The number of the sides of the polygon will be 15. Then the correct option is A.

The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.

Each exterior angle of a regular polygon measures 24°.

Then the number of the sides of the polygon will be

Let n be the number of the sides. Then we have

360° / n = 24°

          n = 360° / 24°

          n = 15

Then the number of the sides of the polygon will be 15.

Then the correct option is A.

A rectangle is the shape with parallel opposite sides, combined with all the 90 degree angles. As the type of the parallelogram, it has the opposite parallel sides. In the rectangle, 1 set of parallel sides is longer than the other, making it look like an elongated square

The rectangle field is 400 meters long and 300 meters wide. What is the area in square kilometers?

1km=1000m

Secondly the area of the rectangle is defined as the product of the width or the height:

A= w∗h

We could now approach the problem in 2 ways, we convert the sides of the rectangle to kilometers 1st and we convert the area from square meters to the square kilometers.

Let w = width, h = height and A = area

w=300m=300/1000m=0.3km

h=400m=400/1000m=0.4km

A=0.3∗0.4km2=0.12km2

Let's first calculate the area in square meters:

Am=300∗400=120000m2

We know from above that 1km=1000m

That gives 1km2=1000∗1000m2=1000000m2

So Ak=Am/1000000=0.12km2

the area of the rectangular field is 0.12 square kilometers.

To calculate the area of a rectangular field in square kilometers, you need to multiply the length and width of the field and then convert the result from square meters to square kilometers. Given that the rectangular field is 400 meters long and 300 meters wide, the area in square meters is calculated as follows:

Area = length × width = 400 m × 300 m = 120,000 m2

Since 1 square kilometer (km2) is equal to 1,000,000 square meters (m2), you convert square meters to square kilometers by dividing by 1,000,000:

Area in square kilometers = Area in square meters / 1,000,000 = 120,000 m2 / 1,000,000 = 0.12 km2

Therefore, the area of the rectangular field is 0.12 square kilometers.

The histogram would change due to the different distribution of ages when all 20 students join the same event.

A histogram is a graphical representation of the distribution of numerical data. It consists of bars, where the length or height of each bar corresponds to the frequency or relative frequency of data within a specific interval or range. Histograms provide insights into data patterns and distributions.

The histogram would change when all 20 students join the same event compared to the original because the distribution of ages would be different. The original histogram would show the number of students participating in each event, while the new histogram would show the number of students in each age group. The new histogram would have different bars representing each age group, and the heights of these bars would be determined by the number of students in each age group.

Answer: x=4y+9

Step-by-step explanation:

All of the variables, 3x, 12y, and 27 can be divided y 3, so we will simplify by dividing the whole equation by 3.

3x/3-12y/3=27/3

Which is equal to....

x-4y=9

Now you can move -4y over to the right side by changing its sign...

x=4y+9

Let the equation be 3x - 12y = 27 then, the value of x = 9 + 4y.

Given: 3x - 12y = 27

To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

Solve the value of x, then

Add 12y to both sides

3x - 12y + 12y = 27 + 12 y

Simplifying the above equation, we get

3x = 27 + 12y

Divide both sides by 3, then we get

[tex]$\frac{3 x}{3}=\frac{27}{3}+\frac{12 y}{3}$$[/tex]

Therefore, the value of x = 9 + 4y.

Answer:

360 and 60.

Step-by-step explanation:

Let Christopher earns x amount of money and y be money earned by Michael.

Firstly, Christopher has six times as much money as Michael so,

x=6y........ (i)

If Michael earns $80 and Christopher earns $60, Christopher will then have three times as much money as Michael so,

x+60=3(y+80)

From (i),

6y +60= 3(y+80)

3(2y+20)=3(y+80)

2y+20=y+80

2y-y=80-20

y=60

Substituting value of y in equation (i),

x=6×60=360.

Therefore, Christopher earned 360 and Michael earned 60.

Final answer:

Initially, Michael has $60, and Christopher has $360. After Michael earns $80 and Christopher earns $60, Michael will have $140, and Christopher will have $420.

Explanation:

Let's denote Christopher's initial amount of money as C and Michael's initial amount of money as M.

According to the given information, Christopher has six times as much money as Michael: C = 6M.

When Michael earns $80, and Christopher earns $60, Christopher will then have three times as much money as Michael: C + $60 = 3(M + $80).

Now we can solve these two equations together:

C = 6M

C + $60 = 3(M + $80)

Substitute the expression from the first equation into the second equation:

6M + $60 = 3(M + $80)

6M + $60 = 3M + $240

Combine like terms:

6M - 3M = $240 - $60

3M = $180

Divide both sides by 3:

M = $60

Use the value of M to find C:

C = 6M = 6 × $60

C = $360

Now, adding their respective earnings:

Michael's new total: $60 + $80 = $140

Christopher's new total: $360 + $60 = $420

Answer:

X=12

Step-by-step explanation:

Move constant to the right side and change its sign

-27x-x+240=-96

collect the like terms

calculate the difference

-28x=-336

Divide both sides of the equation by -28

Step-by-step explanation:

KLMN is in the same spot as PQRS

Answer:

QR corresponds to LM

Step-by-step explanation:

Two figures are said to be similar if they have same shape but not necessarily same size.

Two polygons are said to be similar if their corresponding angles are equal and corresponding sides are proportional .

A trapezoid is a polygon in which a pair of sides is parallel .

Here, two trapezoids are given i.e KLMN, PQRS.

As KLMN and PQRS are similar, so their angles are equal i.e

[tex]\angle K=\angle P\,,\,\angle L=\angle Q\,,\,\angle M=\angle R\,,\,\angle N=\angle S[/tex]

Also, corresponding sides are proportional i.e

[tex]\frac{KL}{PQ}=\frac{LM}{QR}=\frac{MN}{RS}=\frac{KN}{PS}[/tex]

Therefore, side QR corresponds to LM.

Answer:

17.41

Step-by-step explanation:

497.50 x 0.035

Jodi's investment will earn $17.41 in interest in one year at an interest rate of 3.5%. Therefore, after one year, her investment will be worth $514.91.

To find out how much Jodi's investment is worth in one year, we can use the formula for simple interest, which is Interest = Principal x Rate x Time. In this case, the principal is $497.50, the rate is 3.5% (or 0.035 in decimal form), and the time is 1 year.

So, the interest earned in one year would be $497.50 x 0.035 x 1 = $17.41.

To find the total worth of her investment after one year, we add the interest earned to the initial principal. So, $497.50 (the principal) + $17.41 (the interest) = $514.91. Therefore, her investment is worth $514.91 after one year.

Answer:

Step-by-step explanation:

To create a system of inequalities, write an inequality to model each condition that must be satisfied in the given situation.

It is given that x represents the area of the base of the barrel in square feet and y represents the volume of the pump in cubic feet.

Write an inequality to represent the amount of water that the barrel needs to hold after the pump is inserted. To find the volume of the barrel, multiply the area of the base by the height of the barrel. Then subtract the volume that will be taken up by the pump from that amount.

x(x-4) - y ≤ 90

To find the cost of the supplies for the barrel, find the surface area by multiplying the perimeter of the base by the height of the barrel and then adding the area of the base. Since there is no top, the area of the base only needs to be added once. Then, multiply the cost per square foot by the surface area.

To find the cost of the pump, multiply the cost per square foot of the pump by its volume.

Write an inequality representing the total cost. The cost must be less than or equal to $1,100.

8(x(x-4)+x) + 50y ≤ 1,100

Combining both of the inequalities gives the following system of inequalities.
