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

I need help plss!! I don’t understand
MA_775_DIABLO [31]

Since it says what the area of the circle is, you need to work the problem backwards from finding the area. So it would be 100 ÷ 3.14 = 31.84 that is the radius. Next you need to find the diameter, so 31.84 × 2 = 63.68. Now you multiply 63.68 × 3.14 = 199.95, round that to 200, divide 200 ÷ 2 = 100 ÷ 2 = 50 miles

Answer= 50 miles
