The number of times the bacterial cell is smaller than the amoeba cell is 1.6 * 10^-10

The given parameters are:

Bacteria cell = 4 x 10^-6 m

Amoeba cell = 2.5 x 10^4 m

The number of times (n) is calculated as

n = Amoeba cell/Bacteria cell

This gives

n = (4 x 10^-6 m)/(2.5 x 10^4 m)

This gives

n = 1.6 * 10^-10

Hence, the number of times the bacterial cell is smaller than the amoeba cell is 1.6 * 10^-10

A scaled copy of polygon with the scaled factor of 2 is Scale factor is defined as

It is a growing organism that falls between (0, infinity). According to the scale factor, an original figure might be either raised or decreased.

Consider two circles that appear to be the same. The word "identical" does not guarantee that both circles are of similar size. They could have various radii. One figure would be the other figure scaled down.

The ideas of ratio and proportion are intimately related to scale considerations. A given amount is multiplied or divided in ratio and proportions to create a new quantity.

A Scaled copy involves multiplying the lengths in the original figure by scale factor.

Here scale factor = 2,

Since the scale factor > 1, so there is an enlargement.

So, the scale copy's sides are 2 times of the sides of figure A.

The sales on which Joyce earns commission is the sale beyond $20,000 which is $2,650. So the total pay for a month for Joyce in which her sales is $22,650 is $1748.75.

Joyce is paid $1,550 per month plus a commission of 7.5% on all sales of more than a $20,000 monthly quota. For the given month her sales is $22,650.

Percentage means a number or a ratio represented in the form of fractions of 100. It is represented using the percentage sign ‘%’. The abbreviations used to represent the percentage are ‘pct’ or ‘pc’. In other words, the percentage is defined as how much of one quantity is made by another quantity and it is evaluated in terms of 100.

Total pay of Joyce = Her pay per month + Commission that she gets

Commission she gets is on the sales beyond $20,000.

Here, commission is on $22,650 - $20,000 = $2,650

She gets 7.5% commission. So, her commission is 7.5% * $2,650

=> 75/1000 * $2,650 = $198.75

So, the total pay of Joyce is $1,550 + $198.75

=> $1748.75 for the month.

1. A line segment can be written with just naming it by its end points and a bar above it while the name of a line requires an double-headed arrow mark above its name.

2. For constructing both a perpendicular and an angle bisector, we need to construct two arcs using a compass and their intersection point. A perpendicular bisector divided a line segment into two equal parts whereas an angle bisector divides an angle into two equal parts.

3. A perpendicular bisector can be drawn by drawing two arcs each above and below the line segment and joining using an straight edge.

1. A line and a line segment may sound quite similar however they are very different. A line, in short, is a line that never ends so it's infinite. It's the same for a line segment except at its end it is indicated by dots rather than arrows.

This difference can be seen in naming them too. A line segment is named using the initial and terminal points of the segment. Sometimes we put a 'bar' mark above its name. For example, [tex]\bar{AB}[/tex]

For a line of infinite length, it is named simply as 'line A' or 'line B' or sometimes put a double-headed arrow mark above its name.

2. A perpendicular bisector and an angle bisector are similar because they both require the need to find where two arcs meet. They are different because angle bisectors split into congruent angles meanwhile a perpendicular bisector splits into congruent segments.

Constructing a perpendicular bisector is similar in the sense that both are drawn using straight edge and compass and need to find the intersection point of the arcs. But they are different in their use as perpendicular bisector equally divides a line segment and an angle bisector equally divides an angle.

3. We have an unmarked straightedge and a compass. First put the compass at one end point A of the line. Then stretch the compass to a length more than half of the line segment AB to be bisected. In the next step, draw an arc above and one below the line. Next put the compass on the other end B of the line. Then repeat drawing two arcs, each above and below the line and also intersecting with the previous arcs. Finally join the two points got with a line cutting the line segment AB. This will be the perpendicular bisector of the line AB.

The value of 'x' in the given question is 27°.

Obtuse Angle may be defined as an angle that is greater than 90° and less than 180°. It may be also defined as an angle between a right angle and a straight-line angle.

