Step-by-step explanation:

Think of of this as a function in which the number of pounds is a function of the number of hours. Each piece of given information is a point. Each point has the format (x, y) = (hours, pounds), where hours is x and is the independent variable, and pounds is y and is the dependent variable.

You have two points (4.5, 1445) and (7, 2320). First find the slope of the line that passes through those two points. Use the slope formula,

m = (y2 - y1)/(x2 - x1).

Then using the slope and the point-slope equation of a line, find the equation of the line. The point-slope equation of a line is

y - y1 = m(x - x1),

where m = slope, and the point is (x1, y1).

Answer:

Percentage decrease ( from $4.09 to $3.59) is 0.1% ( Rounded to nearest tenth)

Percentage increase (from $3.59 to 4.09) is 0.1% ( Rounded to nearest tenth)

Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.

Step-by-step explanation:

$4.09 has been changed to $3.59.

Percent change = [(Value after  - Value before) / Value before]*100

                          =[tex]\frac{3.59-4.09}{4.09}*100[/tex]%

                          =[tex]\frac{-0.5}{4.09}*100[/tex]%

                          =[tex]-0.122249[/tex]%

                           =[tex]-0.1[/tex]% ( Rounded to nearest tenth)

Percentage decrease is 0.1% ( Rounded to nearest tenth)

Now lets calculate the percentage change from $3.59 to $4.09.

Percent change = [(Value after  - Value before) / Value before]*100

                          =[tex]\frac{4.09-3.59}{3.59}*100[/tex]%

                          =[tex]\frac{0.5}{3.59}*100[/tex]%

                          =[tex]0.13927[/tex]%

                           =[tex]0.1[/tex]% ( Rounded to nearest tenth)

Percentage increase is 0.1% ( Rounded to nearest tenth)

Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.

This mathematical problem involves calculating percentages of increase and decrease, using the same technique to calculate both. The percentage decrease when the price was marked down from $4.09 to $3.59 is approximately 12.2%, while the percentage increase from $3.59 back to $4.09 is approximately 13.9%, making the percentages of change different for the two price shifts. The greatest change occurs with the increase back to the original price.

The subject of this question is mathematics, specifically the calculation of percentage increases and decreases. To find the percentage decrease when the price was marked down from $4.09 to $3.59, we use the formula:

[(Old Price - New Price) / Old Price] x 100

[(4.09 - 3.59) / 4.09] x 100 ~ 12.2%

So the percentage decrease is around 12.2%. Now, to calculate the percentage increase from $3.59 back to $4.09, we use the same approach:

[(4.09 - 3.59) / 3.59] x 100 ~ 13.9%

This gives us a percentage increase of approximately 13.9%. Therefore, the percentage of change is not the same for both price changes. The greater change is seen with the increase back to the original price, which results in a larger percentage of 13.9% compared to the decrease of 12.2%.

The correct product of 27 and 600 is:

[tex]\[ \boxed{16200} \][/tex]

"The correct answer to find the product of 27 and 600 is not obtained by simply adding 27 six times and then appending zeros. The correct method to calculate 27 x 600 is as follows:

 First, multiply 27 by 6 to get the hundreds place value correct:

[tex]\[ 27 \times 6 = 162 \][/tex]

Next, since we are multiplying by 600, we need to account for the additional zeros. Each zero represents a factor of 10, so we multiply 162 by 100 (since there are two zeros in 600):

[tex]\[ 162 \times 100 = 16200 \][/tex]

Therefore, the correct product of 27 and 600 is:

[tex]\[ \boxed{16200} \][/tex]

The method described in the question is incorrect because it does not properly account for the place value of the digits in the multiplication. When multiplying by a number with zeros, each zero represents a power of ten and must be considered in the multiplication process. The correct method involves multiplying the numbers and then adjusting the final product's place value by adding zeros according to the multiplier's zeros."

Answer:

$639.98 is budgeted for the rent.

Step-by-step explanation:

Joshua's monthly salary is $2,909 and the budget for the rent is 22% of her salary.

For finding the amount of rent, we just need to find 22% of $2909. For that, first we need to convert 22% into decimal by dividing it by 100 and then multiply this result with $2909.

