2 answers:

7 0

<span>sum of the interior angles of a polygon = (n - 2) x 180
</span>hexagon has 6 sides , in this case n = 6
so
(6-2) x 180
= 4 x 180
= 720

answer

Please help with a, b, c

Elanso [62]

Answer:

a. p(n) is a function of n

b. p(2)=12.50

c. {0, 1, 2, 3, 4}

Step-by-step explanation:

A function is a rule or equation the p(n) depends on the variable n. We write it as p(n) is a function of n. It can also be written in symbols using p(input)=output for (input,output). We write p(2)=12.50. Lastly, every function has a domain which consists of input values or n values used. Here it is 0, 1, 2, 3, 4.

A baseball has a 45 cm diameter. what is the volume of the contents of the ball

Morgarella [4.7K]

First you need to find the radius. To do that you need to divide the diameter by two;

45 / 2 = 22.5

Then you plug the radius in the formula for a sphere. Which is...

V = (4 / 3)πr^3
First you need to find the volume with out pi

V = (4/3) π (45)^3
V= π (4/3) (91,125)
Your answer with out pi is...
V= (68,343.75) π cm^3
And with pi is...
V = 214,708.22 cm^3

Mr. Litterski creates a ball from rubber bands.

kupik [55]

Answer:

The surface area of the ball is of 29 square inches.

The volume of the ball is of 15 cubic inches.

Step-by-step explanation:

The ball has an spherical format:

Circumference of a sphere:

The circumference of a sphere is 6.2832 times the radius.

Surface area

$A = 4\pi r$

In which r is the radius.

Volume:

$V = \frac{4\pi r^3}{3}$

The circumference of the ball is 9.4 inches.

So the radius is:

$6.2832r = 9.4$

$r = \frac{9.4}{6.2832} = 1.53$

Surface area

$A = 4\pi(1.53)^2 = 29.3$

Rounding to the nearest unit, the surface area of the ball is of 29 square inches.

Volume:

$V = \frac{4\pi (1.53)^3}{3} = 14.9$

Rounding to the nearest unit, the volume of the ball is of 15 cubic inches.

What is a simple rule for adding and subtracting like fractions

konstantin123 [22]

Here is you're answer:

One of the most simple rules when solving fractions is to "find the common denominator."

Example:

$\frac{1}{2} + \frac{1}{2} =$
Find the common denominator:
Common denominator is 2:
$1 +1=2$
$= \frac{2}{2} = 2$

So, in order to solve fractions you first have to find the common denominator of each fraction, then you have to add or subtract the numerators to equal you're answer.

Hope this helps!

Some airlines have restrictions on the size of items of luggage that passengers are allowed to take with them. Suppose that one

olga_2 [115]

Answer:

Length = Width = Height = 64 ; Luggage Box is a CUBE

Step-by-step explanation:

Given : Length (L) + Width (W) + Height (H) ≤ 192 ; & Length = Width

Volume ( V )of luggage [Cuboid] = L.W.H

Since L = W :

V = L.L.H → V = L^2H

L + L + H = 192 → 2L + H = 192 → H = 192 - 2L

Putting value of 'H' in 'V'

V = L^2 (192 - 2L) → V = 192L^2 - 2L^3

Maximising volume function , differentiating it w.r.t 'L'

dV / dL = 2(192 L) - 3 (2L^2) → = 384L - 6L^2

dV / dL = 384L - 6L^2 = 0

384L = 6L^2 → 384 = 6L

L = 384 / 6 → L = 64 ; W also = 64

Putting value of L in 1st given sum equation : 2L + H = 192

2 (64) + H = 192

128 + H = 192 → H = 192 - 128 → H = 64

Since L = W = H = 64 ; Luggage bag is a Cube
