For a regular 17-gon, the measure of the internal angles is:
a = 158.8°
How to measure the internal angles?
The measure of the sum of the internal angles of a regular figure of N sides is:
(N - 2)*180°
For the case where N = 17, we have:
(17 - 2)*180° = 2,700°
That is the measure of the sum of the internal angles, and we have 17 of them, so the measure of each angle is:
2,700°/17 = 158.8°

For each value of x determine whether it is a solution
Hey !
Question :For each value of x determine whether it is a solution to 45 = -9 ( x + 5 )
Given :In the question we have given an equation i.e. :
45 = -9 ( x + 5 )In the question values of x are also given i.e. :
5-71-4To Determine :In this question we have to determine whether given value of x are solution fo the given equation or not .
How we have to solve this question :We are solving this question by substituting given value of x in the equation if equation satisfied then it means that the value for x is solution of the equation .
So Let's get started :1) Value of x as 5 :
45 = -9 ( x + 5 ) ( Given Equation )Now substituting value of x as 5 :
45 = -9 ( 5 + 5 )45 = -9 ( 10 )45 = -90But , 45 is not equal to -90Therefore , 5 is not the solution for equation .
2) Value of x as -7 :
45 = -9 ( x + 5 ) ( Given Equation )Now substituting value of x as -7 :
45 = -9 ( -7 + 5 )45 = -9 ( -2 )45 = 18But , 45 is not equal to 18Therefore , -7 is not the solution for equation .
3) Value of x as 1 :
45 = -9 ( x + 5 ) ( Given Equation )Now substituting value of x as 1 :
45 = -9 ( 1 + 5 )45 = -9 ( 6 )45 = -54But , 45 is not equal to -54Therefore , 1 is not the solution for equation .
4) Value of x as -4 :
45 = -9 ( x + 5 ) ( Given Equation )Now substituting value of x as -4 :
45 = -9 ( -4 + 5 )45 = -9 ( 1 )45 = -9But , 45 is not equal to -9Therefore , -4 is not the solution for equation .
So ,In there is no proper value of x that can be solution of the given equation .[tex] Keep \: Learning[/tex]

a) Patty Stacey deposits $2600 at the end of each of 5 years in an IRA. If she leaves the money that has accumulated in the IRA account for 25 additional years, how much is in her account at the end of the 30-year period? Assume an interest rate of 10%, compounded annually. (Round your answer to the nearest cent.)
$
(b) Suppose that Patty's husband delays starting an IRA for the first 10 years he works but then makes $2600 deposits at the end of each of the next 15 years. If the interest rate is 10%, compounded annually, and if he leaves the money in his account for 5 additional years, how much will be in his account at the end of the 30-year period? (Round your answer to the nearest cent.)
$
(c) Does Patty or her husband have more IRA money?
Answer:
From the question, Stacey deposits $2600 six times over a thirty year period since she makes the deposit every five years. Her amount accures by the formular. A = P(1+r/n)^nt. Where her principal P = $2,600. Rate, r =6% =0.06. Time = 30 years and the period of compounding per unit time, n = 6 years. So we have A =2, 600(1+(0.06/6))^(6*30) = 2, 600 (1 + 0.01)^(180) = 2600* 5.9958 = $15, 587. To the nearest cent we have $15, 590.

A cruise ship is 1480 feet from a light house off a Caribbean Island.
If the angle of elevation from the cruise ship to the top of the light
house is 4º, what is the height of the lighthouse? Round to the
nearest whole foot.
Answer:
104 feet
Step-by-step explanation:
To get the height of the lighthouse, we need to take the sine function of the anglesin4° = 0.07sin4° = h/1480⇒ h/1480 = 0.07⇒ h = 1480 x 0.07⇒ h = 103.6⇒ h = 104 feet6. Kayla is planning to buy a new phone. Rongers charges $0 for down payment plus $127 monthly fee. Fidoll charges $363 for down payment plus $94 monthly fee.
a) When will the two plans charge the same amount (the same number of months for both plans)?
b) If both plans are contracted for 2 years (24 months), which plan would you recommend to Kayla? Explain.
The two plans charge the same amount in 11 months.
The plan I would recommend if the plans are contracted for two months is the Fidoll plan.
When will the two plans charge the same amount?
The equation that represents the amount that would be paid by Kayla if she buys the phone from Rongers is : $127x
Where x represents the number of months
The equation that represents the amount that would be paid by Kayla if she buys the phone from Fidoll is : $363 + $94x
Where x represents the number of months
The two above equations would be equal when the plan charge the same amount: $363 + $94x = $127x
Combine similar terms
$363 = $127x - $94x
Add similar terms
$363 = $33x
Divide both sides by 33
x = 11 months
Which plan would be recommended if the plan is for 2 years?
Rongers: $127(24) = $3,048
Fidoll = $363 + $94(24) = $2619
I would recommend the Fidoll plan

