The complete table when Noah is running a marathon at a constant speed of 6 miles per hour is mentioned below:

Time                 Distance

 1                           6

 1/2                        3

 [tex]1\frac{1}{3}[/tex]                         8

  9                        54

 [tex]4\frac{1}{2}[/tex]                        27

The running speed of Noah is 6 mph.

The formula for distance is given as:

D = v × t

Where D is the distance, v is the speed and t is the time.

Now,

When t = 1 hour,

D = 6 × 1 = 6 miles

When t = 1/2hour,

D = 6 × 1/2 = 3 miles

When t = [tex]1\frac{1}{3}[/tex] hour,

D = 6 × [tex]1\frac{1}{3}[/tex] = 6 × 4/3 = 8 miles

When t = [tex]1\frac{1}{2}[/tex] hour,

D = 6 × [tex]1\frac{1}{2}[/tex] = 6 × 3/2 = 9 miles

When t = 9 hours,

D = 6 × 9 = 54 miles

When t = [tex]4\frac{1}{2}[/tex] hour,

D = 6 × [tex]4\frac{1}{2}[/tex] = 6 × 9/2 = 27 miles

Therefore, the table will be:

First option is correct. A t - shirt cost $7.50 and a pair of shorts cost $23

First, it's crucial to understand linear equations.

Equation connects the two algebraic expressions with an equal to sign to demonstrate the equality between them.

Linear equations are those with one degree.

Simultaneous linear equations are two or more linear equations that can be solved simultaneously to find a common solution.

Let the price of one t-shirt be $x and price of one pair of shorts be $y

A t-shirt and two pairs of shorts cost $53.50

So, x + 2y = 53.50 .................... (1)

Two t-shirts and three pairs of shorts cost $84.

So, 2x + 3y = 84 ................ (2)

Multiplying (1) by 2,

2x + 4y = 107 .............(3)

Subtracting (2) from (3),

4y - 3y = 107 - 84

y = 23

Putting the value of y in (1)

x + 2[tex]\times[/tex]23 = 53.50

x = 53.50 - 46

x = 7.50

A t shirt cost $7.50 and a pair of shorts cost $23

A major weakness of the Articles of Confederation is that: B. States could ignore laws passed by the Congress.

The Articles of Confederation can be defined as the first written documents that were regarded as the Constitution of the United States of America, which was agreed upon by the thirteen (13) original states.

Under the Articles of Confederation, the national government was unable to raise revenue due to lack of enforcement powers of the confederate Congress.

In conclusion, we can reasonably infer and logically deduce that one of the limitations of the Articles of Confederation was the inability of Congress to enforce the laws it made because they can be ignored by states.

In elementary algebra, the binomial expansion defines the algebraic expansion of powers of a binomial. The binomial equation be 27x² - 300 exists 3(3x + 10)(3x - 10).

In elementary algebra, the binomial theorem (or binomial expansion) defines the algebraic expansion of powers of a binomial. According to the theorem, it exists possible to extend the polynomial  [tex]$(x+y)^n$[/tex] into a sum involving terms of the form [tex]$a x^b y^c$[/tex], where the exponents b and c exists nonnegative integers with b + c = n, and the coefficient a of each term exists a specific positive integer depending on n and b.

Let the binomial equation be 27x² - 300

Factor out common term 3:

[tex]$\quad 3\left(9 x^2-100\right)$[/tex] [tex]$=3\left(9 x^2-100\right)$[/tex]

simplifying the above equation, we get

Factor [tex]$9 x^2-100: (3 x+10)(3 x-10)$[/tex]

= 3(3x + 10)(3x - 10)

If 3(3x - b)(3x + b) then we get

= 3(3x + 10)(3x - 10)

b = 10

The value of b = 10.

Therefore, the correct answer is option a. 10.

Answer: x=3

Step-by-step explanation:

6x-15-4x+8=-1

2x-7=-1

2x=6

x=3

Answer:

-6

Step-by-step explanation:

by using -6 any value of x would make the equation true resulting in infinitly many solutions

We're given : x+y+z = 4
x = -2y
z = -3y

So, we replace x = -2y and z = -3y in the original equation.

-> -2y + y + -3y = 4
-> -4y = 4
-> y = -1

Now we have the value of y, we substitute it into x and z
x = -2y = -2(-1) = 2
z = -3(-1) = 3

The vertices of the image are the points J'(x, y) = (3, - 1), K'(x, y) = (4, - 5) and L'(x, y) = (0, - 3), respectively.

