more than 180 degrees) then the other two angles, R and S, are equal: R=(180-100)/2=40.

Likewise, people ask, what is the measure of angle rst 94?

Then the measure of arc RST is 94° +96° = 190°.

What is the measure of arc rst?

— RT is a diameter, so RST is a semicircle, and m RST = 180°. The measure of a minor arc is the measure of its central angle. The expression m AB is read as “the measure of arc AB.” The measure of the entire circle is 360°.

Its a positive slope since its going up.