Rewrite each equation without absolute value for the given conditions. y=|x-3|+|x+2|-|x-5| if -2
The equation y = |x-3| + |x+2| - |x-5| is an absolute value equation
The equivalent equation of y = |x-3| + |x+2| - |x-5| if -2 < x < 3 is y = x
How to rewrite the absolute value equation?The equation is given as:
y = |x-3| + |x+2| - |x-5|
The condition is given as:
if -2 < x < 3
Split and solve each term of the absolute value equation.
|x-3| = -(x - 3) = 3 - x....... because x < 3
|x+2| = x + 2 because -2 < x
|x-5| = -(x - 5) = 5 - x....... because x < 5
So, we have:
y = |x-3| + |x+2| - |x-5|
This gives
y = (3 - x) + (x + 2) - (5 - x)
Open the brackets
y = 3 - x + x + 2 - 5 + x
Evaluate the like terms
y = x
Hence, the equivalent equation of y = |x-3| + |x+2| - |x-5| if -2 < x < 3 is y = x

Find the value of x of 2x 110° (x + 10)°
Answer:
50°
Step-by-step explanation:
the sum of the angles of a quadrilateral is 360°
so
2x + 110 + x + 10 + 90 = 360
2x + x = 360 - 110 - 10 - 90
3x = 150
x = 150 : 3
x = 50°
-------------------------
check
50 + 10 + 2 * 50 + 110 + 90 =
360°.
the answer is good
Answer:
x = 50
2x = 110°
(x + 10)° = 60°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral is 360°
⇒ 2x° + (x + 10)° + 110° + 90° = 360°
⇒ 2x° + x° = 360° - 110° - 90° - 10°
⇒ 3x° = 150°
⇒ x = 50
Substitute found value of x into the expressions and solve:
⇒ 2x° = 2(50)° = 110°
⇒ (x + 10)° = (50 + 10)° = 60°

i believe _=6 (the horizontal side, as it says on the picture,) | = 6 (the vertical side,) and \ = 8.48 (the diagonal)
Step-by-step explanation:
To find the diagonal, you have to use the Pythagorean Theorem, which is a^2 + b^2 = c^2
So, a and b both equal 6, square both of those, you got 36 for each.
Now, add them together and youll get 72
The square root of 72 is around 8.48

Rebecca and Blake decide to roll a pair of fair 6-sided dice to determine who has to clean their dishes.
If the sum is 5 or 6, then Rebecca will clean the dishes.
If the sum is 8 or 9, then Blake will clean the dishes.
If the sum is anything else, they'll roll again.
Is this a fair way to decide who cleans the dishes? Why or why not?
Answer:
it's not fair
Step-by-step explanation:
... if Rebecca rolled the dice it's most likely going to give a 6 or a higher number if Blake rolled the same too would have happened thus it would be fair if the dice was 3 sided
Rebecca and Blake decide to roll a pair of fair 6-sided dice to determine who has to clean their dishes. If the sum is 5 or 6, then Rebecca will clean the dishes. If the sum is 8 or 9, then Blake will clean the dishes. If the sum is anything else, they'll roll again. This is a fair method of decision making by law of probability because both Rebecca and Blake are equally likely to wash the dishes.
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
Total number of observations in sample space when a pair of dice is rolled = 6² = 36
Number of observations where sum is 5 or 6 = 9
((1,4)(4,1)(2,3)(3,2)(1,5)(5,1)(4,2)(2,4)(3,3))
Probability that Rebecca will clean the dishes = 9/36 = 0.25
Number of observations where sum is 8 or 9 = 9
((2,6)(6,2)(3,5)(5,3)(4,4)(3,6)(6,3)(4,5)(5,4))
Probability that Blake will clean the dishes = 9/36 = 0.25
Since, the probabilities of Rebecca and Blake cleaning the dishes are equal, the method of decision making is fair.
