Find the measure of each interior and exterior angle of a regular 40-gon.
Answer:
All exterior angles will add up to 360 degrees, regardless of the number of sides.
For the sum of the interior angles, use this formula:
The sum of the interior angles = (N x 180) - 360
Where N = the number of sides
So, (40 x 180) - 360 = 6840 degrees
The measure of each interior and exterior angle of a regular 40-gon are [tex]171^\circ[/tex] and [tex]9^\circ[/tex] respectively.
Important information:
The given shape is a regular 40-gon.Interior and exterior angles:Interior angle of a regular polygon is [tex]\dfrac{(n-2)\times 180^\circ}{n}[/tex], where n is the number of sides.
A regular 40-gon has 40 sides. So, the measure of each interior angle is:
[tex]\dfrac{(40-2)\times 180^\circ}{40}=38\times 4.5^\circ[/tex]
[tex]\dfrac{(40-2)\times 180^\circ}{40}=171^\circ[/tex]
Exterior angle of a regular polygon is [tex]\dfrac{360^\circ}{n}[/tex], where n is the number of sides.
A regular 40-gon has 40 sides. So, the measure of each exterior angle is:
[tex]\dfrac{360^\circ}{40}=9^\circ[/tex]
Therefore, the measure of each interior and exterior angle of a regular 40-gon are [tex]171^\circ[/tex] and [tex]9^\circ[/tex] respectively.

Write the equation of the line that passes through each pair of point (1,2) (-1,-3)
Answer: y = 3
Step-by-step explanation:
So, we must find an equation of a line that passes through these two points such that we find the slope first as,
m = (3-3) / (2-(-1)) = 0 / 3 = 0. Then we bring up the point-slope form of an equation to find the line such that
y - y1 = m(x - x1). Next,
y - 3 = 0(x - (-1))
y - 3 = 0..............Then add 3 such that the equation of a line is

If you deposit $24,500 into a bank account paying 6% annual interest compounded
semi-annually for 5 years, how much interest will you earn? Round to the nearest cent.
Answer:
$7,719.33
Step-by-step explanation:
$24,500 x 0.06 = $1,470
($24,500 + $1,470) x 0.06 = $1,558.20
($24,500 + $1,558.20) x 0.06 = $1,563.49
($24,500 + $1,563.49) x 0.06 = $1,563.81
($24,500 + $1,563.81) x 0.06 = $1,563.83
$1,470 + $1,558.20 + $1,563.49 + $1,563.81 + $1,563.83 = $7,719.33
The equation for compound interest is A=P(1+rn)nt, where P is the initial amount invested, r is the interest rate as a decimal, n is the number of times compounded annually, and t is the number of years.
Determine the value of the account if the initial investment is $8,000 compounded monthly at a rate of 6% after 10 years.

An oven is set at 176.8°C. Marla increases the temperature by 23.8°C.
What is the final oven temperature?
Answer:
200.6 degrees Celsius
We have the given number, 176.8 degrees Celsius, and we add or increase it by 23.8 degrees.
176.8 + 23.8 = 200.6
Our final answer is 200.6 degrees Celsius.

Suppose that a phone that originally sold for $800 loses 3/5 of its value each year after it is released.
After 2 years, how much is the phone worth?
Write an equation for the value of the phone, , years after it is released.
Answer:
It will be worth $128.
Step-by-step explanation:
After 1 year, 3/5 of 800 is 480 which leaves the value at $320, and then after 2 years, 3/5 of 320 is 192. 320-192 leaves the value at $128.

PLEASE HELP!!! Find the slope of the line that passes through the points (-1,7) and (0,-3).
Answer:
-10
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-3-7)/(0-(-1))
m=-10/(0+1)
m=-10/1
m=-10
Answer:
The slope is -10.
Step-by-step explanation:
Goal
Find the value of m/Find the slope.Given
Two coordinate points which are (-1,7) and (0,-3).Step 1
Use the slope formula which is rise over run also known as changes of y over changes of x.[tex] \large \boxed{m = \frac{y_2-y_1}{x_2-x_1} }[/tex]
From the given coordinate points, substitute the values in the formula.
[tex]m = \frac{7 - ( - 3)}{ - 1 - 0} \\ m = \frac{7 + 3}{ - 1} \longrightarrow \frac{10}{ -1} \\ m = - 10[/tex]
Therefore, the value of m or slope is -10.
Name the steps of solving 5x+4=40
Answer:
Step-by-step explanation:
Simplifying
5x + -4 = 40
Reorder the terms:
-4 + 5x = 40
Solving
-4 + 5x = 40
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 5x = 40 + 4
Combine like terms: -4 + 4 = 0
0 + 5x = 40 + 4
5x = 40 + 4
Combine like terms: 40 + 4 = 44
5x = 44
Divide each side by '5'.
x = 8.8
Simplifying
x = 8.8

the sequence of the numbers below is missing an eighth value. which of the following is the missing value? sequence: 5, 6, 8, 11, 15, 20, 26, __, 41
Answer:
D - 33
Step-by-step explanation:
From 5 to 6, the number is increasing by 1. Then from 6 to 8, it increases by 2. From 8 to 11 it increases by 3. This pattern continues throughout the entire sequence. Since between 20 and 26, it increases by 6, 26+7 should equal the number between 26 and 41. This number would be 33.