So, [tex]22\%= \frac{22}{100}=0.22[/tex]

Now,  [tex](\$2909*0.22)= \$639.98[/tex]

Thus, $639.98 is budgeted for the rent.

The slope of the Line is 3

What is the slope of a line?

Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) may be easily determined by finding the difference among the coordinates of the points. The slope is normally represented by the letter 'm'.

Conclusion: The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.

The general equation of a line having a slope is y = mx + c

we have to arrange the equation 6x - 2y = 10 in y = mx + c form

6x -2y = 10

2y = 6x - 10

Answer:

In order to increase humidity by 49.17 grams per kilogram, the increase in temperature will be 18 degree Celsius approx.

Step-by-step explanation:

Initial humidity = 5.75 g/kg

Final humidity= 49.17 g/kg

Percentage increase in humidity= (49.17-5.75)/5.75 *100= 755.13

Increase in temperature= 755.13/43 = 17.56

Increase in temperature = 18 degree Celsius approx.

Answer:

The temperature must increase by more than 6 degree Celsius for the humidity to reach at least 49.17 grams per kilogram

Step-by-step explanation:

Given : Humidity on Monday morning = 5.75 grams per kilogram

To Find: He wants to know how much the temperature must increase for the humidity to reach at least 49.17 grams per kilogram.

Solution :

Let T be the increase in temperature, in degrees celsius, from monday morning.

According to question

The humidity measured in grams of water per kilogram of air, increases by 43% for every 1 degree Celsius increase in temperature.

So. Rate of increment is 43%

So, it becomes : [tex]100+43=143\% =1.43[/tex]

43% increases for every 1 degree celsius.

So, for T the increase is 1.43*T

So, [tex]1.43T\geq \frac{49.17}{5.75}[/tex]

[tex]1.43T\geq 8.55[/tex]

[tex]T\geq \frac{8.55}{1.43}[/tex]

[tex]T\geq 5.97[/tex]

Thus the temperature must increase by more than 6 degree Celsius for the humidity to reach at least 49.17 grams per kilogram

Answer:

Side of Squared shaped plot = x foot

Then the farmer fences off a 25 foot wide section to create an area to store equipment.

As width=25 foot

and Length =x foot

Area = 25 x square foot

So 25 x represents area which is used for storing equipment.

So out of all the options Option D is correct which is The area of the land fenced off to store equipment .

Answer

The statement best describes the term 25x is  option ( D)

i.e  The area of the land fenced off to store equipment.

Reason

As given in the question

A farmer has a square-shaped plot of unused land

After the farmer fences off

he fences off a 25-foot wide section to create an area to store equipment.

x represent the original length of the plot.

this shows that the plot used to store equipment is not square.

Formula

Area of the rectangle = length × breadth

length = x

breadth = 25

put in the above equation

Area = 25x feet²

therefore 25x feet² shows the area of the land fenced off to store the equipment.

Answer: She will need 142 ft of curtain.

Step-by-step explanation:

Hi, first we have to convert the length of the curtain from inches to foot.

Since 1 inch = 1/12ft  

For 24 inches:

24 inches x 1/12 = 2 ft

Since the company wants to make 71 curtains, we have to multiply the length of each curtain (2ft) by 71.

2ft x 71 = 142ft

She will need 142 ft of curtain.

To find segment AD given HD = 24 when H is the centroid, you would use the property of the centroid that divides medians in a 2:1 ratio. Since HD is the shorter part, multiply 24 by 2 to get AD = 48 units.

You're asking how to find the length of segment AD given HD = 24 in a geometric context involving a centroid. To find AD, we must understand the properties of the centroid, which is the point where the three medians of a triangle intersect. A median connects a vertex of a triangle to the midpoint of the opposite side, and in every triangle, the centroid divides each median in a 2:1 ratio, with the longer segment being closest to the vertex.

Given that HD = 24 and D is the midpoint of AH (because H is the centroid), according to the centroid properties, the length of AD must be twice the length of HD. Therefore:

AD = 2 * HD

AD = 2 * 24

AD = 48

The length of segment AD is 48 units.
