The measure of an exterior angle of a regular polygon is given below. Find the measure of an interior angle. Then find the number of sides. 20
Answers
Answer:
Internal angle = [tex]160^\circ[/tex]
Number of sides = 18
Step-by-step explanation:
Given that:
We have a regular polygon with number of sides unknown.
Measure of an exterior angle of the polygon = [tex]20^\circ[/tex]
To find:
Measure of an interior angle and the number of sides of the polygon?
Solution:
Let us have a look at the relation of sum of external angles.
Sum of one internal angle and its corresponding external angle = [tex]180^\circ[/tex]
Internal angle + external angle = [tex]180^\circ[/tex]
Internal angle = [tex]180^\circ[/tex] - [tex]20^\circ[/tex] = [tex]160^\circ[/tex]
Sum of all the external of a regular polygon = [tex]360^\circ[/tex]
All the external angles will be equal because it is a regular polygon.
Let the number of sides = [tex]n[/tex]
Therefore,
[tex]n \times 20^\circ = 360^\circ\\\Rightarrow n = 18[/tex]
Therefore, the answers are:
Internal angle = [tex]160^\circ[/tex]
Number of sides = 18

Step-by-step explanation:
Un comerciante compro un lote de 15 calculadoras a 40 dolares cada una .Vendio 5 de ellas ,a orecio de promoción por100 dolares .Calcula el precio de venta de cada una de las restantes calculadoras para que gane 150 en la operación
Answers
The selling price of each of the remaining calculators should be $65 so that the merchant makes a profit of $150 in the entire operation.
The merchant bought a batch of 15 calculators at $40 each, so the total cost of the batch is:
Cost price = 15 calculators × $40/calculator
= $600
The merchant sold 5 calculators at a promotional price of $100 each.
So, the revenue from selling these 5 calculators is:
Revenue = 5 calculators × $100/calculator
= $500
Now, we need to calculate the profit made from the sale of these 5 calculators:
Profit = Revenue - Cost price
Profit = $500 - $600
= -$100 (Negative because the merchant incurred a loss on these 5 calculators)
The merchant wants to make a profit of $150 in the entire operation. So, adding the profit from selling the first 5 calculators:
Desired profit = $150
Current profit = -$100
Additional profit needed = Desired profit - Current profit
Additional profit needed = $150 - (-$100)
= $250
The merchant has 15 - 5 = 10 calculators left to sell.
We need to distribute the additional profit of $250 among the remaining 10 calculators:
Additional profit per calculator = Additional profit needed / Number of remaining calculators
Additional profit per calculator = $250 / 10 calculators
= $25
Now, let's calculate the selling price of each of the remaining calculators:
Selling price = Cost price + Additional profit per calculator
Selling price = $40 + $25 = $65
So, the selling price of each of the remaining calculators should be $65.

Four siblings buy a gift for their father on his birthday. Each sibling contributes (pays) the same amount of money towards the gift.
The gift ends up coming to $63 and after paying for the gift, there is some money left over which the siblings equally split.
Write an expression to represent the amount of money each sibling will get back after the gift is paid for. Use x to represent the amount of money paid by each sibling.
If each sibling contributed $18 towards the gift, how much money did each sibling get back?
tip: they have paid a total of 40 dollars, so subtract what they bought, which should be 3 times each of the items added together.
Answers
Answer:
63÷4=$15.75(each sibling gave which made it up to $63)
63-40=$23(amount added together-amount paid)
$23÷4=$5.75(each sibling got back)
63-5.75x
if each contributed $18:
18×4=$72(each contribute 18 dollars so multiply by 4 because 4 siblings)
72-40=32(minus 40 from amount they contributed)
32÷4=$8(divide by 4 to see what each sibling got)
Each sibling got back $8

Answer:Simplifying
(5x + -6)(5x + -3) = 0
Reorder the terms:
(-6 + 5x)(5x + -3) = 0
Reorder the terms:
(-6 + 5x)(-3 + 5x) = 0
Multiply (-6 + 5x) * (-3 + 5x)
(-6(-3 + 5x) + 5x * (-3 + 5x)) = 0
((-3 * -6 + 5x * -6) + 5x * (-3 + 5x)) = 0
((18 + -30x) + 5x * (-3 + 5x)) = 0
(18 + -30x + (-3 * 5x + 5x * 5x)) = 0
(18 + -30x + (-15x + 25x2)) = 0
Combine like terms: -30x + -15x = -45x
(18 + -45x + 25x2) = 0

18 + -45x + 25x2 = 0

Answers
Given :
A cylindrical tank with radius 3m is being filled with water at a rate 4m³/min.
To Find :
How fast is the height of the water increasing.
Solution :
We know, volume of cylinder is given by :
[tex]V = \pi r^2h[/tex] ....1)
Also, we have given that, [tex]\dfrac{dV}{dt} = 4 \ m^3/min[/tex] .
Differentiating equation 1) w.r.t t we get :
[tex]\dfrac{dV}{dt} =3^2 \pi \dfrac{ dh }{dt}\\\\\dfrac{dh}{dt} = \dfrac{4}{3^2 \times \pi}\\\\\dfrac{dh}{dt} = 0.141 \ m/min[/tex]
Therefore, the height of water is increasing at a rate of 0.141 m/min.
