1. The number of sides of the polygon is 8

2. The value of x is 36

A polygon can be defined as a flat or plane. The sum of a regular polygon is expressed as (n-2)180. The sum of exterior angle of a polygon is 360.

Therefore the sum of the interior is 5 times the exterior.

(n-2)180 = 5×360

180n - 360 = 1800

180n = 1800-360

180n = 1440

divide both sides by 180

n = 1440/180

n = 8

therefore the number of sides of the polygon is 8

2. The number of sides of the polygon is 6

Therefore the sum of angle in the polygon = 6-2)180 = 4× 180

= 720°

x+3x+6x+4x+4x+2x = 720

20x = 720

x = 720/20

x = 36

therefore the value of x is 36

The line of reflection is y = -1, which is the equation of the horizontal line passing through the midpoint of the line segment joining E and E'.

Two different points on a line define the boundaries of a line segment in geometry. Or, a line segment is a section of the line that links two points, as another alternative. In contrast to a line, which has no endpoints and can go on forever, a line segment has two distinct endpoints that are set or identifiable.

From the given image, we can see that the original polygon ABCDE has point E at (-3, 1), and the reflected polygon A'B'C'D'E' has point E' at (-3, -3). This means that the reflection must have occurred across the horizontal line passing through the point (-3, -1), which is the midpoint of the line segment joining E and E'.

Therefore, the line of reflection is y = -1, which is the equation of the horizontal line passing through the midpoint of the line segment joining E and E'.

The quadrilateral is most specifically a parallelogram because the opposite sides are parallel to each other

A parallelogram is a geometric shape with four sides, where opposite sides are parallel and congruent (having the same length), and opposite angles are also congruent (having the same measure).

In other words, a parallelogram is a quadrilateral (a polygon with four sides) where both pairs of opposite sides are parallel.

The opposite sides of a parallelogram are equal in length, and its diagonals bisect each other. The area of a parallelogram is equal to the product of its base (one of its sides) and its height (the perpendicular distance between the base and the opposite side).

Step-by-step explanation:

Answer:

Step-by-step explanation:

The equation you provided, y = 2/5 + 2, appears to be missing the variable x. Assuming you meant y = 2/5x + 2, here's how you can find the x-intercept:

To find the x-intercept, we need to find the value of x when y = 0. This is because the x-intercept is the point on the graph where the line crosses the x-axis, and at that point, the y-coordinate is always 0.

So, we can set y = 0 in the equation:

0 = 2/5x + 2

Subtracting 2 from both sides:

-2 = 2/5x

Multiplying both sides by 5/2:

-5/2 = x

Therefore, the x-intercept is at the point (-5/2, 0).

Answer:

Therefore, the break-even point for the entire company is approximately 0.784 or 78.4%.

Step-by-step explanation:

To calculate the break-even point, we need to find the total contribution margin, which is the difference between the total sales revenue and total variable expenses.

For Product R38T, the contribution margin is $33,000 - $8,840 = $24,160.

For Product X08S, the contribution margin is $54,000 - $32,050 = $21,950.

The total contribution margin for both products is $24,160 + $21,950 = $46,110.

To calculate the break-even point, we divide the total fixed expenses by the total contribution margin:

Break-even point = Total fixed expenses / Total contribution margin

= $36,130 / $46,110

= 0.784

Therefore, the break-even point for the entire company is approximately 0.784 or 78.4%.

The perimeter of the triangle JKL, obtained using the two tangent theorem, is 138 units

The two tangent theorem states the segments from the circle to the point at which two tangents to the circle meet are congruent.

The two tangent with common external point theorem indicates that the relationships between the lengths of the segments are;

5·x - 8 = 8·x - 35

8·x - 35 = 5·x - 8

8·x - 5·x = 35 - 8 = 27

3·x = 27

x = 27/3 = 9

7·y - 9 = 2·y + 11

7·y - 2·y = 11 + 9 = 20

5·y = 20

y = 20/5 = 4

LO = 32 - (2·y + 11)

Therefore; LO = 32 - (2 × 4 + 11) = 13

The two tangents theorem, indicates that we get;

The perimeter, P, of the triangle JKL is therefore;

P = (5·x - 8) + (8·x - 35) + (7·y - 9) + (2·y + 11) + LM + LO

P = (5×9 - 8) + (8×9 - 35) + (7×4 - 9) + (2×4 + 11) + 13 + 13 = 138

Yes triangles are similar.

SAS theorem is used to prove triangles are similar.

