The shopper must buy six 4-packs sandwiches.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of sandwiches to buy = 24

Cost of six-pack sandwiches = $5.28

Cost of four-pack sandwiches = $3.40

Cost of 24 sandwiches from the six-pack.

= 4 x 5.28

= $21.12

Cost of 24 sandwiches from the four-pack.

= 6 x 3.40

= $20.4

Thus,

Six four-pack sandwiches are cheaper than four six-pack sandwiches.

The probability that this song will be played on exactly 0 days out of 7 days, if The probability that a particular song is played is 0.23 is 0.008.

A combination is a choice of items from a group of different items, where the order of the choices is irrelevant.

Given:

The probability that a particular song is played is 0.23,

As can be seen that the problem is of combination, so we have to choose 5 out of 7,

Calculate the combination as shown below,

⁷C₅ = 7! / (5! × 2!) = 7 × 6 / 2

⁷C₅ = 7 × 6 / 2

⁷C₅ = 21

Calculate the probability as shown below,

P = ⁷C₅  × (0.23)⁵ × (0.77)²

The number of calories for 180-gram burrito is 392

From the question, we have the following parameters that can be used in our computation:

The scatter plot

From the line of the best fit on the scatter plot, we have the following points

(0, 250) and (190, 400)

A linear function is modelled by:

y = mx + b

In which:

m is the slope, which is the rate of change

b is the y-intercept, which is the value of y when x = 0

Using the above points, we have

b = 250

This means that

y = mx + 250

From the point (190, 400), we have

400 = 190m + 250

So, we have

190m = 150

And, this gives

m = 15/19

So, the equation is

y = 15/19x + 250

For a 180-gram burrito, we have

y = 15/19 x 180 + 250

Evaluate

y = 392

Hence, the number of calories is 392

The first graph shows how many of each order could fit into a bag that was hanging from a hook. First, a detailed explanation: * Let's discuss the issue's solution.

The quantity of orders of paperclips is x, and the weight of the order of jumbo paperclips is 2 pounds. The order of paperclips weighs 2 x = 2 x, the order of packing tape weighs 3 lbs., and the quantity of orders of packing tape is y. The weight of the tape order is 3 y = 3 y, the weight of the entire order is 2 x + 3 y, and the hook can only support a maximum weight of 6 y. 2x + 3y ≤ 6

The graph that depicts this inequality, Any line's equation is y = mx + c, where m represents its slope.

The y-intercept indicates to replace x in the equation by 0; the x-intercept indicates to replace y in the equation by 0; 2x - 3y 6 is the inequality. 2x + 3y = 6 is the equation for the line.

- Subtract 2x from both sides: 3y = 6 - 2x; - Divide both sides by 3: y = 6/3 - 2/3 x; - Locate the y-intercept: x = 0; y = 2;

The line crosses the y-axis at position (0 , 2)

– Locate the x-intercept.

∵ y = 0

∴ 0 = 2 - 2/3 x

- Adjust both sides by 2/3x.

∴ 2/3 x = 2

Increase both sides by 3.

Divide all sides by 2 to get the answer.

The new coordinates of triangle KLM after the given translation is;

M'(6, 1)

L'(1, 4)

K'(4, 8)

In transformations, there are different types such as reflection, dilation, translation e.t.c

Now, translation is what we are dealing with here and translation is a rigid transformation which means that it does not alter the dimensions of the figure after transformation. Translation is just moving the object from one point to another.

In translation, the size, the shape and the orientation of the image remain the same as that of the original object. Thus, the same orientation means that the object and image are facing the same direction.

The given coordinates of the triangle are;

M(-2, 1)

L(-7, 4)

K(-4, 8)

Now, If you move horizontally 8 units to the right, it means that 8 is added to the x-coordinate of each of the vertices. Thus, the transformation rule here is;

(x, y) → (x + 8), y

Therefore the new coordinates of triangle KLM are;

M'(-2 + 8, 1) = M'(6, 1)

L'(-7 + 8, 4) = L'(1, 4)

K'(-4 + 8, 8) = K'(4, 8)

The equation of a parabola is y²+12x=0.

A parabola is a U-shaped plane curve in which any point is an equal distance from both a fixed point (known as the focus) and a fixed straight line (known as the directrix).

Parabola functions are classified into three types: standard form, vertex form, and intercept form (also known as factored).

as per the given question:

We have a vertex at (0,0) and the directrix is x = 3, a line parallel to the y-axis, it must have a focus at (3,0).

The parabola equation represents the locus of a point (x, y) that moves so that its distance from x=3 and (3,0) is equal. As a result, the parabola equation is, An equation of the parabola represents the locus of a point (x, y), which moves so that its distance from x=3 and (−3,0) are equal. Hence, the equation of a parabola is

(x−(−3))² + (y−0)² = (x−3)²

or (x+3)² + y² = (x−3)²

or x² + 6x + 9 + y² = x² − 6x + 9

or y² + 12x =0

Answer:

Here answer

Step-by-step explanation:

To find the number of hours Jayden would have to work to earn $105.00, we need to first find his hourly wage. We can do this by dividing his total earnings by the number of hours he worked:

hourly wage = total earnings / number of hours worked

= $87.50 / 5 hours

= $17.50/hour

Now that we know Jayden's hourly wage, we can use it to find the number of hours he would have to work to earn $105.00. We can do this by dividing the total amount he wants to earn by his hourly wage:

number of hours = total earnings / hourly wage

= $105.00 / $17.50/hour

= 6 hours

Therefore, Jayden would have to work for 6 hours to earn $105.00 at his job.

It is to be noted that the length of the interior diagonal of the box whose dimensions are Height 100cm, Lenght, 80 cm, and width 60 cm, is 140.4cm.

Recall that the formula for the diagonal length of a right rectangular prism is calculated as √(l² + w² + h²) units. So, the formula for the length of a right rectangular prism's diagonal is √(l²+w²+h²), where l is the length, b is the breadth, and h is the height.

Plugging in the values we have:

d² = 60² + 80² + 100²

Solving for d, we get:

d = √(660² + 80² + 100²)

= √(3600 + 6400 + 10000)
