Answer:

9 sides

Step-by-step explanation:

Formula for finding interior angles of all polygons : 180 ( n - 2) / n = A

(n being the amount of sides it has)

This information is important so you can plug in the numbers that you already know

We know that the interior angle measures to 140 degrees

180 (n - 2) / n = 140

multiply both sides by "n"

(n - 2) x 180 = 140n

Distribute 180 to what's inside the parenthesis

180n - 360 = 140n

Subtract 140n and add 360 to each side (which just moves 360 to the other side of the "="

40n = 360

Divide 40 by both sides

n = 9

Answer:

x ≈ 17.5

Step-by-step explanation:

using Pythagoras' identity in the right triangle.

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

x² = 9² + 15² = 81 + 225 = 306 ( take square root of both sides )

x = [tex]\sqrt{306}[/tex] ≈ 17.5 ( to the nearest tenth )

Step-by-step explanation:

1 km² = 1km×1km = 1000m × 1000m = 1000000 m²

5 km² = 5000000 m²

so, he has to pay 5000000p as tax.

The amount of tax the farmer must pay is 50000 Rupees.

A compulsory contribution the government has levied on people's income is called the tax , It is of various types and the money accumulated from that is used for the development of the nation.

It is given that the farmer has an area of 5 km²

The farmer must pay 1p tax for each m² of land he owns.

5km² = 5 * (1000)² m²

Area = 5 *10⁶ m²

The amount of tax the farmer needs to pay is

= 1* 5* 10⁶

= 5000000 p

100p = 1 rupees

= 50000 Rupees

Therefore the amount of tax the farmer must pay is 50000 Rupees.

Answer:

x = 43

Step-by-step explanation:

the angle in the triangle is vertically opposite 47° and is congruent

the sum of the 3 angles in the triangle = 180° , then

90 + 47 + x = 180

137 + x = 180 ( subtract 137 from both sides )

x = 43

Answer:

21.9

Step-by-step explanation:

When rounding to the nearest tenth, we are rounding to 1 decimal place.

If the number in the hundredth place is 5 or more, we round up.

If the number in the hundredth place is less than 5, we round down.

17.26 rounded to the nearest tenth is 17.3

as 6 is in the hundredth place, so we round 2 tenths up to 3 tenths.

4.556 rounded to the nearest tenth is 4.6

as 5 is in the hundredth place, so we round 5 tents up to 6 tenths.

Therefore, 17.3 + 4.6 = 21.9

Answer:  Janet's overtime pay is: " $ 17. 19 per hour ."
  →  and specifically:  " $ 77.36 " ;
        →  [for the 4.5 hours of overtime pay worked Within the total 44.5 hours Janet worked within the particular Monday to Friday workweek as given within this particular Brainly question/].
__________

Step-by-step explanation:
__________
Note:  Let us assume that up to and including "40 hours within a workweek" is paid as a "base rate of regular pay"—and that any hours worked over "40 hours" count as "overtime hours.."

Furthermore: Let us assume that "overtime pay" is paid at the rate of "time and a half".  This means that any and all hours worked over 40 hours are "overtime hours"—and that these "overtime hours" are paid at the rate at "1.5 times" the rate of the regular hourly rate.
__________

Note: A secretary is typically a job that is paid by the "hour"; as opposed to certain management positions (which are paid by "salary").
→ So, we shall assume that the secretary, "Janet Henderson", is a "hourly worker"—who is "non-exempt" from being paid "overtime."
→ So, first, given:  Janet Henderson worked Monday through Friday for a total of "44.5 hours."
Note: This amount: "44.5 hours" ; is over "40 hours."
            {i.e. " [44.5 hours]  >  [40 hours] ".}.