The SAS similarity theorem states that if any two sides of the first triangle are exactly proportional to any two sides of the second triangle and the angle created by these two individual triangles is identical, then the two triangles must be similar. When we only know the length of two sides and the angle produced between those two sides in each triangle, this rule is often implemented.

ΔRST and ΔHJK triangles are similar.

According to the SAS theory,

∠ S=∠J (angles are equal)

SR/HJ=ST/JK

6/10=4.8/8.6=.6( both sides are proportional)

Triangles ΔRST and ΔHJK are hence identical.

Answer:

Area of shaded region= 1142.96mm²

Step-by-step explanation:

•First calculate the Area covered by the interior circle.

•To calculate the Area of the exterior circle first add the two radii to get the radius from the centre of the interior circle to the circumference of the exterior circle.

•Use the calculated radius to calculate the Area covered from the centre to the circumference of the exterior circle.

•Now subtract the Area of the interior circle from the area covered by the bigger circle to get the Area of the shaded region.

Answer:

1141.76

Step-by-step explanation:

To solve for the area of the entire circle, we must first solve for the radius. Adding 6 and 14 will get us the total radius of the circle.

Therefore, the radius of the entire circle is 20.

The expression you can use to solve for the area of a circle is:

Inserting the radius into the expression:

Therefore, the area of the entire circle is 400π.

If there is a hole in the circle in the shape of a circle, we must subtract the area of that hole to find the area of the shaded region.

Inserting 6 into the expression to solve for area:

Therefore, the area of the hole is 36π.

Now, we need to subtract the area of the gap from the area of the entire circle.

Because π is approximately equal to 3.14, we can calculate an approximate value for 364π by multiplying 364 by 3.14. This gives us:

Therefore, the area of the shaded region is [tex]1141.76^{2}[/tex]

The radius of the circle is r = 3.75

The radius of a circle is the distance from its center to its circumference.

To find the radius of the circle, we see that there is a right-angle triangle there. So, using Pythagoras' theorem, we have that

AC² = AB² + BC²

(6 + r)² = 9² + r²

Expanding the brackets, we have that

36 + 12r + r² = 81 + r²

Cancelling out r², we have that

36 + 12r = 81

Subtracting 36 from both sides, we have that

12r = 81 - 36

12r = 45

r = 45/12

r = 15/4

r = 3.75

1.Jake became anemic after the first blood transfusion because his body reacted to the foreign antigens.

2.He went into an anaphylactic shock after the second transfusion due to an even stronger allergic reaction.

1. After the first blood transfusion, Jake became anemic because he was given type O blood, which is not compatible with his own blood type. Incompatible blood transfusions occur when a person is given blood that carries a different antigen than the one they have. In this case, Jake was given type O blood, which carries both the A and B antigens, while Jake’s own blood carries the Rh antigen. Therefore, Jake’s body reacted to the foreign antigens and created antibodies to fight against them. This reaction caused Jake to become equation anemic, as his body was not able to absorb the oxygen from the transfused blood.

2. After the second blood transfusion, Jake went into an anaphylactic shock because he was given type O blood, which carries both the A and B antigens, while Jake’s own blood carries the Rh antigen. Since Jake’s body had already created antibodies to fight against the foreign antigens, when it was exposed to the same foreign antigens a second time, his body reacted with an even stronger immune response. This reaction caused Jake to go into an anaphylactic shock. In other words, the second transfusion caused an allergic reaction in Jake’s body, which was much more severe than the allergic reaction caused by the first transfusion.

Answer:

the missing 10% of 144 is 16. The whole amount would be 144 + 16 = 160.

Step-by-step explanation:

To find the missing 10%, you can use the fact that 100% is equal to the whole amount, and set up a proportion:

90/100 = 144/x

Simplifying this proportion, you can cross-multiply:

90x = 100 * 144

Then, you can solve for x:

x = (100 * 144) / 90

x = 160

Therefore, the missing 10% of 144 is 16. The whole amount would be 144 + 16 = 160.

The formula to calculate the future value of a present value deposit with compounding interest is:

FV = PV × (1 + r/n)^(n*t)

Where:

PV = Present Value (the initial deposit)

r = Annual interest rate (as a decimal)

n = Number of compounding periods per year

t = Number of years

Using this formula, we can calculate the future value of the $6000 deposit after 15 years:

PV = $6000

r = 6% = 0.06

n = 4 (compounded quarterly, i.e. 4 times per year)

t = 15 years

FV = $6000 × (1 + 0.06/4)^(4*15)

FV = $6000 × 1.458^60

FV = $6000 × 6.2565

FV = $37,539.00

Therefore, the future value of the $6000 deposit after 15 years with quarterly compounding at 6% interest rate is $37,539.00.
