let their number of sides of a regular polygon is 6 in its radius is 5,then find the length of the side.​

Answers

Answer 1

Step-by-step explanation:

area = n * a * ri / 2 , having ri - incircle radius (it's also an apothem - a line segment from the center to the midpoint of one of its sides) area = perimeter * ri / 2 , given ri and polygon perimeter.

The mailing tube shown below is 36 inches long, 6 inches wide, and 5.2 inches deep.
The bases are equilateral triangles. How much cardboard is used to make the tube?

Answers

The amount of cardboard = Surface area of a triangular prism = 679.2 in.²

What is the Surface Area of a Triangular Prism?

Surface area of a triangular prism = (perimeter of base × length of the prism) + (2 × Base Area)

= (S1 +S2 + S3)L + bh

The mailing tube is a triangular prism with an equilateral triangular base, and has the following given values:

s1 = 6 in.s2 = 6 in.s3 = 6 in.L = 36 in.b = 6 in.h = 5.2 in.

Plug the values into the surface area formula to find the amount of cardboard that would be used to make the tube:

Amount of cardboard = Surface area of a triangular prism = (6 + 6 + 6)36 + (6)(5.2) = 679.2 in.²

Answer:

r = 1.7389 in

Step-by-step explanation:

(A) Volume of hollow block = 540 in^3

(B) volume of block without Hollows = b×d×h

= 6 ×16 ×8

= 768 in^3

(C) volume of 3 hollows = 3 ×( pi ×r^2 h)

= 3 ×( pi ×r^2 ×8)

= 24 ×pi ×r^2

solve,

A = B - C

540 = 768- (24 ×pi ×r^2)

r^2 = (768- 540) / 24 pi

r = root(3.023943919)

An angle measures 132.6 more than the measure of a supplementary angle. What is the measure of each angle?

Answers

Answer:

Step-by-step explanation:

If the angle measures x, then the supplement measures 180-x.

This means x-132.6=180-x, and thus x=156.3

This means the angles measure 156.3 and 23.7 degrees.

If the price of a yo-yo in a shop increased by 20% and is now $18.00, what was the original price?​

Answers

So $18 would be 120%. This is because the yoyo is 100% and you increased by 20%. If this was a calculator question, you would do 18 / 120 than times by 100 to get 100%. Naturally it would just be 18/12 x 10 = 15. so $15 is 100% or the originally price.

Hope it helped :)

The original price was $15.00

The price of the yo-yo increased by 20% and went to $18.00. Assuming the original price is x, the original price would be:

18 = x × (1 + 20%)

18 = x × 1.20

18 = 1.20x

x = 18 / 1.20

x = $15.00

In conclusion, the original price was $15.00 but after the price increased by 20%, it went to $18.00.

Rewrite the whole as a fraction using  5  as the denominator :

   -4 =  ——  =  ——————

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

When a fraction equals zero

3.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 x+20

 ———— • 5 = 0 • 5

  5  

Now, on the left hand side, the  5  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  x+20  = 0

Solving a Single Variable Equation:

3.2      Solve  :    x+20 = 0

Subtract  20  from both sides of the equation :

                     x = -20

Answer:

x=-4.5 or -9/2

Step-by-step explanation:

The first step is to isolate x to do this you add 5 to both sides which then gives you -2x=9 the next step is to divide by negative 2 which would give you -9/2 which simplifies to -4.5.


The price of a calculator depends on the number of these calculators you buy.
The table gives information about the prices of this calculator.
Number of calculators
Price of each calculator
1-29
£3.85
30-99
£3.65
100 or more
£3.49
Mr Edwards wants to buy some of these calculators.
He has £200 to spend.
Work out the greatest number of calculators he can buy.

Answers

There are many ways you can approach this problem but the easiest and most understandable way is really simple,So we know that for the first 29 calculators he has to spend £3.85 on each.

So assuming he bought the entire 29 calculators he would've spent:

[tex]29 \times 3.85 = 111.65[/tex]

That leaves him with,

[tex]200 - 111.65 = 88.35[/tex]

Looking back at the prices i'm assuming there is no way he can reach 99 calculators with what he has left, so i will establish an equation that defines the number of calculators he can buy with the remaining £88.35.

Let c be the number of calculators he can still buy. Note that we are working in the 30-99 range so each calculator costs £3.65

[tex]88.35 = 3.65c[/tex]

[tex]c = \frac{88.35}{3.65} = 24.2[/tex]

So now we know he can still buy 24 calculators in addition to the 29 calculators, so in total he bought,

[tex]29 + 24 = 53[/tex]

Your answer would be 53 calculators.

What about the 0.2 remaining 'calculators',well that would be left over money which aren't sufficient to purchase an additional calculator+we were working with the 30-99 range meaning each one costs £3.65

[tex]0.2 \times 3.65 = 0.73[/tex]

So he bought 53 calculators and has 0.73£ remaining.

Answers

Answer:

the first

0 5

5 0

Step-by-step explanation:

the question should be : "which describes a POSSIBLE domain and range definition of the function and is inverse ?"

because this is just a matter of definition. the function itself would not suggest any limits.

and in that regard the function definition is basically irrelevant.

the domain of any basic function is the range of the inverse, and the range of the basic function is the domain of the inverse.

so, the second set of definitions is not possible, if we are really trying to define the inverse function.