From the question we can conclude that the given angles are vertically opposite to each other, and vertically opposite angles are always equal to each other.

Vertically opposite angles are formed when two lines are intersecting each other and the angles formed on each side of the intersection point are called vertically opposite angles.

Now according to the question:

[5(x-4)]°=(4x+7)°

Rearranging the terms:

(5x-20)°=(4x+7)°

=>x=27°

Therefore, the value of x is 27°.

Answer:9/28

Step-by-step explanation:

The coordinates of the point B are (-5, 6)

The given parameters are

A = (-8, 6)

Point = (2, 6)

Proportion = 2/3

Because the y coordinates are the same, we can make use of only the x coordinate

So, we have

Point = Proportion * (B - A)

This gives

2 = 2/3 * (B + 8)

Multiply through by 3/2

So, we have

3 = B + 8

Subtract 8 from both sides

B = -5

Answer:

$179.01

Step-by-step explanation:

(Second Step) $165.75 + 8% = $179.01

Step-by-step explanation:

(a)

the sum of all internal angles in a polygon with n sides is

(n - 2)×180.

since in a regular polygon all angles are equally large, we get for one internal angle :

(n - 2)×180/n

for our hexagon this means the internal angle is

(6 - 2)×180/6 = 4×30 = 120°

(b)

the area of the hexagon is (as the graphic so nicely suggests) the sum of the areas of all 6 inner triangles.

the area of a triangle is

baseline × height / 2

baseline = 10 cm

the height (from the tip of the triangle down to the baseline in a right angle) is half of 17.3 cm, because these 17.3 cm are the sum of the 2 heights of 2 triangles placed tip to tip.

so, height = 17.3/2 = 8.65 cm

the area of one of the triangles is therefore

10 × 8.65 / 2 = 5 × 8.65 = 43.25 cm²

the total area of the hexagon is then

6 × 43.25 = 259.5 cm²

Answer:

RS = 5

QS = 18

TS = 10

TV = 15

Step-by-step explanation:

Given QV = 23 and QT = 8 and TR = RS = SV

now, we subtract the length of QT from the whole line, QV

23 - 8 = 15 then we divide this by 3 because TR = RS = SV so there must be 3 equal pieces

15 ÷ 3 = 5

RS = 5

QS = QT + TR + RS so

QS = 8 + 5 + 5

QS = 18

TS = TR + RS so

TS = 5 + 5 and

TV = TR + RS + SV

TV = 15

6. The measure of each angle is  m∠ E = 46°, m∠ D = 46°.

Angle of elevation from point A to B (∠ E ) is the angle between the horizontal line from A to B.

And, Angle of depression from B to A ( ∠D ) is the angle from the horizontally downward line from B to A.

As we can see that  all the horizontal lines are in parallel to each other,

Alternative Interior Angle :  When two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent.

With the help of above theorem,

Angle of elevation from point A to B = Angle of depression from point B to A,

∠E and ∠D are interior opposite angles.

Then,  m ∠ E = m ∠ D

3x + 1 = 2(x + 8)  ( Given )

3x + 1 = 2x + 16

x = 15,

So, m∠ E = 3x + 1 = 45 + 1 = 46°

Hence,  m∠D = 46°

7. The measure of each angle is m∠ E = 20°, m∠ D = 20°.

By following same method as given above we will solve this question.

So, As we know that

Angle of elevation from point A to B = Angle of depression from point B to A,

∠E and ∠D are interior opposite angles.

Then,   m ∠ E = m ∠ D

5(x - 2) = (x + 14)

5x - 10 =  x + 14

  5x -x = 14 + 10

      4x = 24

        x = 24/4 = 6

So, m∠ D = (x + 14) = 6 + 14 = 20°

Hence, m ∠ E = 20°

no wizardry is needed, as the function is already there. we only need to use it.

(a)

find d, so that 162 - 6d = 0 (0 miles are left)

162 - 6d = 0

162 = 6d

d = 162/6 = 27

it will take them 27 days.
