there are 5+3=8 parts in total

800 divide by 8 parts = 100 in each part

k800 is 5:3 is k500: k300

Find the sum of the measures of the interior angles:

Tresset [83]

The sum of the measures of the interior angles

The sum of interior angles of any polygon can be foud wuth the following general formula

Sum of interior angles = (n-2) \ times 180^{\circ}

where n is the number of sides

1. Nonagon

The Nonagon is a polygon with 9 sides. then,

n = 9

Sum of interior angles of Nonagon

= $(9-2) \times 180^{\circ}$

= $(7) \times 180^{\circ}$

= $1260^{\circ}$

2.Pentagon

The Pentagon is a polygon with 5 sides. then,

n = 5

Sum of interior angles of Pentagon

= $(5-2) \times 180^{\circ}$

= $(3) \times 180^{\circ}$

= $540^{\circ}$

3. 11-gon

The 11-gon is a polygon with 11 sides. then,

n = 11

Sum of interior angles of 11-gon

= $(11-2) \times 180^{\circ}$

= $(9) \times 180^{\circ}$

= $1620^{\circ}$

4. 18-gon

The 18-gon is a polygon with 18 sides. then,

n = 18

Sum of interior angles of 18-gon

= $(18-2) \times 180^{\circ}$

= $(16) \times 180^{\circ}$

= $2880^{\circ}$

5. 38-gon

The 38-gon is a polygon with 38 sides. then,

n = 38

Sum of interior angles of 38-gon

= $(38-2) \times 180^{\circ}$

= $(36) \times 180^{\circ}$

= $6480^{\circ}$

6.56-gon

The 56-gon is a polygon with 56 sides. then,

n = 56

Sum of interior angles 56-gon

= $(56-2) \times 180^{\circ}$

= $(54) \times 180^{\circ}$

= $9720^{\circ}$

I need help with this math questions can anyone help Thanks. Can u help me on #1 and#2

Fynjy0 [20]

1.
yes
x is number of group acts
y is number of indivual acts

2. I would eliminate x by multiplying 2nd equation by -3 then adding

12x+6y=120
-12x-3y=-90 +
0x+3y=30

3y=30
divide by 3
y=10

sub
4x+y=30
4x+10=30
4x=20
divide 4
x=5

each group act takes 5 mins and each individual takes 10 minutes

The formula f(x + 1) = Two-thirds(f(x)) defines a geometric sequence where f(1) = 18. Which explicit formula can be used to mode

astraxan [27]

Answer:

The explicit formula is Tn = 18[(2/3)^(n-1)]

Where n is the term we are looking for

Step-by-step explanation:

Here, we want to get an explicit formula to model the equation

Now, F(2) = 2/3 * f1 = 2/3 * 18 = 12

F(3) = 2/3 * f(2) = 2/3 * 12 = 8

F(4) = 2/3 * F(3) = 2/3 * 8 = 16/3

F(5) = 2/3 * 16/3 = 32/9

Thus, seeing how the equations are progressing, we can definitely see a pattern.

That is Tn = (2/3)^(n-1)(18)