Triangles are created by three non-colinear points called vertices and the location of the image of the triangle is found by using a reflection around a line parallel to the x-axis for every point of the figure. This operation is described by the following expression:

P'(x, y) = P(x, y) - 2 · [P(x, y) - (p, k)]

Where:

If we know that J(x, y) = (3, - 5), K(x, y) = (4, - 1), L(x, y) = (0, - 3) and k = - 3, then the coordinates of the vertices of the image of the triangle are:

J'(x, y) = (3, - 5) - 2 · [(3, - 5) - (3, - 3)]

J'(x, y) = (3, - 5) - 2 · (0, - 2)

J'(x, y) = (3, - 5) + (0, 4)

J'(x, y) = (3, - 1)

K'(x, y) = (4, - 1) - 2 · [(4, - 1) - (4, - 3)]

K'(x, y) = (4, - 1) - 2 · (0, 2)

K'(x, y) = (4, - 1) + (0, - 4)

K'(x, y) = (4, - 5)

L'(x, y) = (0, - 3) - 2 · [(0, - 3) - (0, - 3)]

L'(x, y) = (0, - 3) - 2 · (0, 0)

L'(x, y) = (0, - 3) + (0, 0)

L'(x, y) = (0, - 3)

The vertices of the image of the triangle are J'(x, y) = (3, - 1), K'(x, y) = (4, - 5) and L'(x, y) = (0, - 3).

First step

We want to find the cost of each shirt Blair paid. In order to find it we want to find the total price Blair paid for the whole order and then divide it by 150 (total number of shirts).

She chose Company B.

They charge $3.10 per shirt, plus 4% of the total order for shipping.

There are 150 shirts, then the total order for shipping is:

150 · $3.10 = $465

we want to add the 4%. The 4% of $465 is

$465 · 4/100 = $465 · 0.04

= $18.60

If we add it to the total order for shipping:

$465 + $18.60 = $483.60

Second step

Now we divide the total price of 150 into 150: this is the cost for one shirt.

$483.60/150 = $3.224

If we round it to the nearest hundredth:

$3.224 ≅ $3.22

Answer- The total cost Blair paid for one T-shirt is $3.22

We know that she needs to add 75% to the total cost.

Let's remember that every percentage is equivalent to it divided by 100: for example 100% is equivalent to 1. For 75%:

75% = 75/100 = 0.75

Then 75% is equivalent to 0.75.

This means that if we want to find the 75% of something we multiply it by its equivalent: 0.75.

Answer- She can calculate the markup by multiplying her total cost by 0.75

Based on the previous parts, we know that we want to add the 75% (0.75) of the cost of each T-shirt Blair paid ($3.22).

We first find the 75% of $3.22 and then add it to it: it will be the cost of sell.

First step

The 75% of the total cost of each shirt ($3.22) is:

0.75 · $3.224 = $2.418

Second step

Adding the 75% to the total price:

$3.224 + $2.418 = $5.642

If we round it to the nearest hundredth:

$5.642 ≅ $5.64

Answer- Blair will sell each T-shirt at the carnival for $5.64.

After calculating basic arithmetic we have come to find that, 1523 boxes of crayons are produced in each hour if crayons manufactory produces 36,552 crayons in an hour.

Arithmetic ((arithmós) 'number', 'art, craft') is a fundamental branch of mathematics that focuses on the properties of traditional operations on numbers such as addition, subtraction, multiplication, division, exponentiation, and root extraction.

Giuseppe Peano, an Italian mathematician, formalized arithmetic in the nineteenth century with his Peano axioms,[disputed - discuss], which are still very important in the field of mathematical logic today.

The prehistory of arithmetic is limited to a few artifacts that may indicate the concept of addition and subtraction, the best-known of which is the Ishango bone from central Africa, which dates from somewhere between 20,000 and 18,000 BC, though its interpretation is disputed.

We have given that

crayon manufactory produces 36,552 per hours

Each box contain 24 crayons

No. of boxes manufactured in 1 hour = 36,552/24

                                                              = 1523

Thus, 1523 boxes of crayons are produced in each hour if Crayons manufactory produces 36,552 crayons in an hour.
