If a case of 24 pairs of the same kind of switches cost a little more than $800. $28 per pair with tax included is not  good estimate of the price  but  $33.33 is the good estimate for the price .

Assuming that the  cost per pair is the amount of $28. Hence, cost of 24 pairs is calculated as:

Cost= $28x24

Cost  = $672.

Based on the above calculation for the cost of 25 pairs we can see that that the  24 pairs of the same kind of switches does not cost more than $800 which implies that $28 is not good estimate for the price.

Now let determine the best estimate of the price with tax included :

Cost = $800/24

Cost = $33.33

Therefore the good estimate for the price with the tax included is $33.33.

The illness is spreading at a rate of 10% per hour -> it is spreading 1.1x faster per hour as 10% more people are infected each time.

Therefore, we can write the amount of people infected as 3 x [tex]1.1^{n}[/tex], where n is the hour. So, if n equals 1, the amount of people infected is 3 x 1.1 = 3.3 (so when this mark surpasses the 1200 limit, we round up to the nearest whole number)

It will take 1200 : 3 : 1.1 = 363.636364.. (hours)

If it's only 363 hours, the number of people infected will not have reached 1200, as we have .636364 hours left. So, it will take 364 hours.

Answer:

1. perpendicular

2. parallel

3. neither

Step-by-step explanation:

The first set of lines are perpendicular because they intersect each other at a right angle.

The second set of lines are parallel because they never cross.

The first pair forms a 90° angle therefore the lines are perpendicular.

The second lines are straight that it's obviously clear they will never meet meaning they are parallel

the third lines are neither perpendicular nor parallel.

Based on the number of bushels that the farmer has to sell, the equation that represents the total change in the number of bushels after seven days is 220 - 15⁵/₈(7).

The farmer has a total of 220 bushels of wheat to sell and then sells about 15⁵/₈ every day.

After 7 days, the total change in the number of bushels would be:

= Total bushels to be sold - Bushels of wheat already sold

= Total bushels to be sold - (Number of bushels sold per day x Number of days)
= 220 - 15⁵/₈(7)

The answer to the given word problem is as follows. From the calculations: Johanna purchased

A word problem is a few phrases that describe a real-life scenario in which an issue must be solved using a mathematical computation.

The calculations is given as follows:

Step 1 -  First, let's define the variables to represent the unknowns.

Let p = number of pens

Let n = number of notebooks

Let h = number of highlighters

p + n + h = 17 ......................... 1  (purchased 17 items)

.5p + 4n + 1.5h = 41.5 ...................2 (total cost $41.50)

n = h+3  ................................3 (3 more notebooks than highlighters)

Step 2...............Solve for P in equation 1

P = 17 - n - h..................4

Recall that in equation 3,

n = h + 2

If we make n the subject of the expression, we have:

n = h+ 3

Substituting that into equation 4, we have

p = 17 - (h+3) - h
p = 17 -2h - 3 ..................5

Going back to equation 2, let's substitute n with h+3 and replace p with 17 -2h - 3

.5(17 -2h - 3) + 4 (h+3) + 1.5h = 41.5

To remove all decimals, we can multiply all with 10 to get:

5(170-20h -30) + 40(10h +30) + 15h = 415

Expand all brackets and we have:

850 - 100h - 150 + 400h + 1200 + 15h = 415

Collect like terms

-100h + 400h + 15h = 415-850+150-1200

315h = -1485

h = -1485/315

h = -4.71

Since a physical item cannot be negative, we utilize the absolute value which is:

h = 4.71

h [tex]\approx[/tex] 5 highlighter

Recall that

n = h + 3

Hence

n = 5 +3 = 8 notebooks

Recall that

p + n + h = 17

Hence we have

p + 8 + 5 = 17

p = 17 -8 - 5

p = 17 - 13
P = 4 pens.

Hence Johanna purchased

4 pens, 8 notebooks and 5 highlighters.

4y = x + 6 is the equation of the line using the slope value.

The steepness of a line segment is explained by the slope of the line. It is a ratio of the vertical x-axis coordinates and the y-axis coordinates. The classification of whether two lines are parallel or perpendicular depends on the slope value.

The parameters for the line segment are as follows, in accordance with the question:

The coordinate points (6, 3) and the slope of a line (1/4) are as follows: (x = 6; y = 3)

Using the line segment's standard equation now: y = mx + c

If (x, y) are coordinates, "m" is the slope, "c" is the y-intercept,

The following results are obtained by replacing the slope and y-intercept values in the formula:

y = mx + c

⇒ 3 = (1/4)(6) + c

⇒ c = 3 - 3/2 = 3/2

Consequently, c = (3/2) is the y-value. intercept's

by changing the slope value and y-intercept value in the line's equation:

y = (1/4)x + (3/2) = 4y = x +6

x² + (2/3)x - 1/9 = 0

We have been given the roots of quadratic equation.

(-1 - √2)/3 and (-1 + √2)/3

We need to find the quadratic equation.

Since (-1 - √2)/3 and (-1 + √2)/3 are roots, (x - (-1 - √2)/3) and (x - (-1 + √2)/3) must be the factors of the quadratic equation.

So, the required quadratic equation would be,

(x - (-1 - √2)/3) * (x - (-1 + √2)/3) = 0

x[x - (-1 + √2)/3) ] - ( (-1 - √2)/3) [x - (-1 + √2)/3] = 0

x² - x(-1 + √2)/3 - x(-1 - √2)/3 + [(-1 - √2)(-1 + √2)]/9 = 0

x² - x(-2/3) + (1 - 2)/9 = 0

x² + (2/3)x - 1/9 = 0
