How to find y in angle sum theorem

Svetach [21]

Answer:

y = 90°

Step-by-step explanation:

110° is the measure of exterior angle of bigger triangle.

-> (x + x) + 70° = 110° (By exterior angle theorem)

-> 2x = 110° - 70°

-> 2x = 40°

-> x = 40°/2

-> x = 20°

y is the measure of exterior angle of smaller triangle.

-> y = x + 70° (By exterior angle theorem)

-> y = 20° + 70°

-> y = 90°

Sequence problem!! Help!

ziro4ka [17]

a is the fifth term of a sequence. It represents the value of a depreciating

5 asset (your car) after 5 years have gone by since its purchase.

24,000 (really, $24,000) represents the initial value of the car.

(3/4) is the common ratio. Since (3/4) is between 0 and 1, we know the car is depreciating (losing value) each year, and that the value of the car at the end of this year is (3/4) times the previous value.

Após recuperar-se de uma cirurgia, o treinador da corredora Andrea estipulou um plano de treinamento diário: correr 500 metros n

user100 [1]

Explicación paso a paso:

La distancia recorrida el primer día = 500 m

Si aumenta la distancia en 200 m diariamente, entonces el total corrido diariamente formará una progresión aritmética con el último término de 10 km (10,000) como se muestra;

500, (500 + 200), (500 + 200 + 200) ... 10,000

500, 700, 900 ... 10,000

para que sepamos el número total de días usados para la carrera, usaremos la fórmula para calcular el enésimo término de una secuencia aritmética como se muestra;

$T_n = a+(n-1)d$ where;

n es el número de términos

a es el primer término de la secuencia

d es la diferencia común

Dado a partir de la secuencia:

a = 500

Tn = 10,000

d = 700-500 = 900-700 = 200

Sustituir en la fórmula y calcular el valor de n

$10,000 = 500+(n-1)*200\\10,000 = 500+(200n-200)\\10,000 = 500-200+200n\\200n = 10,000-300\\200n = 9,700\\n = 9,700/200\\n = 48.5$

Andrea habría alcanzado los 10.000km tras 48,5 días de carrera
