Step-by-step explanation:
125=5*5*527=3*3*33√125=53√125*27= 3√5*5*5*3*3*35*315-1286250Un avion vuela ciudad a hacia la ciudad b, a una distancia de 150 millas, y despues vira con un angulo de 50° y se dirige hacia la ciudad C, a una distancia de 100 milllas,¿Con que angulo debe virar el piloto en la ciudad C para regresar a la ciudad A?
Answer:
El piloto debe virar a 87.7° en la ciudad C para regresar a la ciudad A.
Step-by-step explanation:
Podemos encontrar el angulo que debe virar el piloto en la ciudad C para regresar a la ciudad A usando el Teorema del coseno:
[tex] (AC)^{2} = (AB)^{2} + (BC)^{2} - 2(AB)(BC)cos(50) [/tex]
[tex] (AC)^{2} = (150 mi)^{2} + (100 mi)^{2} - 2(150 mi)(100 mi)cos(50) [/tex]
[tex] (AC) = 115 mi [/tex]
Ahora podemos encontrar el ángulo entre los puntos C y A (AC) usando la ley de los senos:
[tex] \frac{sin(50)}{AC} = \frac{sin(\alpha)}{AB} [/tex]
[tex] \frac{sin(50)}{115 mi} = \frac{sin(\alpha)}{150 mi} [/tex]
[tex] \alpha = 87.7 [/tex]
Por lo tanto, el piloto debe virar a 87.7° en la ciudad C para regresar a la ciudad A.
Espero que te sea de utilidad!
El piloto debe virar con un ángulo de 61° 42' 12'' para regresar a la ciudad A.
Dado que un avión vuela desde la ciudad A hacia la ciudad B, a una distancia de 150 millas, y después vira con un ángulo de 50° y se dirige hacia la ciudad C, a una distancia de 100 millas, para determinar con que ángulo debe virar el piloto en la ciudad C para regresar a la ciudad A se debe realizar el siguiente cálculo, aplicando las teorías del seno y el coseno:
Lado A = 150Lado B = 100Lado C = ???Angulo B = 50√(150² + 100² - 2 x 150 x 100 x cos 50) = Lado C√(22500 + 10000 - 19283.62) = Lado C√13216.3717094 = Lado C114.96 = Lado CSen C/114.96 = Sen 50/100Sen C = (114.96 x Sen 50) /100Sen C = 0.8806C = 61,72100 = 6072 = X72 x 60 / 100 = X42,2 = X100 = 60 20 = X20 x 60 / 100 = X12 = X61° 42' 12'' = Ángulo CPor lo tanto, el piloto debe virar con un ángulo de 61° 42' 12'' para regresar a la ciudad A.

okay so angle O is connected to arc GU. to find angle O you musit find Arc GU
if Arc GO is 48 degrees and arc OU is 107 degrees, then you add those together.
107 +48=155
a circle has a total of 360 degrees
so 360-155= 205
205 is arc GU
205 divided by 2 will give you angle O
O is 102.5 degrees

Sharyce put some money in a savings account that paid 2.7% simple interest. After a year, the account was worth $7,890.44. What was the amount Sharyce originally deposited?
Step-by-step explanation:
P=A/(1+rt)
P = 7890.44 / ( 1 + (0.027 × 1)) = 7682.9990262902
P = $7,683.00
Sharyce originally deposited $7,683 into the savings account.
What is the formula for simple interest?The formula for simple interest is as follows:
I = Prt
Where I is the interest earned, P is the principal (the amount originally deposited), r is the interest rate (as a decimal), and t is the time (in years).
We know that after a year, the account was worth $7,890.44, so the interest earned is:
I = $7,890.44 - P
We also know that the interest rate is 2.7% or 0.027 (as a decimal), and the time is 1 year.
Substitute these values into the formula and solve for P:
I = Prt
$7,890.44 - P = P x 0.027 x 1
$7,890.44 - P = 0.027P
$7,890.44 = 1.027P
P ≈ $7,683
Therefore, Sharyce originally deposited $7,683 into the savings account.

Answer:
1/2
Step-by-step explanation:
other answer was wrong
The value of sin30 is [tex]\frac{1}{2}[/tex]
What is a 30-60-90 triangle?The 30-60-90 triangle is called a special right triangle as the angles of this triangle are in a unique ratio of 1:2:3.
According to the given sum:
In theory, we know,
For a 30-60-90 triangle, the sides opposite to 30° is x , side opposite to 60° is x*[tex]\sqrt3}[/tex] and the side opposite to 90° is 2x
Therefore,
If x = 1,
The sides are [tex]\sqrt{3},2,1[/tex] where,
perpendicular = [tex]\sqrt{3}[/tex]
Base = 1
Hypotenuse = 2
We know sinФ = [tex]\frac{perpendicular}{Hypotenuse}[/tex]
But in the case of sin30 , we have to take perpendicular as 1 and hypotenuse as 2, that is the angle has to be at base. If it was sin60, we would have taken perpendicular as [tex]\sqrt{3}[/tex] and hypotenuse as 2.
Therefore,
Sin30 = [tex]\frac{1}{2}[/tex]
Hence, we can conclude that the value of sin30 is [tex]\frac{1}{2}[/tex].

The regular price of a video game is $59.,95. This week it is on sale for 15% off. What does the game cost this week (before taxes)
Answer: $50.96
Step-by-step explanation:
The regular price of a video game is $59.95 and we are told that this week it is on sale for 15% off.
The game cost this week before taxes will be:
= 59.95 - (15% × 59.95)
= 59.95 - (0.15 × 59.95)
= 59.95 - 8.9925
= $50.9575
= $50.96

Which expression shows 56x+40y-48z written as a product of the greatest common factor and one other factor
Answer:
Step-by-step explanation:
You have not provided the choices.
Factor each term into powers of primes and variables:
56x = 2³·7x
40y = 2³·5y
48z = 2⁴·3z
Greatest common factor = 2³ = 8
56x + 40y - 48z = 8(7x + 5y - 6z)