Note:  Any and all hours Janet earned in excess of 40 hours are considered : "overtime hours."
Now:  Let us calculate the number of "overtime hours":
   → We subtract: "40"; from the actual amount of hours Janet worked [which is "44.5 hours"] ;
    →   " (44.5 − 40) hours " ;
          =  " 4.5 hours " (of overtime worked).
Now, we are given that Janet's regular pay is:  " $ 11.46 per hour."
→  To solve: Find the value of:   " (1.5) * ($ 11.46) " ;
Method 1) Use a calculator:  to get:  " 17. 19 " .
    → The answer is:  " $ 17.19 per hour."

Method 2)
    →  " 11.46 + [(1/2)* 11.46] " ;

             =  "11.46 + (11.46 /2)" ;  
Note: Let us start by calculating:  "(11.46 / 2)" ; that is:  "(11.46 ÷ 2)" .
Method A) Note:  " 11.46 ÷ 2 = 5.73 " ; → {Using a calculator.}.
Method B)  
Using long division; to get:  "5.73 " ; as follows:

            5.73
      2⟌ 11.46

        - 10    
             1.46
        -    1.4  
             0.06
        -    0.06
             0.00 .

Now:  We can write the expression:  
 →   " 11.46 + [(1/2)* 11.46] " ;  as:
 →     " 11.46 + 5.73 " ; & then calculate (add the values);

to get" 11.46 + 5.73 = " 17. 19 "

So;  Janet's overtime pay is $17.19 per hour.

Other:
To find the specific, exact dollar amount of overtime pay earned for the "4.5 hours" of overtime worked in the particular Monday to Friday workweek as given within the actual question:

→ We multiply this amount—"17.19 dollars"— by the number of overtime hours that Janet worked—"4.5 hours"—as follows:
→  "   [tex]\frac{17.19 dollars}{hr} *\frac{4.5 hr}{1}[/tex]  " ;  
→  The units of "hr" ["hour(s)"] cancel out to: "1 ";  
          →  {since:   ["hr/ hr " = 1 .] } ;
And we have:  
→ " (17.19 dollars * 4.5)  = _?  dollars " ;  Solve for: {the "_?_"  value.}:
Using a caculator:  We get:
   →  77.355 dollars;  ⇒  write as:  $77.355 ;  round to:  " $ 77.36 " .

If the area of a semicircle and an isosceles triangle is 56.55 cm² and 18 cm². Then the area of the shaded region will be 38.55 cm².

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Then the area of the shaded region will be given by the difference between the area of the semicircle and the area of the isosceles triangle.

The area of the shaded region will be

Shaded area = area of semicircle - area of isosceles triangle

Then the area of the semicircle will be

Semicircle area = π 6² / 2

Semicircle area = π36/2

Semicircle area = 56.55 square cm.

The area of the isosceles triangle will be

Isosceles triangle area = 2 × (1/2) × 6 × 6 sin30°

Isosceles triangle area = 6 × 6 × 0.5

Isosceles triangle area = 18 square cm

Then the area of the shaded region will be

Shaded area = 56.55 - 18

Shaded area = 38.55 square cm

The expression written as a product is:

[tex](-4.5)^6*(-4.5)^{-2}[/tex]

And written as a power:

[tex](-4.5)^4[/tex]

Here we need to remember the two rules:

[tex]a^n = \frac{1}{a^{-n}}[/tex]

[tex]a^n*a^m = a^{n + m}[/tex]

Using the first one, we can write the quotient as a product:

[tex]\frac{(-4.5)^6}{(-4.5)^2} = (-4.5)^6*(-4.5)^{-2}[/tex]

Now we can use the second property to write the expression as a single power, we will get:

[tex]\frac{(-4.5)^6}{(-4.5)^2} = (-4.5)^6*(-4.5)^{-2} = (-4.5)^{6 - 2} = (-4.5)^4[/tex]

The measure of angle IJG in the inscribed quadrilateral is calculated as: 110°.

The opposite angles in a inscribed quadrilateral in a circle are said to be equal to 180 degrees, that is, they are supplementary.

angle IJG and angle GHI are opposite angles, therefore:

Angle IJG = 180 - angle GHI

Angle IJG = 180 - 70

Angle IJG = 110°
